Quarterly Trend
On January 4, 2007, EPA published the final Unregulated Contaminant Monitoring Regulation (UCMR 2).
Shortly after publication of the final rule, EPA sent out notices to large (those serving 100,000 persons or
more) public water systems (PWSs) that would be required to monitor under UCMR 2. A previous letter, sent
out on August 28, 2006, contained the customer retrieval key (CRK) for each PWS. Systems were urged to
use their CRK to register in the central data exchange (CDX) to input information into the Safe Drinking
Water Accession and Review System (SDWARS) for UCMR 2. During the second quarter of FY 2007, the
Hotline received 74 calls from PWSs concerning the CRK and the applicability of UCMR 2. Hotline staff
worked closely with EPA's Technical Support Center (TSC) in Cincinnati, OH to assist PWSs and
laboratories with implementation of the UCMR 2.

Frequently Asked Qs & As
This section provides answers to frequently asked
questions not necessarily represented in one of the Top
Ten Topic categories.
Q: EPA has developed an electronic data reporting
system for public water systems (PWSs) subject to the
Unregulated Contaminant Monitoring Regulation 2
(UCMR 2). This reporting system, the Safe Drinking
Water Accession and Review System (SDWARS), has
been pre-populated with large system sample location
inventory, such as PWS identification number, name,
facility identification, source water type, and sample
point identification, name, and type. Where did this
inventory information come from?
A: EPA pre-populated the large system sample location
inventory for UCMR 2 using recent large system
information provided by some states. In addition,
inventory information from the SDWARS, version 1.0
used during UCMR 1 and some information from the
Safe Drinking Water Information System (SDWIS) was
used. PWSs are responsible for verifying and correcting
this inventory information as well as adding any new
facility information or sampling points. Systems have
210 days from the publication of the January 4, 2007,
final UCMR 2 Rule (i.e., until August 2, 2007) to
complete this process. This information and other
essential elements of UCMR 2 can be found in the
Reference Guide for the Second Cycle of the
Unregulated Contaminant Monitoring Regulation
(EPA815-R-06-016, December 2006), available at
www.epa.gov/safewater/ucmr/ucmr2/pdfs/quide ucmr2
refe rre n ceq u id e. pdf.
Q: Is it possible to edit the Unregulated Contaminant
Monitoring Regulation 2 (UCMR 2) public water system
(PWS) inventory data that is pre-populated in the Safe
Drinking Water Accession and Review System
(SDWARS)?
A: Systems have until August 2, 2007 to revise sampling
location and monitoring schedules in SDWARS. After
August 2, 2007, a system must notify EPA directly if
there are sampling location or inventory changes, or if
the system cannot sample according to the established
schedule.
Q: The Unregulated Contaminant Monitoring Regulation
(UCMR) 1 Monitoring Program was comprised of three
separate lists of contaminants. Is there a Pre-Screen
Testing List (List 3) of contaminants under UCMR 2?
A: Pre-Screen Testing, the third tier of UCMR monitoring
that is designed for priority "List 3" contaminants, is not
required under UCMR 2. EPA retained the regulatory
language that supports Pre-Screen Testing authority as
part of the three-tiered UCMR framework. If EPA
decides to include Pre-Screen Testing, EPA will initiate a
rulemaking action to propose List 3 contaminants and
their associated analytical methods (72 FR 368, 371;
January 4, 2007).
Q: A consecutive system is a public water system
(PWS) that receives some or all of its finished water from
one or more wholesale systems (40 CFR 141.2). Are
consecutive systems subject to the Unregulated
Contaminant Monitoring Rule 2 (UCMR 2)?
A: Consecutive community water systems (CWSs) and
consecutive non-transient non-community water systems
(NTNCWSs) that purchase all of their finished water
from another system are not subject to UCMR 2. CWSs
and NTNCWSs that do not purchase their entire water
supply as finished water from another PWS must
monitor according to the applicable requirements (40
CFR 141.40(a)(2)).
Q: When is a public water system (PWS) required to
monitor for beta particles and photon emitters?
A: Beta particle and photon radioactivity monitoring will
be performed only by community water systems (CWSs)
designated by the state as "vulnerable" or
"contaminated." CWSs (both surface and ground water)
designated by the state as vulnerable must collect
quarterly samples for beta emitters and annual samples
for tritium and strontium-90 at each entry point to the
distribution system, beginning within one quarter after
being notified by the state. Systems already designated
by the state must continue to sample until the state
reviews and either reaffirms or removes the designation.
CWSs (both surface and ground water) designated by
the state as utilizing waters contaminated by effluents
from nuclear facilities must collect quarterly samples for
beta emitters and iodine-131 and annual samples for
tritium and strontium-90 at each entry point to the
distribution system, beginning within one quarter after
being notified by the state until the state reviews and
either reaffirms or removes the designation (40 CFR
141.26(b)).
Q: What are the requirements for becoming certified as
an operator of a public water system (PWS)? Does EPA
have some sort of test procedure?
A: EPA does not provide PWS operator certification.
Pursuant to the Safe Drinking Water Act Amendments of
Safe Drinking Water Hotline 2nd Quarter Report
3

-------
2nd Quarter FY 2007
1996, EPA developed and issued guidelines specifying
minimum standards for certification and recertification of
the operators of community and non-transient, non-
community PWSs. States are required to implement
these guidelines or an equivalent state program. In
addition, EPA will reimburse the training and certification
costs for operators of smaller systems (those serving
less than 3,300 persons) by providing grants to states.
Information about the operator certification program is
available at www.epa.qov/safewater/opcert/opcert.htm.

SAFE DRINKING WATER HOTLINE QUARTERLY REPORT
Second Quarter FY 2007
Appendix A: Federal Register Summaries
FINAL RULES
"Unregulated Contaminant Monitoring Regulation (UCMR) for Public Water Systems
Revisions; Final Rule"
January 4, 2007 (72 FR 367)
The Safe Drinking Water Act (SDWA), as amended in 1996, requires EPA to establish criteria
for a program to monitor unregulated contaminants and to publish a list of contaminants to be
monitored every five years. EPA published the first set of contaminants in 1999. This final
regulation meets the SDWA requirement by publishing the next set of unregulated contaminants
to be monitored and the requirements for such monitoring.
This final rule describes the design for the second Unregulated Contaminant Monitoring
Regulation (UCMR) cycle (i.e., UCMR 2) of 2007-2011. EPA is requiring monitoring of 25
chemicals using 5 different analytical methods. UCMR 2 monitoring will occur during 2008-
2010. Implementation of this final rule will benefit the environment by providing EPA and other
interested parties with scientifically valid data on the occurrence of these contaminants in
drinking water, thereby permitting the assessment of the population potentially being exposed
and the levels of that exposure. These data are the primary source of occurrence and exposure
data for EPA to determine whether to regulate these contaminants.
The effective date for this action is February 5, 2007.
"Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean
Water Act; National Primary Drinking Water Regulations; and National Secondary
Drinking Water Regulations; Analysis and Sampling Procedures; Final Rule"
March 12, 2007 (72 FR 11199)
This rule modifies the testing procedures approved for analysis and sampling under the Clean
Water Act and Safe Drinking Water Act. EPA proposed these changes for public comment on
August 18, 2003, and April 6, 2004. This rule also changes regulations under the Safe Drinking
Water Act that establish drinking water sampling and analysis procedures. The changes include
approval of vendor-developed methods, new EPA and Voluntary Consensus Standard Body
(VCSB) methods, updated VCSB methods, and approval of a modification to the test kit used
with Syngenta Method AG-625 that restricts its use in certain circumstances.
CORRECTIONS
"Unregulated Contaminant Monitoring Regulation (UCMR) for Public Water Systems
Revisions; Correction"
January 26, 2007 (72 FR 3916)
EPA published this correction to the UCMR 2 for Table 1 in 40 CFR 141.40(a)(3).

NOTICES
"Safe Drinking Water Act Determination; Underground Injection Control Program,
Determination of Indian Country Status for Purposes of Underground Injection Control
Program Permitting"
February 26, 2007 (72 FR 8380)
This notice announces the availability of EPA's Land Status Determination, which concludes that
the approximately 160 acres of land located in the southeast portion of Section 8, Township 16N,
Range 16W, in the State of New Mexico (the Section 8 land), is part of a dependent Indian
community under 18 U.S.C. 1151(b) and, thus, considered to be "Indian country." EPA is
therefore the appropriate agency to consider underground injection control permit applications
under the Safe Drinking Water Act for that land.
"Agency Information Collection Activities; Proposed Collection; Comment Request;
Underground Injection Control (UIC) Program; EPA ICR No. 0370.19; OMB Control No.
2040-0042"
February 28, 2007 (72 FR 8983)
The Underground Injection Control (UIC) Program under the Safe Drinking Water Act
established a federal and state regulatory system to protect underground sources of drinking
water from contamination by injected fluids. Owners or operators of underground injection
wells must obtain permits, conduct environmental monitoring, maintain records, and report
results to EPA or the state UIC primacy agency. States must report to EPA on permittee
compliance and related information. The mandatory information is reported using standardized
forms and annual reports, and the regulations are codified at 40 CFR Parts 144 through 148. The
data are used by UIC authorities to ensure the protection of underground sources of drinking
water.
"Notice of a Second Workshop on the Development of Regulations for Aircraft Public
Water Systems"
March 8, 2007 (72 FR 10528)
EPA held a second workshop on the development of regulations for aircraft public water
systems. This workshop will provide information about recent activities and an overview of
approaches for the proposed Aircraft Drinking Water Rule. This is the second workshop in a
series designed to gain perspectives from representatives from industry, government, public
interest groups, and the general public.
The workshop was held in Washington, D.C. on March 28-29, 2007.

"Total Coliform Rule / Distribution System Stakeholder Technical Workshop and Request
for Nominations"
December 28, 2006 (71 FR 78203)
EPA held a technical workshop in Washington, DC, to discuss available information on the Total
Coliform Rule (TCR) and available information regarding risks in distribution systems in support
of revisions to the TCR. If results from the workshop indicate that a formal consensus building
process is appropriate for the revision effort, the Agency will consider establishing a Committee
under the Federal Advisory Committee Act to provide advice and recommendations on how best
to utilize available information for potential revisions to the TCR and to address public health
risks from contamination of distribution systems. In addition, such a Committee could provide
recommendations to determine if further information is needed to be collected to address health
risks associated with distribution systems.
To prepare in advance for the potential establishment of a Federal Advisory Committee, EPA is
soliciting nominations for membership on the Committee in this notice.
The public meeting will be held on Tuesday, January 30, 2007, through Thursday, February 1,
2007. Submit nominations for a potential Federal Advisory Committee on or before January 29,
2007.
