Efforts to achieve Lead and Copper Rule (LCR) compliance, limit disinfection byproducts and coliforms, and satisfy consumer complaints may prompt operators to simulate changes in water chemistry before making treatment adjustments. Changing chemical dosage rates in a computer simulator prepares water operators to optimize corrosion control without risk to public health, damage to the water distribution system, or regulatory violations. Each step forward in the simulation registers a change in results, prompting a user to scan the indicated corrosion results and continue into the program or adjust chemicals and dosage rates for desired results. Progress is confirmed by reductions in lead, copper, and zinc levels and progress toward stabilized water quality. The article provides the steps to follow for the simulation procedure, and also a treatment checklist.
