Kitsap, WA

Compiled by PlainEnviro Editorial, Environmental Data Editorial Team · July 13, 2026

Moderate Risk (41/100)

A PlainEnviro-computed score from reported facility/violation counts, not an official EPA rating, health forecast, or population-adjusted rate. See methodology. This is a different measure than the EJ Screening score for this county, which ranks it by percentile against every other tracked county rather than against fixed national thresholds.

Environmental data for Kitsap in Washington · Population: 276,581

Kitsap, WA is tracked across three EPA datasets covering 5 Toxics Release Inventory (TRI) facilities, 342 Safe Drinking Water Act systems, and 0 Superfund National Priorities List sites. Together these generate an environmental burden score of 41/100 (Moderate Risk), calibrated against national distributions for facility density, chemical release volume, Superfund concentration, and water-system health violations.

Industrial disclosures inside the county total 8.9M lbs of reported toxic releases under EPCRA Section 313, while 34 water systems carry an active health-based violation in the SDWIS record. EPA Air Quality System monitors logged a median AQI of 19 and a peak AQI of 69 in 2024, with 97% of observed days rated "Good" (0–50).

All figures below draw directly from federal EPA records, TRI self-reported emissions, SDWIS compliance history, NPL Hazard Ranking System scores, and AQS daily AQI summaries, and are not adjusted, weighted, or forecast. A past violation or elevated score does not itself indicate current unsafe conditions; it documents the regulatory and disclosure history publicly filed with the U.S. Environmental Protection Agency through the most recent reporting cycle.
