Illicit Discharge Detection, Elimination, and Enforcement
Response Plan
Each of the following sections describes detailed steps MSD staff follows in preparing for and conducting
field surveys, responding to complaints, and eliminating illicit discharges.
Preparation
Pre-field preparation for detecting and effectively eliminating illicit discharges is essential. Whether
preparing for a routine channel survey or responding to a complaint, weather, location review, and gear,
are among many factors to consider before heading out in the field.
Channel Surveys
• Review and prepare maps
Refer to the following Priority Area section and review geographic information system (GIS)
stormwater maps of watersheds and stream segments. Review selected maps for the day’s
scheduled survey segment and prepare field computer tablet and relevant GIS maps/layers,
including infrastructure/outfalls, NPDES points, industrial users, FSEs, no-entry points, septic
tanks, and lateral work orders. Review maps for surrounding land use and be aware of what
kinds of pollutants you may expect to run into, and sources/activities. Refer to Appendix for
detailed tablet operation steps.
The stormwater system within the MSD service area consists of man-made facilities, structures,
and natural watercourses used for collecting and conducting stormwater to, through and from
drainage areas to the points of final outlet including, but not limited to, any and all of the
following: sewers, pipes, inlets, conduits and appurtenant features, canals, creeks, channels,
catch basins, ditches, streams, rivers, gulches, gullies, flumes, culverts, siphons, retention or
detention basins, dams, floodwalls, levees, and pumping stations (as defined by MSD Ordinance
14393). MSD maps the entire stormwater system using ESRI ArcMap GIS.
The source of GIS information comes from previously acquired sewer districts and as-built
surveys that are provided after the completion of development projects and capital
improvement projects. Updates are also made as a result of investigations by MSD Operations
and Engineering staff, as well as channel surveys completed under MSD’s Illicit Discharge
Detection and Elimination program.
• Prepare Field Gear
o Field screening tools
o Water sampling supplies
o Protective work clothing (MSD issued apparel, footwear, PPE, etc.)
o Communication equipment; Computer tablet and mobile phone with Man Down App
function correctly
o Miscellaneous tools (flashlight, machete, canteen, rope, bug spray, first aid, magnet,
etc.)
o MSD issued vehicle with routine stocked equipment, including manhole hook, dye,
brochures, door hangers, field NOV forms, etc.)
Customer Complaints (including response procedure)
• MSD Customer Care Division Questions for Customer:
o Obtain customer’s name, address and contact information including alternate contact
numbers or email address.
o Determine the location of the problem.
o Determine if the vehicle is marked with information such as a company’s name.
o Determine if customer knows the origin of the debris.
• MSD Customer Care Division Maximo Field Details:
o Create a service request in Maximo and complete all necessary fields.
o Assign a classification and priority code as applicable to the service request.
Classification and Code Assignment Examples:
1. Problem: Someone is currently dumping debris in the creek or on the bank.
Priority Code and Response time: Code 9, 4 hours
2. Problem: Someone is dumping or has dumped chemicals or oil into a creek.
Priority Code and Response time: Code 9, 4 hours
3. Problem: Someone has dumped debris in the creek or on the banks, no
environmental/safety threat.
Priority Code and Response time: Code 6, 5 days
o Enter detailed information from the customer and location of the problem in the details
field of the service request.
o If an alternate priority code is used, include a justification in the long description of the
service request.
o Create a work order for the DEC Standby person.
• MSD DEC Responsibilities:
o The investigation work order shall be assigned to DEC Standby as the owner.
o Remedial work will be performed by the party that has been dumping.
• MSD DEC Response Procedure:
o Upon arrival, the inspector shall locate the problem area and determine the extent of
the clean-up.
o Contact the municipality or St. Louis County and notify them of the situation (if
required).
o If warrant, notify the local police department.
o Complete the work order(s) and resolve the service request(s) in Maximo.
Follow-up with the customer to communicate findings.
Identify the findings and inform the customer of the action taken.
Notify the customer of any follow up actions by MSD.
Leave a Door tag and note tag number on the associated work order.

Illicit Discharge Field Investigation
This section will identify the steps to investigate pollution sources, to identify illicit discharges, and to
respond to illicit discharges so that appropriate corrective action or enforcement actions are taken.
Should any emergency assistance be needed in taking corrective action(s) please contact MSD 24-hour
service at (314) 768-6260. Refer to following Dry Weather Field Screening section and Enforcement
Response Plan section for specific details and actions.
• Follow MSD general safety procedures regarding monitoring weather, flash flood warning, and
mobile phone Man Down App.
• Stay out of culverts and structures unless confined space entry training has been completed and
corresponding procedures are used.
• Walk the stream in the channel in dry weather and inspect structures, outfalls, and channel
characteristics.
• If hazardous discharges or other discharges are encountered that could affect health and
safety, evacuate the area, and immediately notify emergency response agencies. Maintain a
safe distance from the area.
• Observe all dry weather flows from outfalls, ditches and small unmapped tributaries for
potential illicit discharges and evaluate physical characteristics.
• Observe and evaluate inaccessible outfalls (under water) from the structure or manhole nearest
the outfall or note that they could not be inspected.
• Identify wastewater, stormwater, or other infrastructure problems, and maintenance needs.
• Identify areas impacted by construction and land disturbance.
• Trace polluted discharges upstream in the drainage system by inspecting or sampling manholes
using visible indicators where possible. Collect grab or auto samples at various locations in the
system for laboratory analysis, as necessary, to identify unobservable pollutants or intermittent
discharges. Use field screening analysis to the degree possible to trace the discharge. Submit
samples for laboratory analysis, as necessary for confirmation and analysis of additional
pollutants (see following Dry Weather Field Screening section).
• Survey the drainage area to list suspected sources, based on pollutants identified.
• Based on tracing the discharge and/or identifying suspected sources, inspect properties, identify
processes and waste streams, note storage areas, note housekeeping practices, and attempt to
confirm discharge. Interview owners and occupants. Use confirmatory techniques, as necessary,
to confirm connection to the storm sewer system using maps, flow monitoring, dye testing,
smoke testing, or TV inspection. Collect samples of discharges onsite, wherever possible, for
laboratory analysis.
• Identify candidate areas for public participation in clean-up activities.
• Mark areas requiring follow up work or investigation, unless location description or maps are
adequate.
• Verify accuracy of the MSD GIS mapping system. A common discrepancy we encounter is sewer
infrastructure constructed of a different material than what is actually listed in MSD’s mapping
system. An example is when an inspector finds an exposed ductile iron pipe segment spanning
an open stream channel which is actually mapped as being constructed of vitrified clay material.
To effectively address incorrectly or unmapped assets, determine which area of MSD Operations
the issue is located and contact an Area Engineer, who can arrange to investigate further if
needed:
o Sulphur/City Yard, 1900 Sulphur Ave, St. Louis, MO 63110
o Mintert/North Yard, 7500 Mintert Industrial Blvd. Ferguson, MO 63135
o Grand Glaize/South Yard, 1025 Grand Glaize Parkway, Valley Park, MO 63088
As needed, contact MSD/Market/Engineering/GIS and follow Maximo rules regarding Map
Updates. Refer to Appendix for a Maximo update work order example.
• Document actions taken, in GIS and Maximo as applicable. Cooperate with other divisions,
request a reply to all referrals, and follow up on referred work to document resolution of
pollution investigations and illicit connections for the Stormwater program. Track number of
pollution sources discovered and abated to evaluate program worth.
• Elimination of illicit discharge and enforcement of Ordinance provisions. Illicit discharges can
include commercial or industrial non-storm water discharges into the storm sewer system,
direct sanitary sewer connections to the storm system, failing septic tanks, or infiltrating
groundwater contaminated from buried waste or sanitary sewer requiring rehabilitation.
Dry Weather Field Screening
Dry-weather flows discharging from storm drainage systems can contribute significant pollutant loadings
to receiving waters. If these loadings are ignored (by only considering wet-weather stormwater runoff,
for example), little improvement in receiving water conditions may occur. Prolonged dry periods during
the nongrowing season with low groundwater levels are optimal conditions for performing surveys. In
general, channel surveys work should be conducted at least 48 hours after the last runoff-producing rain
event.
Illicit dry weather flows originate from many sources and no Illicit discharge investigation will be the
same as the prior investigation. The general blanket approach MSD implements when conducting dry
weather field screening includes accessing physical indicators and indicator monitoring.
Physical indicators of odor, color, turbidity, sheens, stains, vegetation, and floatables can detect the
most severe or obvious illicit discharges, without use of indicator monitoring.
• Odor - Odors are strong indicators of identifying illicit discharges. Odors arising from an outfall
or discharge may assist the screening in narrowing down the source of a potential illicit
discharge. Typical odors may include sewage, sulfur, rancid (sour), petroleum, and natural gas. If
an area has a detectable odor of sewage, petroleum products, or fuel, the discharge must be
investigated. If the discharge area has a musty, pungent, or rotten egg (sulfide) smell, the
discharge must be investigated.
• Color – The color of a discharge is an important indicator in determining the presence of an illicit
discharge. The presence or absence of natural or man-made substances may influence the color
of a discharge. If the discharge flow is black, blue, red, white, purple, orange, or yellow, it must
be investigated.
8
• Turbidity – Turbidity is used as a supplemental observation for the presence of an illicit
discharge. Turbidity is caused by suspended particles in the discharge and is usually classified
into three categories: clear, cloudy, and opaque. In order to make an observation on turbidity,
collect a sample of the water in a clear glass jar, hold against sunlight, and record the
observations. When a cloudy/opaque discharge is found, further investigation is encouraged.
Fine sediment causing turbidity may be indicative of construction site runoff problems.
• Floatables –Typical floatable observations may include petroleum sheens, sewage, plastics,
paper, suds, or paint. The presence of floatables will assist in determining the source of the
discharge or indicate if illegal dumping has occurred. If significant amounts of trash or human
debris are found, the discharge should be investigated to determine if illegal dumping is
occurring.
• Sheens – Hydrocarbons can appear on the surface of a discharge in various sheens. If an oil
sheen is present on the discharge flow, it must be investigated.
• Vegetation – The health of the vegetation is an excellent indicator for identifying potential illicit
discharges. Poor and over-flourishing vegetation could indicate the presence of elevated
pollutant loads in a discharge. Over-flourishing vegetation could be an indication that the
discharge contains nutrients or fertilizers, while poor vegetative conditions could indicate the
discharge contains toxic substances. Excessive algae, grass, or weed growth around the outfall
must be investigated. Dead or discolored or reduced growth must also be investigated.
• Stains – Unnatural stains can indicate the presence of an illicit discharge. Staining of black, blue,
red, white, purple, orange, or yellow around an area must be investigated.
• Winter and Ice. MSD continues surveys below the freezing point. As applicable, ice can be used
as a discharge indicator when ice forms and remains for weeks. Most liquid illicit discharges are
warm, and can indicate sewage or industrial discharge. Be aware groundwater is warm enough
to cause some melting at below freezing temperatures.
If a dry weather discharge cannot be classified by physical indicators, indicator monitoring will be
performed. Indicator monitoring is a strategy of sample collection and laboratory analysis to detect and
characterize illicit discharges. MSD’s indicator monitoring primarily utilizes a Hach field sampling device
and MSD in-house laboratory to measure samples and compare results with benchmark values. Typical
benchmark values shown in the following table are common indicators used in MS4s throughout the
country.
• Staff will follow MSD DEC laboratory procedures for collecting and transporting samples.
• Collect sample in 250ml HDPE bottle.
• Perform Hach device field testing, as appropriate, and compare results with benchmark values
in table below.
• If further analysis required, transport sample to lab as soon as possible
• Complete chain of custody (see Appendix), describing or otherwise note why sample was
collected
o Note sample acquisition time
o Include field screening parameters and results (if conducted)
o List additional parameters of analysis to be tested
o Reason for Sampling: Check for Sewage
o LIMS Project Code: SE
• Reviewing results

Priority Areas
MSD prioritizes illicit discharge areas based on historical IDDE findings, reviewing databases, and
location of impaired streams. MSD also prioritizes illicit discharges when addressing complaints.
Historical IDDE findings are reviewed after completing every round of surveying the MS4 Plan Area
under BMP number 30. A scoring system in an excel database, filed with the Stormwater Unit,
completes this process. The number of Illicit discharge findings, wastes findings, blockage findings, and
infrastructure findings are tabulated and rated to determine the order of streams to survey in the next
survey round. For example, a stream with the most illicit discharges will be rated higher and prioritized
to survey early in the next survey round.
MSD utilizes its ISDS locations and failing laterals locations. Starting in 2022, channel surveyors start to
document ISDS conditions on their field tablets. This information will be collected similarly to how the
other findings data are collected and will be used as part of scoring future stream surveys explained
above.
MSD applies SWMP BMP number 35 to target improperly managed yard waste and illegal
dumping/littering areas. The number of door hangers placed over a 5-year period are tabulated and
mapped in GIS. Highly dense areas are identified on the map. MSD notifies the co-permittees over
these dense areas, and encourages them to focus on education to eliminate the problem. MSD has
suggested co-permittees use newsletters, websites, educating neighborhood groups, posting signs, and
share MSD yard waste public service announcements. MSD addresses the dense areas though social
media facebook education postings.
MSD Operations assists DEC to identify potential sources of bacteria in TMDL watersheds. Visual
findings from Operations inspections include the location of direct connections into storm sewer mains,
inlets, and manholes. Where private connections are discovered, they are reported to DEC to
investigate for and identify sources of bacteria that feed into the private storm sewer connections.
Based on the findings of the investigations, appropriate action is taken to eliminate discovered sources
of bacteria associated with the connection. It is anticipated that visual storm sewer inspections will be
improved and refined over time, becoming more effective at identifying and eliminating bacteria and/or
other identified issues in the watershed.
MSD prioritizes illicit discharge incoming customer complaints according to the following MSD
Operations Department Customer Complaint Emergency Response Times Codes. MSD tracks and
records all incoming complaints in the Maximo asset management system.
Code 6 - 5 Day Response
Code 7 - Response Time < 48 hrs.
Code 8 - Response Time < 24 hrs.
Code 9 - Response Time < 4 hrs.
Code 10 - Emergency < 2 hrs.
Training
All MSD DEC Stormwater Unit staff assigned to channel surveys and complaint responses shall receive
the following training:
• One-time 40-hour hazardous waste and emergency response training
• Annual 8-hour hazardous waste and emergency response training
• Annual MSD Pollution Prevention training

Appendix
GIS and Maximo Procedures
The following sections describes procedures for using ArcMap, ArcPad, and Maximo for documenting
channels walked, findings, and follow-up work. The sections are broken down into covering ArcMap,
tablets, equipment general use, ArcPad/Collector, Maximo, equipment care, and contacts.
The following sections also include business rules when creating / formatting / inputting data into the
GIS.
Moving Around ArcMap and Setting up Maps for ArcPad Viewing
Symbology and Scaling
The left side window in ArcMap is called the table of contents window and the boxes checked are the
selected layers you will see in ArcMap (desktop map application) and ArcPad (“tablet” application).
The following symbols are used to identify findings:
Start Daily Mileage (green signal light)
Stop Daily Mileage (red signal light)
Potential Illicit Discharge (blue water drop)
Infrastructure and Erosion (purple broken pipe)
24
Waste and Blockage (yellow and black debris pile)
Individual sewage disposal system
Daily Distance (yellow line)

Scoring Sanitary Infrastructure Condition
I. Work Flow for Rating and Reporting Sanitary Sewer Condition
II. Scoring Sanitary Infrastructure Condition in Maximo
The scoring system for rating sanitary infrastructure condition uses a scale of 0-3. Each point on the
scale represents a grade of condition and response action. See Table 1 below.
Table 1. Infrastructure condition scoring system.
Scoring criteria is based on asset type, material, and the risk of failure. Higher scores represent a greater
risk of failure or potential problem. Findings scored a value of three (3) are immediately reported to
Metropolitan St. Louis Sewer District’s (MSD) Customer Service while in the field. Scoring scenarios are
shown in Table 2.
Table 2. Example infrastructure findings and their respective scores.
Score Potential Example (s)
0 Exposed pipe constructed of ductile iron and in good condition.
1 Large sewer mains constructed of reinforced concrete with only top arch exposed in
channel. Exposed pipes constructed of ductile iron with potential to fail (e.g. exposed
ductile iron pipe spanning channel with fallen tree). Exposed manhole vertical (constructed
of reinforced concrete, brick and mortar, or plaster) in good condition.
2 Exposed pipe constructed of reinforced concrete, vitrified clay, or polyvinylchloride.
Exposed ductile iron pipe with joints in poor condition. Exposed manhole vertical with
cracks, gaps and holes, or that is leaning. Exposed manhole vertical with exposed pipe at
base.
3 Manhole with missing cover. Degraded asset with immediate potential for leaks and
infiltration.
Note: Actively leaking sanitary sewers were not included in the scoring system since they are reported
and addressed as illicit discharges under the channel inspection program.
Score Condition Response
0 Good No Corrective Action
1 Fair No Corrective Action
2 Poor Corrective Action Required
3 Serious Immediate Corrective Action Required
III. Work Order Procedures for Scoring and Reporting Sanitary Infrastructure Findings
DEC Stormwater Program staff are required to complete Maximo work orders for sanitary
facilities discovered during MCM3 channel inspections. These work orders will be used to rate
the condition of found assets, schedule repairs, and help meet reporting requirements under
MSD’s Phase II Small Municipal Separate Storm Sewer Systems (MS4) permit. Work order
procedures are as follows.
1. Access production Maximo at www.maximo.com, and enter your user name and password.
2. Create a new work order for each finding. From your start center, select “New Work Order”.
(Remember to enter the new work order number in the Reference ID column of the
Infrastructure and Erosion attribute table in Esri ArcMap).
3. Classify the work order. On the work order tab, click the arrows for the Classification field, click
“Select Value” (the first option denoted with a magnifying lens), and from the classification
menu select “DECINSP:DEC INSPECTION SEWER FINDING/RATING.” Note, steps 3-12 will be

4. Enter the Asset ID. Click the arrows for the Asset field and click “Select Value”. Type the facility
ID in the description box and click the “Enter” button on the keyboard. Select the correct asset.
5. Enter the Work Type. Click the magnifying lens for the Work Type field, and select “Corrective
Maintenance” (CM) or “Preventative Maintenance” (PM), or simply enter “CM” or “PM” into the
field. Note, assets scored 0 or 1 should be categorized as a PM, whereas those scored 2 or 3
should be categorized as CM.
6. Enter the Work Priority. Click the magnifying lens to the Work Priority field and select the
appropriate value. Assets scored 0, 1, or 3 should be assigned a work priority value of 0. Assets
with a condition score of 2 will require inspection and or repair work, and should be assigned a
value of 4 (60 day response).
7. Per Maximo business rules, spatially enable the work order by selecting “Auto-Create WO
(Spatial)” from the action drop down menu. Click “OK”, when asked “Are you sure you want to
automatically create GIS features for the current record?”
8. Complete the work order Long Description for assets scored a value of 2. Select the notepad for
the work order description field and describe the asset problem and required work in the
available window. Long Description information is not needed when assets receive a score of 0,
1, or 3.
Note: Work summaries provided in the Long Description will carry over to escalated work
orders; however, they will not show up in the WEBI Report.

Broken and Repaired Private Lateral Sewer Connection
Below are pictures of a broken private lateral sewer connection. This finding was recorded on
November 5, 2014 and later confirmed through dye testing. The home owner was issued a NOV letter
and directed to the St. Louis County Lateral Repair Program. The homeowner submitted an application
for repair to St. Louis County, who shortly thereafter completed the repair using ductile iron pipe and
concrete protection near the banks. Pictures of repaired line below were taken February 20, 2015.
Boat Usage
Coldwater Creek includes several miles of unimproved deep
permanent stream flow segments, where the MSD DEC boat must
be used for channel surveys.
While the stream is floatable downstream of Old Halls Ferry Road
to Hwy 367, access is quite limited. Typically the banks are too
steep and hazardous, or possible point of entry is cut-off by private
property. It may be possible to float one additional reach during
low water, and that would be from Old Halls Ferry Road to the
Christian Embassy Church at 13775 Old Jamestown Road. The
access at the church’s parking lot should be inspected first.
If seasonal conditions happen to be wetter, consider floating all the way to the mouth. Downstream of
Highway 367, there is an abundance of rocky outcroppings and riffles that make a low water float
impractical. Should gage height be higher, it may be possible to survey this reach by boat. New points
of entry will need to be verified beforehand of course. Recommend taking a day to recon points of
access prior to next survey.
Mileage Notes
Dunn Road to Dierbergs = 1.54 mi
Dierbergs to St. Denis Street = 0.43 mi (poor point of entry at St. Denis Street)
St. Denis Street to New Halls Ferry Road = 2.38 mi

• Stabilization times with smaller concentration changes generally will be longer and can be minimized by
proper stirring and conditioning. Experiment to determine the proper stir rate if necessary
• The integrated temperature sensor and HQd meter software do not compensate for differences in
temperature between calibration standards and samples. Measurement stabilization is not dependent on
temperature stabilization. Temperatures of calibration standards and samples should be kept within ±2 °C
of each other for optimal results.
• Data is automatically stored in the data log when Press to Read or Interval is selected in the Measurement
Mode. When Continuous is selected, data will only be stored when Store is selected.
• Between measurements, rinse the probe with deionized water. Blot dry with a lint-free cloth. Do not touch
the tip of the probe.
• Air bubbles under the sensor tip when submerged can cause slow response or error in measurement. If
bubbles are present, gently shake the probe until bubbles are removed.

Interferences:
The sensing element responds to ammonia as well as other ions. Typically, probe response to another
ion increases the potential, and causes a positive error. The response to other ions can be semi-
quantitatively determined through the Nikolsky equation, an extended Nernst equation:
E = Eº + (RT/(zF))ln[aNa + KNax × ax] Where
• ax—the activity of the interfering ion
• KNax—the selectivity coefficient for the interfering ion relative to chloride
Volatile amines interfere with Ammonia ISE measurement. Most gases do not interfere as they are converted to
ionic form in basic solutions. Ionic species cannot cross the gas- permeable membrane and are not direct
electrode interferences. However, the level of ions in solution can change the solubility of ammonia. Standards
and samples should have about the same level of ions and dissolved species.
Ammonia forms metal complexes with a number of metal ions: mercury, silver, copper, gold, nickel, cobalt,
cadmium and zinc. At pH >11, most of these metals form hydroxide complexes or precipitate. The Ammonia ISA
adjusts the pH to >11. When hydroxide is present at the 0.1 M level and the ammonia concentration is below
10-3 M, only mercury will appreciably complex ammonia. The total ammonia level of the sample will be
measured if the mercury in the sample is preferentially bound to some other species.
Iodide is recommended for this purpose, since it forms a soluble mercury complex at all pH levels. Use of
Ammonia ISA inhibits the formation of some common metal complexes in the sample because it contains a high
concentration of hydroxide ion
Maintenance:
Clean the probe when:
• Drifting/inaccurate readings occur as a result of contamination on the sensing element or improper
storage conditions.
• Slow response time occurs as a result of contamination on the sensing element.
• The slope is out of range as a result of contamination on the sensing element.
For general contaminants, complete the following steps.
1. Rinse the probe with deionized water. Blot dry with a lint-free cloth. Do not touch the tip of the probe.
2. If harsh contaminants are attached to the probe, polish the probe tip with a soft cloth or cotton swab to
remove the contaminants.
3. Soak for 30 seconds in 25 mL of Ammonia probe storage solution
Storage:
Short term storage:
Put the probe with the attached membrane module in 25 mL of Ammonia probe storage solution. Do not let
the membrane dry out. A soaker bottle is not required.
Overnight and mid-term (up to one week) storage:
1. Put the Ammonia probe with the attached membrane module in 1000 mg/L Ammonia standard solution
without Ionic Strength Adjustor (ISA). Do not let the membrane dry out. A soaker bottle is not required.
2. Put a cover over the storage beaker and probe body to prevent solution evaporation.
Long-term (more than one week) storage:
1. Remove the Ammonia membrane module from the probe body.
2. Rinse the probe and membrane module with deionized water. Blot dry with a lint-free cloth. Do not
touch the tip of the probe. Do not rub the membrane surface.
3. Install the protector cap over the membrane module and put the Ammonia membrane module in a
protected area. The disassembled membrane module can be allowed to dry.
4. Fill the probe soaker bottle halfway with Ammonia probe storage solution.
5. Install the probe soaker bottle. Make sure the storage solution in the cap completely surrounds the
glass bulb
*Note: After long-term storage, the probe (with membrane module assembled) might need to be conditioned in
Ammonia probe storage solution for up to 30 minutes to improve the stabilization speed

Preparation for use:
Prepare the probe for use before calibration or sample measurement.
1. Remove the sensor protection cap from the probe.
2. Rinse the probe with deionized water. Blot dry with a lint-free cloth.
*Note: Prior to use, the probe must be conditioned for at least 30 minutes in 25 mL of the lowest concentration standard solution in the
calibration set. If probe stabilization is slow after storage, condition the probe for up to one hour in 25 mL of the lowest concentration standard
solution in the calibration set
Calibration:
Calibration notes:
• Stir the standards and samples at a slow and steady rate to prevent the formation of a vortex.
• Additional standard sets along with the minimum number of calibration points can be selected on the Calibration Options menu.
• Push Skip to omit a standard from the calibration routine. The display will not show Skip until the minimum number of standards is
met.
• Begin with the lowest concentration during calibration. This reduces carry-over contamination to give the best results.
• Note the temperatures of the standards during calibration. Keep temperatures between calibration standards within ±2 ºC for optimal
results.
• The calibration is recorded in the electrode and the data log.
• Air bubbles under the sensor tip when submerged can cause slow response or error in measurement. If bubbles are present, gently
shake the probe until bubbles are removed.
Calibration Procedure:
1. Connect the probe to the meter. Make sure that the cable locking nut is securely connected to the meter. Turn the meter on
2. In three separate beakers or appropriate containers, prepare Chloride standard solutions (minimum 25 mL volume).
3. Add the contents of one Chloride ionic strength adjustment (ISA) powder pillow per 25 mL to each standard
4. Push Calibrate. The display shows the current standard value that is to be read from the standard solution set.
5. Rinse the probe with deionized water. Blot dry with a lint- free cloth
6. Add a stir bar and put the probe in the first standard solution in the set. Do not put the probe on the bottom or sides of the container.
7. . Put the beaker on an electromagnetic stirrer and stir at a moderate rate. Check for air bubbles and remove them if
necessary
8. Push Read. The display will highlight the standard value and proceed to the next standard value. The display will show "Stabilizing" and
a progress bar as the reading stabilizes. The display shows the standard value when the reading is stable.
9. Repeat steps 5-8 for the other Chloride standard solutions in the set.
10. Push Done to view the calibration summary. The display will not show Done until the minimum number of calibration points have been
collected.
11. Push Store to accept the calibration and return to the measurement mode.
Measurement:
Measurement notes:
• Stir the standards and samples at a slow and steady rate to prevent the formation of a vortex.
• Stabilization times with smaller concentration changes generally will be longer and can be minimized by proper stirring and
conditioning. Experiment to determine the proper stir rate if necessary.
• The integrated temperature sensor and HQd meter software do not compensate for differences in temperature between calibration
standards and samples. Measurement stabilization is not dependent on temperature stabilization. Temperatures of calibration standards
and samples should be kept within ±2 °C of each other for optimal results.
• Data is automatically stored in the data log when Press to Read or Interval is selected in the Measurement Mode. When Continuous is
selected, data will only be stored when Store is selected.
• Between measurements, rinse the probe with deionized water. Blot dry with a lint-free cloth.
• Air bubbles under the sensor tip when submerged can cause slow response or error in measurement. If bubbles are present, gently
shake the probe until bubbles are removed.
Measurement Procuedure:
1. Prepare a minimum of 25 mL of the sample(s) in beakers or appropriate containers. Add the contents of one Chloride ionic strength
adjustment (ISA) powder pillow per 25 mL to each sample.
2. Rinse the probe with deionized water. Blot dry with a lint- free cloth.
3. Add a stir bar and put the probe in the sample. Do not put the probe on the bottom or sides of the container.
4. Put the beaker on an electromagnetic stirrer and stir at a moderate rate. Check for air bubbles and remove them if necessary.
5. Push Read. The display will show "Stabilizing" and a progress bar as the probe stabilizes in the sample. The display will show the lock
icon when the reading stabilizes.
6. Repeat steps 2- 6 for additional measurements
7. When measurements are done, store the probe.
Interferences:
The sensing element responds to chloride as well as other ions. Typically, probe response to another ion increases the potential, and causes a
positive error. The response to other ions can be semi-quantitatively determined through the Nikolsky equation, an extended Nernst equation:
E = Eº + (RT/(zF))ln[aNa + KNax × ax] Where
• ax—the activity of the interfering ion
• KNax—the selectivity coefficient for the interfering ion relative to chloride
• High levels of ions which form insoluble salts of silver can deposit a layer of salt on the sensing surface, and cause electrode
malfunction. Strong reducing solutions can also form a surface layer of silver. In either case, clean the sensing element. Refer to
Clean the probe on page 10.
• Mercury must be absent from samples.
• Measurements can be made in solutions that contain oxidizing agents such as Copper (Cu2+), Iron (ferrous) (Fe3+) and Maganate
(MnO -).
• If Chloride ISA is added to the standards and samples, the effect of interfering ions is minimized.
Maintenance:
Clean the probe when:
• Drifting/inaccurate readings occur as a result of contamination on the sensing element or improper storage conditions.
• Slow response time occurs as a result of contamination on the sensing element.
• The slope is out of range as a result of contamination on the sensing element.
For general contaminants, complete the following steps.
1. Rinse the probe with deionized water. Blot dry with a lint-free cloth.
2. If harsh contaminants are attached to the probe, polish the probe tip with a soft cloth or cotton swab to remove the contaminants.
3. Soak for 30 minutes in 100 mg/L Chloride standard solution.
Storage:
The probe can be stored dry. To protect the sensing element, rinse with DI water and blot dry with a lint-free cloth. Install the sensor protection
cap.
*Note: The probe must be conditioned after long-term storage. Refer to Preparation for use
