UCMR Page for Wilbraham: 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 them. 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.

2015 UCMR Test Results for Wilbraham

Due to its small population size, Wilbraham was not required to sample for 21 chemicals that are part of the UCMR testing.  But, Wilbraham was one of the national locations chosen to test for hormones.  Only one of the hormones, 4-androstene-3,17-dione, was detected at an extremely low level, 0.0004 ppb, just above the detection limit of 0.0003 ppb.  All of the other 6 hormones were non-detect. 

Here is the complete list of hormones tested for in Wilbraham.

Hormones (7)
17-a-Ethynylestradiol 17-b-Estradiol
Estrone 4-androstene-3,17-dione
Estriol Equilin

More information on 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.
