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 $5 Million Dollars in funding for infrastructure and planning investments, which includes:
- Upgrades to the Campbell Creek Water Treatment Plant and Sedimentation Basin.
- Replacement of the Agency and Soctish redwood tanks with steel bolted tanks.
- Replacement and upgrade of four (4) more tanks in the coming years.
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 Education Statements
Per-and Polyfluoroalkyl Substances (PFAS) Monitoring Last year, your water system participated in a voluntary sampling project that evaluated for the presence of twenty-five PFAS compounds. No PFAS constituents were detected in your drinking water.
- PFAS are a group of thousands of synthetic chemicals that have been in use since the 1940s.
- EPA finalized a National Primary Drinking Water Regulation in April 2024 that includes 6 PFAS. Community and non-transient public water systems will have until April 2027 to complete initial monitoring and April 2029 for MCL compliance.
Additional Information for Lead 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. PWS system is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at 1-800-426-4791 or at http://www.epa.gov/your-drinking-water/basic-information-about-lead-drinking-water.
Additional Information for Turbidity Turbidity is a measure of the clarity of water. We monitor this as an indicator of the effectiveness of our filtration system.
Microbiological Testing
We are required to test your water regularly for signs of microbial contamination.
| Calendar Year | Sampling Requirements | Sampling Conducted (months) | Total E.coli Positive | Assessment Triggers | Assessments Conducted |
| 2023 | 4 Samples due monthly | 12 out of 12 | 0 | 0 | 0 |
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: No Backup power for the Pumping Facilities
- Due Date: 1/1/2023
- Description: None of the pumping facilities have backup power supplies.
- Corrective Action Plan: Install standby power with automatic power transfers at each pumping facility. USEPA Region 9 has provided funding.
- Progress: A contract for generators has been issued with a vendor, but securing them is delayed; delivery expected in October 2021.
- 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: Tribe applied for EPA DWTSA funding to replace Telescope Tank in FY2024. Agency Tank replacement in progress (Note dated 5/16/2024).
