Travis County, Texas: environmental and disease records

Cancer mortality in Travis County is 112.1 deaths per 100,000 people per year against a U.S. rate of 143.2. Federal databases place 3,808 regulated facilities, sites and hazards inside the county, led by NPDES wastewater discharge permit (2,434), Gas station (mapped facility) (471), Auto repair or body shop (mapped facility) (178). One correctional facility operates in the county. EPA AirToxScreen estimates a lifetime cancer risk from outdoor air toxics of 30 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: 30.3344, -97.781.
