McCurtain County, Oklahoma: environmental and disease records

Cancer mortality in McCurtain County is 222.8 deaths per 100,000 people per year against a U.S. rate of 143.2, a statistically significant excess. The strongest disease signals are Lung & bronchus deaths at 2 times the U.S. rate and Liver & bile duct deaths at 1.8 times the U.S. rate. Federal databases place 265 regulated facilities, sites and hazards inside the county, led by Rail grade crossing (139), Air permit holder (minor source) (31), NPDES wastewater discharge permit (26). EPA AirToxScreen estimates a lifetime cancer risk from outdoor air toxics of 30 in a million, driven mainly by formaldehyde.
