Methodology
Gas risk rankings use PHMSA gas distribution incident data (2004-2026), mapped to counties and ZIP codes. Risk scores (0-100) factor in total incidents, fatalities, and recency. Counties with more incidents, deaths, and recent events score highest. Data source: U.S. DOT Pipeline and Hazardous Materials Safety Administration.
Data sources: EPA Safe Drinking Water Information System (SDWIS), FEMA National Flood Insurance Program, EPA radon zone maps, EIA electricity rates, and Consumer Confidence Reports. Last updated: 2026-10-15.
Frequently Asked Questions
What is a gas distribution incident?
Gas distribution incidents involve failures in the local natural gas pipeline network — the pipes that carry gas from main lines to homes and businesses. These can cause explosions, fires, carbon monoxide poisoning, and property damage. PHMSA tracks all reported incidents nationally.
How can I protect my home from CO and gas leaks?
Install CO detectors on every level of your home (CPSC recommendation). Have gas appliances inspected annually by a licensed technician. Know the signs of a gas leak: rotten egg smell, hissing near gas lines, dead vegetation near pipelines. If you smell gas, leave immediately and call 911.
