Contaminants
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
