Water Quality Summary
Tap water quality in Vancouver, Washington (98668) receives an overall grade of C (Fair) with a score of 56 out of 100, based on analysis of EPA compliance data, contaminant testing, and violation history. This is 20 points below the Washington state average of 76. Compared to the national average (75), this area scores significantly lower. The area is served by 5 water systems providing water to approximately 377,172 people, using surface water and groundwater sources. Testing has found elevated levels of Lead, Copper that warrant attention. Notably, 2 PFAS compounds exceed EPA limits — a significant concern given the persistent nature of these chemicals. Over the past 5 years, water systems here have accumulated 6 violations, including 2 health-based violations.
A score of 56/100 indicates fair water quality in Vancouver, WA. While the water meets minimum federal standards, there are noteworthy concerns — either elevated contaminant levels approaching regulatory limits, a moderate violation history, or both. Residents may want to review specific contaminant data and consider targeted filtration, especially for sensitive groups like children and pregnant women.
Health Information
Lead is a toxic metal that can leach from aging pipes and plumbing fixtures.
Even low levels of lead exposure can cause developmental delays in children, kidney damage, and cardiovascular effects in adults. The EPA action level is 15 ppb, but health experts recommend no safe level of lead in drinking water.
Lead enters water primarily through corrosion of lead service lines, lead solder, and brass fixtures — especially in homes built before 1986.
If lead is detected above 1 ppb, consider using a certified lead-removal filter (NSF/ANSI 53) for drinking and cooking water. Run cold water for 30 seconds before use if water has been sitting in pipes.
Copper can leach into water from copper plumbing, especially in newer homes or when water is acidic.
Short-term exposure above 1,300 ppb can cause gastrointestinal distress. Long-term exposure may cause liver or kidney damage. People with Wilson's disease are especially vulnerable.
Copper pipes, fittings, and faucets are the most common source. Corrosive (low-pH) water accelerates copper leaching.
If copper levels are elevated, flush pipes by running water for 15–30 seconds before use. Reverse osmosis and distillation systems effectively remove copper.
Common Questions
Tap water in Vancouver, Washington receives a grade of C (Fair) with a score of 56/100. While it generally meets minimum federal standards, there are some areas of concern including violation history or elevated contaminant levels. Sensitive populations (children, pregnant women, elderly) may want to consider additional filtration.
ZIP code 98668 is served by 5 water systems using surface water, groundwater sources, providing water to approximately 377,172 people. Multiple source types mean your water may come from a blend of surface and underground sources.
Lead was detected at 9.0 ppb in Vancouver, Washington. While this is below the EPA action level of 15 ppb, it exceeds the health guideline of 1 ppb recommended by health organizations. Consider a certified lead filter, especially if you have young children.
Yes — 7 PFAS compounds were detected in water serving Vancouver, Washington, and 2 exceed EPA maximum contaminant levels. PFAS are persistent chemicals linked to cancer, immune system effects, and developmental issues. A reverse osmosis or activated carbon filter certified for PFAS removal is recommended.
Water systems serving Vancouver, Washington have received 6 violations in the last 5 years, including 2 health-based violations. Violations can range from paperwork issues (monitoring & reporting) to serious health-based violations where contaminant levels exceeded safe limits. Review the violation details above for specifics.
Based on detected contaminants (lead, PFAS, copper), residents in Vancouver, Washington should consider: Reverse osmosis (RO) system — most effective for PFAS, lead, and other contaminants. Always look for filters with NSF/ANSI certification for the specific contaminants you want to remove.
