Can You Drink Tap Water in Racine?

Yes, Racine's tap water is generally considered safe to drink as Racine 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 or the city's water provider website.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Racine's water utility, Racine Waterworks, had 0 violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. There has been an active violation for Public Notice since Jan. 1, 2015. This assessment is based on the Racine Waterworks 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 Racine Tap Water

The most recent publicly available numbers for measured contaminant levels in Racine 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 Racine's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

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

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

For the compliance period beginning Jan. 1, 2015, Racine had 1 health-based Safe Drinking Water Act violation with the violation category being Treatment Technique Violation, more specifically, the violation code was Public Education which falls into the Chemicals rule code group, and the Lead and Copper Rule rule code family for the following contaminant code: Lead and Copper Rule.

For the compliance period beginning Jan. 1, 2015, Racine had 1 non-health based Safe Drinking Water Act violation with the violation category being Other Violation, more specifically, the violation code was Public Notification Violation for NPDWR Violation which falls into the Other rule code group, and the Public Notice Rule rule code family for the following contaminant code: Public Notice.

Is there Lead in Racine Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Racine water system, Racine Waterworks, between sample start date and sample end date, were at or below, 0.0047 mg/L of lead in Racine water. This is 31.3% of the 0.015 mg/L action level. This means 10% of the samples taken from Racine contained more lead.

While Racine water testing may have found 0.0047 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 Racine 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 - General Mitchell International Airport - near Racine 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 Racine 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.

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.

Racine Water - Frequently Asked Questions

HOW TO READ THE WATER QUALITY TABLE: USE THE DEFINITIONS HERE TO
understand what the scientific data means for your drinking water: The Compliance Level may be a substance’s highest level detected in the water, or an average concentration of all samples tested, depending on the regulation for the substance. If multiple samples were tested in 2020, the lowest and highest detected values are listed under Range of Detections. Regulated substances have Maximum Contaminant Levels (MCLs) set by the EPA. This is the highest level of the substance legally allowed in drinking water. Some contaminants also have Maximum Contaminant Level Goals (MCLGs). This is the level of a substance where there is no known or expected health risk. MCLGs allow for a margin of safety. MCLs are set as close to MCLGs as practical using the best available water treatment processes.

Racine Water Quality Report (Consumer Confidence Report)

The EPA mandates that towns and cities consistently monitor and test their tap water. They must report their findings in an annual Consumer Confidence Report. Below is the most recent water quality report from Racine's Water. If you would like to see the original version of the report, please click here.

EPA and Wisconsin Requirements for Racine’s Drinking Water

Unregulated Contaminants Monitoring Rule

The U.S. EPA uses the Unregulated Contaminant Monitoring

Water delivered by the RWU must be safe from microbes and chemical toxicity, and also safe from exposure to trace levels of chemicals over a lifetime of 80 years. Source water (Lake Michigan), treated finished water, distribution system water, and residential water throughout the city and surrounding communities are monitored for over 90 regulated contaminants. In 2020, the Racine Water Utility conducted over 53,000 in-house water quality analyses along with over a thousand tests by contracted laboratories. The Water Quality Table, found on the reverse side of this brochure, lists many substances tested by the RWU during 2020. Included in the table are the results for Cryptosporidium and Giardia from 2015-2017, which ended a 2-year long monitoring program. To ensure that tap water is safe, the EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration guidelines establish limits for contaminants in 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.

Lead in Drinking Water

Water that is too corrosive can dissolve lead and other contaminants from your home’s plumbing fixtures. For the sixth consecutive year, the RWU lead results were significantly below the EPA established 15 part per billion (ppb) action level. For 2020, the 90th percentile lead result was 4.7 ppb, with no samples exceeding the 15 ppb action level. The 90th percentile copper result was 0.23 ppm, with no samples exceeding 1.3 ppm action level. In 29 years of sampling, only one sample ever exceeded the copper action level. To see more details regarding lead and copper results, please refer to the 2020 Water Quality Table on the reverse side of this pamphlet. Lead in drinking water is rarely the sole cause of lead poisoning, but it can add to a person’s total lead exposure. All potential sources of lead in the household should be identified and removed, replaced, or reduced. It is possible that the lead levels in your home may be higher than at other homes in the area due to materials used in the construction of your home’s plumbing system. If you are concerned about lead levels in your water (young children are more vulnerable to lead than adults), you may wish to have your water tested. Flushing your tap water for 30 seconds to 2 minutes prior to using the water is an effective method to reduce exposure to lead. Additional information is available from the Safe Drinking Water Hotline at (800)-426-4791.

Sources and Contaminants

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 material. It can also pick up substances resulting from the presence of animals or humans. Substances that can be present in source water include:

Microbial contaminants, such as viruses and bacteria, which may come from wastewater treatment plants, septic systems, agricultural livestock operations, and wildlife

Inorganic contaminants, such as salts and metals, which can occur naturally or result from storm water 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 storm water 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 storm water runoff and septic systems

Radioactive contaminants, which occur naturally or result from oil and gas production and mining activities

Some people may be more vulnerable to contaminants found in drinking water than the general population. Immuno-compromised persons, such as persons with cancer undergoing 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 for infections. These people should seek advice about drinking water from their health care providers. EPA/ Centers for Disease Control guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants can be obtained by calling the EPA’s Safe Drinking Water Hotline at (800) 426-4791.

Rule (UCMR) to collect data for contaminants which currently do not have any health-base standards set under the Safe Drinking Water Act (SDWA). This testing program assists the EPA in determining occurrence of unregulated contaminants and whether future regulation is warranted. The UCMR program began 2001, with RWU participating in every round due to being a large water system serving > 100,000 people. Each round of the UCMR monitors as many as 30 contaminants every 5 years. For more information visit the EPA website:

Welcome to Racine’s

Drinking Water Quality Report

This brochure is a snapshot of your home’s water quality provided last year. Included are details about where your water comes from, what it contains, and how it compares to the Environmental Protection Agency (EPA) and State of Wisconsin standards. The Racine Water Utility’s (RWU) water quality meets or exceeds all Federal and State drinking water quality standards. The Racine Water Utility uses ”state of the art” membrane ultra-filtration and employs 34 State certified waterworks operators. We are committed to providing you with information, because informed customers are our best allies.

Water Source Supply

Water delivered to Racine customers is treated and purified water drawn from Lake Michigan. The lake provides abundant, high quality water for many major cities along its shores.

The Wisconsin Department of Natural Resources (WDNR) completed source water assessments across the state of Wisconsin in the early 2000s. The RWU source water assessment completed in April, 2003 determined the relative susceptibility of Lake Michigan to contamination in the Racine area. Although the water treatment plant protects its customers from potentially adverse health effects due to contamination, the source water assessment provides a first step guide for the community to implement preventative practices and limit contamination.

For more information go to: https://www.epa.gov/sourcewaterprotection

Next to disinfection of the water, the most important purification process is the removal of suspended particles. Particulate matter in the water may be disease causing micro-organisms or can provide hiding places for micro-organisms to escape disinfection chemicals. Turbidity is the measurement of water clarity. Water systems must meet clarity standards as listed in the above table. The RWU filters the treated water first through sand filters, and re-filters the water through membrane filters. The RWU’s maximum turbidity for water leaving the treatment plant for 2020 was 0.058 NTU, well below the established maximum allowed levels, and the turbidity was below 0.3 NTU 100% of the time. In 2020, the average peak turbidity was 0.021 NTU for water leaving the treatment plant.

How to Read the Water Quality Table: Use the definitions here to

understand what the scientific data means for your drinking water: The Compliance Level may be a substance’s highest level detected in the water, or an average concentration of all samples tested, depending on the regulation for the substance. If multiple samples were tested in 2020, the lowest and highest detected values are listed under Range of Detections.

Regulated substances have Maximum Contaminant Levels (MCLs) set by the EPA. This is the highest level of the substance legally allowed in drinking water. Some contaminants also have Maximum Contaminant Level Goals (MCLGs). This is the level of a substance where there is no known or expected health risk. MCLGs allow for a margin of safety. MCLs are set as close to MCLGs as practical using the best available water treatment processes.

Monitoring for unregulated contaminants is also conducted. Although these are substances that do not have MCLs, the EPA evaluates them when assessing future drinking water regulations. The MCL for lead and copper is known as the Action Level (AL). This is the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow. For compliance, 90% of all samples tested must be below the Action Level.

Turbidity is a measure of water clarity used to evaluate the effectiveness of the filtration system. One criterion for enforcement of the turbidity regulation is a Treatment Technique (TT). This is a water treatment process that is required by the EPA to reduce the level of turbidity in the water.

The Units of Measurement reported for each substance depend on the nature of the analytical measurement and the amount of the substance detected. Listed below are the abbreviations for these units.

ppm: parts per million or milligrams per liter

ppb: parts per billion or micrograms per liter

pCi/l: pico curies per liter, a measure of radioactivity

NTU: nephelometric turbidity units

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.
