UCMR Page for CVA Communities for 2015
Massachusetts Water Resources Authority
Research for New Regulations
The US Environmental Protection Agency (EPA) periodically requires water systems across the country to conduct monitoring for substances that may be present in drinking water to help understand their national occurrence as part of the process of deciding whether to regulate these substances. Under the Safe Drinking Water Act Amendments, EPA is required once every five years to develop a list of up to 30 new contaminants that must be monitored by public water systems.
MWRA collected samples during 2013, 2014, and 2015 at locations throughout our service area for 21 substances and for 7 hormones.

UCMR Results for Chicopee Valley Aqueduct (CVA) Communities
MWRA collected samples from 2 CVA communities: Chicopee and South Hadley Fire District #1 in 2015. Wilbraham was not required to take UCMR chemical samples due to its small population, but was chosen to sample for hormones. Even with the extremely sensitive test methods used capable of detecting some substances at parts per trillion levels, we expected to find very few of the substances that we were required to test for due to MWRA’s highly protected watershed and reservoirs.

More information on these substances and UCMR3 can be found at at on the US EPA web site.
How will this data be used?
EPA will collect and analyze data for all three years and from systems all across the country to develop an understanding of the occurrence, level and distribution of these substances in drinking water. That data, along with information on potential health effects and water treatment effectiveness will be used by EPA to determine if any new regulations are needed.
