The strongest disease signals are Bladder deaths at 1.6 times the U.S. rate and Lung & bronchus deaths at 1.2 times the U.S. rate. Federal databases place 635 regulated facilities, sites and hazards inside the county, led by NPDES wastewater discharge permit (285), Air permit holder (minor source) (117), Gas station (mapped facility) (49). One correctional facility operates in the county. EPA AirToxScreen estimates a lifetime cancer risk from outdoor air toxics of 20 in a million, driven mainly by formaldehyde.
