Bremerton Drinking Water Quality Excellent

The City of Bremerton Water Utility is pleased to provide you with its annual water quality and efficiency report. Bremerton is committed to safeguarding its surface and groundwater sources. This brochure is a summary of the test results for water provided to over 50,000 customers last year. It reflects the commitment of Water Utility employees to deliver you excellent quality water. Included are details about:
  • where your water comes from,
  • what it contains, and
  • how it compares to standards set by regulatory agencies.
Safe drinking water is essential. Citizens need to be well-informed to wisely utilize water resources and to support the improvements necessary to maintain high quality drinking water.

Protecting Our Water Supplies

Bremerton is fortunate to have well-protected water supplies. Surface water from the Union River headwaters and groundwater from production wells located in the Bremerton area provide the supply for Bremerton's water. All sources are managed in accordance with Washington State Department of Health requirements, Federal Environmental Protection Agency (EPA) regulations, and best management practices for water supply systems. Bremerton owns and protects the 3,000-acre watershed surrounding the Union River supply - this is a great value to our rate payers. Access to the watershed is secured, patrolled, and limited to water supply and forestry management activities. Each year the Washington State Department of Health inspects the surface supply. Groundwater wells are also safeguarded through efforts to protect critical areas around the wellheads. All water facilities are monitored and patrolled.



Bremerton's Water Needs Minimal Treatment

Bremerton's water system is operated and maintained by experienced personnel certified by the State. The Washington State Department of Health determined Bremerton's Union River water source to be of such good quality that the City is not required to install a filtration facility as long as all water quality, operational, and watershed protection requirements are met. Bremerton consistently meets these quality standards. Treatment of Bremerton's water currently consists of disinfection (chlorine and ultraviolet light) and corrosion control. Corrosion treatment increases the pH of water and is required to prevent Bremerton's water from leaching lead from customer's household plumbing. Sampling results confirm this treatment is successful in achieving corrosion control.

The City of Bremerton performs systematic flushing of the water distribution system. Customers are notified about flushing through newspaper ads, neighborhood signs, the City's website, e-News, and the Water Hotline (360-473-5490). Flushing is a process of sending a rapid flow of water through the mains to clean them. This helps to maintain water quality by removing naturally-occurring sediment. Flushing may cause temporary discoloration of your water. While this discoloration may be unpleasant, it is not harmful. If this happens, call the Water Hotline or visit Bremerton's website for instructions on flushing your service. If your water does not clear up after the flushing process, please call the Customer Response Line at 360-473-5920.

Water Quality Summary

Your drinking water is regularly tested in accordance with all federal and state regulations for over 50 substances in both the water sources and the distribution system. Last year the City of Bremerton conducted over 1,000 tests for the parameters listed below. Only those detected are listed in the water quality summary.

SAMPLING SCHEDULE
Compound
Frequency

Listed below are the few substances detected in Bremerton's water last year. All results meet protective standards set by federal and state agencies. Not listed are the substances that were tested but NOT detected. The amounts allowed in drinking water are so small, they are measured in parts per million or parts per billion. We have tried to make this report easy to understand; however, drinking water quality issues can be complex and technical. For additional water quality information, please call 360-473-5920.

Definitions

Action Level is the concentration of contaminant that, if exceeded, triggers treatment or other requirements a water system must follow. Ninety percent (90%) of all samples must be below this amount.
MCL (Maximum Contaminant Level) is the highest level of a contaminant that is allowed in drinking water.MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
MCLG (Maximum Contaminant Level Goal) is the level of a contaminant in drinking water below which no known or expected risk to health exists. MCLGs allow for a margin of safety.MRDL (Maximum Residual Disinfectant Level) is the highest level of a disinfectant allowed in water.
MRDLG (Maximum Residual Disinfectant Level Goal) is the level of a drinking water disinfectant below which no known or expected risk to health exists.
pCi/l stands for picocuries per liter. This is in parts per trillion.
ppb is parts per billion and is the same as a microgram per liter (ug/L) (equivalent to one penny in ,000,000).
ppm is parts per million and is the same as a milligram per liter (mg/L) (equivalent to one penny in ,000).
N/A means not applicable.
ND means the laboratory did not detect this substance.
NTU (Nephelometric Turbidity Unit) is the measurement of water clarity. Monitoring turbidity is a good indicator of water quality.
Treatment Technique is a required process intended to reduce the level of a contaminant. Bremerton's surface supply is shut off when turbidity increases above set points.


Information from EPA

Sources of both tap and bottled drinking water include rivers, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring substances such as minerals and radioactive materials. It also dissolves substances resulting from animal or human activity. Contaminants that may be present in source water are microbes; pesticides; herbicides; and radioactive, organic and inorganic chemicals. To ensure tap water is safe to drink, the Environmental Protection Agency (EPA) and the Washington State Board of Health regulate the amount of certain contaminants in public drinking water.

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 1-800-426-4791.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons, such as those 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 from infections. These people should seek advice about drinking water from their health care providers. EPA guidelines on appropriate means to lessen risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791. Please note that Cryptosporidium was not detected in Bremerton's source water last year and Bremerton's ultraviolet treatment inactivates Cryptosporidium.

EPA-Required Unregulated Contaminant Monitoring Rule

The City of Bremerton and other large water systems throughout the United States are required by the EPA to periodically test for substances that are currently not regulated. This requirement is called the Unregulated Contaminant Monitoring Rule and we are currently participating in Round 3 (UCMR 3). These parameters do not yet have drinking water standards and the results of this nationwide monitoring will help EPA decide which parameters should have a set health standard. In 2013, Bremerton sampled 28 substances. None of the organic parameters were detected, however, a few inorganic substances were detected at very low levels (parts per billion) as described below.

How to Use Water Wisely

Bremerton's water supplies are dependent on rainfall to fill the reservoir and feed underground aquifers. Wise water use is always recommended and your conservation efforts are important. Improve your home's water efficiency - use water wisely to save money and this remarkable resource.

Tackle the biggest water guzzlers first!
  • Install high efficiency low flow toilets.
  • Consider purchasing a water/energy efficient clothes washer/dishwasher.
  • Repair leaky toilets and faucets.
  • User water saving habits such as washing full loads only, turn off the faucet when you shave or brush your teeth, and take shorter showers.
  • Install low flow showerheads.
  • Look for the WaterSense label on new plumbing fixtures.
Nearly one-third of the water demand in the summer is for irrigation.
  • Water late in the evening or early in the morning.
  • Consider drought tolerant plants or native plants in your landscape.
  • Use soaker hoses or install drip irrigation.
  • Repair broken irrigation system sprinkler heads.
  • Water lawns no more than 1 inch per week using a shallow can to measure.
  • Install a rainwater collection barrel.
  • Wash your car in a commercial car wash that recycles.
