PID’s Assurance Monitoring Program Overview

  • The Assurance Monitoring Program is a new long-term water quality monitoring program that follows PID’s Recovery Sampling efforts. Its purpose is to verify that water distributed through the mains remains free of fire related Volatile Organic Compounds (VOCs).
  • The first phase of this program will be conducted over the course of 24 months.
  • Each of the approximate 1,300 sample sites will be tested during this period, covering the whole distribution system. The majority of these sample sites are considered Routine Sample Sites. Some areas have been identified as Focus Areas and will be sampled more frequently.
  • Focus Areas are sections of mains that had previously tested out of compliance during initial Recovery Sampling efforts. These sections of main have since tested in compliance and been cleared for potable service, but PID will continue to monitor them closely to ensure they remain in compliance.
  • In the first 6 months of the program, Focus Areas will be sampled once every 2 months, followed by a frequency of once per quarter for the following 6 months. Focus Areas will then be sampled semi-annually in the second year of the program.
  • The total number of samples collected per week for the program will gradually decrease until PID falls back into routine sampling.
  • If a sample tests out of compliance, site specific information can be accessed through the "More info" link in the Water Quality Assurance Monitoring GIS map when viewing the sample data.
