Office of Water (4101)
Attached is our final report on Pennsylvania's Reporting of Safe Drinking Water
Violations. We initiated our review as a result of information learned regarding the
Pennsylvania Department of Environmental Protection (PADEP) not reporting
violations of drinking water standards into the Federal data systems. The results
of our review indicated that PADEP may be excluding critical monitoring data from
its compliance determinations.
This final report contains issues that describe problems the Office of Inspector
General (OIG) has identified and corrective actions the OIG recommends. This
report represents the opinion of the OIG. Final determinations on matters in this
report will be made by EPA managers in accordance with established EPA audit
resolution procedures. Accordingly, the issues contained in this report do not
represent the final EPA position, and are not binding upon EPA in any enforcement
proceedings brought by EPA or the Department of Justice.

Pennsylvania May Not Be Reporting to EPA
All Maximum Contaminant Level Violations
The Pennsylvania Department of Environmental Protection (PADEP)
may not be reporting to the U.S. Environmental Protection Agency
(EPA) all maximum contaminant level (MCL) violations of the Safe
Drinking Water Act. Specifically, PADEP may be excluding critical
entry point monitoring data from its compliance determinations. This
exclusion of data, due to insufficient guidance and PADEP not always
ensuring its laboratory reporting procedures are followed, may have
contributed to EPA not being aware of a major health crisis at one
location. If PADEP does not correct these problems, the likelihood of
EPA not being made aware of future occurrences of public health risks
remains.
During our review, we also noted an additional reporting problem.
Specifically, PADEP does not notify EPA of all its drinking water
sources, because EPA does not explicitly require this information. In
the event of an environmental disaster, drought, or outside threat, it is
our opinion that EPA should have knowledge of all drinking water
sources that are in use or could be put into service quickly, in case this
information is needed to protect the public.
Instance of Contamination Sparked Concern
In early 2000, a public interest group notified EPA that drinking water
samples taken from an "emergency" source of water for the Borough of
Zelienople, PA, contained dangerously high levels of nitrates. The
Connoquenessing Creek, which was being used to supplement the
Borough's drinking water supply due to the shortage of available
water during drought conditions, was downstream from a steel
producer. In drinking water, nitrates can impair metabolism and
deprive the brain of oxygen. Nitrates above the safe drinking water
level pose an acute health risk for infants, pregnant women, and
nursing mothers.
The State had been aware of high nitrate levels in the
Connoquenessing Creek for several years. When the Creek was in use
during periods of 1998 and 1999, the public water system for
Zelienople notified the State of the high levels of nitrate. At the
suggestion of State officials, the public water system provided bottled
water to pregnant women and infants.
1
Report Number 2002-P-00007

-------
EPA responded to concerns raised by the public interest group by
issuing an emergency order to the steel producer causing the high
nitrate levels. This order required the steel producer to provide an
alternate source of water, such as bottled water, to the more than
4,000 customers of the public water system, and reduce dangerous
nitrate discharges from its operation.
Purpose of Report
We initiated our review based on the above information about
Zelienople. We obtained this information during a prior unrelated
audit and from EPA and Zelienople websites. From this information,
we learned that PADEP did not report nitrate violations to EPA. The
intent of this review was to identify similar occurrences in a sample of
public water systems. The objectives of the review were to determine
whether: (1) drinking water violations reported to PADEP are being
entered into its data management system, and (2) PADEP is reporting
the violations to EPA. Details on our scope and methodology are in
Exhibit 1.
Although we did not review the Zelienople public water system, we did
review 27 public water systems during our preliminary research. We
did not identify any instances of PADEP not entering violations into
its data management system or reporting them to EPA. Therefore, we
did not proceed with any further work in this area.
However, in an effort to understand how the exclusion of entry point
monitoring data into the Pennsylvania Drinking Water Information
System (PADWIS) could occur, we asked PADEP staff to explain its
procedures for entering data into PAD WIS when emergency, reserve,
interim, and seasonal water supply sources (referred to herein as non-
permanent entry points) distribute water to the public.
After discussions with PADEP and EPA Region 3 personnel, we noted
that PADEP's guidance does not specifically require compliance
monitoring for non-permanent entry points when water is distributed
to the public. In addition, PADEP does not always ensure that its
laboratory reporting procedures are followed. Further, we believe that
EPA national guidance is needed to establish definitions and
compliance monitoring requirements for non-permanent entry points.
If these issues are not addressed, the likelihood of EPA not being made
aware of future occurrences of public health risks remains. Thus, we
are reporting on this information.

Report Number 2002-P-00007

-------
Background
Both Federal and PADEP regulations require public water systems to
monitor for a wide variety of contaminants to verify that treated water
distributed to the public meets all drinking water standards. The
monitoring results are sent to PADEP for determination of compliance
with drinking water standards. When PADEP determines that an
MCL violation has occurred, PADEP is responsible for reporting the
information quarterly to EPA through the Federal Safe Drinking
Water Information System (SDWIS). The transfer of violation
information occurs from PAD WIS to SDWIS, allowing EPA to ensure
that unsafe conditions are promptly addressed and the public health is
protected. In essence, the "compliance process" includes both
monitoring and reporting requirements.
Monitoring for many chemical contaminants is required to be
conducted at entry points. An entry point is where treated water is
passed from the public water system to customers. In Pennsylvania,
consistent routine monitoring is required at permanent entry points.
For non-permanent entry points, monitoring is conducted at PADEP's
discretion. Details on the drinking water program are in Exhibit 2.
Regulations Require Monitoring and Reporting of MCL Violations
Title 40 Code of Federal Regulations Parts 141.23 and 141.24 requires
compliance monitoring to represent all sources. The monitoring
requirements for surface water systems for inorganic compounds,
volatile organic compounds, and synthetic organic compounds state:
Surface water systems shall take a minimum of one
sample at every entry point to the distribution system after
any application of treatment or in the distribution system
at a point which is representative of each source after
treatment.
Similar regulations apply to ground water systems. Also, for systems
that use more than one source of water, the requirements state:
If a system draws water from more than one source and
the sources are combined before distribution, the system
must sample at an entry point to the distribution system
during periods of normal operating conditions (i.e., when
water is representative of all sources being used.)
3
Report Number 2002-P-00007

-------
Pennsylvania Code also supports all sources being included in
compliance monitoring. Specifically, Pennsylvania Code Title 25
Section 109.303(4) requires that all samples for determining
compliance with MCLs for organic contaminants and inorganic
contaminants and with the special monitoring for unregulated
contaminants shall be taken at each entry point to the distribution
system after an application of treatment during periods of normal
operating conditions. If a system draws water from more than one
source and the sources are combined prior to distribution, the system
shall sample at the entry point where the water is representative of
combined sources being used during normal operating conditions.
Pennsylvania Code Title 25 Section 109.301(11) outlines monitoring
requirements for entry points that do not provide water continuously.
These entry points are required to have compliance monitoring for
inorganic compounds, volatile organic compounds, and synthetic
organic compounds during the period in which they provide water to
the public, unless special monitoring is required by PADEP under
Pennsylvania Code Title 25 Section 109.302.
The results of the monitoring are used by PADEP for determining
compliance with the MCLs. Not all MCL exceedances are violations of
the drinking water regulations. Compliance with the MCLs is based
on more than one sample collected at the entry point, and the
calculation for determining compliance can vary depending on the
contaminant. For example, for contaminants such as volatile organic
compounds, an individual sample may exceed the MCL value, but an
MCL violation will not occur unless the running annual average of all
samples collected over four quarters exceeds the MCL value. In
accordance with Title 40 Code of Federal Regulations Part 142.15,
each State that has primary enforcement responsibility shall submit
quarterly reports to EPA on new violations by the public water
systems in the State during the previous quarter.
PADEP Needs More Inclusive Definition of Compliance
After discussions with PADEP and EPA Region 3 personnel, we found
problems with PADEP's guidance and laboratory reporting procedures
that need to be addressed to prevent incidents where MCL violations
may not be reported to EPA.

Report Number 2002-P-00007

-------
Guidance Only Requires Compliance Monitoring for Permanent Entry Points
PADEP's guidance narrowly defines compliance and may contribute to
non-permanent entry point monitoring data from being excluded in
compliance determinations. PADEP's drinking water regulations, in
Section 109.301(11), require compliance monitoring at entry points that
do not provide water continuously. However, PADEP's Data
Management Staff Handbook, Appendix I, implies that compliance
monitoring is only required for entry points that are used on a regular
basis.
Specifically, PADEP's Data Management Staff Handbook states that
consistent routine monitoring is required at permanent entry points,
which are points used by the water system on a regular basis and are
generally relied upon for use all or nearly all the time. For
non-permanent entry points, the Handbook states:
Reserve entry points should be tested as deemed appropriate
at the discretion ofDEP staff when put into use.
Emergency sources, before put into use, should undergo
testing as deemed appropriate at the discretion ofDEP staff
This language, along with information from PADEP staff, indicates
that data from the monitoring conducted at non-permanent entry
points may not always be used for compliance purposes.
In addition, when a non-permanent and permanent source share the
same entry point, the entry point monitoring results subsequently
obtained when the non-permanent source was activated may or may
not be entered into PAD WIS to be used for automated compliance
determinations. This is because the compliance monitoring and
reporting requirements had already been fulfilled for that entry point.
If this situation should occur, it would conflict with the compliance
monitoring requirements in the federal regulations relating to
combined sources. These regulations require a system that draws from
more than one source and the sources are combined before distribution,
to sample when the water is representative of all sources being used.
Laboratory Reporting Procedures Not Followed
Federal and State regulations require compliance monitoring to be
conducted by a certified laboratory that uses an approved EPA
analytical testing methodology. PADEP's guidance requires certified
5
Report Number 2002-P-00007

-------
laboratories to report monitoring results to PADEP on specific forms
depending on the contaminant tested. These forms trigger routine
entry of the results into PAD WIS for automatic compliance
determinations. Based on discussions with PADEP officials, we
concluded that these forms are only used to report monitoring results
for permanent entry points - those regularly used to supply drinking
water to the public.
Non-permanent entry points provide drinking water to the public on a
temporary basis, such as during a drought, periods of increased
demand, or when permanent facilities are temporarily out of service for
maintenance or repairs. However, when these non-permanent sources
are used to supplement the permanent entry point, and water is
distributed to the public, the reporting procedures as outlined above
may not always be followed. For example:
•	Safe Drinking Water Act forms may not be routinely used by
certified laboratories when reporting sampling results for non-
permanent entry point monitoring. PADEP does not require
certified laboratories to report results for non-permanent entry point
monitoring on the Safe Drinking Water Act forms. The lack of using
the proper forms prevents the information from routinely being
entered into PAD WIS. Although the results can be manually
entered into PAD WIS, the possibility exists that the results will not
be entered and used for compliance.
•	If monitoring samples are not specifically classified as compliance
samples, the monitoring performed at PADEP's discretion may not
be conducted by a certified laboratory, or the laboratory may not use
the approved methodology. Either one of these circumstances will
prevent the data from being used for compliance purposes.
For all of the above reasons, critical monitoring data may be excluded
from being entered into PAD WIS for automated compliance
determinations, thus preventing MCL violations from being detected
and reported to EPA.
PADEP Needs Clear Availability Definitions
PADEP's guidance on the various availability definitions that are used
to classify whether a drinking water source is permanent, emergency,
reserve, interim, and seasonal needs to be more clearly worded.
Availability definitions are the foundation for tracking monitoring data
6
Report Number 2002-P-00007

-------
and the subsequent reporting of the data in PAD WIS. However, the
definitions are not clearly worded. For example, PADEP needs to
better define what constitutes an emergency situation and time frames
for its duration. The PADEP guidance indicated an emergency source
is only used during "temporary" emergency situations, such as a
drought. However, the drought conditions at Zelienople that
necessitated the use of the emergency source for several months during
1998 and 1999 were not temporary.
EPA Needs to Strengthen Guidance
EPA's SDWIS guidance may be encouraging States to formulate a
narrow definition of compliance. This guidance requires States to
report to EPA at least one source of water (the primary source) and all
surface water sources. According to clarification issued in June 1998:
Although only one source is needed to register a public
water system inventory in SDWIS, the intent of this
reporting requirement was always to have all sources of
water reported for each public water system. This
document therefore clarifies this requirement by
stating that all active sources of water should be
reported for each public water system.
However, this clarification does not define what is meant by "active."
Although this guidance clarifies an inventory reporting requirement,
this language may be encouraging States to associate permanent entry
points with compliance requirements. In Pennsylvania, the entry
points of active sources are those associated with permanent sources.
Compliance monitoring should be required for all "active" entry points
when put in use, and should represent combined sources.
Also, EPA needs to define its source availability codes. EPA does not
give States any information on how to define these codes (such as
permanent or emergency) in its guidance. As already noted regarding
Pennsylvania, its availability definitions need revision. In addition,
since each State can craft its own definitions, consistency problems can
occur when reporting to SDWIS. Because availability codes are the
initial step in organizing information in State tracking systems that
eventually report violations to EPA, we believe it is important for
source availability codes to be discussed in EPA guidance. Guidance to
States should make it clear that compliance monitoring and reporting
7
Report Number 2002-P-00007

-------
is required for all entry points when they are activated and distributing
water to the public.
EPA Needs Inventory of All Drinking Water Sources
During our review, we noted that PADEP does not notify EPA of all its
drinking water sources, because EPA does not explicitly require this
information for its SDWIS inventory. It is our opinion that EPA should
have knowledge of all drinking water sources that are in use, or could
be put into service quickly. EPA Headquarters and Region 3 staff
agreed. Drinking water supplies can be subject to natural or
environmental disasters, or outside threat. EPA should have
knowledge of all sources that could be affected, to ensure sufficient
preventive planning and that measures are in place to minimize
disastrous consequences.
Recommendations
We recommend that the EPA Region 3 Administrator:
1.	Require PADEP to align compliance monitoring guidance with
Federal and State drinking water regulations. Specifically,
PADEP's Data Management Staff Handbook, Appendix I, should
specify monitoring requirements for non-permanent entry points
that do not provide water continuously rather than conducting
monitoring at PADEP's discretion.
2.	Require PADEP to:
(a)	Follow its procedures contained in the Laboratory Reporting
Instructions. Specifically, PADEP should require certified
laboratories to submit monitoring results on the specific forms.
This will ensure that non-permanent entry point monitoring
data is entered into PAD WIS for compliance determinations,
and any MCL violations detected from this monitoring would
be reported to EPA.
(b)	Clarify its facility availability definitions contained in the
Data Management Staff Handbook. Specifically, PADEP
needs to re-evaluate what it considers appropriate use and
duration of an emergency entry point.
8
Report Number 2002-P-00007

-------
3.	Review compliance reporting procedures for other Region 3 States
to ensure they are interpreting compliance appropriately.
In addition, we recommend that the EPA Assistant Administrator for
Water:
4.	Revise SDWIS guidance to further clarify what is meant by
"active" as it applies to SDWIS reporting requirements, and
include a discussion of source availability codes.
5.	Require States to report to EPA all potential sources of drinking
water.
Agency and State Responses and OIG Evaluations
Region 3's Response to Draft Report
The Region emphasized that our review of the 27 public water systems
did not indicate any instances where PADEP did not report violations
to EPA. The Region noted that our statements about PADEP excluding
critical monitoring data are not substantiated by the results of the
research and the contents of the draft report. Zelienople was the only
case where PADEP failed to recognize and report a violation to EPA,
and the Region believes this was an isolated case. Further, the Region
believes that, given the information at hand, the risk of PADEP not
informing EPA of a serious health threat is not significant.
The Region also referred to "special purpose" samples, and that any
exceedances resulting from those samples are not compliance samples
and are not reportable to EPA. Region 3 would not expect the States to
report this information because the samples are taken for other than
compliance purposes. The Region suggested we correct the statements
regarding the reporting of additional monitoring results.
With regards to our recommendations, Region 3 agreed with
Recommendation 1. However, the Region did not know of any areas
where PADEP's compliance monitoring or reporting procedures and
guidance are not aligned with federal requirements. Region 3 did not
agree with Recommendation 2 and suggested the recommendation be
reworded. Region 3 agreed with Recommendation 3 and provided
information on actions underway.
9
Report Number 2002-P-00007

-------
OIG Evaluation of Region 3's Response
During our exit conference with Region 3, we clarified several issues.
We advised Region 3 that our review did not include the Zelienople
public water system, and that the information about that situation
included in our report was obtained during a prior unrelated audit and
from EPA and Zelienople websites. In addition, we explained that
during our limited review of 27 public water systems, some of our work
involved "special purpose" samples and that we understand that these
results are not used for compliance purposes. Further, we clarified that
our report focuses on the exclusion of non-permanent entry point
monitoring data from compliance determinations.
We clearly state in our report that our limited review of the 27 public
water systems did not disclose any reporting failures by PADEP.
However, based on our discussions with PADEP and Region 3
personnel, as well as the Zelienople situation - our reason for reviewing
PADEP's reporting of violations to EPA - we believe improvements to
PADEP's drinking water program are necessary. Only one instance,
like that at Zelienople, can have serious consequences.
With regard to Recommendation 1, we believe that PADEP's procedures
and guidance for compliance monitoring and reporting need to be
aligned with federal requirements. PADEP's Data Management Staff
Handbook notes that monitoring at non-permanent entry points is at
PADEP's discretion, rather than required, as outlined in its own
regulations as well as federal requirements. Although monitoring may
be performed at these entry points, the results may not always be
considered for compliance determinations. Federal and State
regulations clearly require compliance monitoring at non-permanent
entry points, and PADEP's guidance and procedures should ensure
this occurs.
We reworded Recommendation 2 as suggested. Regarding
Recommendation 3, Region 3 concurred and indicated actions are
already underway. The Region intends to formally document
procedures in all Region 3 States for sampling at sources other than
permanent sources. In addition, Region 3 indicated it will suggest that
the Office of Ground Water and Drinking Water add a section on
reviewing drinking water source use and monitoring for other than
permanent sources to its Data Verification Protocol. The Region's
proposed actions for Recommendation 3 meet the intent of our
recommendation.

Report Number 2002-P-00007

-------
PADEP's Response to Draft Report
PADEP emphasized that our review of the 27 public water systems did
not indicate any instances where PADEP did not report violations to
EPA. Also, they said our report does not cite any specific instances
where PADEP excluded critical monitoring data. Further, PADEP said
it is misleading for the OIG to conclude that public health is
jeopardized simply because some small amount of data may not be
transmitted to EPA.
PADEP said that the OIG incorrectly stated that compliance data is
specifically excluded from reporting to EPA based on the assumption
that sample data for sources is not being entered into PAD WIS and
reported to EPA. Chemical monitoring compliance for water supplies is
based on entry point samples (treated water), and not source water
samples (untreated water). PADEP's response indicates that when the
data from an entry point sample is entered into PAD WIS that results in
a violation of an MCL, the MCL violation is reported to EPA regardless
of the source of water. In addition, field staff can manually enter
violations into PAD WIS, which are also sent to EPA.
PADEP strongly disagreed with the statements indicating that
PAD WIS does not determine MCL compliance on results submitted for
emergency, reserve, interim, and seasonal entry points. PADEP said
these statements are incorrect because PAD WIS determines MCL
compliance on all entry point results regardless of the entry point
availability code in PADWIS. When results are submitted to PADEP
for a non-permanent entry point, PADWIS will automatically
determine MCL compliance for the entry point. When PADWIS
determines that an MCL violation has occurred and the field staff
validate it, the violation is transmitted to EPA.
Only monitoring compliance determinations for emergency, reserve,
interim, and seasonal entry points are not automated in PADWIS
because these non-permanent entry points generally are not used for
many years. This additional entry point monitoring (when another
source is brought online) should be tracked manually by PADEP staff,
and PADEP staff should require the certified laboratory to report the
data on Safe Drinking Water Act forms in order for PADWIS to
determine compliance with the Safe Drinking Water Act MCLs.
PADEP agrees that laboratory reporting guidance requires the
reporting of all analytical results conducted by the certified laboratory
to be submitted on Safe Drinking Water Act forms.
11
Report Number 2002-P-00007

-------
With regard to the recommendations, PADEP disagreed with
Recommendation 1, citing that the OIG audit failed to show any
discrepancies. PADEP also disagreed with Recommendation 2 because
EPA reporting guidelines do not require the reporting of MCL
exceedances, only MCL violations. PADEP agreed with
Recommendation 3, stating that the recommended action should be an
on-going requirement of EPA oversight of the State Safe Drinking
Water Programs. PADEP also provided comments on the
recommendations addressed to the Assistant Administrator for Water,
and conditionally agreed with those recommendations.
OIG's Evaluation ofPADEP's Response
During our exit conference with PADEP, we clarified several issues.
Specifically, we noted that our review did not include the Zelienople
public water system, and that the information about Zelienople in our
report was obtained during a prior unrelated audit and from EPA and
Zelienople websites. We clearly state that our limited review of the
27 public water systems did not disclose any reporting failures by
PADEP. This review was initiated as a result of the Zelienople
situation in which contaminated water was distributed to the public.
Based on our work, we believe improvements to PADEP's drinking
water program are necessary to ensure all non-permanent entry point
monitoring data is entered into PAD WIS and used for compliance
determinations, and any subsequent MCL violations reported to EPA.
Only then will EPA be able to adequately perform its oversight function
and ensure that no potential health problems exist.
Our report discusses PADEP's narrow concept of compliance, which we
believe creates the possibility that non-permanent entry point
monitoring results may be overlooked in compliance determinations.
Specifically, the guidance implies that consistent routine monitoring is
only required at regularly used (permanent) entry points. These
results are routinely used for compliance determinations. However,
PADEP's guidance suggests that non-permanent entry points are
subject to a different type of monitoring at PADEP's discretion, and the
results may not be used for compliance determinations. This guidance
not only directly impacts PADEP's processing of data but also does not
comply with State and Federal regulations requiring compliance
monitoring for contaminants at entry points that do not provide water
continuously.
We also discuss PADEP not always ensuring certified laboratories use
the Safe Drinking Water Act forms when reporting non-permanent
12
Report Number 2002-P-00007

-------
entry point monitoring results to PADEP. Following the structure set
forth in its Data Management Handbook, PADEP's current practice
requires certified laboratories to submit analytical results on the
specific forms only for routine monitoring on permanent entry points.
This is despite the fact that PADEP's laboratory guidance requires all
analytical reporting from the certified laboratories to be submitted on
Safe Drinking Water Act forms. Since the monitoring data for non-
permanent entry points (emergency and reserve) may not always be
used for compliance determinations, the laboratories report the
monitoring results on their letterhead rather than on the specific forms.
This is important because only results on Safe Drinking Water Act
forms are routinely entered into PAD WIS and used for automatic
compliance determinations.
Although results submitted to PADEP for non-permanent entry point
monitoring can be manually entered into PAD WIS, these results will be
discounted by PADEP if an uncertified laboratory performed the test or
the laboratory used an unapproved testing methodology. We realize
that quality assurance checks of results need to be performed.
However, our point is that these conditions will more likely occur if the
sample is not designated as a compliance sample.
We would like to note that PADEP agreed with our interpretation of
Federal and Pennsylvania regulations requiring that compliance
monitoring represents all sources. PADEP also agreed that its
laboratory reporting guidance requires the reporting of all analytical
results conducted by a certified drinking water laboratory to be
submitted on the Safe Drinking Water Act forms. Further, PADEP
stated that staff should require the certified laboratory to report the
analytical data on the forms in order for PAD WIS to determine
compliance with the MCLs.
Assistant Administrator for Water Response to Draft Report
The Assistant Administrator agreed with recommendations 4 and 5 and
provided proposed actions and completion dates. The response
indicated the Office of Ground Water and Drinking Water (OGWDW)
will evaluate the need for additional guidance to clarify what "active"
means regarding sources of drinking water. If a determination is made
that the problem is widespread, guidance will be provided to ensure
that appropriate actions are taken to protect public health. If the
problem exists only in a few States, individual technical assistance and
guidance will be provided by the appropriate regional office.
13
Report Number 2002-P-00007

-------
In addition, it was indicated OGWDW will evaluate the need for
requiring States to report all sources of drinking water. However,
information to be routinely reported to EPA, other than that specifically
identified in the regulations, needs to be evaluated and recommended
by the State/EPA Data Sharing Committee. If it is found that
intermittent and emergency sources of drinking water should be
maintained by EPA, the OGWDW will work with the Committee to
determine the best method for implementation.
OIG's Evaluation of Assistant Administrator's Response
Although the proposed actions provided by the Office of Water meet the
intent of our recommendations, a portion of Recommendation 4, relative
to SDWIS source availability codes, was not addressed in the response.
The response to that portion of the recommendation was discussed
during our exit conference. OGWDW expressed an interest in adding
clarifications on availability codes to the SDWIS dictionary. With
regard to OGWDW providing additional guidance on the word "active,"
feedback obtained during a conference call with the regional offices
indicated States were interpreting the guidance appropriately and
there was no need for additional guidance. However, OGWDW advised
there is a need to clarify how an emergency source should be used. It is
expected that the proposed actions will be completed by April 2002.

Scope and Methodology
We began our research on November 16, 2000. We attended a training course on
PADWIS provided by PADEP personnel. We reviewed files for 27 public water
systems in Pennsylvania. We visited three PADEP Regional Offices to review
various files and discuss issues with personnel. We completed our field work on
August 28, 2001.
Based on our research, we determined that we should not proceed with an audit.
However, during our research, we noted various areas of concern that if not
corrected by PADEP, the likelihood of EPA not being made aware of future
occurrences of public health risks remains. Therefore, we discussed those issues
with EPA Headquarters and Region 3 personnel, as well as PADEP personnel. We
reviewed the various regulations and guidance related to the issues noted. Although
Pennsylvania lists four different potential sources of water in addition to
permanent - emergency, reserve, interim, and seasonal - we focused on the first,
two, which appeared to be more likely to be used.
We issued our draft report on November 26, 2001. We received a response from
PADEP on December 20, 2001. Region 3 provided a response on January 8, 2002,
and the Assistant Administrator for Water provided a response on January 31, 2002.
Based on these comments, we revised our report; however, our positions remain the
same. These responses are summarized after the "Recommendations" section of this
report, and are included in their entirety in Appendices A through C. We held exit
conferences with the EPA Office of Water, Region 3, and PADEP during
February 2002.
We performed our work in accordance with the Government Auditing Standards,
issued by the Comptroller General of the United States.

Exhibit 2
Details on Drinking Water Program Requirements
The Safe Drinking Water Act was passed by Congress in 1974 to protect public
health by regulating the nation's public drinking water supply. The law was
amended in 1986 and 1996 and requires many actions to protect drinking water and
its sources - rivers, lakes, reservoirs, springs, and ground water wells. The Act
required EPA to set national health-based standards to protect against both
naturally occurring and man-made contaminants that may be found in drinking
water. These standards are called maximum contaminant levels (MCLs). The MCL
is the highest level of a contaminant that is allowed in drinking water delivered to
the public. These levels are enforceable standards.
The Act gave EPA authority to delegate to States primary responsibility (primacy)
for enforcing the regulations. States with this authority must adopt standards at
least as stringent as EPA's, and must make sure water systems meet these
standards. In addition, States should ensure water systems monitor for
contaminants, review plans for water system improvements, conduct on-site
inspections and sanitary surveys, provide training and technical assistance, and
take action against water systems not meeting standards. Pennsylvania has been
delegated primacy.
Both Federal and PADEP regulations require water systems to monitor for a wide
variety of contaminants to verify that the water they provide to the public meets all
Federal and State standards. The monitoring results are sent to PADEP for
determination of compliance with drinking water standards. When PADEP
determines that a MCL violation has occurred, PADEP is responsible for reporting
the information quarterly to EPA through SDWIS. The transfer of violation
information occurs from PAD WIS to SDWIS, allowing EPA to ensure that unsafe
conditions are promptly addressed and the public health is protected. In essence,
the "compliance process" includes both monitoring and reporting requirements.
The major classes of contaminants water systems must monitor include volatile
organic compounds, synthetic organic compounds, inorganic compounds,
radionuclides, and microbial organisms. Monitoring for these contaminants takes
place on varying schedules and at different locations throughout the water system.
Regulations require public water systems to determine compliance with the MCLs
for volatile organic compounds, synthetic organic compounds, and inorganic
compounds by taking samples at entry points to the distribution system at a location
where water is representative of all sources. Entry points can be designated to
include one or more sources of water supply. If a source of water that supplements
17
Report Number 2002-P-00007

-------
the permanent supply has its own entry point, the regulations require monitoring at
this entry point when the source is in use. For example, if the source is not used for
2 years, this water does not need to be sampled during that 2-year period. However,
once that source is put into use, compliance monitoring and reporting is required for
its entry point. If drinking water entry points contain "combined" sources (more
than one source) of water, the compliance sample and monitoring is required by the
regulations to represent normal operating conditions, and be representative of all
sources.
In addition, Federal and State regulations require compliance monitoring to be
performed by a certified laboratory. The laboratory must use an EPA-approved
method to analyze the results. Under PADEP's guidance for laboratory reporting,
laboratories are required to report the results of all monitoring on Safe Drinking
Water Act forms to ensure routine input of the results into its data management
system for automatic compliance determinations. Pennsylvania uses PADWIS, a
comprehensive data management system, to support and manage the safe drinking
water program.
PADWIS contains several different subsystems that store specific types of drinking
water information. The Inventory Subsystem contains information pertaining to
sources of water supply for each public water system. It also includes the source
availability, location, service area, treatment plant information, entry point
information, and monitoring frequency for the contaminants. The Sample
Subsystem contains the sampling results from compliance monitoring for each
public water system. The certified laboratory may send the results of monitoring
electronically, or PADEP may manually enter this information. PADWIS
automatically generates potential violations based on the data in the Sample
Subsystem. Although violations are automatically generated, field staff may also
manually add violations to PADWIS. Potential violations must be validated prior to
being captured in the Violation and Enforcement Subsystem. Valid violations are
reported to EPA on a quarterly basis.
SDWIS stores basic information (name, identification number, and source of water)
as well as violation and enforcement information for each water system. EPA uses
this information to determine if and when it needs to take action against non-
compliant systems, oversee State drinking water programs, track contaminant
levels, respond to public inquiries, and prepare national reports to Congress and the
public on the status of public drinking water. EPA also uses the information in
SDWIS to evaluate the effectiveness of its programs and regulations, and to
determine whether new regulations are needed to further protect the public health.

Review of Draft Report No. 2001-000398: Pennsylvania's
Reporting of Safe Drinking Water Violations
Thomas C. Voltaggio
Acting Regional Administrator (3DA00)
Carl A. Jannetti
Divisional Inspector General For Audit
Mid-Atlantic Division (3AI00)
Thank you for the opportunity to respond to the above referenced draft report and to
comment on the recommendations of the report. We appreciate the opportunity to provide input
and to offer clarification of the Public Water System Supervision (PWSS) Program and the
National Primary Drinking Water Regulations. We also appreciate the Office of Inspector
General for Audit's detailed reviews conducted of monitoring and reporting data for 27 water
suppliers in Pennsylvania. These comprehensive reviews of water systems with raw water intakes
on streams with impaired water quality provided valuable assurance regarding the safety of public
water supplies coming from those sources of drinking water.
The Region's response includes general and specific comments related to the factual
accuracy of the report, actions taken and comments on the recommendations. This response
covers the survey report and the recommendations for the Administrator of the U.S.
Environmental Protection Agency (EPA) Region III. The Office of Water will be responding
separately to the recommendations made to the Assistant Administrator for Water.
General Comments
In both of your November 26, 2001 transmittal memoranda, you state that during this
preliminary research, your Office found that the Pennsylvania Department of
Environmental Protection (PADEP) is not reporting to EPA all instances of drinking
water standards being exceeded because the Department is excluding critical information
from its compliance determinations. EPA Region III recommends that the final report
clarify that the only identified instance of PADEP not reporting a violation was in relation
to the Zelienople water system case where PADEP did fail to recognize and report a
violation to EPA. The Zelienople case seems to be an isolated incident. The review of 27
selected water systems during the preliminary research did not find any instances where
PADEP failed to report violations. Except for the Zelienople water system case, EPA
Region III has no evidence to say that PADEP does not meet the PWSS program primacy
Report Number 2002-P-00007

-------
requirements found in 40 C.F.R. § 142. The final report and associated correspondence
should more clearly reflect this.
Monitoring requirements for inorganic, organic and synthetic organic chemicals, as
specified in 40 C.F.R. §§ 141.23 and 141.24, specify that water suppliers must take
samples at every entry point to the distribution system which is representative of each
source, after treatment. The requirements also state that each sample [for compliance
purposes] must be taken at the same sampling point unless conditions make another
sampling point more representative of each source's treatment plant. The final report
should acknowledge that samples taken elsewhere for special purposes are not considered
compliance samples and, as such, any exceedances resulting from those samples are not
required to be reported to EPA. Another example where a single sample result that
exceeds the drinking water standard is not a violation is when the result is to be averaged
with other samples taken either as a confirmation sample, or when compliance is
determined by calculating running annual averages of quarterly samples. If the average is
below the MCL, there is no violation.
Not all MCL exceedances are violations of the National Primary Drinking Water
Regulations (NPDWR). State primacy agencies such as PADEP are only required to
report violations of the NPDWRs to EPA. It is the primacy state's discretion to report
sample results that exceed the MCL if they are samples taken for purposes other than for
compliance monitoring, e.g., for investigation or assessment purposes of source water
prior to treatment, or in the distribution system. The report refers to "additional
monitoring" in several places and infers that PADEP has committed an error for not
reporting results from this additional monitoring. Many times, monitoring results from
these special purpose sampling events cannot be used for compliance determination
purposes based on where the sample was taken, how the chain of custody was treated and
the laboratory methods used to perform the analyses.
EPA Region III would not expect state primacy agencies to report most of this
information. States may use discretion in reporting special purpose sampling results and
must report violations generated by these results if the state determines that those results
are to be used for compliance determination purposes. The final report should correct
statements made regarding MCL exceedances and additional monitoring results reporting
(such as in the November 26, 2001 memorandum, the title on page 1, the second sentence
of the first paragraph of page 2 and on page 4, last sentence, second paragraph).
Specific Comments
Page 1
The title "Pennsylvania Is Not Reporting to EPA All Instances of Safe Drinking Water
Levels Being Exceeded" is not factual and should be worded in the past tense. There is no
evidence, other than the historical knowledge of what happened in the Zelienople case,
that PADEP continues to violate federal requirements.
21
Report Number 2002-P-00007

-------
The draft report states that PADEP is not reporting all exceedances of drinking water
standards. Since the preliminary research did not find any reporting failures on the part of
PADEP, the report should be modified to reflect that, with the exception of the Zelienople
case, PADEP is reporting MCL violations to EPA as required. EPA Region III also
believes that, given the information at hand, the risk of PADEP not informing EPA of
serious health threats is not significant. The report should accurately reflect this situation.
It is stated in the last paragraph that during subsequent research, the Office of Inspector
General noted that PADEP is excluding critical data from its compliance determinations
for systems using emergency, reserve, interim and seasonal water sources. This statement
does not appear to be substantiated by the results of the research and the contents of the
draft report. The only instance like this mentioned in the draft report was the Zelienople
water system, which was not a public water supply reviewed during this preliminary
research. We recommend that the final report reflect this.
The references to bioterrorism here and on page 6 are misleading and not appropriate
since there have been no instances of bioterrorism in public water supplies. The
statements may cause the public to assume otherwise and should be removed.
Page 2
Monitoring for many chemical contaminants is done at entry points to the distribution
system. It is not accurate to say that all chemical contaminants are sampled at entry
points to the distribution system (second paragraph, first sentence ).
While it is true that federal and state regulations require monitoring that reflects all entry
points to the distribution system, it is not true that monitoring must be conducted at all
permanent sources. A permanent source may only be used very infrequently, if ever.
These sources and their respective entry points to the distribution system do not need to
be monitored unless they are active sources providing water to the public. Federal and
state regulations offer the authority to require additional monitoring on a case by case
basis since the numerous situations are difficult to capture in a one size fits all regulation.
Page 3
EPA does not have any strong evidence that nitrates above the MCL are unhealthy for all
people. There is limited evidence that nitrates significantly above the MCL of 10 mg/1
(i.e.>45 mg/1) may be unhealthy for adults. The third sentence in the third paragraph
would be accurate if it was modified to read as follows: "Nitrates above the safe drinking
water level can pose an acute health risk for bottle-fed infants six months of age or less."
Page 6
For purposes of EPA Region III oversight of the PWSS Program, the Region does not
need an inventory of all drinking water sources. Many sources remain on state inventories
even though they have been taken out of service and abandoned (e.g., well pumps pulled
and wells properly plugged and unprotected springs taken out of service) due to reasons
such as water system consolidation or replacement of unsafe sources. EPA Region III
agrees that we need inventory information on drinking water sources that are in use, or
22
Report Number 2002-P-00007

-------
could be put into service quickly, but not on all possible sources. The methodology of the
preliminary research as stated in Exhibit 1 used this same logic when the researchers
focused only on emergency and reserve sources but not on all possible sources.
Page 11
Exhibit 2 reviews details on the Safe Drinking Water Act, specific drinking water
regulations and the PWSS program in general. It does not discuss much in the way of
guidance. This exhibit would be more appropriately named "Details on the PWSS
Program" or "Details on Drinking Water Program Requirements."
Recommendation Concurrence/Nonconcurrence
Recommendation 1
EPA Region III agrees with this recommendation. We do not, however, know of any areas where
PADEP's compliance monitoring or reporting procedures and guidance are not aligned with
federal requirements. The Zelienople case aside, the preliminary research in this draft report and
programmatic file reviews in the past indicate PADEP is following PWSS Program requirements.
Recommendation 2
EPA Region III does not concur with this recommendation. EPA Region III has clarified with
PADEP that the Department must report all MCL violations for sources of drinking water that are
supplying water to the public. MCL exceedances at sources of water not providing water to the
public are not required to be reported to EPA. EPA Region III suggests that Recommendation 2
be worded as follows: "Require PADEP to clarify data management procedures to ensure the
reporting of maximum contaminant level violations for all water sources in use."
Recommendation 3
EPA Region III concurs with this recommendation. Actions in this regard are already underway
and are noted below.
EPA Region III Actions Items
EPA Region III met with state PWSS Program directors on December 11-12, 2001 and
informed them of this potential problem area. The state directors were asked to comment
on how their programs handle sampling at sources other than permanent sources. Two of
the Region III states present could confirm at the meeting that, regardless of a source
being classified as seasonal, emergency, interim or other, they require that a full range of
testing be done before allowing the source to be placed back into service. The Region will
formally document procedures in all Region III states in a written request and during
regular state program evaluations and file audits.
23
Report Number 2002-P-00007

-------
EPA Region III has reviewed reports from data verification audits conducted by the
program office from 1992 through 2001 to determine whether similar discrepancies were
found in Pennsylvania or other states. No similar occurrence was found. It is important
to note, however, that the PWSS Program Data Verification Protocol does not have a
specific section on reviewing source usage of other than permanent sources. EPA Region
III will recommend that the Office of Ground Water and Drinking Water add a section on
reviewing drinking water source use and monitoring to determine if a source labeled in the
federal data system as "emergency ," "interim," "seasonal" or "other" is actually used as
anything other than as labeled and sampled accordingly.
Thank you for this opportunity to comment on the draft report. If there are any questions
on this response, please contact me or have your staff contact Rick Rogers, Chief of the Drinking
Water Branch, at 215-814-5711.

Dear Mr. Jannetti:
Enclosed is our response to your draft report on Pennsylvania's Reporting of Safe
Drinking Water Violations.
The Safe Drinking Water (SDW) Program at the state and federal levels is extremely
complex. We would like to recognize the efforts of Teri Woodcock, Anne Bavuso and Niam
Chernosky of your staff, who conducted this review, to learn as much as possible about how the
SDW Program is implemented in Pennsylvania and at EPA Region III. Your review of 27 public
water systems during the preliminary phase of your audit did not disclose any instances of the
Pennsylvania Department of Environmental Protection (PADEP) not entering violations into its
data management system or reporting them to EPA, which supports our position as outlined in
our response.
We believe that your staffs subsequent research, which noted that PADEP excluded
critical data from compliance determinations for systems that used other than permanent supply
sources, reached several erroneous conclusions based in part on an incomplete understanding of
the SDW Program's complex regulatory and data management requirements. However, your
recognition that some of the issues stem from federal guidance deficiencies, which will require
EPA to work with Pennsylvania and the rest of the states to correct those deficiencies, is
appreciated.
Pennsylvania and other states with primacy for the federal SDW Program are the frontline
in the effort to ensure that the health of our citizens and visitors consuming water from public
water systems is protected. As you will note in our response, that program includes a great deal
of pro-active effort that is in addition to what the federal SDW Program requires to reduce or
prevent public health risk. Self-monitoring by public water systems when taken in context with
that overall effort is an important part of the total picture of the risk to public health. However,
taken by itself, it cannot be used to determine the extent of the total public health risk.

PADEP Response to OIG Draft Report on
Pennsylvania's Reporting of Safe Drinking Water Violations
Report No. 2001-000398 November 26, 2001
We would like to emphasize that the OIG preliminary review of 27 randomly selected public
water systems across Pennsylvania did not disclose any instances of PADEP not entering
violations into the data management system (PADWIS) or reporting these violations to EPA.
This OIG Draft Report on Pennsylvania's Reporting of Safe Drinking Water Violations
(hereinafter "Report") does not cite any specific instances of water systems reviewed where
PADEP excluded critical data from any compliance determinations for systems using emergency,
reserve, interim or seasonal water supply sources.
The report incorrectly states that compliance data is specifically excluded from reporting to EPA
based on the assumption that sample data for sources is not being entered into PADWIS and
reported to EPA. Chemical monitoring compliance for water supplies is based on entry point
samples, which are treated water, and not source water samples, which are raw untreated water.
When the analytical result from an entry point sample is entered into PADWIS that results in a
violation of a maximum contaminant level (MCL), the MCL violation is reported to EPA,
regardless of the source of water. In addition, field staff can manually enter violations
(monitoring or MCL) into PADWIS, which are also sent to EPA.
According to the Federal Safe Drinking Water regulations at 40 CFR Part 141, Subparts B and G,
which are incorporated by reference in the Pennsylvania Safe Drinking Water regulations,
chemical MCL violations are based on analytical results from water system entry points. Source
water analytical results may exceed an MCL value, but they will not result in an MCL violation if
the water is not served to the public or if the water is treated to below the MCL before delivery to
the public.
In addition, compliance with the Safe Drinking Water regulations is based on more than one
sample collected at an entry point. For example, a nitrate entry point sample result may exceed
the MCL value of 10 mg/L, but it will not be an MCL violation if the average of the original
sample and a check sample collected within 24 hours of the original are below 10 mg/L. For
contaminants such as VOCs (volatile organic chemicals), an individual sample may exceed the
MCL value, but an MCL violation will not occur unless the running annual average of all samples
collected over 4 quarters exceeds the MCL value.
The EPA data reporting requirements are referenced in the Consolidated Summary of State
Reporting Requirements for the Safe Drinking Water Information System (SDWIS). Under the
reporting requirements for Phase I, II, IIB, and V Rules, which includes the inorganic chemicals
(IOCs), volatile organic chemicals (VOCs) and synthetic contaminants (SOCs), the only SDWIS
reporting requirements for the States are violations (monitoring and MCL), violations returned to
compliance, public notification violations, and formal enforcement actions. Nowhere is it
indicated that exceedance of an MCL value is a SDWIS reporting requirement for the States.
Monitoring of the source water (untreated water) for compliance with the safe drinking water
regulations is not required at the federal level, only entry point monitoring representative of all
28
Report Number 2002-P-00007

-------
sources being used. Pennsylvania requires water quality monitoring of source water (Title 25 Pa.
Code 109.503(1 )(iii)(B)) during the permitting process (approval) of a source to determine what
treatment (if any) will be needed to ensure water served to the public will meet the safe drinking
water quality standards. Federal safe drinking water regulations have no such source water
approval requirements.
We agree that 40 C.F.R Parts 142.23 and 141.24 require entry point safe drinking water
compliance monitoring to represent all sources. Title 25 Pa. Code 109.303(a)(4) states that
samples for determining compliance with MCLs for organic contaminants listed by the EPA under
40 CFR 141.61 (relating to maximum contaminant levels for organic contaminants) and inorganic
contaminants listed by the EPA under CFR 141.62 (relating to maximum contaminant levels for
inorganic contaminants) and with the special monitoring requirements for unregulated
contaminants under § 109.302(f) shall be taken at each entry point to the distribution system after
an application of treatment during periods of normal operating conditions. If a system draws
water from more than one source and the sources are combined prior to distribution, the system
shall sample at the entry point where the water is representative of combined sources being used
during normal operating conditions.
We strongly disagree with the statements on pages 1, 4 and 5 indicating that PAD WIS does not
determine MCL compliance on analytical results submitted for emergency, reserve, interim, and
seasonal entry points. This is incorrect in that PADWIS determines MCL compliance on all entry
point analytical results submitted to PADEP regardless of the entry point availability code in
PADWIS (e.g., emergency).
Only monitoring compliance determinations for emergency, reserve, interim, and seasonal entry
points are not automated in PADWIS. All MCL compliance determinations are automated. The
reason monitoring compliance determinations are not automated for these non-permanent entry
points is that they generally are not used for many years. Automating PADWIS to look for
routine monitoring on entry points that are not serving water to the public would result in the
generation of thousands of erroneous monitoring violations.
When analytical results are submitted to PADEP for a non-permanent entry point, PADWIS will
automatically determine MCL compliance for the entry point. When PADWIS determines that an
MCL violation has occurred and the field staff validate it, the violation will be automatically
transmitted to EPA. The decision is left with PADEP field staff whether to require entry point
monitoring of these non-permanent sources before the source is used and to set the monitoring
frequency in PADWIS.
There are specific situations that occur with sources that cannot be addressed by setting PADWIS
to automatically and indiscriminately require routine monitoring of non-permanent entry points.
As stated in our response to OIG questions of August 27, 2001, PADEP field staff may wish to
set initial entry point monitoring on a more frequent basis than normally required due to
circumstances such as a potential source of contamination since the source was first permitted.
This is why our guidance states that monitoring at entry points for emergency and reserve sources
is "at the discretion of' PADEP staff.
29
Report Number 2002-P-00007

-------
OIG states on page 3 of the Report that PADEP officials did not believe they were required to
report to EPA an instance of dangerous drinking water levels because compliance monitoring had
already been performed at the entry point when a permanent but not emergency water source was
in use. We believe OIG staff are confusing automated compliance determinations in PADWIS
with EPA reporting requirements.
PADWIS can only be automated to determine monitoring compliance at entry points since
monitoring at individual source water locations is not a requirement for compliance
determinations under the Safe Drinking Water regulations. Therefore, staff would not be alerted
by PADWIS of a monitoring violation if a system did not collect an additional sample after
bringing another source online during a monitoring period in which an entry point sample had
previously been analyzed and entered into PADWIS.
Staff should track this type of additional entry point monitoring manually and require the certified
laboratory to report the analytical data on SDWA forms in order for PADWIS to determine
compliance with the Safe Drinking Water regulation MCLs. Any MCL violations would then be
reported to EPA from PADWIS. When analytical data for entry points is entered into PADWIS,
MCL compliance determinations are made by PADWIS regardless of source code availability or
when during the monitoring period the sample is collected.
On page 4 of the Report, OIG indicates that instances of safe drinking water levels being
exceeded are only reported to EPA at the State's discretion. PADEP disagrees with this
statement. Instances of safe drinking water levels being exceeded are reported to EPA when the
exceedance results in an MCL violation, as per EPA reporting instructions (see Consolidated
Summary of State Reporting Requirements for the Safe Drinking Water Information System
(SDWIS)).
As stated previously, an exceedance of an MCL is not a violation of the safe drinking water
regulations if the water is not being served to the public. Water systems may conduct "additional
monitoring" of reserve sources prior to use to determine if treatment is necessary in the event the
source will be needed. However, this is not an MCL violation if the reserve source is not being
used to provide water to the public at the time of the monitoring.
Compliance with the chemical contaminants of the Safe Drinking Water regulations is based on
more than one sample collected at an entry point. IOC MCL violations occur if the average of the
original sample and a check sample collected within 24 hours of the original exceed the MCL
value. For VOCs an MCL violation will not occur unless the running annual average of all
samples collected over 4 quarters exceeds the MCL value.
PADEP disagrees with the statement on page 4 of the Report, which states that all instances in
which drinking water standards are exceeded during additional monitoring should be reported to
EPA. For the record, the statement from PADEP personnel was that all instances in which an
MCL violation occurs should be reported to EPA. Reporting the exceedance of a drinking
water standard without an MCL violation is not an EPA reporting requirement (see Consolidated
Summary of State Reporting Requirements for the Safe Drinking Water Information System
(SDWIS)).
30
Report Number 2002-P-00007

-------
PADEP agrees with the OIG assessment that PADEP's data management drinking water source
availability definitions could be more clearly worded. Before PADEP clarifies its PADWIS
guidance, EPA needs to expand their SDWIS data management source availability codes,
including adding a source availability code of "abandoned". Recent information in the August
2001 edition of the EPA Information Management Update bulletin indicates that EPA is already
in the process of updating source availability codes to have an activity status of active,
deactivated, etc. In the interim, PADEP staff have changed all 206 source availability codes in
PADWIS that were identified as being incorrect, which was acknowledged by the OIG audit team
during their review.
On page 5 of the report, OIG indicates that some analytical results conducted by PADEP certified
drinking water laboratories are not being entered into PADWIS since they are not reported on a
Safe Drinking Water Act (SDWA) form even though PADEP laboratory reporting guidance
indicates all analyses conducted by a certified laboratory should be submitted to PADEP on
SDWA forms. The review of 27 water systems did indicate that some source water analytical
results conducted by PADEP certified drinking water laboratories were not entered into PADWIS
because the results were not submitted on SDWA forms. PADEP agrees that PADEP laboratory
reporting guidance does require the reporting of all analytical results conducted by a certified
drinking water laboratory to be submitted on SDWA forms.
The analytical results in question from the review relate to additional monitoring of sources that
were not in use and, therefore, not conveying water to the public. Since this data pertains to
sources of water that may be used in the future, the analytical results should have been reported
on SDWA forms and entered into PADWIS in order to maintain a historical record of each
potential water supply source. The review indicated the information is currently maintained in
hard copy form in the PADEP public water supply permit files. Although these inactive source
water analytical results were not entered into PADWIS, a compliance determination was not
required since the water was not being served to the public. The lack of this additional source
monitoring data in PADWIS did not compromise the public health in any way.
On page 5 of the Report, OIG assumes that monitoring results other than those used for MCL
compliance determination purposes do not undergo data quality checks. PADEP disagrees with
this assumption. All certified drinking water laboratories in Pennsylvania undergo periodic
evaluations of their analytical methodologies to ensure they are using those methods that are
approved for use. It is true that PADWIS will place sample results into a "reject file" if the
laboratory analysis is not conducted according to the approved laboratory method. However, the
field staff are notified of these rejected samples, which allows them to respond to analytical results
of concern and to request additional samples using the approved analytical method. Contrary to
the OIG statement, these procedures are a data quality check that the certified laboratory did
indeed use the approved analytical methodology
On page 5 of the Report, OIG indicates that PADEP does not report exceedances detected at
entry points for emergency or reserve sources if it has already conducted compliance monitoring
for that entry point. Therefore, if the public water system later detects an exceedance, such as
31
Report Number 2002-P-00007

-------
after an emergency source is put into use, PADEP will not report the exceedance to EPA. Again,
we believe OIG staff are confusing automated compliance determinations in PADWIS with EPA
reporting requirements.
As stated previously, staff should track this type of additional entry point monitoring manually and
require the certified laboratory to report the analytical data on SDWA forms in order for
PADWIS to determine compliance with the Safe Drinking Water regulation MCLs. Any MCL
violations would then be reported to EPA from PADWIS. When analytical data for entry points
is entered into PADWIS, MCL compliance determinations are made by PADWIS regardless of
source code availability or when the sample is collected.
On page 6 of the Report, OIG states that PADEP does not notify EPA of all drinking water
sources, because EPA does not explicitly require this information for its SDWIS inventory. OIG
goes on to state that EPA needs this information since drinking water supplies can be subject to
natural or environmental disasters, as well as bioterrorism. PADEP agrees, but would like to
clarify why some data is not currently reported to EPA.
Under the Pennsylvania Surface Water Filtration Rule, many water systems decided to abandon
their unfiltered surface water sources rather than install filtration treatment, which can be rather
expensive. Because SDWIS does not have an availability source code of abandoned, sources in
PADWIS with an availability code of abandoned were not sent to EPA to avoid data management
problems. Last year at EPA's request, we reported these abandoned sources to EPA but had to
assign an availability source code of "other" because SDWIS does not have an abandoned source
availability code. Although abandoned unfiltered surface water sources are not subject to the
Surface Water Filtration Rule, these abandoned surface water sources are now appearing
incorrectly on SDWIS reports as unfiltered surface water sources.
Our on-going efforts to deal with the threat of terrorism and EPA's need for source information
should not be tied together with this review as they are not relevant to the issues originally raised.
PADEP has been working closely with EPA Region III staff, the FBI, the Federal and
Pennsylvania Emergency Management Agencies, ASDWA, and others to ensure that all inventory
information and information on activities being conducted by PADEP to improve counter-
terrorism efforts is available, if needed.
In summary:
PADEP disagrees with the OIG recommendation that the EPA Region 3 Administrator require
PADEP to align compliance monitoring and reporting procedures and guidance with Federal and
State drinking water regulations. The OIG audit failed to show any discrepancies as documented
by our previous comments.
PADEP disagrees with the OIG recommendation that the EPA Region 3 Administrator require
PADEP to clarify data management procedures to ensure the reporting of maximum contaminant
level exceedances for all sources of public drinking water. As stated previously, EPA reporting
guidelines do not require the reporting of maximum contaminant level exceedances, only
maximum contaminant level violations.

PADEP agrees with the OIG recommendation that the EPA Region 3 Administrator should
review compliance reporting procedures for other Region 3 States, as this should be an ongoing
requirement of EPA oversight of the State Safe Drinking Water programs.
PADEP conditionally agrees with the OIG recommendation that the EPA Assistant Administrator
for Water should revise SDWIS guidance on the term "active" and source availability codes, as
well as require that States report to EPA all designated sources, so long as the guidance and
requirement is conveyed to all EPA Regions and administered uniformly across the nation. This
guidance should only apply to data management reporting and not change implementation of the
safe drinking water regulations.
PADEP agrees that compliance monitoring is an important part of the Safe Drinking Water
Program, but it is only one part of a much greater public health protection effort. Pennsylvania has
invested many years of effort in a much more comprehensive approach to ensure that
infrastructure, department and water system personnel, operational procedures, public
involvement, compliance monitoring, data management, and other activities are all "optimized" in
a holistic effort to protect public health. It is misleading for the OIG to conclude that public
health is jeopardized simply because some small amount of data may not be transmitted to EPA.
The findings in the Report need to be presented in the context of the PADEP's Safe Drinking
Water Program with the built-in multiple barriers that we have put into place to protect public
health in Pennsylvania.
PADEP staff routinely respond to complaints and violations of public water systems in order to
protect public health regardless of whether the information is reported to EPA. Adding more
reporting requirements will do nothing to improve our response and may adversely impact our
ability to act quickly if we must respond to a public health emergency.
Over the years, PADEP has been proactive in terms of protecting public health. Pennsylvania had
a requirement to filter all surface sources before EPA did; and, without the filtration avoidance
criteria that the federal regulations currently allow. An additional 130 filter plants were built in
Pennsylvania to treat water at systems using unfiltered surface water sources. More than 250
water systems in Pennsylvania have eliminated their unfiltered surface water sources.
Recognizing that protection of finished water from the time it is treated until it flows from a
consumer's tap is critical to protection of public health, PADEP required systems with uncovered
finished water reservoirs to cover them at the same time we required filtration of all surface
sources starting in 1988. EPA did not require finished water reservoirs to be covered until
February 16, 1999, under the Enhanced Filtration and Disinfection Rule. To date, all but two
uncovered finished water reservoirs in Pennsylvania have been covered, with the remaining two
under PADEP order to comply.
To assure that Pennsylvania's 329 filtration plants maximize public health protection for their
customers, PADEP initiated the Filter Plant Performance Evaluation (FPPE) program in 1988.
The FPPE program has resulted in optimum performance for nearly 90% of Pennsylvania's filter
plants. Over 3 million people have benefited from upgrading filter plants in response to the FPPE
program.

PADEP is also helping water systems to protect public health through the regional Partnership for
Safe Water program, which is one of only three in the nation. Currently, about 25% of the
nation's Partnership for Safe Water members are located in Pennsylvania. This voluntary
Partnership encourages water systems to conduct a self-assessment of their water system, prepare
for upcoming regulations, and optimize their treatment plants for best performance. This program
is providing improved public health protection benefits to more than 4.5 million Pennsylvanians.
These programs are essential in terms of protecting public health from the occurrence of giardia,
Cryptosporidium, and other waterborne disease organisms. Combined with our Joint
Cryptosporidium Action Plan with the Pennsylvania Department of Health, which has armed
health care providers and public water suppliers with the means to protect the public and raise
awareness about waterborne cryptosporidiosis, waterborne disease outbreaks in Pennsylvania are
a thing of the past. Pennsylvania has not had a single waterborne disease outbreak sine 1996.
But this is only part of the story. Our Engineering Services Program provides engineering
services through an outside contract consultant to water systems unable to afford such services.
This program has resulted in 24 small water systems being able to design treatment schemes to
ensure water delivered to their customers that meets safe drinking water standards. To date, 5 of
these systems have completed construction
Four grant programs, Regionalization Feasibility Studies, County Water Supply Planning,
Formation of Water Authorities, and Small Water System Consolidation Grants, are available in
Pennsylvania to help small water systems remain viable through consolidation of systems and
capital. To date, 39 regionalization studies, 20 county water supply plans, and 3 formation of
water authorities grants have been completed. A total of $5.2 million has been awarded under
these four grant programs.
The capability enhancement program has provided technical, financial and managerial expertise to
more than 33 drinking water systems across Pennsylvania. This investment has resulted in
systems on the verge of failure to once again become viable water systems.
PADEP has made a considerable resource commitment to training of operators and field staff.
Through the use of the Environmental Training Partnership's 75 peer trainers, on-going assistance
services are provided to public and privately owned drinking water systems. The Environmental
Training Partnership has provided over 20,000 hours of training annually in such courses as
Corrosion Control, Water Math, and Pumps and Pumping.
PADEP has, in cooperation with Penn State Harrisburg, completed construction of a pilot
conventional water treatment plant to help train water operators. The focal point of this
multipurpose environmental training center is a two-gallon per minute conventional water
treatment plant, complete with coagulation, flocculation, sedimentation, filtration, and all
associated instrumentation, including turbidity meters, a pH sensor, chart recorders, a display
control panel, and a personal computer. The primary purpose of this unit is for "hands-on"
operator training, with all unit process tanks constructed of clear acrylic plastic to allow visual
inspection and evaluation of process performance.

PADEP has initiated the Source Water Assessment and Protection Program (SWAPP), which will
assess all sources of public drinking water for their susceptibility to contamination. This program
is a proactive effort to prevent pollution from contaminating a water supply source, rather than
treating the contamination after the fact. A cornerstone of the SWAPP is Pennsylvania's
Wellhead Protection Program (WHPP). Under the WHPP all groundwater sources developed
after October 9, 1995, must take precautions to ensure that potential contamination of the source
is limited.
Contracts, grants and staff training are in place to assess all of the 14,000 sources at public water
systems in Pennsylvania. To date, 236 community water systems have initiated source water
assessments. Three of these systems have completed the source water assessments, which
consists of 6 steps: source delineation, source inventory, susceptibility determination, public
availability, management measures, and contingency planning.
Additional projects to support development of local source water protection include a grant with
the League of Women Voters of PA Citizen Education Fund to administer mini-grants to
coalitions of local and regional organizations involved with water resources education projects,
the lower Susquehanna pilot SWAPP project on the Swatara Creek Watershed, grants to the PA
Rural Water Association for local WHPP development, a grant to Lehigh Valley Water Suppliers
for education and promotion projects, a grant to Montana Water Center for development of a
source water protection workbook, and a source water protection grant program to support
development of local protection programs.
The PADEP Safe Drinking Water Program does much more than ensuring that the safe drinking
water regulations are followed and data indicating such is reported to EPA. We are dedicated to
protecting the public health through numerous complex programs, some of which are mentioned
above. Through the efforts of the PADEP staff these programs have made a dramatic
improvement in the quality of water delivered to consumers in Pennsylvania

OFFICE OF
WATER
MEMORANDUM
SUBJECT: Draft Report:
Pennsylvania's Reporting of Safe Drinking Water Violations
Draft Report No. 2001-000398
FROM: G. Tracy Mehan, III
Assistant Administrator
Office of Water (4101)
TO:	Carl A. Jannetti
Divisional Inspector General for Audit
Mid-Atlantic Division (3AI00)
Thomas C. Voltaggio
Acting Regional Administrator
Region 3 (3DA00)
Thank your for your memorandum of November 26, 2001 transmitting the Draft Report
entitled "Pennsylvania's Reporting of Safe Drinking Water Violations" (Draft Report No. 2001-
000398). Responses to Findings 4 and 5, as requested in the report are included in this
memorandum.
Response Actions
Finding 4: Revise SDWIS guidance to further clarify what "active" means as it applies to
SDWIS reporting requirements and include a discussion of source availability
codes
Proposed Action: The Office of Ground Water and Drinking Water (OGWDW) will evaluate
the need for additional guidance to clarify what "active" means regarding sources of drinking
water. We will do this by conducting a conference call with regional offices to determine if the
problem identified in Pennsylvania exists in other states. If we find the problem to be
widespread, we will provide guidance to ensure that appropriate actions are taken to protect
public health. If we find the problem exists only in a few states, individual technical assistance
and guidance will be provided by the appropriate regional office.

Report Number 2002-P-00007

-------
Responsible Party: Jeffrey Bryan, OGWDW's Associate Branch Chief for the Infrastructure
Branch, will be responsible for coordinating and facilitating the proposed actions including
conducting the conference call with the regions and making recommendations to this office
regarding the implementation method for any corrective actions.
Completion Date: The regional conference call will be held in January 2002. A schedule for
other actions that may be required, should any be needed, will be developed after the conference
call.
Finding 5: Require states to report to EPA all designated sources of drinking water.
Proposed Action: OGWDW will evaluate the need for requiring states to report all sources of
drinking water. The Public Water Supply Supervision (PWSS) program is managed through a
partnership of EPA and state primacy programs. Information to be routinely reported to EPA,
other than that specifically identified in regulation, is evaluated and recommended by the
State/EPA Data Sharing Committee. If it is found that intermittent and emergency sources of
drinking water data should be maintained by EPA, we will work with the Committee to
determine the best method for implementation.
Responsible Party: Jeffrey Bryan, OGWDW's Associate Branch Chief for the Infrastructure
Branch, will be responsible for coordinating and facilitating the proposed actions.
Completion Date: March 29, 2002.
Thank you for the opportunity to provide comments on the Draft Report. We look
forward to working with you in the future to improve the information maintained on the drinking
water program. Any questions should be directed to Jeffrey Bryan at 202-564-3942.
