Hoopa Valley Public Utilities District (HVPUD) P.O. Box 656, Hoopa, CA 95546 (530) 625-4543 | Fax: (530) 625-4112 | gm@hoopavalleypud.com

The Hoopa Valley Public Utilities District (HVPUD) presents this Consumer Confidence Report (CCR) to all customers in accordance with 40 CFR 141. HVPUD is committed to providing safe drinking water to this community by having qualified personnel who are certified by the California State Water Resources Control Board to operate, maintain, repair and manage our water treatment plants and the distribution system within the Hoopa Valley Indian Reservation. We are committed to providing you with information because informed customers are our best allies.

HVPUD Updates & Commitment

The Hoopa Valley Public Utilities District is dedicated to ensuring the delivery of safe and reliable drinking water to our community. Our ongoing efforts include rigorous testing and monitoring of our water supply to meet and exceed all federal drinking water standards.

Infrastructure Investments:

This past year, HVPUD has secured over $4 Million Dollars in funding for infrastructure and planning investments, which includes:

  • Storage Tank Replacement: Replacement of the Agency and Soctish Water Storage Tanks.
  • Future Replacements: Releasing Request for Proposals to replace the Upper Telescope Tank and the Cherry Flat water tanks to improve water quality in those areas.
  • System Monitoring: Completed a radio frequency study and SCADA study to improve telemetry and control management.

Do I need to take special precautions?

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer 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. The EPA and CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Water Drinking Hotline (800-426-4791).

Where does my water come from?

Your water comes from 2 surface water sources, the Trinity River and Campbell Creek.

Why are there contaminants in my 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 (800-426-4791).

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.

Water Quality Table

The table below lists all of the drinking water contaminants detected during the calendar year of this report. The presence of contaminants in the water does not necessarily indicate that the water poses a health risk.

Special Statements

Service Line Inventory We determined that all service lines at Hoopa Valley-Wide System are made of non-lead materials. The service line inventory is available upon request.

Educational Statement for Lead 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. Hoopa Valley-Wide System is responsible for providing high quality drinking water and removing lead pipes, but cannot control the variety of materials used in plumbing components in your home. Before drinking tap water, flush your pipes for several minutes by running your tap, taking a shower, doing laundry or a load of dishes. You can also use a filter certified by an American National Standards Institute accredited certifier to reduce lead in drinking water.

Per- and Polyfluoroalkyl Substances (PFAS) Monitoring In April 2024, EPA announced a final National Primary Drinking Water Regulation (NPDWR) for six PFAS compounds. Last year, our water system participated in a voluntary sampling project that evaluated for the presence of twenty-five PFAS compounds. No PFAS compounds were detected in your drinking water.

Unregulated Contaminant Monitoring Rule (UCMR) Our water system has sampled for a series of unregulated contaminants to help EPA decide whether the contaminants should have a standard.

Microbiological Testing

We are required to test your water regularly for signs of microbial contamination.

Significant Deficiencies

Sanitary deficiencies are defects in a water system's infrastructure or management that may cause interruptions to the protection system. The following is a listing of significant deficiencies that have yet to be corrected.

  • Deficiency Title: Telescope Tank, Upper Community Rd Tank, and N Agency Tank
    • Due Date: 3/31/2023
    • Description: These tanks have several potential openings for contaminants to enter the water supply: holes in the redwood; lack of seal between roof and shell; unsealed and overlapping covers; unscreened vents.
    • Corrective Action: Safely and thoroughly inspect the tanks. Direct openings need to be plugged or screened.
    • Progress:
      • 5/16/2024: Tribe applied for EPA DWTSA funding to replace Telescope Tank in FY2024. Agency Tank replacement in progress.
      • 10/30/2024: Agency Tank replacement completed. Funding obtained to replace Telescope Tank. Tribe applied for EPA DWTSA funding to replace Upper Shopping Center Tank in FY2025.
