Aldrin in Drinking Water
EPA limits, health effects, and what to do if your water is affected.
🩨 Health Effects
A banned organochlorine pesticide that is highly toxic to humans and wildlife. Accumulates in fatty tissue and the food chain. No current federal MCL exists in drinking water. Health effects include nervous system damage and possible cancer.
📍 Sources in Water
Used as an insecticide on corn and other crops and as a termiticide until it was banned in 1974. Persists in soil for decades. Residues can still be found in some groundwater near former treatment sites.
✅ What To Do
Activated carbon and reverse osmosis can remove aldrin. If aldrin is detected in your water, contact your utility or state environmental agency, as this may indicate historical pesticide contamination in your area.
Check your tap water for Aldrin
Search your ZIP code to see if your water system has had Aldrin violations, plus lead testing results and an overall safety grade.
Search your ZIP code →Data from the EPA's Safe Drinking Water Information System (SDWIS). MCLs reflect minimum federal standards; some contaminants may pose health risks below these thresholds.
