Federal databases place 11,134 regulated facilities, sites and hazards inside the county, led by Small hazardous waste generator (5,116), NPDES wastewater discharge permit (2,827), Large hazardous waste generator (876). 5 correctional facilities operate in the county. EPA AirToxScreen estimates a lifetime cancer risk from outdoor air toxics of 30 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: 33.6677, -117.7212.
