Your Water System
Where Your Water Comes From
Your water Your water is pumped into the system from two wells (groundwater), which are 78 and 90 feet deep.
Your water is not treated (no chlorination, filtration, pH adjustment, etc.).
Source Water Protection Information
Drinking water comes from groundwater (wells and springs) and surface water (rivers, lakes, streams). Protecting these drinking water sources is key to sustaining safe drinking water supplies for this and future generations.
What you can do to protect source water:
- Ensure that your septic system is properly maintained.
- Use chemical fertilizers and pesticides sparingly, if at all.
- Don't dump any hazardous waste on the ground. This includes: motor oil, pesticides, paint or paint cans, mothballs, flea collars, household cleaners, medicines, etc.
Check the SWAP information for your water system:
The Washington State Department of Health Office of Drinking Water has compiled Source Water Assessment Program (SWAP) data for all community water systems in Washington. A source water assessment includes:
- A delineation (definition) of the source water protection area,
- An inventory of potential sources of contamination, and
- A susceptibility determination (how susceptible the source is to contamination).
An interactive map with data for your water system is available at: fortress.wa.gov/doh/swap/
If you have any questions, suggestions, or concerns, please contact our Customer Service Center, either by phone at (877) 408-4060 or through the Contact Us link.
To ensure that the high-quality water we deliver is not compromised in the distribution system, Washington Water has a robust cross-connection control program in place. Cross-connection control is critical to ensuring that activities on customers' properties do not affect the public water supply. Our cross-connection control specialists ensure that all of the existing backflow prevention assemblies are tested annually, assess all connections, and enforce and manage the installation of new commercial and residential assemblies.
Backflow can occur when certain pressure conditions exist either in our distribution system or within the customer's plumbing, so our customers are our first line of defense. A minor home improvement project—without the proper protections—can create a potentially hazardous situation, so careful adherence to plumbing codes and standards will ensure the community's water supply remains safe. Please be sure to utilize the advice or services of a qualified plumbing professional.
Many water-use activities involve substances that, if allowed to enter the distribution system, would be aesthetically displeasing or could even present health concerns. Some common cross-connections are:
- Garden hoses connected to a hose bib without a simple hose-type vacuum breaker (available at a home improvement store)
- Improperly installed toilet tank fill valves that do not have the required air gap between the valve or refill tube
- Landscape irrigation systems that do not have the proper backflow prevention assembly installed on the supply line
The list of materials that could potentially contaminate the water system is vast. According to the EPA, a wide variety of substances have contaminated drinking water systems throughout the country as a result of poor cross-connection control. Examples include:
- Antifreeze from a heating system
- Lawn chemicals from a garden hose or sprinkler head
- Blue water from a toilet tank
- Carbonated water from a soda dispenser
Customers must ensure that all plumbing is in conformance with local plumbing codes. Additionally, state law requires certain types of facilities to install and maintain backflow prevention assemblies at the water meter. Washington Water's cross-connection control staff will determine whether you need to install a backflow prevention assembly based on water uses at your location.
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 the 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.
Common sources of drinking water—both tap and bottled water—include rivers, lakes, streams, ponds, and reservoirs (surface water), and wells and springs (groundwater). As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material. Water can also 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, parasites, 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 stormwater runoff, and residential uses.
Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.
Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
In order to ensure that tap water is safe to drink, the Washington State Department of Health (DOH) and EPA prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The Food and Drug Administration (FDA) and Washington State Department of Agriculture regulations establish limits for contaminants in bottled water that must provide the same protection for public health.
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised people such as those with cancer undergoing chemotherapy, those 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.
Action level (AL): The concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow.
Lead and Copper 90th Percentile Value: Out of every 10 homes sampled, 9 were at or below this level. This must be less than or equal to the AL or additional steps must be taken.
Maximum containment level (MCL): The highest level of a contaminant allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
Maximum contaminant level goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
µmhos/cm: A measure of specific conductance.
N/A: Not applicable.
Not detected (ND): The result is less than the SDRL.
Nephelometric turbidity unit (ntu): A measure of water clarity.
pCi/L: PicoCuries per liter. A measure of radioactivity.
ppb: Parts per billion (µg/L, micrograms per liter)
ppm: Parts per million (mg/L, milligrams per liter)
State detection reporting limit (SDRL): The minimum reportable detection of an analyte as established by DOH. If the test result is less than the SDRL, the contaminant is considered to be not detected.
Secondary maximum contaminant level (SMCL): These standards are developed as guidelines to protect the aesthetic qualities of drinking water and are not health based.
The source codes indicate major sources of contaminants in drinking water.

2021 Water Quality
Your water is tested for more than 150 contaminants for which state and federal standards have been set.
Tables 1 & 2 list all primary contaminants that were detected at or above the state detection reporting limit SDRL, along with their respective MCLs. Primary MCLs primary standards protect public health by limiting the levels of these contaminants in drinking water.
Table 3 lists secondary contaminants of interest to many consumers, as well as any unregulated contaminant detections. Secondary contaminants have no known health effects but can affect the aesthetic properties of water taste, odor, and appearance. Unregulated contaminants are those for which EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to help EPA determine their occurrence in drinking water and potential need for future regulation.

1 Due to the copper exceedance in 2018, the system is currently under construction for corrosion control treatment, which will be completed in 2022.
2 Results from the most recent round of routine monitoring in 2018 exceeded the copper AL of 1.3 ppm, but not the lead AL of 15 ppb. When an action level is exceeded, this is not a violation, but state and federal drinking water regulations require the water system to complete certain actions within a specific timeline. Not meeting the due dates for these follow-up actions would be a violation. Please see page 10 for detailed information regarding the additional steps being taken, the health effects of copper in drinking water, and easy ways you can reduce your exposure.
3 The EPA recommends 20 ppm sodium as a level of concern for consumers who must restrict their dietary intake.
4 When reading the hardness value, 0–75 ppm is considered "soft" water, 75–150 ppm is "moderately hard," 150–300 ppm is "hard," and >300 ppm is "very hard." To convert to grains per gallon of hardness, divide total hardness by 17.1.
5 Lead and copper are regulated at customer taps (see Table 2 for those results), not at the source, which is what these results represent. This is because lead and copper in drinking water do not typically come from the water source. They come from the plumbing that serves, or is inside, the customer's home, from corrosion of lead and copper-containing plumbing or fixtures, or the lead solder that connects copper pipes.
Special Educational Information
Copper Action Level Exceedance (Table 2)
Copper in drinking water comes from corrosion of household plumbing and fixtures. All public water systems are required to monitor the levels of lead and copper at customer taps every three years in order to ensure that they stay below safe levels for drinking. Although the water utility has no control over household plumbing materials, we are responsible for ensuring that the water being served to homes is not corrosive toward the household plumbing (i.e, contributing to the leaching).
If more than 10% of tap samples collected by customers exceed the copper action level (1.3 ppm) or the lead action level (15 ppb), state and federal drinking water regulations require us to complete certain steps within a specific timeline. Exceeding the action level (AL) is not a violation, but not completing the follow up steps by their required deadline would be.
During routine monitoring in June 2018, the copper AL of 1.3 ppm was exceeded, at 1.75 ppm. The lead AL of 15 ppb was not exceeded, at 2 ppb. Our next required step was to collect samples in August and October 2018 from each source (well) to determine if the groundwater is corrosive. Groundwater with naturally occurring dissolved carbon dioxide, low pH (acidic), low alkalinity, or very low mineral content, can contribute to corrosion of plumbing materials. Results of these tests confirmed that the groundwater has these characteristics. A professional engineer evaluated the water quality data and prepared a recommendation for mitigating corrosion. This report was submitted to the Department of Health in March 2019, and DOH approved the engineer's treatment recommendation in June 2019. A pilot study was then conducted in May–June 2020 at one of the homes that exceeded the copper Action Level. Results of this study and the project report were approved by DOH in May 2021. Construction is planned for the second half of 2021. The approved treatment will raise the pH of the source water with limestone (calcium carbonate), which also coats the interior of the water pipes, creating a barrier between the pipe and the corrosive water.
Potential Health Effects of Copper
Although copper is an essential mineral in the diet, too much copper can cause health problems. Copper is widely distributed within the tissues of the body, but accumulates primarily in the liver and kidneys. A single dose of 15 mg of copper can cause nausea, vomiting, diarrhea, and intestinal cramps. Severe cases of copper poisoning have led to anemia and to disruption of liver and kidney functions. Individuals with Wilson's or Menke's diseases are at higher risk from copper exposure.
How You Can Reduce Exposure to Copper in Drinking Water
- Run your water to flush out copper. When your water has been sitting for several hours, simply run the water for 30–60 seconds or until it becomes cold or reaches a steady temperature before using it for drinking or cooking. The longer water has been sitting in the pipes, the more dissolved metals it may contain.
- Use only cold water for drinking, cooking, and making baby formula. Hot water may contain higher levels of copper.
Washington Water is compliant with health and safety codes mandating use of lead-free materials in water system replacements, repairs, and new installations. We have no known lead service lines in our systems. We test and treat (if necessary) water sources to ensure that the water delivered to customer meters meets water quality standards and is not corrosive toward plumbing materials.
The water we deliver to your home meets lead standards, but what about your home's plumbing? In Washington state, lead in drinking water comes primarily from materials and components used for in-home plumbing (for example, lead solder used to join copper plumbing, and brass and other lead-containing fixtures). Therefore, the Lead and Copper Rule is a critical part of our water quality monitoring program, and we follow it completely. This rule requires us to test water inside a representative number of homes that have plumbing most likely to contain lead and/or lead solder. This test, along with other water quality testing, tells us if the water is corrosive enough to cause lead from home plumbing to leach into the water. If the Action Level (the concentration of a contaminant which, when exceeded, triggers action which a water system must follow before it becomes a health concern) is exceeded, either at a customer's home or system-wide, we work with the customer to investigate the issue. If the problem is system-wide, we will implement corrosion control treatment at the source before the lead levels create a health issue.
Elevated levels of lead, if present, can cause serious health problems, especially for pregnant women and children. If your home's plumbing contains lead piping or pipe fittings, lead solder, or brass fixtures that may contain lead, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to two 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 by a certified lab. 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 www.epa.gov/safewater/lead.
Results of our lead monitoring program, conducted in accordance with the Lead and Copper Rule, can be found in Water Quality Tables 2 and 3.
About Monitoring Waivers (reduced monitoring)
Drinking water sources are sampled and tested a minimum of every six to nine years for an array of organic chemicals including:
- Volatile organic chemicals (VOCs): Human-made chemicals that are used and produced in the manufacture of paints, pharmaceuticals, and refrigerants. Typical VOCs are components of petroleum fuels, paint thinners, and dry cleaning agents.
- Synthetic organic chemicals (SOCs): Human-made chemicals that are used as herbicides, pesticides ,and in the manufacture of plastics.
Sampling frequencies for these groups of organic chemicals can vary depending on the county in which your water system is located, whether the source has been granted a monitoring waiver, and whether there have been past detections of any of these organic contaminants.
Monitoring waivers are granted by the DOH and are based on a source's susceptibility rating (risk of contamination), water quality history, and information gathered from across the state.
If there were detections of organic contaminants obtained during the most recent round of compliance monitoring (2016–2021 for VOCs; 2013–2021 for SOCs), they are shown in the water quality data tables. If there are none reported in the tables, there were none detected.
Drinking water sources are sampled and tested a minimum of every six years for radioactive contaminants (radium 228 and gross alpha). These contaminants can be naturally occurring or the result of oil and gas production and mining activities.
If there were any detections obtained during the most recent round of compliance monitoring (2016–2021), they are shown in the water quality data tables. If there are none reported in the tables, there were none detected.
Water is a precious, limited resource. In the Pacific Northwest, drinking water for our growing population competes with other uses that include agriculture, industry, recreation, and maintaining an adequate stream flow for fish.
Washington Water strives to be a leader in the water industry, and we encourage our customers to be good stewards of our water resources. We monitor the amount of water we withdraw from aquifers in Washington, and track water losses along with water sold to our customers to ensure compliance.
Washington Water also continues to invest diligently in our infrastructure to reduce the amount of water lost to pipeline leaks and are updating our assessment of the impacts of climate change on water supply and demand. Using water wisely will ensure that we have enough water in dry years and for generations to come.
Water-use efficiency goals are established in accordance with WAC 246-290-830(6)(b).
Washington Water's company-wide water demand goal is an annual customer consumption of less than 117,300 gallons (or 0.36 acre feet) per year, per equivalent residential unit. Washington Water monitors demand and encourages conservation through a variety of resources. Washington Water's Customer Service Department alerts customers with unusually high consumption, and provides 13 months of consumption history on billing statements to all customers. See the conservation page for more information about how you can make a difference.
To control use of our groundwater sources, Washington Water established a supply goal to withdraw a maximum of 130,340 gallons (or 0.40 acre feet) per year, per equivalent residential unit. This goal is a measure of operational efficiency and adequate maintenance of pumping, treatment, and distribution systems. The difference between the supply and demand goals allows for a maximum of 10% total distribution system leakage use company-wide. Washington Water gauges and records monthly source production, and identifies treatment backwash and system flushing volumes to regularly assess supply-side conservation efficiencies. Washington Water also annually evaluates our systems' water main repair history and distribution system water losses to develop capital improvement projects for water main replacements. See the Capital Improvement Program page for current and recently completed main replacement projects.
