The Ej Water Cooperative serves a community with a median household income of $67,708 and an estimated 205,595 residents across its service area. Approximately 69% of housing stock was built before 1986, which increases the likelihood of lead service lines and older plumbing.

🌊 Where Does Your Water Come From?

Surface Water

Ej Water Cooperative's water is drawn from rivers, lakes, or reservoirs. Surface water sources are more exposed to agricultural runoff, stormwater, and upstream discharges, but they typically receive more intensive treatment before reaching your tap.

What This Means For You

Contaminant 1009 at 2 mg/L exceeds the EPA maximum of 0.004 mg/L. Intestinal damage, bone damage. Consider reverse osmosis filtration.

Haloacetic Acids (HAA5) at 5 mg/L exceeds the EPA maximum of 0.06 mg/L. Cancer risk; reproductive & developmental effects. Consider granular activated carbon (GAC) filtration.

Lead at 1 mg/L (action level) exceeds the EPA maximum of 0.015 mg/L (action level). Brain damage in children, kidney & blood pressure in adults. Consider reverse osmosis filtration.

Total Trihalomethanes (TTHM) at 5 mg/L exceeds the EPA maximum of 0.08 mg/L. Bladder & rectal cancer risk; reproductive concerns. Consider granular activated carbon (GAC) filtration.

Stage 1 DBP Rule at 7 mg/L exceeds the EPA maximum of mg/L.

PFAS Detected in Service Area

PFAS ("forever chemicals") have been detected in water serving this system's area. 72 detections recorded. 3 exceed federal EPA limits (4 ppt for PFOA/PFOS).

State limits: PFOA: 0.002 ppt, PFOS: 0.014 ppt

Health concern: PFAS are linked to cancer, thyroid disease, immune suppression, and developmental effects. They do not break down naturally.

Recommended filter: Reverse osmosis (RO) or activated carbon filters certified for PFAS removal. Find the right filter →
