Violation history
Ireland's water system has 3 total violations on record, including 0 health-based violations. 3 remain unresolved.
Flood & environmental risk
Dubois County has experienced 3 federally declared disasters since 1979. Flooding and severe storms can overwhelm water treatment plants, cause sewage overflows, and introduce agricultural runoff, bacteria, and sediment into drinking water supplies. Local water sources include Patoka River.
Where does Ireland's water come from?
Ireland's drinking water comes from surface water (rivers, lakes, or reservoirs), supplied by 1 water system serving approximately 4,395 people. Surface water sources are more susceptible to contamination from runoff, industrial discharge, and algal blooms, requiring extensive treatment. Nearby water bodies include Patoka River (river).
What Ireland residents can do
Recommended: Activated carbon or reverse osmosis filter. This addresses the specific contaminants found in Ireland's water.
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.
Ireland's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.
