Unregulated Contaminant Monitoring Regulation
(UCMR)

• Congress told EPA to seek new health risks
• Look at occurrence and health risks
• EPA created UCMR program
• Looks at occurrence through sampling program
• Other programs look at health risk
• EPA created Contaminant Candidate List (CCL)
• List of contaminants that are
• Not regulated by national primary drinking water
  regulations
• Known or anticipated to occur at PWS, and
• May warrant regulation under SDWA
• Currently
• CCL2 contains 26 unregulated contaminants
• Sampling will occur July 2007 through June 2010

5
UCMR Regulatory status

• EPA will adopt rule in December (?)
• Current version is proposed
• Direct implementation by EPA
• TCEQ has agreement to assist with implementation
• But EPA will send letters to PWSs
• Questions can be directed to Mike Howell at TCEQ
  (512/239-1108)

11
Sample Sites

• Entry point sampling, except
• Nitrosamine samples are also collected at the
  Maximum Residence Time location in distribution
• TCEQ will get addresses from DBP sites if possible

- Proposed Rule Unregulated Contaminant
Monitoring Regulation (UCMR 2) monitoring is
proposed to occur during 2007-2010 and includes
26 unregulated contaminants and nine associated
analytical methods to be used in this monitoring
cycle. The UCMR program was developed in
coordination with the Contaminant Candidate List
(CCL). The CCL is a list of contaminants that are
not regulated by national primary drinking water
regulation, are known or anticipated to occur at
public water systems, and may warrant regulation
under the Safe Drinking Water Act. The data
collected through the UCMR program is being
stored in the National Contaminant Occurrence
Database (NCOD) to support analysis and review of
contaminant occurrence, to guide the CCL
selection process, and to support the
Administrator's determination of whether to
regulate a contaminant in the interest of
protecting public health. Background About this
regulation How did EPA select these
contaminants? What are the major differences
between UCMR 1 and 2? What are the environmental
and public health benefits? What is the EPA
Laboratory Approval Program for UCMR
2? Background The Safe Drinking Water Act (SDWA),
as amended in 1996, requires EPA to establish
criteria for a program to monitor unregulated
contaminants and to identify no more than 30
contaminants to be monitored every five years.
EPA identified and published unregulated
contaminants for the previous UCMR cycle (i.e.,
UCMR 1), and a revised approach for monitoring,
in the Federal Register dated September 17, 1999.
UCMR 1 established a tiered monitoring approach,
and required all large public water systems
(PWSs) and a representative sample of small
PWSs (serving 10,000 or fewer people) to monitor
for unregulated contaminants from 2001-2005.
(The original unregulated contaminant monitoring
program (1988-1997) utilized State primacy
and required PWSs serving greater than 500 people
to monitor.) Top of page Fact Sheet lt UCMR 2 lt

UCMR Frequency

• Samples based on OWNED Entry Points
• Not Purchased Entry Points
• GW
• 2 per year (biannual?)
