Barbara Featherson, Tyler Lollis, and Derek Delo from LDH also attended the inspection. Fatima Shaikh and Heidi Rausch presented their credentials to the system representatives and informed them that this was an EPA inspection to evaluate the system under the SDWA. Additionally, the inspectors evaluated the Risk and Resilience Assessment (RRA), Emergency Response Plan (ERP), and cybersecurity practices under the SDWA Section 1433(a) and (b), which require community water systems that serve more than 3,300 people to develop and certify completion of an RRA and ERP. This report summarizes observations made during the inspection, which consisted of the following activities: Site visits to the System's WTP: o Surface Water Intake o Nine (9) aerators o Flocculators o Sedimentation Basins o Six (6) filters o Aluminum Sulfate (alum) Room o Chlorine Room o Ammonia Room o High service pumps o Ground storage tanks o Elevated storage tanks Evaluation of RRA, ERP, and Cybersecurity, and other system records Photos taken during the inspection are located in Appendix 2. 2 FACILITY DESCRIPTION City of Monroe PWS ID#: LA1073031 Inspection Date: 05/07/2025 The City of Monroe Public Water System (PWS) is a community water system located in Tallulah, Madison Parish, Louisiana. The City PWS has 19,000 service connections and serves a population of 57,000 customers, according to Louisiana Department of Health Drinking Water Viewer database. The water system is a surface water system with water supply coming from Bayou Desiard and the Ouachita River. The plant consists of conventional treatment including aerators, flocculators, sedimentation, filters, chlorination, ammonia feed, alum feed, pumps, and storage tanks. There are eight operators at the plant. The plant operates on 12-hours shifts from 6 am to 6 pm, with two operators per shift. The supervisor is also at the plant during normal business hours. LDH conducted sanitary surveys of the system in 2021 and 2023 and identified a few deficiencies, which were resolved after the surveys. Section II INSPECTION ACTIVITY SUMMARY The EPA Inspection Team conducted field activities and interviews to observe the PWS operations and understand the WTP process and condition of the system assets. The LDH sanitary survey reports were provided prior to the inspection to help the inspection team gain a general understanding of the PWS and its compliance. The information in this report is based on document reviews, conversations with the system representatives and LDH, and observations made during the inspection. The documents provided for review by the PWS before and during the inspection included: Cross Connection Control Program Customer Complaints Log Tank Inspection Reports Tank Cleaning Schedule for all tanks within the next five years Water Letter Grade Asset Management Plan and Inventory Work Order Program Safety Data Sheets for chemicals Risk and Resilience Assessment Emergency Response Plan Previous Sanitary Surveys The EPA Inspection Team reviewed the most recent sanitary survey conducted by LDH, which took place on November 14, 2023. This survey identified three significant deficiencies. The deficiencies from 2023 sanitary survey are listed in Table 1 below. 3 City of Monroe PWS ID#: LA1073031 Inspection Date: 05/07/2025 Table 1 Date First Observed 11.14.2023 Significant Deficiency The water system did not provide documentation of a complete list of customers required to install backflow prevention devices and a record of annual testing for each device. Summary of Current Status The cross-connection control program with the backflow prevention test letters was observed. 11.14.2023 At the Ruffin Drive booster station, a moderate amount of erosion had occurred on the southeast section of the site underneath the fencing, compromising the functionality of the fencing. The fencing concerns were discussed during the inspection with LDH, as the system representatives plan to address the deficiency. 11.14.2023 At the Thomas Street booster station, one of the pumps had a small leak from the pump packing. The leak was not observed at the time of the inspection. FACILITY/SYSTEM WALKTHROUGH Monroe Water Treatment Plant The walkthrough of the WTP began at the filters. There were six filters, all of which were operational. Four of the filters were old and had been rehabbed within the last six years. The rehab of the filters included the addition of new media (anthracite and sand) and air scour. Core sampling is done to inspect filter media, and the filters are cleaned every few years. Two filters were new. The system representatives noted that the raw turbidity from the source water was 1.5 NTU, increasing to 3 NTU during heavy rain. The highest turbidity observed was 5 NTU. It was mentioned that the Bayou was the main raw water supply, while the river was only used during drought season when the Bayou levels were low. The filters operated on automatic backwashing, dictated by the run time (every 72 hours) and turbidity. The backwash process was visually monitored by an operator; therefore 80% of the process is automated. The operator hoses down the filters to remove the algae. The backwash water goes to the sewer and out to the river. Next, the aerators were observed. There were nine aerators, all in operation. The purpose of the aerators was to remove organic gas for taste and odor control. Chloramine, aluminum sulfate, potassium permanganate, and activated carbon are all fed at the aerators. Additionally, bands were added to the aerators to reduce splashing. The system representatives mentioned that there was a golf course next to the WTP which required screens (Photo 1) to be put up to prevent golf balls from impacting the equipment. 4 City of Monroe PWS ID#: LA1073031 Inspection Date: 05/07/2025 Following the aerators, the potassium permanganate room was observed. There were four chemical feed pumps: three were used for the mixing channel, and one was a spare. An eyewash station was observed. The bulk caustic tanks were observed outside in secondary containment. Next, the alum room was observed. There were three aluminum sulfate fiberglass tanks. The dosage of the alum is dictated by the flow and is approximately 10-11 ppm. There were three chemical pumps pumping to the static mixers and one backup pump. A zinc orthophosphate tank, which is also used for corrosion control, was observed. There are two chemical pumps that pump to the high service pumps at the end of the process for zinc orthophosphate addition. The ammonia room was observed with five ammoniator machines. They were labeled with the injection sites going to high service pumps and train. An eyewash station was also observed. Next, the chlorine room was observed. There were 24 one-ton chlorine gas cylinder tanks. Chlorine analyzers and vents were observed. According to the system representatives, deliveries of the chlorine gas are made approximately every 2-3 months. Outside, a bulk activated carbon tank, and two ammonia tanks were observed. Next, the walking beam flocculators were observed, following the sedimentation basin. For the sludge, there is an underwater rake system. The sludge from the basin goes to the river through a permitted outfall. There was discussion of a possible sludge treatment system with a sludge lagoon in the future. The system representatives stated that there is a preventative maintenance (PM) program. The basins are taken offline every three months for washing and clearing, with one basin cleaned at a time. Following the sedimentation basin, the lab was observed. There are four lab staff: two work in-house, one is on rotation, and one conducts field sampling. Grab samples are taken from each process every hour including measurements for chlorine, alkalinity, pH, odor, hardness, color, iron, and manganese. All of the equipment is calibrated. The raw turbidity was observed to be 1.49 NTU on the turbidimeter. The system representative mentioned that the target chlorine residual in the distribution system was 2-2.3 ppm in the summer and 1.5-2.3 ppm in the winter. The pH target was 8-8.5. Jar testing was conducted for making changed in coagulation and optimizing the process. The engineer came in to perform changes in injection points, re-rating of the current plant, and conducted a tracer study. Next, the four high service pumps were observed. Two pumps are used at a time. The pump with the highest rating pumps about 12 MGD. The largest pump is usually utilized during a high usage event such as a fire. There were two ground storage tanks onsite at the WTP. The 3.1 MG tank was inspected in 2023, and the 3.3 MG tank was inspected in 2024. The tanks are connected and operate in parallel. They are used for contact time and are baffled. The tanks combine to one overflow which is flapped. Chlorine is injected in the 30-inch transfer line. System representative stated that the valve exercising program started a month prior to the inspection and was in progress. Every valve in the city was mapped and is included in the city's Geological Information System (GIS), including the hydrants. 5 City of Monroe PWS ID#: LA1073031 Inspection Date: 05/07/2025 The assets observed below were all located offsite. Chauvin Tank Pump Station The Chauvin Tank has a capacity of one MG and was built in 2018 for expansion. The overflow of the tank was observed to have a flap that flows out to the bayou. The tank was inspected in 2023. The total chlorine reading was observed to be 1.85 mg/L on the chlorine analyzer in the pump station. The station has its own generator. Ruffin Tank Booster Station At the Ruffin tank booster station, two pumps were observed. There was boosting of chlorine and ammonia at the station. The reading in the chlorine analyzer was 2.36 ppm. The turbidity reading was 0.223 NTU, and the pH was 7.21. Chlorine alarms, detectors, crash bar door, and vent fan were observed. The pump station has its own generator. The Chauvin tank has a capacity of 3.1 MG. Vegetation was observed next to the fencing, with a tree above the fencing. The system representative discussed that the tank was inspected in 2022, during which thin areas observed on the tank. About 2-3 inches of sediment was removed at the time of the tank inspection. The tank is scheduled to be rehabilitated. Thomas Tank Booster Station The Thomas tank is a 1.5 MG tank that was built in 1950. The overflow was screened and discharged into the storm drain. According to the system representatives, the tank was last inspected three years ago. It was observed that the pH at the station was 7.86, the turbidity was 0.151 NTU, and the chlorine residual was 2.18 ppm. A room containing liquid aluminum sulfate was observed, as well as a chlorine room with a chlorine detector, ventilation, chained cylinder gas tanks, and an entry door with a knob. Selman Pump Station Next, the Selman pump station was observed with three pumps. The pH was observed to be 6.99, the turbidity was 0.219 NTU, and the chlorine residual was 1.85 ppm on the chlorine analyzer. According to the system representatives, the pH was lower at this station due to adjustments to the chlorine feed. In the chlorine room, it was observed that cylinder gas tanks were chained, the chlorine detector was visible. Next, the Selman tank was observed, which is a 4 MG concrete tank. The overflow was flapped and screened. Powell Elevated Storage Tank The Powell tank was observed. It was 135 feet tall, with a capacity of 500,000 gallons, and was built in 1953. It was observed that the turbidity was 0.121 NTU, the pH was 8.35, and the chlorine residual was 1.85 ppm. 6 City of Monroe PWS ID#: LA1073031 Inspection Date: 05/07/2025 Grammont Tower Next, the Grammont tower was observed. Its capacity is 500,000 gallons, and its height is 115 feet. The overflow was flapped and screened. The chlorine residual was observed to be 1.87 ppm, the pH was 8.51, and the turbidity was 0.107 NTU. Bayou Intake Next, we observed the bayou intake, which had three pumps. Pump 1 had a capacity of 7 MGD, Pump 2 had a capacity of 12 MGD, and Pump 3 had a capacity of 7 MGD. System representatives mentioned that raw water testing was completed everyday, including measurements for turbidity, alkalinity, and pH. It was also discussed that there were bar screens at the intake. If leaves get stuck on the screen, the pumps are shut down to remove the debris. The indicator for debris being stuck on the screen is that the pumps usually struggle to work. The intake was at a depth of 65 feet, and there were cameras installed.
