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. This CCR outlines where your drinking water comes from, how it is treated and test result analysis on the quality of Hoopa Valley's Public Water System. This report is a snapshot of your water quality. Included are details about where your water comes from, what it contains, and how it compares to standards set by regulatory agencies. We are committed to providing you with information because informed customers are our best allies. 

The Hoopa Valley Public Utilities District (HVPUD) is dedicated to ensuring the delivery of safe and reliable drinking water to our community. We recognize the critical importance of clean water to the health and well-being of community, and we are fully committed to maintaining the highest standards of water quality as mandated by the Environmental Protection Agency (EPA). Our ongoing efforts include rigorous testing and monitoring of our water supply to meet and exceed all federal drinking water standards. We employ state-of-the-art technology and adhere to best practices in water treatment to safeguard against any contaminants. 

This past year, HVPUD has secured over $5 Million Dollars in funding for infrastructure and planning investments, which includes replacement of the Campbell Tanks (Cherry Flat and Upper Telescope). This coming year, we will finalize designs and begin construction on the Norton and Hostler Tanks. HVPUD is honored to serve the Hoopa Valley community and is dedicated to continuous improvement in all aspects of our water service. Thank you for your trust and support as we strive to provide the highest quality drinking water. 

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 Environmental Protection Agency (EPA) and Centers for Disease Control (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 Environmental Protection Agency'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 including: 

  • Microbial contaminants, such as viruses and bacteria, that 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, urban stormwater runoff, and residential uses; 
  • 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; 
  • Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities. 

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

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. Unless otherwise noted, the data presented in this table is from testing done in the calendar year of the report. The EPA or the State requires monitoring for certain contaminants less than once per year because the concentrations of these contaminants do not change frequently.

Special Statements 

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. You share the responsibility for protecting yourself and your family from the lead in your home plumbing. You can take responsibility by identifying and removing lead materials within your home plumbing and taking steps to reduce your family's risk. 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. If you are concerned about lead in your water and wish to have your water tested, contact your water utility. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at http://www.epa.gov/safewater/lead

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. 

Per- and Polyfluoroalkyl Substances (PFAS) Monitoring 

In April 2024, EPA announced a final National Primary Drinking Water Regulation (NPDWR) for six PFAS compounds. Under the rule, we are required to conduct initial monitoring by 2027 and comply with maximum contaminant levels (MCLs) by 2029. Last year, our water system evaluated for the presence of twenty-five PFAS compounds, including the six compounds involved in the new rule. No PFAS compounds were detected in your drinking water. PFAS are a group of thousands of synthetic chemicals that have been in use since the 1940s. PFAS have been found in a wide array of consumer and industrial products and as an ingredient in firefighting foam. Current scientific research has shown links between exposure to some PFAS chemicals and adverse health outcomes. Drinking water may be impacted in communities where these chemicals have contaminated the water supply. You can find more information about EPA's actions to address PFAS in drinking water and links to informational resources here: www.epa.gov/pfas 

Additional Information for Unregulated Contaminant Monitoring Rule (UCMR) 

Our water system has sampled for a series of unregulated contaminants. Unregulated contaminants are those that don't yet have a drinking water standard set by EPA. The purpose of monitoring for these contaminants is to help EPA decide whether the contaminants should have a standard. As our customers, you have a right to know that these data are available. 

Service Line Inventory for Systems with All Non-Lead 

Hoopa Valley-Wide System was required to complete an inventory of service line materials to determine whether any service lines connected to the distribution system are made of lead material. 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, please contact us for more information. 

Microbiological Testing 

We are required to test your water regularly for signs of microbial contamination. Positive test results could lead to follow-up investigations called assessments and potentially the issuance of public health advisories. Assessments could lead to required corrective actions. The information below summarizes the results of those tests.

Significant Deficiencies 

Sanitary deficiencies are defects in a water system's infrastructure, design, operation, maintenance, or management that cause, or may cause interruptions to the "multiple barrier" protection system and adversely affect the system's ability to produce safe and reliable drinking water in adequate quantities. The following is a listing of significant deficiencies that have yet to be corrected. Your public water system is still working to correct these deficiencies and interim milestones are shown, as applicable. 

1. Deficiency Title: Telescope Tank (25,000-gallons), Upper Community Rd (Shop Ctr) Tank, and N Agency Tank 

  • Date Identified / Overall Due Date: (Not explicitly provided in text)
  • Deficiency Description: These tanks have several potential openings for contaminants to enter the water supply: holes in the redwood; lack of seal between the roof and shell (wall); unsealed and overlapping covers on the roof hatch; unscreened, shrouded and covered vents, etc. The roofs on several of these tanks could not be accessed during the survey due to safety concerns. These tanks are targeted for replacement, but replacement is not immediate. (See Photos 24 and 25, 30 and 31, and 36-38.) 
  • Corrective Action Plan: Safely and thoroughly inspect the tanks. Any direct openings to the tank's interior need to be plugged or, at the very least, screened, and shrouded. The repairs can be temporary due to the future replacement of the tanks but need to be completed to prevent immediate routes of contamination. 
  • Milestones:
    • Milestone completed by 5/28/2021: Screening is placed over holes of the 3 redwood tanks. 
    • Milestone completed by 5/16/2024: Tribe applied for EPA DWTSA funding to replace Telescope Tank in FY2024. Agency Tank replacement in progress. 
    • Milestone completed by 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. 

2. Deficiency Title: No Cross Connection Control Program 

  • Date Identified: 10/17/2025 | Overall Due Date: 12/31/2026 
  • Deficiency Description: The PWS has a draft cross-connection control ordinance that has not been approved by the Tribal council. The PWS has several commercial customers which may have hazards that require backflow prevention. This is an ongoing deficiency identified in the previous sanitary survey. 
  • Corrective Action Plan: After final review of the cross-connection control plan, it should be presented to the Utility District's board of directors. High risk service connections should be equipped with testable backflow prevention assemblies and tested on an annual basis by a certified tester. Assemblies that fail the test must be repaired within the timeframe required by the plumbing code to ensure that the assemblies are in working condition and capable of preventing backflow.
