Clark County, Washington: environmental and disease records

Cancer mortality in Clark County is 147.7 deaths per 100,000 people per year against a U.S. rate of 143.2, a statistically significant excess. The strongest disease signals are Brain & nervous system deaths at 1.3 times the U.S. rate. Federal databases place 1,353 regulated facilities, sites and hazards inside the county, led by NPDES wastewater discharge permit (695), Rail grade crossing (171), Gas station (mapped facility) (145). 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: 45.7997, -122.5181.
