Abstract

• Utility Survey • Large portion of the contacted utilities participated on this survey • Utility survey provided valuable information on disinfection practices for both WSs and CSs • WS with source water of higher TOC or bromide (DBP precursors) practiced non-Cl2/Cl 2 system • Equal number of WS either practiced Cl 2/Cl2 and/or Cl2/NH2Cl, whereas larger portion of CSs practiced Cl2/NH2Cl • DBPs Precursors • For both WSs and CSs meeting the 80% MCLs (64 μg/L) of TTHMs will require finished water TOC ≤ 3.0 mg/L • For both WSs and CSs meeting the 80% MCLs (48 μg/L) of HAA5 will require finished water TOC ≤ 4.0 mg/L • At Distributions • For both WSs and CSs dominant DBP in distribution is TTHMs • The dominance of TTHMs is greater for Cl 2/NH2Cl system to Cl2/Cl2 system • TTHMs and HAA5 growth (i.e., of finished to distributed water) is similar for Cl2/Cl2 system but reduces for Cl2/NH 2Cl system • HAA5 slightly decreases in distribution system • No significant relationship were found on this survey for DBPs with water age.
