Water Quality Report 2022

 

Why am I receiving this report?

In 1999, the Federal Government re-authorized the Safe Drinking Water Act of 1996 which requires all public water utilities and companies to provide annual drinking water quality reports to their customers. Accordingly, Point Roberts Water District No. 4 is pleased to provide you with this report.

.

Where does my drinking water come from?

The District purchases its water from the Metro Vancouver Water District, which draws its water from three protected source lakes: Seymour, Capilano, and Coquitlam; with Point Roberts’ main water supply coming from the Seymour facility.

The water to Point Roberts is drawn from the Pebble Hill Reservoir located in Tsawwassen, B.C. and distributed through our own water distribution system to your tap.

What’s in my drinking water?

Point Roberts Water District No. 4 and the Metro Vancouver Water District routinely monitor for contaminants and constituents in your drinking water in accordance with Federal and State Laws. For the year 2022, we conducted fifty-two (52) tests for bacteriological analysis. All results tested satisfactory.

Additionally, the Metro Vancouver Water District conducted tests for drinking water contaminants see: http://www.metrovancouver.org/services/water/WaterPublications/water-quality-annual-report-Volume-2-2022.pdf

The Seymour water source from Vancouver is currently filtered. Chlorination treatment is added to protect against giardia and bacteria. Corrosion control treatment is done at Seymour and Coquitlam. Since surface water tends to have a low pH, soda ash and/or lime are added to increase the pH to 7 or above.

All drinking water, including bottled water, may reasonably be expected to contain at least trace amounts of some contaminants. It is important to remember that the presence of contaminants does not necessarily pose a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (800-426-4791).

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-comprised persons such as persons 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/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are also available from the Safe Drinking Water Hotline.

Contaminants that may be present in source water before it is treated include:

  • · Microbial contaminants, such as viruses 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 and residential uses.
  • · Radioactive contaminants, which are naturally occurring.
  • · 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 stormwater runoff and septic systems.

  • In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the number of certain contaminants in water provided by public drinking water systems. We treat our water according to EPA regulations. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

    Terms and Definitions

    • Maximum Contaminant Level (MCL): the highest level of a contaminant that is allowed in drinking water

    • Action Level (AL): the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow

    • Million Fibers per Liter (MFL): a measure of the presence of asbestos fibers that are no longer than 10 micrometers

    • ppm: parts per million or milligrams per liter

    • Bq/l: Becquerels per liter (Bq/l))

    • Water Quality Data

Facts About Tested Contaminants

Coliform Bacteria: Coliforms are common in the environment and generally are not harmful. The presence of these bacteria in drinking water, however, generally is a result of a problem with water treatment or the pipes which distribute water and indicate that the water may be contaminated with organisms that can cause disease.

The Point Roberts Water District No. 4 did fifty-two (52) coli form bacteria tests for the year 2022. The Washington State Department of Health determines the minimum number of samples required based on the population that is served. Two (2) samples per month are required by the State during the months of January through May and from September through December; however, the Point Roberts Water District completed four (4) samples during this time period.

Nitrates: Nitrates in drinking water at levels about 10 ppm is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask for advice from your health care provider.

Lead: Infants and children who drink water containing lead more than the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.

Copper: Copper is an essential nutrient, but some people who drink water containing copper more than the action level over a relatively short amount of time could experience gastrointestinal distress. Some people who drink water containing copper more than the action level over many years could suffer liver or kidney damage. People with Wilson’s disease should consult their personal physician.

Alpha/Radiation: Some people who drink water containing levels of Alpha/Radiation more than the MCL over many years may have an increased risk of developing cancer.

TTHM (Total Trihalomethanes): Some people who drink water containing trihalomethanes more than the MCL over many years may experience problems with their liver, kidneys, or central nervous systems and may have an increased risk of getting cancer.

Asbestos: Some people, who drink water containing asbestos more than the MCL over many years, may have an increased risk of developing intestinal polyps.

Arsenic: Some people, who drink water containing arsenic more than the MCL over many years, may have decreased longevity, blood effects, dermal and nervous system toxicity effects.

Water Use Efficiency Rule
The State Department of Health has been directed to adopt an enforceable WUE program intended to achieve a high level of stewardship among all water suppliers, contribute to long-term supply reliability and public health concerns, and insure efficient operation and management of water systems. Below are the measures that Point Roberts Water District has already implemented and our goals for 2020.

Goal –Setting Information:
Total Usage Reduction Goal: 2% total usage reduction by year 2020 achieved by a combination of demand side and supply side measures.
Demand Side Goal (The Customer): Reducing from an average of 111 gallons per connection per day to an average of 95 gallons per connection per day.

Point Roberts Water District Goals:
Measures to achieve Supply Side Goal: The District has replaced 6000 lineal feet of water main in known leakage areas. Additional water main replacement will continue in problem areas.
The regular scheduled water rate surveys encourage conservation along with staff working with customer water use evaluations and helping with water loss in the home.
