Atascosa County, Texas: environmental and disease records

Cancer mortality in Atascosa County is 165.9 deaths per 100,000 people per year against a U.S. rate of 143.2, a statistically significant excess. The strongest disease signals are Kidney & renal pelvis deaths at 2.4 times the U.S. rate and Liver & bile duct deaths at 1.7 times the U.S. rate. Federal databases place 224 regulated facilities, sites and hazards inside the county, led by NPDES wastewater discharge permit (97), Rail grade crossing (52), Air permit holder (minor source) (15). EPA AirToxScreen estimates a lifetime cancer risk from outdoor air toxics of 30 in a million, driven mainly by formaldehyde.
