2017 Annual Drinking Water Quality Report

Vera Water and Power pumped 3.38 billion gallons of water to its customers in 2017. Of the 3.38 billion gallons pumped, we reported a 10.1 percent leakage.

Vera is required under the State Water Use Efficiency Rule to sustain an average loss of 10 percent or less for three years running. We did not meet the requirement this year. We work to maintain our water system with a strong leak detection program and aggressive hydrant use metering policies to reduce the loss of water each year.

Water loss also results during construction in the district and from accidental digging into water lines. Vera’s conservation requirements make it essential that our leaks and construction dig-in repairs receive top priority. Our goal is to preserve an adequate supply of safe, reliable drinking water for our future generations.

The Washington State Department of Health has mandatory health-related standards for public drinking water. Hundreds of tests for contaminants, chemical, metals, and compounds were run on our drinking to ensure your safety. In every case, our drinking water passed safety tests with flying colors.

Test: Microbiology

300 tests were taken during this reporting period. Zero sample sites had total coliform present. Zero sample sites had fecal coliform and E. Coli present. (25 samples monthly)

Results: No constituents detected at wells for Total Coliform Bacteria, Fecal Coliform, and E. Coli.

Test: Inorganic chemicals

29 Inorganic Chemicals have been tested for in 2016 at Well No. 4

Results: Action levels not exceeded.

Test: Nitrates

Measured in ppm 10 MCL and MCLG

Results: Below 10

Highest detected levels at pump stations

Measure 2.56 0.65 1.24 2.82 1.32 1.37 N/A 0.78 0.74 1.22

Likely source of contamination: Runoff from fertilizer use, leaching from septic tanks, sewage, erosion or natural deposits.

Test: Synthetic Organic Compounds

85 Synthetic Organic Chemicals have been tested for in 2016.

Results: No constituents detected.

Likely source of contamination: Herbicides, Pesticides

Test: Volatile Organic Compound

62 Volatile Organic Chemicals have been tested for in 2017 at Well No. 5.

Results: Action levels not exceeded.

Likely source of contamination: Erosions of natural deposits

Test: Lead and Copper

30 homes were tested in 2016 for Lead and Copper, which is regulated at the customer’s tap every three years.

Results: Action levels not exceeded.

Likely source of contamination: Leaching or corrosion of household plumbing systems.

TTHMs (Total Trihalomethanes)

HAA5 (Haloacetic Acids)

Results: No exceedances

Lead in drinking water

In Washington State, lead in drinking water comes primarily from materials and components used in household plumbing. The more time water has been sitting in pipes, the more dissolved metals, such as lead, it may contain. Elevated levels of lead can cause serious health problems, especially in pregnant women and young children. To help reduce potential exposure to lead, flush tap water that has not been used for six hours or more through the tap until it is noticeably colder before using the water for drinking, cooking or cleaning. Use cold water for drinking, cooking and making baby formula, since hot water is more likely to contain higher levels of lead. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in your drinking water is available from EPA’s Safe Drinking Water Hotline at 800-426-4791 or at www.epa.gov/safewater/lead.
