Weck Laboratories has provided analytical support for the Environmental Protection
Agency's UCMR program for UCMR1 & UCMR2 and will do so again for UCMR3. The laboratory
has developed the methods for compliance with the Rule. All List 1 methods are currently
availabe for analysis in-house at Weck Laboratories! Utilities now have the opportunity
to do preliminary monitoring to determine vulnerability to UCMR3 contaminants.
As proposed, UCMR 3 would require public water systems (PWSs) to monitor for
28 chemicals and two viruses. All PWSs serving more than 10,000 people, and a representative
sample of 800 PWSs serving 10,000 or fewer people, would be required to conduct
Assessment Monitoring for 28 "List 1" chemicals during a continuous 12-month period
from January 2013 through December 2015. In addition, a targeted group of 800 PWSs
serving 1,000 or fewer people would be required to conduct Pre-Screen Testing for
two "List 3" viruses during a 12-month period from January 2013 through December
2015.
