Contaminants Found

Contaminant 2920
E. coli

Causes gastrointestinal illness; certain strains (e.g., O157:H7) can cause severe kidney failure and death.

Common source: Fecal contamination from humans or animals entering the water supply

EPA limit: Zero (no E. coli permitted in drinking water)

Gross Alpha

Alpha-emitting radioactive particles increase cancer risk, particularly from bone and other internal cancers.

Common source: Natural uranium and radium in geological formations

EPA limit: 15 pCi/L (excluding radon and uranium)

Nitrate

Causes methemoglobinemia (blue baby syndrome) in infants, reducing the blood's ability to carry oxygen.

Common source: Fertilizer runoff, septic systems, animal feedlots, natural deposits

EPA limit: 10 mg/L (as nitrogen)

Stage 2 DBP

Trihalomethanes and haloacetic acids that increase cancer risk and may cause adverse reproductive outcomes.

Common source: Chlorine disinfection reacting with natural organic matter in source water

EPA limit: TTHM: 0.080 mg/L; HAA5: 0.060 mg/L

TTHM

Total trihalomethanes are linked to increased risk of bladder cancer and adverse reproductive outcomes.

Common source: Reaction of chlorine disinfectants with naturally occurring organic matter in water

EPA limit: 0.080 mg/L (80 ppb)

Total Coliform (TCR)

Indicates possible presence of disease-causing organisms that can cause gastrointestinal illness.

Common source: Human and animal fecal waste, soil, vegetation

EPA limit: No more than 5% of monthly samples may be positive

Total Haloacetic Acids (HAA5)

Haloacetic acids are associated with increased cancer risk and potential reproductive and developmental effects.

EPA limit: 0.060 mg/L (60 ppb)
