AWWA IMTECH57869

Compliance with the United States Safe Drinking Water Act requires that waterpurveyors take water quality samples at entry points to the distribution system as well asat various points within their water distribution system. These samples must be analyzedfor a variety of constituents and each constituent has its own required samplingfrequency. An individual constituent/location combination may be in one of severalmonitoring modes: initial, routine, increased, reduced or waiver. The monitoring modedepends, in part, on the historical concentrations recorded for the particular water qualityconstituent at a particular location. Development of a schedule for monitoring the waterquality of a water system is a complex task that most water systems conduct manually.Failure to monitor at the proper intervals may result in a violation of the Safe DrinkingWater Act and potentially the receipt of Notices of Violations and fines from theregulator.A computer program was developed for a City water purveyor in the state of Arizona tocapture the monitoring rules of the Federal Safe Drinking Water Act along with State andMaricopa County regulations. This program uses the rules to analyze historical waterquality data and develop the monitoring schedule. The program was also designed tointegrate with the City's existing water quality database. The Water CARS DrinkingWater Compliance database scheduler provides this Arizona utility with an insurancepolicy that does not replace human knowledge of regulations, but provides an additionaltool to assess past compliance (e.g., 3rd party audit capabilities) and helps ensure futurecompliance. Includes tables, figures.
