Drinking Water Treatment

The Safe Drinking Water Act (SDWA) of 1974 and the SDWA Amendments of 1986 and 1996 provide the regulatory framework that drive treatment technology implementation in the drinking water industry. The SDWA requires implementation of the best available technology for a given situation, which is determined by establishing a treatment approach that is both technologically and economically feasible. The SDWA provide the basis for removing and inactivating pathogens like viruses, Giardia, and Cryptosporidium through filtration and disinfection technologies yet recognizing that disinfection byproducts must be controlled with Stage 1 and Stage 2 Disinfection Byproducts rules. These regulations also establish maximum contaminant levels (MCLs) for various contaminants through the National Primary Drinking Water Regulations and National Secondary Drinking Water Regulations. The primary MCLs deal with pollutants that are a risk to human health; whereas secondary standards deal with constituents that are not a health risk but rather cause cosmetic or aesthetic issues like taste, odor, or color that are displeasing to consumers. The SDWA also provides MCLs for additional constituents through the Lead and Copper Rule and through establishment of MCLs for radionuclides and arsenic.

These regulations continue to evolve through the contaminant candidate list (CCL) and unregulated contaminant monitoring rule (UCMR) and Trussell Tech follows these trends with insight from leaders in the water treatment industry. The company’s founder, Dr. Rhodes Trussell, served on the Environmental Protection Agency (EPA) Science Advisory Board (SAB) that considers emerging concerns and establishes the pathway for new and emerging regulations. With this experience and background, Trussell Tech is comfortable navigating the complex myriad of regulations and providing a professional assessment on the direction that the regulations will be taking on certain constituents. Some of the biggest regulatory issues to impact water supplies in the future are perchlorate and hexavalent chromium.
