Notes:
1. Radium-226 and radium-228 are counted as two contaminants although their standard is combined.
2. Total THMs, haloacetic acids, and total coliforms are counted as one contaminant although both are combined standard: THMs (chloroform, bromodichloromethane, dibromochloromethane, bromoform); TC (total coliform bacteria including fecal coliforms and E.coli); HAA5 (monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, bromoacetic acid, and dibromoacetic acid).
3. Vinyl chloride is also known as chloroethylene & monochloroethylene.
4. These nine contaminants have a treatment technique instead of a MCL.
5. Aldicarb, aldicarb sulfone, and aldicarb sulfoxide are considered regulated contaminants although their MCLs are stayed.
6. Dichloromethane is also known as methylene chloride.
