Incidents
TTHM
Description
Trihalomethanes occur when naturally-occurring organic and inorganic materials in the water react with the disinfectants, chlorine and chloramine.
Health Effects
Liver, kidney or central nervous system problems; increased risk of cancer
Coliform (TCR)
Description
Coliforms are bacteria that are naturally present in the environment and used as an indicator that other, potentially harmful, bacteria may be present. Coliforms found in more samples than allowed is a warning of potential problems.
Health Effects
Not a health threat in itself; it is used to indicate whether other potentially harmful bacteria may be present5
Total Haloacetic Acids (HAA5)
Description
Haloacetic acids occur when naturally-occurring organic and inorganic materials in the water react with the disinfectants, chlorine and chloramine.
Health Effects
Increased risk of cancer
Atrazine
Description
Atrazine is a white, crystalline solid organic compound. Atrazine is a widely used herbicide for control of broadleaf and grassy weeds. Effective in 1993, its uses were greatly restricted.
Health Effects
Cardiovascular system or reproductive problems
