Can You Drink Tap Water in Louisville?

Yes, Louisville's tap water is generally considered safe to drink as Louisville has no active health based violations of the Safe Drinking Water Act (SDWA) that we are aware of. Other factors such as lead piping in a home, or low levels of pollutants on immunocompromised individuals, should also be considered, however. To find more recent info we might have, you can check out our boil water notice page, the city's water provider website, or Louisville's local Twitter account.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Louisville's water utility, Louisville Water Company, had 0 violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. This assessment is based on the Louisville Water Company water system, other water systems in the city may have different results.

While tap water that meets the EPA health guidelines generally won’t make you sick to your stomach, it can still contain regulated and unregulated contaminants present in trace amounts that could potentially cause health issues over the long-run. These trace contaminants may also impact immunocompromised and vulnerable individuals.

The EPA is reviewing if it’s current regulations around pollutant levels in tap water are strict enough, and the health dangers posed by unregulated pollutants, like PFAS.

Water Quality Report for Louisville Tap Water

The most recent publicly available numbers for measured contaminant levels in Louisville tap water are in its 2020 Water Quality Report. As you can see, there are levels which the EPA considers to be acceptable, but being below the maximum allowable level doesn’t necessarily mean the water is healthy.

Lead in tap water, for example, is currently allowed at up to 15ppb by the EPA, but it has set the ideal goal for lead at zero. This highlights how meeting EPA standards doesn’t necessarily mean local tap water is healthy.

EPA regulations continue to change as it evaluates the long term impacts of chemicals and updates drinking water acceptable levels. The rules around arsenic, as well as, lead and copper are currently being re-evaluated.

There are also a number of "emerging" contaminants that are not currently. For example, PFAS (Per- and polyfluoroalkyl substances), for which the EPA has issued a health advisory. PFAS are called "forever chemicals" since they tend not to break down in the environment or the human body and can accumulate over time.

We recommend looking at the contaminants present in Louisville's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

Louisville Tap Water Safe Drinking Water Act Violation History - Prior 10 Years

Below is a ten year history of violations for the water system named Louisville Water Company for Louisville in Kentucky. For more details please see the "What do these Violations Mean?" section below.

Is there Lead in Louisville Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Louisville water system, Louisville Water Company, between sample start date and sample end date, were at or below, 0.0011 mg/L of lead in Louisville water. This is 7.3% of the 0.015 mg/L action level. This means 10% of the samples taken from Louisville contained more lead.

While Louisville water testing may have found 0.0011 mg/L of lead in its water, that does not mean your water source has the same amount. The amount of lead in water in a city can vary greatly from neighborhood to neighborhood, or even building to building. Many buildings, particularly older ones, have lead pipes or service lines which can be a source of contamination. To find out if your home has lead, we recommend getting you water tested.

No amount of lead in water is healthy, only less dangerous. As lead accumulates in our bodies over time, even exposure to relatively small amounts can have negative health effects. For more information, please check out our Lead FAQ page.

Are there PFAS in Louisville Tap Water?

Currently, testing tap water for PFAS isn’t mandated on a national level. We do have a list of military bases where there have been suspected or confirmed leaks. There appears to be at least one military base - Louisville Air National Guard Base - near Louisville with suspected leaks.

With many potential sources of PFAS in tap water across the US, the best information we currently have about which cities have PFAS in their water is this ewg map, which you can check to see if Louisville has been evaluated for yet.

Our stance is better safe than sorry, and that it makes sense to try to purify the tap water just in case.

What do these Violations Mean?

Safe Drinking Water Act Violations categories split into two groups, health based, and non-health based. Generally, health based violations are more serious, though non-health based violations can also be cause for concern.

Health Based Violations

  1. Maximum contaminant levels (MCLs) - maximum allowed contaminant level was exceeded.
  2. Maximum residual disinfectant levels (MRDLs) - maximum allowed disinfectant level was exceeded.
  3. Other violations (Other) - the exact required process to reduce the amounts of contaminants in drinking water was not followed.

Non-Health Based Violations

  1. Monitoring and reporting violations (MR, MON) - failure to conduct the required regular monitoring of drinking water quality, and/or to submit monitoring results on time.
  2. Public notice violations (Other) - failure to immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health.
  3. Other violations (Other) - miscellaneous violations, such as failure to issue annual consumer confidence reports or maintain required records.

SDWA Table Key

Field Description
Compliance Period Dates of the compliance period.
Status Current status of the violation.
  • Resolved - The violation has at least one resolving enforcement action. In SDWIS, this indicates that either the system has returned to compliance from the violation, the rule that was violated was no longer applicable, or no further action was needed.
  • Archived - The violation is not Resolved, but is more than five years past its compliance period end date. In keeping with the Enforcement Response Policy, the violation no longer contributes to the public water system's overall compliance status. Unresolved violations are also marked as Archived when a system ceases operations (becomes inactive).
  • Addressed - The violation is not Resolved or Archived, and is addressed by one or more formal enforcement actions.
  • Unaddressed - The violation is not Resolved or Archived, and has not been addressed by formal enforcement.

HOW WE MAKE YOUR DRINKING WATER - LOUISVILLE PURE TAP®

MESSAGE FROM THE EPA

 

 

 

Our treatment plants are supplied by water directly from the Ohio River or from groundwater that is naturally filtered through the riverbank.

COAGULATION

Louisville Water adds chemicals to the water to help natural particles such as clay and silt stick together.

FILTRATION

Finally, the water passes through filters containing sand and anthracite to remove any remaining particles. The finished water—Louisville pure tap®—then goes into a clear well, a large underground storage unit at the treatment plant, and is pumped out into the distribution system.

SEDIMENTATION

As the particles get bigger and heavier, they settle out and get removed from the water.

DISINFECTION

Once most of the particles are removed, chlorine is added to eliminate any remaining risk from pathogens present in the water. Ammonia is added to stabilize the disinfectant and keep the water safe as it travels through Louisville Water’s distribution system.

In order to ensure that tap water is safe to drink, the Envi- ronmental Protection Agency (EPA) prescribes regulations which limit the amount of certain contaminants in the water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in the bottled water that must provide the same protection for public health.

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline at 800.426.4791.

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive materials, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include:

  • Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
  • Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban

stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.

  • Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwa- ter runoff, and residential uses.
  • Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
  • Radioactive contaminants, which can be naturally-oc- curring or be the result of oil and gas production and mining activities.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-com- promised persons such as persons with cancer undergo- ing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 800.426.4791.

LEAD AWARENESS

NO MORE KNOWN PUBLIC LEAD LINES IN LOUISVILLE WATER’S DISTRIBUTION SYSTEM

Louisville Water began as Kentucky’s first public water provider in 1860 and until 1936 it was common to install a lead pipe, called a service line, that connected the utility’s drinking water to the customer’s water line. Louisville Water installed an estimated 74,000 lead service lines before 1936. Since then, Louisville Water has installed copper service lines except during World War II when lead was used again because of a suspected copper shortage. In the 1970s, the company began replacing those old lead lines with copper when they were found. In the 1990s, Louisville Water began an aggressive strategy to find and replace all lead service lines. In March of 2020, after 50 years and more than $50 million, Louisville Water announced it had successfully removed all its known public lead service lines from the distribution system. Only a small number of other utilities in the United States have reached this milestone.

CUSTOMERS MIGHT HAVE A PRIVATE LEAD SERVICE LINE

Some Louisville Water customers with older homes (those typically built before 1950) may have a private lead service line on their property that connects to Louisville Water’s line. A customer’s private service line begins at the property line connection and runs to the water shut-off valve inside the home.

Louisville Water may not currently have records for all private service line materials. If​ our records indicated that a portion of a customer’s service line may be lead, the customer was contacted about replacing this line. You can visit LouisvilleWater.com/Lead-Awareness and use our Private Service Line Lookup tool to see if we have information on your property. A licensed plumber can also check your line to see if it’s lead.

LOUISVILLE WATER WILL HELP WITH REPLACEMENT

Because replacing a service line can be expensive, Louisville Water will pay 50 percent of the cost, up to $1,500. If customers can’t afford this program and they meet eligibility requirements, Louisville Water Foundation’s grant program may pay the remaining replacement cost. Visit LouisvilleWater.com/Lead-Awareness for more information on this program, how to apply, and frequently asked questions.

INFORMATION ABOUT LEAD

Lead is a metal that is found in natural deposits in the environment, but it is rarely found in source water. Louis- ville’s drinking water does not contain lead when it leaves the treatment plants and as it travels through our distribution system.

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Louisville Water is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 5 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Please visit LouisvilleWater.com/Lead-Awareness to request a free water quality test kit for your home. More information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/

LEAD AND COPPER RULE

Copper Rule (LCR). For the LCR, we sample water at the customer’s tap at sites with known lead service lines or lead/copper solder. If lead concentrations exceed an Action Level of 15 ppb or copper concentrations exceed an Action Level of 1.3 ppm in more than 10 percent of customer taps sampled, the water system must undertake a number of additional actions to control corrosion on those lines.

Louisville Water’s 2020 monitoring found all samples were below EPA’s Action Level for both lead and copper. For more information visit LouisvilleWater.com/

Has your building been closed? Flush your lines When businesses and schools begin reopening buildings where water has been turned off, stag- nant, or under-used during the pandemic shut- down, it is essential that water pipes be flushed properly. Flushing water lines is an easy way to ensure that high water quality is maintained. It moves older water, that has been sitting in the pipes, out of the building and brings in fresh

Reminder

Always take extra precautions, the water may be safe to drink when it leaves the sewage treatment plant but it may pick up pollutants during its way to your tap. We advise that you ask locals or hotel staff about the water quality. Also, note that different cities have different water mineral contents.

Sources and Resources

There are many issues with the water supply in Louisville, Kentucky. In fact, the Environmental Protection Agency is warning that up to one fifth of the city’s supply may be contaminated with E-coli, a bacteria that can cause diarrhea, vomiting, and even stomach ulcers. This is especially alarming, as close to half of the people in Louisville live below the poverty line, making basic access to clean drinking water an extremely critical issue for them and their families.

Fortunately, there are some simple steps you can take to purify your own tap water, without having to use any expensive purifiers. While the water table in Louisville is usually pretty low, and rain is fairly rare, there are still chances that pollutants or other debris could slip through the faucet or the showerhead and get into your supply. By taking simple steps such as regularly cleaning out your showerheads and faucets, and reducing the amount of time you spend in the bathroom or cooking with water that has already been used, you can greatly reduce the chances that harmful chemicals will slip into your water.

The most efficient way to purify your water is by using a water purifier, which can provide you with crystal clear water at a very affordable price. While there are a lot of options available on the market, you should definitely consider purchasing a multi-stage selective filtration system. It is important to point out that most filters have a life expectancy of only about three months. This means that if you use your water on a regular basis, you need to replace the filter before the warranty expires. Also, be sure to check the Performance Data Sheet, which should outline all of the steps the system has to perform. A high-end filter can easily eliminate up to 99% of chemical contamination, making it an excellent investment for anyone who wants the best quality water possible.

Louisville Drinking Water

Recently, when Louisville drinking water was tested by a professional lab, there were over five thousand results that the lab discovered had the presence of at least one potentially harmful chemical in the water. This is especially true since all but one of the drinking water systems in Louisville have had to deal with legal battles with the EPA over the past couple of years because they did not test for and release regulated levels of chemicals in the drinking water. As the result of all of these legal battles, the Kentucky Environmental Protection Agency has placed several regulations over the last few years that were designed to protect the public from dangerous amounts of toxins that are commonly found in our water.

Because of all of this political pressure from the EPA and the courts that have ordered publicly owned treatment plants to release certain amounts of toxic chemicals into the environment, many people wonder just where all of the chemicals come from. Well, one answer might be obvious, if you live in Louisville, Kentucky and it’s your water supply. The fact is, all of the treated drinking water that goes through the treatment plant must be mixed with raw municipal sewage in order to become drinkable water. Without this step, you would be drinking raw sewage water instead of drinking the purified water that is provided by your public treatment plant.

Louisville Water Quality

The quality of water that circulates through Louisville, Kentucky is a topic of great interest to residents and businesses alike. It has been found that the water that is provided by the Louisville Waterworks has a lower than acceptable level of lead in it. This has been linked to the fact that a large number of the homes and businesses that are located in the City of Louisville are located within areas that have a high concentration of lead-based paint. With this in mind, the ability of the water to be clean and clear and to provide safe drinking water for those residents and businesses on a continuous basis is a major concern.

The water from the Louisville Waterworks does meet all standards and regulations pertaining to cleanliness and purity. However, it is up to the discretion of the residents of the city as to whether or not they wish to filter their own water. Although there may be some cost involved in doing this, there is nothing more harmful than using untreated water. Unfiltered water carries with it many diseases that can be harmful to health, such as: hepatitis, cholera, dysentery and several forms of cancer. If you wish to remove any potential threat to your health, it would be advisable to filter the water that is supplied to your home or office.

It is the responsibility of all residents of the Louisville Waterworks to have their water supply checked periodically. By doing so, you will be able to ensure that the water that is provided to you is clean and pure. If you wish to find out if the water quality in your area meets the required standards, you can send your water sample to the Louisville Waterworks lab for testing. Once you have tested the water, you will be able to determine what steps need to be taken in order to improve the water’s cleanliness. As long as the water is clean enough to drink, it is your responsibility to ensure that it meets all necessary safety standards.
