​​​​​​​​​​​​​​​​​​Reporting Guidelines

Guidelines for water systems to document updates such as changes to inventory, contact information, and sampling points, and for labo​ratories submitting data to the Division of Water.
For assistance, contact us at ​​.

​Water systems must notify the Division of Water whenever there are changes to their water system, distribution system, or population served. Use the templates on this page to notify Division of Water about the following:
  • New consecutive connection (for example, when a water system starts purchasing or selling water to a new system) (401 KAR 8:100 Section 2)
  • Changes in population (401 KAR 8:200, Section 3)
  • Changes in the number of meters (use the Annual Data form)
  • Changes in operators (401 KAR 8:030, Section 1(6))
  • New contact person (administrative, owner, or emergency)
  • Changes in sampling point locations for chemical or bacteriological testing, including new locations added
  • Check Drinking Water Watch to see what sampling locations DOW currently has listed.

All templates and forms can be sent to the Division of Water using eForm 169. ​​

New Rule Implementation​​

​The Lead and Copper Rule Revisions (LCRR), promulgated in December 2021 by the EPA, made changes to the 1991 Lead and Copper Rule (LCR). 

The key near-term provision of the LCRR requires water systems to develop a  Service Line (SL) Inventory which must be submitted to DOW by October 16, 2024. An initial SL Inventory will be required from all public water systems (community and non-transient non-community systems), even if they do not have any lead service lines. Visit the links located below and to the right for more information, and check back regularly for updated guidance. 

The EPA has indicated that the LCRR supports near-term development of actions to reduce lead in drinking water, and will propose additional rulemaking to strengthen key elements of the revised rule. It anticipates finalizing Lead and Copper Rule Improvements (LCRI) before October 16, 2024, which is the first compliance date in the LCRR. Some of the provisions in the LCRR may be changed in the LCRI. The DOW will provide further information regarding the LCRI when it becomes available.

For more information contact Elizabeth Dowling,, 502-782-0965.​

On December 6, 2023, the EPA released the Proposed Lead and Copper Rule Improvements (LCRI), with a 60-day public comment period ending February 5, 2024. See the Federal Register for the full proposal. The Division of Water worked closely with the Lead in Drinking Water Workgroup to review the proposed rule and develop comments. The EPA plans to release the final LCRI before the October 16, 2024 compliance deadline of LCRR.​

March 28, 2023, EPA announced a Notice of Proposed Rulemaking that would strengthen the Consumer Confidence Report (CCR) Rule making annual drinking water quality reports with important public health information more accessible to residents and businesses across the country.

When finalized, EPA’s proposal would:
  • Improve the readability, clarity, and understandability of water quality reports
  • Enhance risk communication
  • Encourage modern electronic delivery options
  • Clarify information regarding lead levels and efforts to reduce lead in drinking water
  • Provide translation for customers with limited English proficiency
  • Require reports be issued twice a year (for systems that serve 10,000 or more people)
  • Require states to submit compliance monitoring data to EPA
EPA is accepting public comments on the proposed Revised CCR Rule through May 22, 2023.

For more information, contact Cortni Edwards​ 502-782-1582.​

​​Drinking Water ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Regulations

The state regulations for public water systems in Kentucky can be found in 401 KAR Chapter 8​. These are unofficial copies and the official copies can be found in the Kentucky Administrative Regulations Service and the monthly Administrative Register of Kentucky. To obtain a copy of these, contact the Legislative Research Commission at 502-564-8100, ext. 564. The national drinking water rules can be found in 40 CFR part 141 and 143.​

​As part of the Right-to-Know Rules the Consumer Confidence Report Rule was implemented in 1998. All Community Water Systems (CWS) that have at least 15 service connections and serves on average 25 people, are required to distribute this annual water quality report. The CCR is a tool for consumers to increase their awareness of the quality of their drinking water. The report includes information on the sources of drinking water, possible sources of contamination, and water treatment techniques. The CCR is also used to foster better relations and understanding between the consumer and the drinking water system on the importance of drinking water, the service that is provided to produce drinking water, and public participation opportunities to help make decisions that affect drinking water quality and public health.

CWS must send a copy of the CCR and the CCR certification form after the CCR has distributed to the public, but before July 1st annually to the Division of Water (DOW). The CCR is to include data from January 1st to December 31st of the previous year. CWSs that sells water to other CWS are required to deliver data and information the buying CWS needs to complete their CCR, no later than April 1st, annually, unless a later date is mutually agreed upon.

Distribution Methods Requirements:

  • Population < 500 notify customers by mail, door to door delivery or posting that the report is available upon request
  • Population < 10,000 directly mail or opt for a mailing waiver and publish in newspaper
  • Population > 10,000 mail or otherwise directly deliver
  • Population > 100,000 mail or otherwise directly deliver, also put on publicly accessible website
  • All CWS can use electronic delivery, aka eCCR, no matter what the population size
            - Notification of the availability of the eCCR must be directly delivered with the URL address to access the eCCR
  • All CWS must also perform a Good Faith Efforts (GFE) distribution to reach consumers that do not receive a water bill


A complete CCR package will contain:

  • A completed CCR Certification
  • A hardcopy of the CCR that was distributed to the public
  • Proof of electronic or newspaper delivery, if either method is used   
  • A list of public posting locations is preferred.


The CCR materials provided, while not comprehensive, are an excellent starting point for understanding the rule. For some CCR resources, please see the documents, at right, and links, below.

​The Lead and Copper Rule (LCR), created in 1991 by the EPA is a treatment technique requiring systems to monitor drinking water at customers’ taps. The number of samples is based on the population within their distribution system and focuses on households that contain lead pipes, connections served by lead service lines, and copper pipes with lead solder.
After the initial sampling period of two consecutive six-month periods, and there are no exceedances of the action level, sampling is then reduced to annual sampling for the next two consecutive years. If there are still no exceedances, sampling is then moved to once every three years, from June through September. If more than 10 percent of the copper levels exceed the action level (AL) of 1.3 parts per million (ppm) and more than 10 percent of the lead samples exceed the action level of 15 parts per billion (ppb), additional sampling and treatment techniques to control corrosion, are required. If the lead AL is exceeded, systems are required to monitor some water quality parameters, distribute public educational materials and may have to replace any lead service lines within the distribution system. The property owner is responsible for any lead fixtures, solder, or pipes after the meter.

The LCR materials provided, while not comprehensive, are an excellent starting point for understanding the rule. For some LCR resources, please see the documents, at right, and links, below.

As part of the Right-to-Know Rules Public Notifications are an important form of contact between the water system and the consumers they serve, when problems occur. It is a consumer’s right to know what happened and how it is being or has been corrected. There are ten key elements to every Public Notice and three tier classifications depending on the seriousness of the issue. Delivery options depend on the tier of violation issued.  Failure to notify the public in the required time period, will result in further violations. The complete Public Notification package needs to be submitted to the Kentucky Division of Water within 10 days of final distribution to the public.

  • Tier 1 violations have 24 hours to notify the public of possible immediate health issues.
  • Tier 2 violations have up to 30 days to notify the public of possible health issues.
  • Tier 3 violations have up to 12 months to notify the public of issues that do not have a direct impact on health.


There are 10 required elements in a public notice. Notices must contain:

  • A description of the violation that occurred, including the contaminant(s) of concern, and  the contaminant level(s);
  • When the violation or situation occurred;
  • The potential health effects (including standard required language);
  • The population at risk, including subpopulations vulnerable if exposed to the contaminant in their drinking water;
  • Whether alternate water supplies need to be used;
  • What the water system is doing to correct the problem;
  • Actions consumers can take;
  • When the system expects a resolution to the problem;
  • How to contact the water system for more information; and
  • Language encouraging broader distribution of the notice

A complete Public Notice package will contain:

  • A completed and signed Public Notice Certification
  • A copy of the PN direct delivered for the primary method
  • A copy of the PN Good Faith Efforts for the secondary method
  • A list of locations of public postings is preferred, if the method is used for the secondary method

The purpose of the Surface Water Treatment Rules (SWTRs) is to reduce illnesses caused by pathogens in drinking water. The disease-causing pathogens include Legionella, Giardia lamblia, and Cryptosporidium. SWTR applies to all water systems using surface water sources or ground water under direct influence of surface water (GWUDI) and developed treatment technique requirements for filtered and unfiltered public water systems to protect against acute adverse health effects from pathogens.

Interim Enhanced Surface Water Treatment Rule (IESWTR)

The IESWTR improved on control of microbial contaminants by building on treatment techniques and requirements of the SWTR including Turbidity monitoring and performance standards.

Turbidity Monitoring Requirements
Combined Filter Effluent – performed every four hours for compliance standards
Individual Filter Effluent – Continuously monitored (every 15 minutes) to assess filter performance 

Turbidity Performance Standards
- ≤ 0.3 NTU at least 95 percent of the ,measurements taken each month
- Maximum level of 1 NTU

The IESWTR materials provided, while not comprehensive, are an excellent starting point for understanding the rule. For some IESWTR (turbidity) resources, please see the documents, at right, and links, below.

For more information contact the IESWTR (turbidity) Rule Manager: Tekoyia (TK) Brown 502-782-6902.

Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR)

The Long Term 2 Enhanced Surface Water Treatment Rule addresses the health effects associated with Cryptosporidium in surface water.  The rule requires all surface water and ground water under the direct influence (GWUDI) systems to conduct source water monitoring for Cryptosporidium and/or E. coli for limited periods of time. 

Based on monitoring results, water systems are classified into “bins” and are required to provide additional levels of treatment depending on the bin classification they reside in. Additional treatment can be obtained selecting from one or more “microbial toolbox” treatment options.  

​ ​ ​ ​ ​​ ​Additional Cryptosporidium treatment requirements: ​ ​ ​
​Bin​Conventional Filtration​Direct Filtration​Slow Sand or Diatomaceous Earth Filtration

The Lead and Copper Rule Revisions (LCRR), promulgated in December 2021 by the EPA,  made changes to the 1991 Lead and Copper Rule (LCR). 

For information on implementing the new provisions of the LCRR, visit the New Rule Implementation Page, LCRR section.

Some LCRR provisions enhance or modify the requirements of the original LCR, including: 
  • A requirement for community and non-transient, non-community water systems to develop a Service Line Inventory 
  • Changes to tap sampling procedures and schedules 
  • Increased communications with customers and schools 
  • Tap sampling at schools and day care centers ​
  • Increased requirements for lead service line replacements ​
  • ​​​Changes to treatment technologies used by water systems ​
  • A new trigger level and a find-and-fix requirement 
Under the LCRR, lead and copper action levels remain the same as the 1991 LCR. Until the LCRR goes into effect in October 2024, water systems are required to continue monitoring
for lead and copper according to the same protocols they have been using. Contact the Division of Water (DOW) with any questions about lead and copper sampling.

Inorganic Contaminants, Volatile Organic Contaminants, Synthetic Organic Contaminants
All public water systems (PWS) must adhere to the sampling of these 65 contaminants, depending on their water source, type, and size. The general schedule is that ground water systems sample either every year or once every three years and surface water systems are every year. If a system has exceeded any of the Maximum Contaminant Levels (MCLs), that schedule could change per contaminant. To find sampling requirements, view the PowerPoint in the guidance documents for Chems.
Asbestos enters drinking water through asbestos cement pipes in the distribution system. All systems must sample once in the first three year compliance period of each nine year compliance cycle, starting in 2020-2022, if they have asbestos pipes. If a purchasing system does not have asbestos pipes, a waiver can be requested.
Arsenic standards were lowered in 2001, from 50 parts per billion (ppb) to 10ppb (or 0.010 parts per million (ppm)). With numerous links to a variety of cancers and effects, the newer standard went into effect to offset any long-term exposure.
The nitrate standard is 10ppm (or 10mg/L) and nitrite is 1ppm (or 10mg/L).  Once nitrates are converted into nitrites in the body, they disrupt the oxygen-carrying capacity and can lead to the acute condition known as Blue Baby Syndrome.

The Chem materials provided, while not comprehensive, are an excellent starting point for understanding the rule. For some Chem resources, please see the documents, at right, and the links, below.

​The Stage 1 Disinfectants and Disinfection Byproducts Rule (DBPR) reduces drinking water exposure to disinfection byproducts. Disinfection Byproducts are formed when Natural Organic Matter reacts with Disinfectants used in the drinking water treatment process. 
In 2006 the Stage 2 DBPR strengthened public health protection by tightening compliance monitoring requirements for Trihalomethanes (TTHM) and Haloacetic acids (HAA5).  Taken together, the Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts Rules (DBPRs) improve drinking water quality.
All community and nontransient noncommunity public water systems must comply with DBPR by complying with established maximum contaminant levels (MCLs) for contaminants and maximum residual disinfection levels (MRDLs) for disinfectants.

If an operational evaluation level is exceeded, a system must evaluate practices and DBP mitigation actions. The PWS must submit a written report (OEL form) to Division of Water no later than 90 days after being notified of the analytical result that caused the exceedance.

Total Organic Carbon (TOC) Removal
All Surface Water and GWUDI public water systems using conventional filtration are required to remove a certain percentage of DBP precursors measured as TOC. The percentage removal must be achieved unless the system meets alternative criteria.

Originally established in 1977, the Final Rule was published in 2000 with new monitoring requirements. All community water systems (CWS) are to sample and some will not have to sample for beta particles and photon radioactivity. Sampling occurs at the entry point to the distribution system (EPTDS) and depending on those results, the sampling schedule can change. - If initial results, once averaged for each contaminant, are below the detection limit then each EPTDS is sampled every nine (9) years.
- If initial results, once averaged for each contaminant, are great than or equal to the detection limit, but are less than or equal to one half of the maximum contaminant level (MCL), then each EPTDS is sampled every six (6) years.
- If initial results, once averaged for each contaminant, are great than one half of the (MCL), but less than or equal to the MCL, then each EPTDS is sampled every three (3) years.
- If any of the EPTDS are above the MCL, the system must return to sampling quarterly until four consecutive quarterly samples are found below the MCL.

​Under the National Secondary Drinking Water Regulations (NSDWRs) non-mandatory water quality standards were set for 15 contaminants with secondary maximum contaminant levels (SMCLs). While they are not federally enforceable and do not present health concerns, they can produce aesthetic (taste, odor and color), cosmetic (skin discoloration from silver and tooth discoloration from fluoride), and technical issues (scaling, sedimentation, and corrosion). Special public notices are required for exceeding the fluoride SMCL of 2.0 parts per million (ppm) or mg/L, but not exceeding the fluoride MCL of 4.0 ppm, within one year of learning of the exceedance. Samples must be taken at the Plant Tap.

​Total coliforms, in general do not present a health concern, rather they are used as an indicator of water quality and their absence is a sign of proper water treatment and the integrity of the distribution system. The TCR became effective 1990, with the RTCR in 2016. Sampling site plans must be approved for when and where samples are collected from the distribution system, and the sample must be representative of the distribution water quality. The number of monthly samples is determined by population size, but can be increased by request of the system. If a system increases their number of monthly samples, they are required to sample that number until they request otherwise. The test is presence/absence, with any present samples being resampled, as a set of three “repeat samples” at the original site, within five connections upstream of the original site, and within five connections downstream of the original site, within 24 hours of learning of a positive sample. The repeat sampling sites must be included in the sampling plan. Level 1 and Level 2 Assessments were instituted under the RTCR and are used as a method to assess the system to locate areas vulnerable to contamination. Level 1 Assessments are completed by the system, whereas Level 2 Assessments are completed by Drinking Water Compliance and Technical Assistance staff.

Seasonal Start-up requirements, for non-community public water systems (PWS), began in 2016 and are required annually. 401 KAR 8:200 and 40 CFR 141 Subpart Y. The Seasonal Public Water System Start-up Requirements and Checklist form is to be completed before opening to the public, submitted to the Kentucky Division of Water once completed, and retained for site inspections and sanitary surveys. 

The RTCR/TCR materials provided, while not comprehensive, are an excellent starting point for understanding the rule. For some RTCR/TCR resources, please see the documents, at right, and the links, below.

The Ground Water Rule became effective in 2006, to reduce incidents of microbial pathogens in public water systems distribution ground water. All systems that use ground water, including consecutive systems, except those that combine all of the groundwater with surface water and those under the direct influence of surface water before treatment, must adhere to the rule.
The Triggered Source Water Monitoring requirement is used to evaluate possibilities of fecal contamination when total coliforms (TC) are found to be present during routine monitoring. This monitoring is triggered if a system does not provide or conduct 4-log treatment, a positive routine total coliform sample is found, or a consecutive system has a positive routine total coliform sample. Once triggered the system is required to collect one source sample from each of the sources in use at the time of a positive TC sample. Samples are to be collected within 24 hours of learning of a positive sample, before the treatment process, and are to be analyzed for fecal contamination using an approved method. If the initial sample is fecal positive five additional samples are to be collected within 24 hours of receiving the results. If any of the additional samples are also fecal positive, correction actions must occur.
