Muskegon, MI
According to the U.S. Environmental Protection Agency's 2023 Toxics Release Inventory, Safe Drinking Water Information System, and Superfund National Priorities List, this Environmental Justice Screening Report covers Muskegon, MI (population 175,378).
According to EPA TRI, SDWIS, and Superfund NPL extracts, Muskegon, MI has an environmental burden score of 48/100 (grade C+), ranking #264 of 500 counties in this sample. Underlying disclosure counts: 37 TRI facilities releasing 10.9M lbs, 4 health-based SDWIS violation rows, and 9 Superfund sites. The score is a percentile of federal disclosure footprints, not a diagnosis of current community health harm.
Muskegon, MI sits near the middle of the national distribution at rank #264 of 500, with Superfund sites (97th percentile) the largest of four weighted indicator layers behind the county's composite score of 48/100 (grade C+). The four layers synthesized: Toxic Release Inventory (TRI) volume, Safe Drinking Water Act health violations, Superfund National Priorities List presence, and carcinogen-releasing facility density.
Of the 9 Superfund sites in this county (see the indicator breakdown above for the count), 7 are actively listed on the NPL.
Transparent derived index from EPA TRI / SDWIS / Superfund extracts: not an official EPA rating. Each of up to 500 counties is percentile-ranked on four rates (toxic lbs per capita 35%, health-based SDWIS rows per water system 25%, Superfund sites per 100k residents 20%, carcinogen-facility share 20%), then weighted. Population-less counties take a neutral 50th percentile on the per-capita indicators. See methodology.
A high burden grade does not by itself establish current health harm; it documents the cumulative regulatory and disclosure footprint drawn from EPA TRI, SDWIS, and Superfund data. Use the indicator breakdown below to see which component drives the score, and drill into the top chemicals and facilities for the underlying Form R filings. This percentile-based score is a different measure than the county profile's fixed-threshold risk score: expect the two numbers to differ.
