Marshall County, Kentucky: environmental and disease records

Cancer mortality in Marshall County is 183.6 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 1.6 times the U.S. rate. Federal databases place 339 regulated facilities, sites and hazards inside the county, led by Industrial wastewater discharge (127), NPDES wastewater discharge permit (80), Rail grade crossing (34). 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: 36.9064, -88.3331.
