This slide presentation outlines information on controlling contamination in drinking water treatment chemicals. Topics outlined include: Status of Regulatory Adoption; Standard 60; overview of Standard 60 Technical Requirements; preventing Contamination during Production, Transport, and Storage of Treatment Chemicals; and, Storage Example: Sodium Hypochlorite (controlling perchlorate formation). Conclusions of the study included: ensure the chemical manufacturer as well as the distribution point are certified to NSF 60; limit contamination from transport by requiring dedicated containers or inspection of wash-out tickets; and, limit contamination during storage by following mfrs instructions and/or AWWA Specifications.
