Can You Drink Tap Water in Federal Way?
Yes, Federal Way's tap water is generally considered safe to drink as Federal Way 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, Federal Way's water utility, Lakehaven Water and Sewer District, 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 Lakehaven Water and Sewer District 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 Federal Way Tap Water
The most recent publicly available numbers for measured contaminant levels in Federal Way 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 Federal Way's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.
Federal Way Tap Water Safe Drinking Water Act Violation History - Prior 10 Years
Below is a ten year history of violations for the water system named Lakehaven Water and Sewer District for Federal Way in Washington. For more details please see the "What do these Violations Mean?" section below.
Is there Lead in Federal Way Water?
Based on the EPA’s ECHO Database, 90% of the samples taken from the Federal Way water system, Lakehaven Water and Sewer District, between sample start date and sample end date, were at or below, 0.0037 mg/L of lead in Federal Way water. This is 24.7% of the 0.015 mg/L action level. This means 10% of the samples taken from Federal Way contained more lead.
While Federal Way water testing may have found 0.0037 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 Federal Way 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 no military bases near Federal Way 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 Federal Way 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
- Maximum contaminant levels (MCLs) - maximum allowed contaminant level was exceeded.
- Maximum residual disinfectant levels (MRDLs) - maximum allowed disinfectant level was exceeded.
- Other violations (Other) - the exact required process to reduce the amounts of contaminants in drinking water was not followed.
Non-Health Based Violations
- 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.
- 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.
- Other violations (Other) - miscellaneous violations, such as failure to issue annual consumer confidence reports or maintain required records.

Multiple Water Sources
Lakehaven’s water supply comes from two sources:
The Regional Water Supply System(“RWSS”) is from the protected Green River watershed that originates in the foothills of the Cascade Mountains in South King County. The RWSS at times may include water pumped from wells located on the North Fork of the Green River, also within the protected watershed. Water from the Green River watershed is diverted below Howard Hanson Dam to the new Green River Filtration Facility (where it is
treated and filtered) and then into a
Lakehaven also has 25 active wells located within its water district boundary. These wells pump from three aquifer producing geologic layers, confined locally deep below the Federal Way area, and are dependent on local precipitation to recharge and store water.
The drinking water from the RWSS is an interruptible source of water for Lakehaven and is intended to supplement our groundwater supply. RWSS water availability can be interrupted due to drought conditions, low river flow volumes in the Green River, or other water quality issues. Lakehaven will continue to utilize water from the RWSS as it is available to better manage our water resources and help reduce the demand on our existing groundwater system.

Keeping Your Water Safe
Water System Security
To assure that your drinking water supply remains safe and secure, Lakehaven Water & Sewer District (“District”) facilities are equipped with intrusion security systems to protect them from unauthorized entry, vandalism and more. Water facility security systems alert staff 24/7 of any alarms in order to keep our drinking water supply safe and secure. In 2020, the District completed its Risk and Resilience Assessment (RRA) and Emergency Response Plan (ERP) to meet its compliance with the requirements of the 2018 American Water Infrastructure Act (AWIA). The purpose of the RRA and ERP was to review the District’s current water system security procedures and equipment, and identify areas for improvements to help the District in responding to emergencies and natural hazards.
Wellhead Protection Program
Preventing pollution is the first priority in protecting public health and our groundwater supply. The District’s Wellhead Protection Program intends to identify potential areas where surface water can more readily contribute to the storage of water in our underground aquifer systems and affect the quality of water pumped from our wells. Through this program, the District continues to develop appropriate management plans to protect our water quality should a surface contaminant spill occur. In 2020, Lakehaven staff completed a biennial land use inventory update of our Wellhead Protection Areas and a review of potential contaminate sources in accordance with the Washington Administrative Code
For more information on the Wellhead Protection Program or to report spills, water pollution or contamination, call Darlene LeMaster, Water Operations Analyst at
Testing Your Water
If you wish to have the tap water in your home tested, please contact a state certified lab such as Water Management Laboratories, 1515 80th St. E., Tacoma, (253)

Water Quality Treatments
Arsenic
Arsenic is a regulated primary inorganic contaminant found in waters of Western Washington and is typically present due to natural weathering and dissolution of arsenic bearing rocks and minerals.
Only two of the District’s 25 wells produce groundwater with a concentration of arsenic that slightly exceeds the Environmental Protection Agency (EPA) Maximum Contaminant Level (MCL) of 10 parts per billion. When these wells operate, both have special water treatment systems that reduce the arsenic concentration to very low levels that meet safe drinking water standards.
During 2020, the water produced from these wells represented only 0.3% of all our drinking water. Nevertheless, when operating these wells, the treated water could still contain some very low “harmless” levels of naturally present arsenic.
Iron and Manganese
The EPA classifies high concentrations of naturally occurring iron and manganese in drinking water as secondary inorganic contaminants. In drinking water, iron and manganese can cause aesthetic issues such as taste, odor, or staining of plumbing fixtures when concentrations exceed the MCL. Because
of this, groundwater pumped from fourteen District wells receives treatment for the removal of iron and manganese by oxidation/filtration before the water enters into our distribution system.
Chlorine Disinfection
As an important component of our water treatment program, the Washington State Department of Health requires the addition of chlorine to our drinking water as a disinfectant to make sure that our water remains biologically safe for our customers to use.
Lakehaven uses chlorine gas to disinfect its water sources and we continually monitor the concentrations so that we do not exceed federal safe drinking water levels (maximum residual disinfection level is 4.0 ppm). The free chlorine residuals in
our system ranges between approximately 0.5 and 1.0 ppm. During 2020, the average chlorine concentration in our drinking water was 0.91 parts per million (ppm). Just as water is essential to life, chlorine is considered essential to maintaining a safe water supply.
This is one of the District’s water filtration plants that removes natural occurring minerals (arsenic, iron and manganese) and adjusts the pH of the groundwater pumped from nearby wells.

pH Adjustment with Sodium Hydroxide
Sodium Hydroxide (caustic soda) is added to the water supply to raise pH levels. By raising the pH levels (ie: less acidic), the water becomes less corrosive on plumbing and reduces the amount of lead and copper that can dissolve into drinking water.
Fluoride
The Regional Water Supply System (RWSS) is a partnership with the Cities of Tacoma, Kent and Covington. This supply is surface water from the Green River Watershed and is disinfected with chlorine, fluoridated and pH- adjusted with sodium hydroxide. In addition, ozone is used to control taste and odor. This report includes the RWSS’s water quality data in our system.
Fluoride is a natural element found in the earth’s crust and is commonly found in various concentrations in raw water supplies (both surface and groundwater) and at low levels, fluoride has been known to prevent dental cavities.
The natural fluoride levels in Lakehaven Water & Sewer District’s groundwater is considered lower than optimal for helping to prevent dental decay. The drinking water received from the Regional Water Supply System (RWSS) is treated with fluoride by the City of Tacoma. RWSS water contains fluoride concentrations equal to the US Public Health Service (USPHS) suggested range in drinking water of about
0.70 part per million (ppm). However, blending the District’s groundwater supplies with the RWSS supply can dilute of fluoride in some locations below the desirable therapeutic range. Lakehaven staff who monitor fluoride levels in our distribution system reported the highest level detected and average concentration in 2020 was 0.93 ppm and 0.47 ppm respectively.
If you have children on fluoride supplemental treatment, you may want to consult with your dentist or pediatrician about the variable fluoride concentrations that may be present in your drinking water. More information on fluoride can be found at the CDC at http://www.cdc.gov/fluoridation/faqs.

Other Water Quality Topics
Important Information for Your Health
Some people may be more vulnerable to contaminants in drinking water than the general population.
Cryptosporidium
Cryptosporidium is a microscopic organism found in open surface water supplies that, when ingested, can result in diarrhea, fever and other gastrointestinal symptoms. Water quality monitoring by Tacoma Water show levels of cryptosporidium remains low in the Green River water supply (The District’s “RWSS” water source) and Tacoma has not experienced any health issues with this organism. Federal and state regulations require us to treat Green River Water (RWSS) for Cryptosporidium. We remove any cryptosporidium that may be present effectively with filtration.
Water Hardness
Lakehaven’s wells (ground water) vary greatly in hardness. Hard water may cause scale buildup in cooking pans, sinks, and water heaters, and may require using more soap to form a lather. Many newer dishwashers, home filtration systems, coffee makers have settings to adjust for water hardness.
A water’s hardness is dependent upon the levels of two naturally occurring soluble minerals – calcium and magnesium. Of the wells utilized in 2020, water hardness ranged from 26 mg/L to 130 mg/L. The year’s average calcium/magnesium level was 88.1 mg/L (moderately hard). Blending the District’s groundwater supply (wells) with the RWSS (surface water) lessened the water hardness. The

Lead in Drinking Water
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.
Lakehaven Water & Sewer District is responsible for providing high quality drinking water, but cannot control the variety of materials used in private plumbing components. Lakehaven has never installed lead goosenecks on any water service lines or used lead piping in our distribution system. The District is consistent with regulatory guidelines (EPA Lead
- Copper Rule) and controls the corrosiveness of our water supply (corrosion control occurs primarily by controlling the pH of the water supply).
Even though our source water has not been found to have detectable levels of lead, private plumbing installed in residences built from 1983 to 1986 with copper pipe and lead solder are considered by the EPA to have a higher risk for lead and copper leaching. These homes are used by the District to test tap water samples for regulatory testing and reporting. The District’s local corrosion control treatment methods show that lead and copper contamination is abated in the identified
these corrosion control methods has been confirmed by many years of water quality monitoring.
Anyone with lead solder and copper plumbing who still have concerns about lead or other metals in their drinking water, can further reduce their chance of exposure by flushing standing (stagnant) water in their pipes before using it. Typically, the best way to tell if the water from outside the house has reached your tap is to flush long enough to feel a colder, stable temperature difference during this short flushing period (usually 45 seconds to one minute).
You can used this flushed water for watering plants, washing dishes or general cleaning. Only use water from the
The most common problem is brass or chrome plated brass faucets and fixtures that can leach lead into water, especially hot water. Until seven years ago, the legal limit for “lead free” pipes was up to 8% lead. As of January 1, 2014, all newly installed water faucets, fixtures, pipes, and fittings must meet new
of lead allowed to 0.25%. These requirements do not apply to existing fixtures, such as those found in many older homes.
Lead and Copper Sampling
If your home was built between 1983 and 1986 and you’d like to participate in our regulatory testing process, please contact John Vindivich, Water Operations Operator III at jvindivich@lakehaven.org. The next EPA Lead and Copper Testing and Reporting will occur in 2022. Additional 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/safewater/lead.

2020 Water Quality Monitoring Results
There is no such thing as naturally pure water. In nature, all water contains some impurities. As water flows in streams, sits in lakes, and filters through layers of soil and rock in the ground, it dissolves or absorbs the substances that it touches.
Some of these substances are harmless. In fact, some people prefer mineral water precisely because minerals (which are chemical substances) give water an appealing taste. However, at certain levels minerals, just like
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 Environmental Protection Agency’s Safe Drinking Water Hotline at (800)
Lakehaven Water & Sewer District tests our drinking water for 35 regulated and unregulated inorganic contaminants (IOCs) and 16 synthetic organic contaminants (SOCs). The chemicals shown in the summary table of this report were the only regulated IOCs detected
in samples collected during tests performed in the past five years. There have been no SOC’s detected in our drinking water.
Lakehaven Water & Sewer District tests for other substances and microscopic organisms in our drinking water for which no mandatory testing standards have been set. Many substances and microscopic organisms found in water may be a concern if they occur at high concentrations. Because of this, the District has been monitoring heterotrophic bacteria in our drinking water for many years. The heterotrophic plate count (HPC test) measures a broad group of microorganisms

that are commonly found in drinking water as a tool to track the concentration of these “background” microorganisms in our distribution system. The EPA has determined that a well- operated water system with a
of less than 500 colonies per milliliter (ml). A sample with a count higher than 500 Colony- Forming Units (CFU) per milliliter is considered undesirable and should be investigated to determine the cause. During 2020, the District sampled and tested our drinking water throughout the distribution system for HPCs using a state certified laboratory and government approved techniques. The highest concentration of these heterotrophic microorganisms detected in our water system was 56 CFUs per milliliter. To make
sure these organisms remain in low concentrations, testing will continue as will our communication with our customers.
The following tables show the results of water quality analyses on “treated” (water quality treatments) source water during 2020. Every regulated contaminant that was “detected” in our drinking water, even in the most miniscule traces, is listed in the table along with unregulated, secondary, and physical and chemical parameters. A host of additional substances were tested in 2020, but because they were not detected they are not shown on the table.
Lakehaven Water & Sewer District is pleased to report that there were no EPA or State drinking water violations for the District in the year 2020. Additional information on all data can be obtained by contacting Tim Osborne, Water Operations Manager, at

Washington State Department of Health Monitoring Waivers
Lakehaven Water & Sewer District applied for and received special monitoring waivers for certain targeted wells for 2020 from the Washington State Department of Health. These special monitoring waivers were granted for the purpose of reducing unnecessary sampling and testing of raw groundwater for analysis of organic and inorganic chemicals and the more common insecticides, herbicides, and pesticides. The District received these waivers because previous laboratory tests show no detection of these contaminants and groundwater from these wells has a very low susceptibility to contamination.

Water Quality Monitoring Results Footnotes
-
The fourth Unregulated Contaminant Monitoring Rule (UCMR4) was published on December 20, 2016. UCMR4 requires monitoring for 30 chemical contaminants (cyanotoxins, metals, pesticides, disinfection byproducts, alcohols, and semivolatile organic chemicals) between 2018 and 2020 using analytical methods developed by EPA and consensus organizations. EPA announced the proposed fifth Unregulated Contaminant
Monitoring Rule (UCMR 5) for Public Water Systems for 2022. The proposed
UCMR 5 requires monitoring for 29 per- and polyfluoroalkyl substances
(PFAS) and lithium in drinking water. UCMR 5 proposal includes monitoring for six PFAS that were part of UCMR 3. The proposal would requirepre-sampling preparations in 2022, sample collection from2023-2025, and reporting of final results through 2026. UCMR provides a basis for future regulatory actions to protect public health. - Fluoride from source water samples measures the level of fluoride as a natural mineral deposit (Lakehaven Groundwater). Fluoride for distribution system is a measurement of added fluoride as a treatment of the drinking water (RWSS Green River & North Fork)
- The distribution system is a blend of both groundwater (from wells) and/or surface water (from the RWSS Green River & North Fork).
- The Lead and Copper Rule (LCR) is a treatment technique rule. Instead
of setting a maximum contaminant level (MCL) for lead or copper, the rule requires public water systems to take certain actions to minimize lead and copper in drinking water. These actions reduce water corrosivity and prevent
the leaching of these metals from the premise plumbing and drinking water distribution system components. If those actions are not sufficient, the rule prescribes water quality parameter monitoring, corrosion control treatment, source water monitoring and treatment, of service lines and public education. Utilities must ensure that water from the customer’s tap does not exceed the “action level” for lead (15 ppb) in at least 90 percent of the homes sampled.
- Turbidity and Nickel are EPA regulated secondary analytes. They do not pose a health risk but may impair taste, odor and/or clarity of drinking water.
- Concentrations of EPA regulated analytes may not exceed the maximum contaminant level (MCL).
-
The heterotrophic plate count (HPC test) measures a broad group of
micro-organisms that are commonly found in drinking water as a tool to track the concentration of these microorganisms in our distribution system. The EPA has determined that awell-operated water system with awell-maintained distribution system should have HPC populations of less than 500 colonies per milliliter (ml). A sample with a count higher than 500Colony-Forming Units (CFU) per milliliter is considered undesirable and should be investigated to determine the cause. - During 2020, 2,434 water samples were collected and tested for bacteriological contamination at sample stations in the distribution system, water storage tanks, source wells, and the RWSS. Of the 2,434 water samples collected, none tested positive for coliform bacteria.

Water Use Efficiency (WUE)
12-Month Performance Reporting Period: January 1, 2020 to December 31, 2020
In 2003, the Washington State Legislature passed ESSHB 1338, better known as the Municipal Water Law (MWL), to address the increasing demand on our state’s water resources. This law establishes that all municipal water suppliers (MWS) must use water more efficiently in exchange for water right certainty and flexibility to help them meet future demand. The Water Use Efficiency Rule is part of this law and requires municipal water suppliers to report their goals and progress each year.
The WUE rule requires water systems to engage their customers and interested public in a public forum setting when establishing their water efficiency goals. It ensures customers and the public can provide input on the decisions made by the governing body. It also helps the public understand the need to use water more efficiently and to educate them on how they can help the water system achieve conservation goals.

Water Main Flushing
Distribution system flushing is one of the most powerful tools Lakehaven Water & Sewer District uses to maintain good water quality in the distribution system. Annual flushing of District water mains scours and removes mineral scale, silt and trapped stagnant water that can contribute to customer complaints of poor water quality.
In 2020, Water Operations Maintenance staff flushed over 100 miles of water main within our service district. The simple operation of “Unidirectional Flushing” involves flushing isolated sections of water mains in one direction beginning at a source
like a well site or a storage tank and continuing the operation downstream of each water main section until all of the system is completely flushed.
The District’s goal is to flush the entire water service area every three years. Staff sends out notification letters to those customers due for main flushing.
The letters also contain helpful information and contact information for the Water Operations Department. Signs are posted at the streets that will be flushed during the next week of scheduled flushing. For more information on water main flushing, please visit our website http://www.
Dechlorinating diffusers are attached to the fire hydrant during main flushing.

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.
