SECTION 1 - INTRODUCTION
This Section describes, the site entry. authotfty, purpose of the inspection, and the system.
Site Entry and inspection Objectives
EPA inspectors arrived at Cahokia Heights Public Water System (the "System''), bested at 2525 fvlousette
Lane. Cahokie Heights, Illinois 62206, at Si30 AM on October 18. 2022. for an announced inspection. James
Adamiec presented o edentiats to System representatives, Dennis Traiteur and Sharim Pfeffer and informed
them that this was a Region 5 inspection to determine compliance with the Primacy Agency requirements and
the Safe Drinking Water Act (SDWA). The inspection was conducted under the authority of the SDWA Section
1445. This report is based on information supplied by Cabokia Heights (©preventatives, cbsetvatons made by
the Region 5 inspectoral, and records and reports maintained by the System and Region 5 including; direct
observations made by the Region 5 mspector(s), phetograpns taken by Pegion 5 inspectoral, physical
evidence collected by the Region 5 inspectors), measurements taken by Region 5 inspectors), verbal or
written statements made by information supplied by Cahekio Heights representatives during or subsequent to
the on-site inspection, and materials, processes, data, photographs, cr documents shown, demonstrated, ot
submitted to the Region 5 inspector(s') by Cahokia Heights representatives ciui ing ot subsequent to the on-site
Inspection, In addition, information gathered prior to or subsequent to the Inspection from a rev ew of U3EPA,
State, and public records may be included in this report.
The scope of the inspection was an onsite review of the water source, facilities, equipment, operation,
maintenance, and monito< ing compliance of a public water supply iFWS) to evaluate the adequacy of the
FWS, its sources and operations, and the distribution of safe drinking vvater. The inspection was focused on
>rei ikying compliance with the SDWA Section 1431 Unilateral Administrative Order, dated August 2, 2021 (the
System Description
The ihinois Env'uonmental Ptotection Agency maintains the Drinking Water Watch >,vebs!te wh.ch provides e
recotct ot the System's owner, operator, and Siie. According to Illinois Dm!- ing Water Watch, the System is
owned bv the City of Cahokia Heights, serves a population of approximately 13.SCS peop'e and has 5,600
2
-------
service connections. It is a community water system as defined by 40 C.F.R., Part 141 Subpart A. EPA did not
confirm the information from Drinking Water Watch with the System.
The system is a consecutive system that purchases finished surface water directly from Illinois American - East
St. Louis (PWSID IL1635040). The System is a municipality serving both business and residential customers
including schools. The System employs one certified drinking water operator, Dennis Traiteur, and has two
additional operators in training.
System Information
System information was collected through a records review or statements made by System representatives
during the inspection. This information is organized into discussion topics and the topics are designated with a
reference number. Each entry then indicates whether the discussion topic is an Area of Concern (AOC). AOCs
are further discussed in Section V.
Reference #: IN-001
Topic: Staffing
In May 2021, several smaller communities merged to become the City of Cahokia Heights, which then
became its own PWS. During the reorganization period, drinking water staffing levels were adjusted to
eight designated drinking water staff. This includes a field director and certified water operator plus seven
maintenance staff. Two of those maintenance staff are in training to become certified water operators.
The System reported that they will be taking a certification test in December 2022.
Reference #: IN-002
Topic: EPA Compliance Advisor
AOC: No
EPA offers a compliance advisor program where technical staff visit a system and can offer expertise in
developing SOPs, training documents, report templates, and public outreach. A compliance advisor team
provided an in-person consultation for the System in mid-2022 and continues to provide ongoing assistance
remotely. Most recently, the advisor team assisted the system with developing a staffing recommendation
and a nitrification action plan in August 2022.
Reference #: IN-003
Topic: ICR Monitoring
AOC: No
The System conducts monitoring for compliance with the lead and copper rule every six months at 60 sites.
While the system does not have a history of lead or copper violations, it also lacks a completed lead service
line inventory. The System is in the process of compiling an inventory and has contacted customers with
questionnaires about the plumbing in their homes. To date, the customer response rate has been low at
roughly 12%. From those responses, no lead service lines have been identified. For residents that have not
responded to the questionnaire, System staff plan to go door to door to try to get responses. During the
inspection, the System was unable to project when a complete lead service line inventory would be
available because it is so dependent on customers. 40 CFR 141.84(a)(1) requires an initial inventory to be
developed and submitted to the primacy agency by October 16, 2024.
Reference #: IN-004
Topic: O&M - Flushing
AOC: No
3
-------
In coordination with their upstream water provider, Illinois American - East St. Louis, the System conducted
city wide flushing in June and August 2022. The exact dates for flushing vary year to year depending on
river conditions of the source water. The flushing this year coincided with Illinois American - East St. Louis's
treatment switch from chloramines to free chlorine at that time. The UAO cited a failure to conduct system
wide flushing as a significant deficiency. The System now reports that they have worked to further develop
this program to address that significant deficiency.
Topic: Monitoring
Since the UAO was issued in August 2021, the System added four additional bacterial sampling stations to
their state approved RTCR Sample Site Plan. These additional locations are sampled on a routine monthly
basis and after each sanitary sewer overflow. The System has also installed continuous pressure monitors
at four locations in Cahokia Heights.
Topic: O&M - Treatment
The System purchases finished water from Illinois American - East St. Louis. Illinois American - East St. Louis
uses chloramines as a disinfectant while the Cahokia Heights public water system's only treatment includes
the addition of booster chlorine at the Springs booster station. The System adds booster Chlorine as
a disinfectant during the summer months, typically June-September and System staff stated it was
necessary to add in order to maintain a chlorine residual in the furthest ends of their system. To add this
booster chlorine, the chlorine feed rate is automatically adjusted based on chlorine readings taken at the
feed site using a digital analyzer. The digital analyzer does not monitor ammonia levels. The System does
not currently have the capability to also add ammonia (chloramines). Improvements to the disinfection
system, including upgrades to allow for treatment with chloramines, are included in CH's Capital
Improvement Plan (the CIP), dated November 5, 2021. As of the inspection date, a contracted engineering
group has begun work on design plans for the disinfection system upgrade. However, the System is unable
to estimate when actual construction may take place and continues to add chlorine only, without ammonia.
Topic: Storage
The System has three storage tanks. The condition of the tanks, such as rust or inability to fill, was noted as
a significant deficiency in the UAO:
1. Springs tank: This is a ground level tank that has not been in service for at least 20 years. An
active chlorine booster station for chlorine is located at this site. Prior to returning the tank to
service, it would likely need extensive repairs. System representatives stated that the tank will
either be rehabbed or rebuilt in order to increase their storage capacity, however, this is not a
priority issue for them. As of the inspection date, the System is unable to estimate when such
repairs would take place.
2. Road tank: The tank is an elevated water tank that the System has been unable to
completely fill since 2000 when a pump broke. This tank had an exterior inspection in late 2021.
Following that inspection, some repairs were completed in November 2021. The tank interior was
then inspected in December 2021. The System is planning a full rehab of the tank and expects this
to be completed sometime 2023.

3, Mullens tank This is an elevated storage tank that had an interior and exterior inspection in
late 2021. An inspection repott was issued on October 15, 2021. Following the inspection report,
some repairs were made frcm March - May 2022 to address critical issues. Additional repairs are
awaiting funding and these is no definitive projection on when these might be completed.
