Payne, Secretary 1027 W. St. Paul Avenue Telephone 608-266-2621 Milwaukee, WI 53233 Toll Free 1-888-936-7463 TTY Access via relay - 711 January 5, 2023 Jennifer Pankowski, Clerk PWSID#: 25202023 Village of Waterford Region: Southeast 123 N. River St. County: Racine Waterford, WI 53185 Subject: WI-DNR Sanitary Survey Report and Notice of Noncompliance Dear Ms. Pankowski, The purpose of a Sanitary Survey is to evaluate the system’s source, facilities, equipment, operation, maintenance, and management as they relate to providing safe drinking water. The sanitary survey is also an opportunity to update the department’s records, provide technical assistance, and identify potential risks that may adversely impact drinking water quality. This Sanitary Survey Report also serves as a Notice of Noncompliance. On December 13, 2022, Christopher Durgin conducted a sanitary survey of your water system, Waterford Waterworks. During the sanitary survey Rick Huening, Utility Supervisor, was also present. At the completion of the survey, Mr. Huening was briefed on the preliminary findings. This report outlines the final findings, discusses problems that need to be addressed, and timelines for corrective action where appropriate. Required action A response to this report and a plan for corrective action must be received by the department by February 17, 2023. The response shall include a notification that all deficiencies have been corrected, that you agree to correct the deficiencies identified in this letter by the due dates, or with proposed alternative dates for correcting these deficiencies. A corrective action plan and schedule is included below for your consideration. Depending on the type of corrective action you employ, you may need to obtain prior approval and submit additional plans to the department. dnr.wi.gov wisconsin.gov  17 Significant Deficiencies During the course of the sanitary survey, no (0) significant deficiencies were identified. Significant deficiencies indicate noncompliance with one or more Wisconsin Administrative Codes and/or represent an immediate health risk to consumers. As such, the deficiencies listed below should be corrected as soon as possible. All codes cited are from s. NR, Wis. Adm. Code. Deficiencies During the course of the sanitary survey, Five (5) deficiencies were identified. Deficiencies are problems in drinking water systems that have the potential to cause serious health risks or represent long-term health risks to consumers. These deficiencies indicate noncompliance with one or more Wisconsin Administrative Codes. Corrective action should be completed for these deficiencies as soon as practical. A more detailed explanation is provided later in the report. All codes cited are from s. NR, Wis. Adm. Code. Code Compliance Deficiency Brief Description of Deficiency Required Corrective Action Violation(s) Due Date 1. Chemical Storage must have secondary containment 811.39(3)(d) 2/17/2023 2. Air releases must be downward facing with 24 mesh screen 811.37(5)(a) 2/17/2023 3. Vents must be downward facing with 24 mesh screen 811.36(1)(a) 2/17/2023 4. Elevated storage overflow lacking adequate 4 mesh screen 811.64(4)(c) 2/17/2023 5. Valves are not being exercised at an adequate frequency 810.13(2)(a) 2/17/2023 Recommendations During the sanitary survey, Twelve (12) recommendations were identified. Recommendations are problems in the water system that hinder your public water system from consistently providing safe drinking water to consumers. Recommendations 1 Add labels to sample taps to clarify where samples should be taken 2 Eliminate dead ends by looping mains when feasible 3 Check all anti-siphon devices to ensure functionality 4 Continue to monitor screens covering chemical vents, air vents and overflows 5 Periodically review records of complaints for reoccurring problems 6 Complete comprehensive water system studies 7 Plan for the retirement of experienced staff 8 Conduct emergency “table-top” exercises to practice emergency situations 9 Acquire standards for colorimeter calibration. 10 Confirm that your system is taking adequate measures to protect against cybersecurity threats 11 System should consider a leak detection study due to water loss exceeding 10% 12 Replace undersized mains (4 inch) with more adequately sized mains to allow for greater fire flow Waterford Waterworks Sanitary Survey Report Page 2 of 15  18 Non-Conforming Features During the course of the sanitary survey, two (2) Non-conforming features were discovered. “Non-conforming features” (NCF) are areas that met code requirements at the time of your public water system’s construction but would not be allowed in the current code. Though you are not required to correct these non-conforming features at this time, they will need to be corrected when a public health risk exists (water-borne illness, water quality complaints, positive bacteria sampling, cross connections and potential for contamination can all be considered when determining public health risk) or it falls within a reviewable project in the future (new water main construction or pipe relay in the area reviewed under chs. NR 811 or DSPS 382, Wis. Adm. Code) per s. NR 811.01, Wis. Adm. Code. This list may not be inclusive of all existing non-conforming features of your water system. When conducting significant upgrades on your facility or pieces of equipment, it is recommended that you contact your DNR representative to aid you in identifying such features. All codes cited are from s. NR, Wis. Adm. Code. Feature Location Brief Description Code Violation(s) Chemical 1 Chemical injectors are not located on the bottom half of the pipe 811.39(7)(f) injectors 2 Well 4 and 5 Sample taps are not downstream of check valves 811.37(5)(b)(1) Discussion and Schedule for Corrective actions The discussion section of the paper provides a more in-depth explanation of the deficiency or recommendation, the risk it poses to your system, and how completing the corrective action benefits you and your customers. If pictures were taken during the survey, they will be located in either the discussion or at the end of this report in the appendix. Deficiencies 1. S. NR 811.39(3)(d), Wis. Adm. Code requires Chemical feed equipment… “Be located within a containment basin capable of receiving accidental spills, drainage, or overflows without an uncontrolled discharge outside of the containment basin.” … • By February 17, 2023, please install adequate containment or curbing for all chemical feed containers. • Note: Chemical containment basins shall be sized to contain the volume of the largest tank that could fail. Waterford Waterworks Sanitary Survey Report Page 3 of 15  19 Figure 1 and 2: Chemical storage without secondary containment 2. S. NR 811.37(5)(a), Wis. Adm. Code requires “For line-shaft vertical turbine pump discharge pipes, an air- vacuum relief valve shall be installed between the pump and the check valve. The discharge line from the relief valve shall face downward and terminate with a 24-mesh corrosion resistant screen, at least 24 inches above the floor.” • By February 17, 2023, please install adequate air release vent screening at well 1 Figure 3: Well vent not downward facing Waterford Waterworks Sanitary Survey Report Page 4 of 15  20 3. S. NR 811.36(1)(a), Wis. Adm. Code requires “For wells without pitless units, a metal vent pipe shall be installed which terminates in a 24−mesh corrosion resistant screened “U” bend or mushroom cap at least 24 inches above the floor. • By February 17, 2023, please install adequate well vent screening at well 5 and its associated booster pumps 4. S. NR 811.64(4)(c), Wis. Adm. Code requires “The overflow pipe shall be provided with a 4-mesh corrosion resistant screen installed within the pipe at a location least susceptible to damage by vandalism.” • February 17, 2023, please install adequate overflow screening at Tower 1 • Note: Please clear the excess brush away from the overflow area Figure 4: Tower 1 Lacking adequate 4 mesh screen 5. S. NR 810.13(2)(a), Wis. Adm. Code requires “All distribution system valves shall be exercised a minimum of every 2 to 5 years.” • By February 17, 2023, please submit a plan or schedule to complete valve exercising by 2028 Recommendations: 1. Labeling sample taps is a cheap and simple way to avoid miscommunication on where samples must be taken. By including labels on all taps, the chances of samples being incorrectly taken is greatly decreased. 2. The department recommends that the Utility continue to eliminate dead end mains where feasible. Looping mains can increase water quality, decrease maintenance, and reduce the number of homes affected by a water main break. 3. Over time, anti-siphon devices on peristaltic chemical pumps can corrode, scale, clog, or embrittle. If negative pressure forms and the device were to fail, there is the potential for a large quantity of chemical to be pulled into the system creating an extremely dangerous, and preventable, situation for your customers. Waterford Waterworks Sanitary Survey Report Page 5 of 15  21 4. Vermin entering the water system are one of the most common reasons for unsafe bacteria samples. Screens are the last line of defense for preventing them from entering your water supply. As such, the department recommends that you continue to ensure that all screens are checked regularly for recent or potential failures. 5. Customer complaints can be vital information for determining things such as seasonal water quality issues, MCL violations above the taste and odor threshold (most likely several times higher than the MCL), issues with secondary contaminants, failures in treatment units, infiltration into wells, and many other issues. By scheduling a day or two a year to review past complaints, emerging or seasonal issues missed by normal water quality testing may be able to be identified. 6. Completing fire, leak, and storage studies can have many benefits to a system such as reduced insurance rates for businesses and evidence for capacity development. The department recommends that a comprehensive water system study be conducted every 10 years. 7. Of growing concern over recent years is insufficient staff to replace experienced individuals. It is recommended that the utility hires enough additional staff so that if one or more individuals were to leave that there could be dual coverage. Additionally, experienced operators are recommended to write O&M instructions for equipment that no longer has them. This way, if they were to suddenly or unexpectedly leave the utility, a new individual would have instructions to turn to. Furthermore, in recent years many systems have found that additional operators are almost a necessity for completing cross-connection programs on schedule. Some systems have also had costly mistakes made by inexperienced/undertrained/poorly supervised staff, in fact, for a few mistakes it would have been less expensive to hire an extra operator for 3 years before an experienced operator left than it was to hire a new operator AFTER the experienced operator retired were the mistake to be avoided. 8. With the exception of an actual emergency, the only way to know if everyone understands the emergency procedures that have been developed is to conduct exercises of who does what in an emergency situation. More information can be found at (https://www.epa.gov/waterresiliencetraining) or by contacting your DNR representative. By completing such exercises, you can approach the future with more confidence that you and your peers can handle whatever man or nature sends your way. 9. Colorimeters will gradually loose accuracy over time. To counter this, standards can be purchased to keep your machines accurate. This can be invaluable to help ensure that the readings you see are the same as what is actually happening in your process. 10. Cyber-attacks have been striking critical infrastructure across the United States with increased frequency in recent years. The following best management practices can be made to prevent a cybersecurity incident: • Update to the latest version of the operating system (e.g. Windows 10). • Use multiple-factor authentication to access critical applications. • Use strong passwords to protect remote access credentials. • Update user access lists to critical programs regularly (e.g. Employee retires) • Train users to identify and report attempts at social engineering. Identify and suspend access of users exhibiting unusual activity. • Ensure anti-virus, spam filters, and firewalls are up to date, properly configured and secure. • Audit network configurations and isolate computer systems that cannot be updated. • Only use secure networks and consider installing a virtual private network (VPN). Waterford Waterworks Sanitary Survey Report Page 6 of 15  22 • Restrict all remote connections to SCADA systems, specifically those that allow physical control and manipulation of devices within the SCADA network. One-way unidirectional monitoring devices are recommended to monitor SCADA systems remotely. 11. Current water loss at Waterford Waterworks is at 16%, above the recommended maximum amount of 10%. The department recommends the utility conduct a leak detection study if one has not been conducted recently. 12. Several areas of the Waterford Waterworks distribution system contain undersized 4 inch mains. The department recommends replacing these with larger sizes when appropriate. Larger sized mains can be beneficial to fire flows in emergency situations. Water Quality Monitoring and Reporting Your system has a good general record of compliance with monitoring and reporting requirements. We appreciate your continued efforts in complying with the Safe Drinking Water Act requirements. All monitoring location are required to have a unique Site ID, address, and sampled contaminates assigned to them. If a sampling site needs to be changed, this change must be approved before the site can be officially used for sampling. Required Reports, Records, and Utility Programs • Annual Monitoring Schedule: The Utility has excellent record of reporting according to the schedule. (0 M/R violations in the last 10 years) • Monthly pumpage reports (EMOR): The Utility has good record of submitting monthly reports. (2 missed in the last 10 years) • Wellhead Protection: The Utility has implemented this program in accordance with NR 811.12(6). • Well Pump Maintenance: The Utility has implemented this program in accordance with NR 810.13(1). • Valve/hydrant exercising/maintenance/flushing: The Utility has not implemented this program in accordance with NR 810.13(2). • Meter testing/Calibration: The Utility has succeeded in testing and/or calibrating master meters on wellhouses, high lift pumping stations, booster pumping stations, and metering stations in accordance with NR 810.13(2)(e). • Emergency Power Exercising: The Utility has succeeded to exercise emergency power in accordance with NR 810.13(1)(d). • Extended Well Agreement: N/A • Monitoring Assessments: A monitoring assessment application must be completed every three years to maintain monitoring waivers and reduced monitoring for applicable SDWA contaminants Operator Certification Chapter NR 114 specifies the requirements for how operators must be certified. The Utility must employ at least one person who is fully certified for all classifications/aspects of the water system. The water system must also designate the operator in charge (OIC). All operators must attend continuing education classes and submit evidence of attendance when renewing their certificates. The OIC must be accessible at all times (24/7) and any changes to OIC must be reported to the department no later than 30 days after the changes have been made per NR 114.31. Waterford Waterworks Sanitary Survey Report Page 7 of 15  23 As a reminder, all certified waterworks operators must complete at least 18 hours of approved training every three years to retain their certification. As a reminder, all certified waterworks operators must complete at least 18 hours of approved training every three years to retain their certification. Water System Security We recommend that you conduct a daily security check of your entire drinking water system to insure doors are locked and windows secured and free of any potential vandalism. It is recommended that any areas with ground level storage have motion activated security cameras to alert the system of potential threats. Capacity Development Evaluation This sanitary survey serves as an evaluation of the capabilities of your water system. Your system appears to have adequate technical, managerial, and financial capacity to provide safe drinking water at the time of this inspection. The ability to plan for, achieve, and maintain compliance with applicable drinking water standards appears to be adequate. • Citing information from the Utility and the PSC, the Utility appears to have an average net operating income (NOI) of 250,000 per year. • Citing information from the Utility and the PSC, the Utility appears to have 90 days of operating cash on hand. Water System Analysis From a preliminary source capacity analysis, storage capacity analysis, and distribution system analysis from data provided by the Utility, it appears that the Utility meets the standards for source capacity, storage capacity, total capacity, and distribution system. Water Loss Evaluation Per PSC 185.85, the Waterford Waterworks is a Class C Utility (between 1,000 and 4,000 connections) is higher than 10%, the recommended limit set by the DNR, but is in compliance with the PSC water loss limits set by PSC 185.85. The latest water loss data is as follows: • Non-Revenue Water Loss is 16%. (Limit is 30%) • Total Water Loss is 7%. (Limit is 15%) PSC may require a public utility to conduct a leak detection survey of its distribution system if, for three consecutive years, the public utility's percentage of water loss exceeds 15%. The department recommends that the Utility continue to find and correct sources of water loss. System Summary The Waterford water system is owned and operated by the Village of Waterford and serves a population of approximately 5000 people. The water system consists of: • one pressure zone(s) • Aeration system for the ascetic treatment of iron • Hypochlorite chemical addition for disinfection • 4 wells and 3 wellhouses Waterford Waterworks Sanitary Survey Report Page 8 of 15  24 Well # Pumping Capacity Depth (feet) Constructed (GPM) 1 300 135 04/07/1981 3 220 136 10/13/1997 4 540 82 04/16/2001 5 550 402 11/09/2001 Storage Size (Million gallons) Last Inspection Inspection Type Tower 1 0.2 2018 Drain Down Tower 2 0.4 2021 Drain Down The next sanitary survey of your system is scheduled to take place in 2025.
