The Hominy serves a community with a median household income of $46,026 and an estimated 4,031 residents across its service area. Approximately 82% of housing stock was built before 1986, which increases the likelihood of lead service lines and older plumbing.

Environmental Justice Note: 100% of the population in this service area is classified as disadvantaged under EPA's EJScreen criteria. Communities with higher disadvantaged populations often face disproportionate environmental and health burdens, including aging water infrastructure and limited resources for remediation.

🌊 Where Does Your Water Come From?

Surface Water

Hominy'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.

How Hominy compares to EPA limits

Haloacetic Acids (HAA5) 20 mg/L (EXCEEDS LIMIT)
0 EPA Limit: 0.06 mg/L
Cancer risk; reproductive & developmental effects
Total Trihalomethanes (TTHM) 7 mg/L (EXCEEDS LIMIT)
0 EPA Limit: 0.08 mg/L
Bladder & rectal cancer risk; reproductive concerns

What This Means For You

Haloacetic Acids (HAA5) at 20 mg/L exceeds the EPA maximum of 0.06 mg/L. Cancer risk; reproductive & developmental effects. Consider granular activated carbon (GAC) filtration.

Total Trihalomethanes (TTHM) at 7 mg/L exceeds the EPA maximum of 0.08 mg/L. Bladder & rectal cancer risk; reproductive concerns. Consider granular activated carbon (GAC) filtration.

Fecal Coliform at 54 presence exceeds the EPA maximum of presence.

E. coli at 50 Zero tolerance (any positive sample triggers immediate action) exceeds the EPA maximum of Zero tolerance (any positive sample triggers immediate action). Severe GI illness; potentially fatal kidney failure in children. Consider UV disinfection (99.99%) filtration.

Lead and Copper Rule at 22 mg/L exceeds the EPA maximum of mg/L.

Haloacetic Acids (HAA5) was detected in this water system. granular activated carbon (GAC) filtration can reduce exposure.
