Chippewa County, Wisconsin: environmental and disease records

Cancer mortality in Chippewa County is 150.6 deaths per 100,000 people per year against a U.S. rate of 143.2. The strongest disease signals are Esophagus deaths at 1.6 times the U.S. rate. Federal databases place 376 regulated facilities, sites and hazards inside the county, led by Rail grade crossing (133), NPDES wastewater discharge permit (112), Gas station (mapped facility) (28). 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.

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: 45.0597, -91.2874.
