THE UCMR UPDATE
Issue 10
Rolling Out the Red Carpet March 2007
Editor's Notes
The sequel to the Unregulated Contaminant Monitoring
Regulation outshines the previous release. This action
packed thriller is full of adventures and drama beyond
your wildest imagination. The casting in UCMR 2 is
magnificent. The States do a sensational job assisting
with implementation. Water systems show their diverse
talents playing many daredevilish roles. Not only do
they sample, but they also tackle the Safe Drinking
Water Accession and Review System (SDWARS) head
on. Laboratories demonstrate their extraordinary abili-
ties meeting the application and proficiency testing
(PT) criteria of the Laboratory Approval Program. The
suspense of monitoring is mind-boggling! Will the water
samples be below the minimum reporting limit (MRL)?
Can you handle the thrill?

Paparazzi Crowd for
Signing of UCIVIR 2
EPA's Administrator, Stephen L. Johnson signed the second cycle of the
Unregulated Contaminant Monitoring Regulation (UCMR 2) on December
20, 2006 and the rule was published on January 4, 2007. The UCMR 2
requires:
• All public water systems (PWSs) serving more than 10,000 people, and
a representative sample of 800 PWSs serving 10,000 or fewer people,
to conduct Assessment Monitoring (List 1) for 10 contaminants during
a 12-month period between January 2008 and December 2010.
• All PWSs serving more than 100,000 people, 320
selected PWSs serving 10,001 to 100,000 people,
and 480 selected PWSs serving 10,000 or fewer peo-
ple to conduct the Screening Survey (List 2) for 15
contaminants during a 12-month period between
January 2008 and December 2010.
• All laboratories gain EPA approval to analyze samples
for UCMR 2 through the Laboratory Approval Program. Eicitement in the airl
Box Office Blockbuster
The 1996 Safe Drinking Water Act (SDWA) amendments required EPA to
establish monitoring criteria for unregulated contaminants, and to identify
a maximum of 30 contaminants to monitor every five years. As a result, the
UCMR program was developed. The data collected through the program is
stored in the National Drinking Water Contaminant Occurrence Database
(NCOD) to facilitate EPA's review of contaminant occurrence, and to guide
the development of subsequent Candidate Contaminant Lists (CCLs).
The UCMR program benefits the environment and public health by provid-
ing EPA and other interested parties with scientific data on the occurrence
of these contaminants in drinking water, permitting assessment of the
population potentially being exposed and the levels of that exposure. This
is the primary source of exposure data the Agency uses to determine
whether to regulate these contaminants.

PWSs on the Walk of Fame
Want to know what it takes to be on the Walk of Fame? PWSs listen
closely....
• June 30, 2005 is the date EPA used when determining your total popu-
lation served, for purposes of rule applicability.
• Your total population served is the sum of the direct retail population
served plus the population served, if any, by any consecutive system(s)
receiving finished water from the wholesaler PWS. (Total Population
Served = Direct Retail Population + Consecutive System(s) Population)
• Finished water is water introduced into a distribution system and in-
tended for distribution and consumption without further treatment
(except necessary treatment to maintain water quality in the distribu-
tion system, such as booster disinfection, or addition of corrosion con-
trol chemicals).
• Monitoring must be completed within a 12-month period between
January 1, 2008 and December 31, 2010.

• PWSs are grouped into three population categories:
* More than 100,000. All PWSs serving more than 100,000 people
must participate in Assessment Monitoring (AM) and the Screen-
ing Survey (SS).
* Must arrange and coordinate sampling, arrange for sample
analysis, and review/approve data in SDWARS.
* 10,001-100,000. All PWSs serving more than 10,000 people
must participate in AM. Plus, 320 selected PWSs serving 10,001-
100,000 people must participate in the SS.
* Must arrange and coordinate sampling, arrange for sample
analysis, and review/approve data in SDWARS.
* 10,000 or fewer. 800 selected PWSs must participate in AM, and
480 selected PWSs must participate in the SS.
* Must sample using kits provided by EPA, and send samples
to the assigned EPA contract lab.
• All PWSs have an assigned monitoring schedule, though it can be
modified.
• Assessment Monitoring is required at each entry point to the distribu-
tion system (EPTDS). The Screening Survey is required at each EPTDS
and, for method 521, at the distribution system maximum residence
time (DSMRT) associated with that EPTDS.
• Surface water systems must sample quarterly, 3 months apart, within
a 12-month period, and ground water systems must sample twice, 5-7
months apart, within a 12-month period.
• All PWSs must use laboratories that are EPA approved to analyze sam-
plesforUCMR2.
The Award Goes to: States & Regions
EPA wants to thank all Regions and partnering States for their
assistance in implementing UCMR 2. Thus far, this includes
signing Partnership Agreements (PAs), reviewing the State
Monitoring Plans (SMPs), gathering large system inventory
(LSI), and notifying PWSs. We look forward to working with you
throughout the UCMR 2 cycle. (Now, please stand up and take
a bow.)

Large PWSs Buzzing about SDWARS2
I know that the anticipated release of the second version of the Safe Drink-
ing Water Accession and Review System (SDWARS2) has kept many of you
up at night. This state of the art, glamorous, much improved database out-
shines SDWARS1 beyond your wildest imagination.
SDWARS2 is your lifeline for the majority of your
UCMR 2 reporting requirements: http://cdx.epa.gov
All PWSs serving more than 10,000 people should
follow these red carpet steps:
PWSs sewing more than
10,000 people,
laboratories, States,
Regions and EPA
Headquaiteis use
SDWARS2.
1. Register. All PWS users that did not pre-register in the spring of 2006,
should have received a Customer Retrieval Key (CRK) letter in August
2006. Many of you have already registered for SDWARS2 through the
Central Data Exchange (CDX) during pre-registration or using your CRK
letter. The remaining PWSs should register now using your assigned
CRK letter! If you do not have your CRK letter, please call the UCMR
Message Center at 1-800-949-1581.
2. Contacts. Once you have registered, you must establish at least two
contacts within SDWARS2 before you can proceed. All PWSs must en-
ter an official and technical contact within SDWARS before April 4,
2007. Additional contacts are labeled as "Other." One of the best new
functions of the database allows you the choice of receiving automatic
e-mails when your lab posts data. Thus, you always know when to
check back to SDWARS2.
3. Nominate. If you have a CDX account for SDWARS, and want others at
your PWS to have access, please "nominate" them. You can nominate
new contacts using the Nominate User function within SDWARS2.
4. Inventory. Please verify that your inventory of sample locations listed in
SDWARS2 is correct. If you have any changes, please make them
within SDWARS before August 2, 2007. After August 2, 2007 you must
write EPA using either the mailing address, e-mail or fax listed in the
Fan Forum Section on page 9 of this Update, provide reasons for the
change, and wait for a response before you can change your inventory.
Page6
Issue 10
5. Schedule. EPA established sampling schedules for every PWS, and
posted them in SDWARS2. If you must change your schedule, you can
make changes within SDWARS2 before August 2, 2007. After August 2,
2007 you must write EPA using either the mailing address, e-mail or
fax listed in the Fan Forum Section on page 9 of this Update, provide
reasons for the change, and wait for a response before you can change
your schedule.
6. Laboratory. Laboratories approved to analyze
samples for UCMR 2 are posted on the Web
site: http://www.epa .gov/safewater/ucmr/
ucmr2/labs.html. Please refer to this list when
researching for a laboratory to analyze your
UCMR 2 samples. If you have any questions
about establishing a contract with the laborato-
ries, please refer to Chapter 5 in the UCMR 2
Reference Guide, http://www.epa.gov/
safewater/ucmr/ucmr2/utilities.html. After you
have established a contract with your labora-
tory, please instruct your lab to add your PWS
to their client list within SDWARS2. EPA plans
to give laboratories access to SDWARS in late summer or early fall of
2007.
Bright, Shiny, Better
7. Data. Your contracted laboratory must post your UCMR 2 data to
SDWARS2 within 120 days from the sample collection date. Unless you
un-checkthe "receive e-mail notification checkbox" during registration,
you will receive e-mails notifying you when your laboratory has posted
data to SDWARS2. Your PWS only has 60 days to review and act upon
the data in SDWARS2.
Important. The functions available in SDWARS change over time. Before
2008, you will not see the functions to review and approve data in
SDWARS2. However, after monitoring begins EPA will activate those func-
tions for you.
