Washington County, Pennsylvania: environmental and disease records

Cancer mortality in Washington County is 160.5 deaths per 100,000 people per year against a U.S. rate of 143.2, a statistically significant excess. The strongest disease signals are Bladder deaths at 1.4 times the U.S. rate and Esophagus deaths at 1.3 times the U.S. rate. Federal databases place 1,530 regulated facilities, sites and hazards inside the county, led by NPDES wastewater discharge permit (682), Air permit holder (minor source) (227), Rail grade crossing (205). EPA AirToxScreen estimates a lifetime cancer risk from outdoor air toxics of 40 in a million, driven mainly by formaldehyde.

Rates are age-adjusted per 100,000 people. A cancer signal is marked significant when the lower bound of its 95 percent confidence interval is above the U.S. rate. Facility counts use active federal records located inside the county boundary. Approximate county center: 40.2151, -80.239.
