Ozaukee County, Wisconsin: environmental and disease records

Cancer mortality in Ozaukee County is 126.4 deaths per 100,000 people per year against a U.S. rate of 143.2. The strongest disease signals are Brain & nervous system deaths at 1.4 times the U.S. rate. Federal databases place 304 regulated facilities, sites and hazards inside the county, led by NPDES wastewater discharge permit (126), Rail grade crossing (89), Small hazardous waste generator (19). 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: 43.3676, -87.959.
