UCMR3 2015 US EPA Required Unregulated Contaminant Monitoring Rule 3 Data Results

2015 UCMR3 Data Report

Click the link above for the MCSD results of the 2015 EPA required laboratory analysis of drinking water for currently unregulated potential contaminants.  Our results on water obtained from all three springs, Intake, Upper & Lower Elk demonstrate less than the minimum reporting level or none to extremely low levels of detection.

EPA uses the Unregulated Contaminant Monitoring (UCM) program to collect data for contaminants suspected to be present in drinking water, but that do not have health-based standards set under the Safe Drinking Water Act (SDWA). Every five years EPA reviews the list of contaminants, largely based on the Contaminant Candidate List. The SDWA Amendments of 1996 provide for:

  • Monitoring no more than 30 contaminants every five years
  • Monitoring only a representative sample of public water systems serving less than 10,000 people
  • Storing analytical results in a National Contaminant Occurrence Database (NCOD)
