Why We Did This Review

We conducted this evaluation
to assess the U.S.
Environmental Protection
Agency's (EPA's) oversight
and assistance of tribal
community water systems
(CWSs), and to independently
evaluate water quality at
selected drinking water
systems.
Background
EPA, rather than the States,
has the responsibility for
protecting human health and
the environment on tribal
lands. Approximately 600
tribal CWSs serve an
estimated 622,000 people.
EPA staff members provide
these systems with technical
and other assistance so that
tribal CWSs maintain
compliance with Safe
Drinking Water Act
requirements.

Congressional and Public
Liaison at (202) 566-2391.

EPA Assisting Tribal Water Systems
but Needs to Improve Oversight
 What We Found
Tribal drinking water sample results in EPA files indicate that drinking water
supplies consistently met regulatory requirements.  Regional EPA staff also made
correct compliance decisions with sample results that tribal CWSs provided.
However, internal control deficiencies existed in administering EPA's oversight
of tribal CWSs in two of the five regions we reviewed. To varying degrees, tribal
drinking water records in four of the five regions were incomplete due to a failure
to maintain oversight of system operations and/or poor records management.

We sought to verify, through independently collected samples, that these tribal
CWSs did not exceed drinking water regulatory limits. Of the approximately
2,300 independent samples analyzed, only 7 were above the limits. In those
cases, we informed regional staff and water system operators, who then took
follow-up actions.
 What We Recommend
We recommend that the Assistant Administrator for Water (1) establish national
and regional tribal drinking water program Standard Operating Procedures in
coordination with regional offices; (2) require Region 2 to submit a plan that
corrects deficiencies in how it currently implements its tribal drinking water
program, including those identified in this report; and (3) direct regions to issue
monitoring and reporting violations, take appropriate enforcement actions against
tribal CWSs with health-based violations or who fail to  monitor or submit
monitoring reports, and enter violations into the Safe  Drinking Water Information
System.

The Agency agreed with our recommendations.

                                  Introduction
Purpose
             We conducted this evaluation to assess the U.S. Environmental Protection
             Agency's (EPA's) oversight and assistance of tribal community water systems
             (CWSs), and to independently evaluate water quality at selected systems. We
             focused on tribal CWSs because they are among the few systems that EPA
             regions, rather than States, oversee. We sought answers to two questions:

             1. What methods does EPA use to oversee compliance at community water
                systems on tribal lands and how are data from these systems verified?
             2.  How well do community water systems on tribal lands monitor and report
                 compliance with national primary drinking water standards?
Background
             EPA, rather than State government, has the responsibility for protecting human
             health and the environment on tribal lands. The 1984 EPA Indian Policy
             establishes nine principles to guide the Agency as it implements congressionally-
             mandated responsibilities on tribal lands.  The principles emphasize working
             directly with tribal governments on a government-to-government basis,
             recognizing tribal governments as primary parties for environmental policy
             decisions, and encouraging/assisting tribes to assume regulatory and program
             management responsibilities for their lands.

             The Safe Drinking Water Act (SDWA) creates an umbrella of responsibilities
             aimed at safeguarding the drinking water of the population. EPA's regional
             offices implement the SDWA1 for approximately 600 tribal CWSs, serving an
             estimated 622,000 people.2  Tribal CWS operators collect water samples for
             analysis by certified laboratories and then report those results to EPA.  The Office
             of Ground Water and Drinking Water (OGWDW) relies on drinking water staff
             located in the regions to:

             •   Determine whether tribal CWS sampling results are within regulatory limits,
             •   Review and approve tribal CWS monitoring waiver applications,
  40 CFR (Code of Federal Regulations) 141.2 defines "State" as the agency of the State or tribal government that
has jurisdiction over public water systems. During any period when a State or tribal government does not have
primary enforcement responsibility pursuant to Section 1413 of SDWA, the term "State" means the Regional
Administrator, U.S. EPA.
2 The Navajo Nation has authority to implement SDWA for 140 tribal systems and these were not evaluated in this
study.

                                                                                08-P-0266


              •   Provide assistance to tribal CWSs to prevent violations from occurring, and
              •   Take enforcement actions when drinking water regulations are violated.

              EPA drinking water staff may issue violations when (1) a tribal CWS does not
              conduct required monitoring or report sampling results or (2) a water sample
              result exceeds the established maximum contaminant level (MCL).  According to
              the 1984 Indian Policy, EPA will work cooperatively with tribes to achieve
              compliance. EPA considers direct enforcement action if there is a significant
              threat to human health and the environment, if compliance is not achievable in a
              timely manner, and if EPA cannot utilize other alternatives to correct the problem.

              EPA has the authority to grant monitoring waivers or reduce monitoring
              requirements if there is a limited likelihood of a contaminant being in a tribal
              CWS's source water.3 Once a waiver is granted, the system is excused from
              monitoring for a specified period of time. This reduces  expenses for tribal CWSs
              while maintaining human health protections. To retain consistency in the
              decision-making process, one region we reviewed relies upon written guidelines
              to evaluate monitoring waiver applications from tribal CWSs. Region 9 has a
              detailed wavier application procedure for tribal CWSs requesting reductions in
              monitoring requirements.

              EPA also implements technical and compliance assistance programs to help tribal
              CWSs protect human health and reduce incidents of drinking water violations.
              These programs include operator training, sanitary surveys, source water
              protection, technical assistance, and infrastructure grants. In the past 11 years, the
              Drinking Water State Revolving Fund Set Aside grant program has allotted
              approximately $135 million to improve tribal CWS infrastructure.

              The Agency works  to measure the effects of its enforcement and compliance
              assistance programs by tracking how many tribal CWS customers consume water
              that meets all drinking water standards.  In the 2006 - 2011 Strategic Plan, EPA
              established a national goal that 86 percent of tribal CWS customers will drink
              water that meets all health-based standards by 2011. Compliance assistance
              efforts of EPA and  other organizations help achieve this national performance
              goal. The Indian Health Service, through collaboration  with tribes, identifies
              CWS infrastructure needs and enters these data in the Sanitation Deficiency
              System. The Bureau  of Reclamation provides technical and financial assistance
              to tribal systems in  the Western United States.  EPA uses the information about
              health-based violations reported in the Safe Drinking Water Information System
              (SDWIS) to track and report progress to Congress on the performance of all water
              systems at a national and regional level.
3 40 CFR 141 outlines the monitoring requirements for the drinking water contaminants regulated by EPA. It also
describes the conditions under which a monitoring waiver can be issued by the "State" and under which "States" can
reduce monitoring requirements.

Noteworthy Accomplishments
              EPA has completed a number of noteworthy activities in its efforts to assist tribal
              CWSs.  The following is a summary of some of their most recent
              accompli shments.

              •   The OGWDW issued the Tribal Drinking Water Operator Certification
                  Guidelines in May 2005 to help assess, track, and address certification needs
                  on tribal lands.

              •   The OGWDW developed a new Website that provides a consolidated list of
                  drinking water classroom and on-line training opportunities that may be of
                  interest to tribes and tribal operators.

              •   In June 2007, EPA launched the new Tribal Portal, a Website that provides
                  users with consolidated information about EPA tribal policies, contacts,
                  programs, and funding sources.

              •   Starting in 2003, an EPA contractor performed data verifications of the tribal
                  drinking water records in the regions we visited.
Scope and Methodology
              We employed a variety of methods to evaluate the performance of tribal CWSs
              and the processes used by EPA to oversee compliance of these systems. We
              selected 25 tribal CWSs with no reported violations between 1997 and May 2007
              from the SDWIS database (see Figure 1-1 and Appendix A, Table A-l).

                                                                                 08-P-0266
              We requested and reviewed the monitoring results for national primary drinking
              water contaminants submitted by the 25 tribal CWSs to regional staff (see
              Appendix A, Table A-2, for the data we requested).  We conducted interviews
              with personnel from Headquarters, Regions 1, 2, 4, 5, and 8, and tribal CWSs
              about compliance assistance,  operation and maintenance challenges, alternate
              sources of assistance outside EPA, and individual monitoring requirements. We
              also interviewed drinking water staff from Region 9 because this Region oversees
              the largest number of tribal systems.

              In addition, we contracted with an environmental services company to collect and
              analyze drinking water samples from these systems.  Personnel from the Office of
              Inspector General (OIG) accompanied the contractor on site visits.  We collected
              samples from both the point of entry and the distribution system at  19 of the 25
              tribal CWSs.4 At five systems we only collected samples from the point of entry.
              This situation was  due to time requirements for transporting samples to the
              laboratory or to a lack of access to sampling points in the distribution system. At
              one system we did not collect any samples because it permanently closed prior to
              our site visit. Appendix A, Table A-3, contains a list of the tests we did not
              perform at the tribal CWSs.

              A laboratory analyzed the samples for contaminants regulated under EPA's
              National Primary Drinking Water Standards with the exception of lead and
              copper.5 EPA protocols were followed for sample collection and analysis.  These
              results are for information purposes and cannot substitute for regular drinking
              water sampling requirements.  In cases where these results were above regulatory
              limits, we contacted regional  staff and water system operators to discuss follow-
              up actions.

              Due to the small sample size and methods used to select the tribal CWSs, the
              results of this evaluation cannot be used to generalize drinking water quality at
              other tribal systems. The results of our independent samples were for information
              purposes and did not substitute for regular drinking water sampling requirements.
              We conducted this review in accordance with generally accepted government
              auditing standards.  Those standards require that we plan and perform the review
              to obtain sufficient, appropriate evidence to provide a reasonable basis for our
              findings and conclusions based on our objectives. In addition, we discussed
              internal controls regarding tribal water system compliance data.6 We believe that
              the evidence obtained provides a reasonable basis for our findings and
              conclusions based upon our objectives.  We performed our review from June
              2007 to May 2008.
4 The point-of-entry sample is a type of water sample taken after treatment and before reaching the first consumer.
The distribution system is a network of pipes leading from a treatment plant to customers' plumbing systems.
5 The team did not include lead and copper in the scope of this evaluation because sampling requires advanced
planning to coordinate site visits with homeowners.
6 Internal controls are used to prevent fraud, waste, and abuse of program/agency assets. It also includes the
processes for planning and directing program operations and systems for measuring, reporting, and monitoring

              EPA Needs to Improve Oversight of
                 Tribal  Drinking Water Systems

            Records of tribal drinking water sample results in EPA files indicate that drinking
            water supplies consistently met regulatory requirements. Regional drinking water
            staff also made correct compliance decisions with the sample results provided by
            tribal CWSs.  However, internal control deficiencies occurred in administering
            EPA's oversight of tribal CWSs in two of the five regions we reviewed.  To
            varying degrees, tribal drinking water records in four of the five regions were
            incomplete due to a failure to maintain oversight of system operations and/or poor
            records management.

EPA Correctly Determined Compliance for Monitoring Reports in
Regional Files

            Our examination of tribal  CWS historical data in regional files (see Appendix A,
            Table A-2) confirmed that EPA drinking water staff interpreted sample results to
            draw correct compliance determinations. However, regions were only able to
            provide us with  all of the data we requested for 7 of the 25 tribal CWSs in this
            evaluation. Because regional files were missing approximately 18 percent of the
            sample results requested (861 of 4,910 sample results), we were unable to
            evaluate EPA's  performance in these cases. Figure 2-1 summarizes the amount of
            requested compliance records we collected as well as the missing data by region.

          We identified three reasons why the records were missing from EPA files:

             1) Tribal CWSs failed to monitor for contaminants,
             2) State involvement in tribal CWS oversight prevented monitoring
                information from reaching the region, and
             3) EPA drinking water staff members were unable to locate records or
                records were lost over time.

          For the approximately 4,000  monitoring results we collected from EPA's files, we
          found that EPA staff made no errors in determining compliance with drinking
          water regulations.  For the results we reviewed, tribal CWSs submitted sampling
          results in prescribed timeframes in all but two occasions. In Region 5, two tribal
          CWSs submitted radionuclide sample results prior to the June 2000 through
          December 2003 grandfathered period.  The samples, taken outside the prescribed
          sampling period, were within regulatory limits.

Regions Varied in Oversight of Tribal Drinking Water Systems

          The five regions varied in the quality of oversight they provided to tribal CWSs.
          Region 1's records were complete except for missing synthetic organic chemical
          (SOC) samples caused by an error in instructions from the Region to the tribal
          system.  Regions 5 and 8 provided complete  or near-complete records for tribal
          CWSs located in those regions.  Drinking water staff in these Regions attribute
          their success to operator training programs and to regular communication with
          them about  sampling requirements.  We found greater amounts of missing records
          in Regions 2 and 4. In Region 2, tribal CWSs failed to monitor for certain
          contaminants. Moreover, Region 2  chose not to enter known monitoring
          violations into SDWIS and did not conduct enforcement actions against the
          systems that committed these violations. In Region 4, State participation in tribal
          CWS oversight prevented monitoring information from reaching the Region.
          Without these sampling results, EPA was unable to determine compliance with
          drinking water regulations.

          Region 2 Did Not Issue Monitoring Violations to Tribal Systems or
          Update SDWIS

          Region 2 is missing approximately 15 percent of the drinking water sample results
          we requested for 6 tribal CWSs (169 of 1,110 records).  See Appendix B, Table
          B-2, for a summary of the records missing from Region 2 files. Region 2 staff
          said the missing data are a result of water systems failing to monitor for regulated
          contaminants over many compliance periods. For all six tribal CWSs we
          reviewed, Region 2 did not take enforcement actions when these systems failed to
          collect samples and submit results for compliance determination. Region 2 also
          did not report these violations into SDWIS, which stores information about
          drinking water systems.

                                                                                08-P-0266
              While drinking water regulations require water systems to annually monitor for
              nitrate, Region 2 staff confirmed that regional files are missing nitrate results for
              four of the six tribal CWSs for the 2004, 2005, and 2006 compliance periods.
              This required test is important because excessive nitrate levels in children can
              interfere with the oxygen-carrying capacity of their blood. Based on sampling
              results from nearby systems using the same aquifer, regional personnel believed
              that the quality of drinking water in these four tribal CWSs was good. Although
              none of these systems tested above the established MCL for nitrate in our
              independently collected samples, regulations require that regions take
              enforcement actions when water systems do not monitor and report results to
              EPA.

              Moreover, we believe customers are likely unaware that their systems failed to
              monitor for nitrate and other contaminants because these systems never provided
              their customers with annual Consumer Confidence Reports (CCRs) in 2004, 2005,
              or 2006, as required under SDWA.7 Had the water systems issued these annual
              reports, they would have also been required to detail steps to correct monitoring
              problems in the future. Region 2 confirmed that it also did not take enforcement
              actions against the systems that failed to issue CCRs but plans to work with them
              to ensure that tribal customers receive CCRs detailing 2007 water system
              performance.

              While we found incidents of monitoring and reporting problems with tribal CWSs
              in Region 2,  EPA staff informed one system of its concerns. In May 2007,
              Region 2 notified the Shelton Park CWS about the physical condition of its
              system, positive coliform bacteria samples, and handling and disposing of
              household chemical waste. In a letter, Region 2 stated, "the well used to supply
              water to the residents of Shelton  Park is highly vulnerable to significant
              contamination from both human  and animal fecal waste and we (Region 2) are
              concerned that the water is not being adequately disinfected."

              Region 2 personnel reported to us that while concerns have been expressed to
              Shelton Park, monitoring violations for this and other tribal CWSs have not been
              recorded in SDWIS for the past 10 years. Region 2's Drinking Water Section
              Chief reported that this stems from an understanding within the tribal drinking
              water program that staff would focus its  resources on compliance assistance rather
              than enforcement actions.

              In addition to missing enforcement actions in SDWIS, we found water system
              inventory errors with tribal CWSs.  Inventory data, such as water source and
              population size, are information that regions use to determine sampling
              requirements. If this information is incorrect, it can affect EPA's oversight. For
              example, SDWIS identifies the Cattaraugus-Richardson Road tribal system and
7 40 CFR 141.51 outlines the information CWSs must include in their annual CCRs.  In addition to distributing
copies to customers, tribal CWSs must mail a copy of the report to the appropriate EPA region and certify that the
report was delivered to customers by the July 1st deadline.

Cattaraugus-Erie County system as two distinct CWSs. Region 2 staff reported
that the Cattaraugus-Richardson Road system is actually part of the larger
Cattaraugus-Erie County system.

Region 4 Not Informed of Oversight Activities Taken by Mississippi

Region 4 is missing approximately 51 percent of the drinking water sample results
we requested for 5 tribal CWSs (508 of 1,001 records). The tribal CWSs in
Mississippi have an atypical relationship with the State's drinking water program.
While Region 4 has informally accepted regulatory decisions made by the State
for these water systems, it is unaware of the extent of Mississippi's regulatory
role.

Both Region 4 and the Mississippi State Department of Health (MSDH) regulate
the four water systems operated by the Mississippi Band of Choctaw Indians
(MBCI).  As the primary regulatory authority, Region 4 can issue waivers to these
tribal CWSs and/or reduce monitoring requirements based on the results of
monitoring samples. Because these four tribal CWSs participate in Mississippi's
sampling program, MSDH also serves a regulatory role by creating monitoring
schedules, issuing monitoring waivers, and reducing monitoring requirements for
regulated drinking water contaminants based on SDWA requirements.

Region 4 accepts monitoring waivers issued by MSDH for these tribal CWSs
because Mississippi has an EPA-approved drinking water and waiver program.
Drinking water regulations do not preclude Region 4, as the primacy agency for
tribal CWSs, from honoring waivers issued by another primacy agency, such as
MSDH. Under drinking water recordkeeping requirements, Region 4, as the
primacy agency for tribal CWSs, is required to keep documentation of waivers
and decisions to reduce monitoring requirements in its files for 12 years. Region
4 could not provide documentation for these regulatory decisions made  by
MSDH, which accounts for 79 percent of data we categorize as missing (401 of
508 pieces of monitoring data) (see Appendix B, Table B-3). If Region 4 had
documentation of MSDH's regulatory decisions, we would only categorize
approximately 11 percent of the  data we requested as missing.

Region 4 and MSDH both include the four tribal CWSs in their versions of the
SDWIS database, but do not reconcile the violation and enforcement-related
information reported in the individual databases. As a result, discrepancies
occurred between the two data systems.  For example, according to the MSDH
information uploaded to SDWIS, the Pearl River CWS had a health-based total
coliform violation in August 2005. However, Region 4's database did not contain
this violation until after we reviewed SDWIS data in May 2007.  Region 4's
database shows that Pearl River achieved Federal compliance for this violation in
September 2005.

             Regions 1, 5, and 8 Consistently Tracked Monitoring Requirements

             With minor exceptions, we found that Regions 1, 5, and 8 had generally good
             oversight and records management practices.  Because of this we were able to
             confirm that the regions made correct compliance determinations for the tribal
             CWSs in our sample.  Region 1's files were complete except for second
             consecutive quarterly samples for Synthetic Organic Chemicals for the
             compliance periods 1999-2001, 2002-2004, and 2005-2007.  In Region 5,
             29 of 1,203 sampling results were missing for the 7 tribal CWSs in our sample.
             Region 8 provided complete compliance histories for the six tribal CWSs in our
             sample.  See Appendix B for additional details about missing data.

OIG Water Sample Results within Regulatory Limits

             We sought to verify, through independently collected samples, that these tribal
             CWSs did not exceed MCLs for national primary drinking water regulations.
             Nearly all the water samples we collected were below the MCLs established in
             the drinking water standards and were consistent with the data we reviewed from
             regional files. Of the approximately 2,300 independent samples analyzed, only 7
             were above regulatory limits.  In the cases where results were above these limits,
             we informed regional staff (in Regions 5 and 8) and water system operators, who
             then took follow-up actions.  See Table 2-1 for a summary of sample results and
             follow-up actions.

              Once we alerted EPA regional staff and water system operators of the six positive
              coliform samples, the systems collected and analyzed additional samples. A
              single coliform exceedance does not constitute a violation of the drinking water
              standard. The results from these re-tests showed an absence of total coliform in
              the water.

              The other exceedance of a drinking water standard occurred at the American
              Horse Creek CWS in South Dakota.  The sample result tested above the
              established 0.010 mg/L MCL for arsenic at 0.014 mg/L. Prior to the
              implementation of the new standard in 2006, the MCL for arsenic was 0.050
              mg/L. Unrelated to these results, Region 8 compliance staff had already placed
              the water system on an increased monitoring schedule, as is required by the new
              arsenic drinking water regulation.  According to the water system manager,
              American Horse Creek will be connected to a new source by the end of 2009.

EPA and Other Organizations Assist in Tribal Water System
Compliance

              In addition to its regulatory oversight responsibilities, EPA implements technical
              and compliance assistance programs and collaborates with other organizations so
              that tribal CWSs can maintain or improve their performance.  In EPA's most
              recent strategic planning document, the 2006- 2011 Strategic Plan., the Agency
              committed to working with other Federal agencies to support developing drinking
              water and wastewater infrastructure in Indian country.8 All six regions we
              interviewed reported utilizing services of other Federal agencies and/or non-profit
              groups to improve tribal CWSs' infrastructure and performance.

              Regions helped tribal CWSs  maintain compliance with monitoring requirements
              by providing schedules for sample collections; assessing the technical,
              managerial, and financial capacities of water systems; conducting operator
              training courses; and answering technical questions about regulations.
              While water system operators told us they were generally satisfied with the
              assistance EPA provides, tribal water staff expressed a desire for more training
              assistance.

              EPA's collaboration with its  contractors and Federal partners also help to improve
              tribal CWS performance.  EPA funds State Rural Water Association affiliates to
              provide training and technical assistance to small systems, including tribal  CWSs.
              Three of the six regions we interviewed told us they consider information in the
              Indian Health Service's Sanitation Deficiency System when prioritizing tribal
 EPA has committed to reducing the number of tribal households that do not have access to safe drinking water and
basic sanitation by 50 percent by 2015. This commitment is in response to the developmental goals agreed to at the
2002 United Nations World Summit on Sustainable Development held in Johannesburg, South Africa. EPA works
with the following Federal agencies to improve tribal access to safe drinking water and basic sanitation: Department
of Agriculture, Department of Health and Human Services, Department of Housing and Urban Development, and
Department of the Interior.

              drinking water system infrastructure needs and Drinking Water State Revolving
              Fund infrastructure grants.

              Even with EPA's and other organizations' assistance provided to tribal CWSs,
              many of the water system managers we interviewed told us that their systems face
              similar challenges as operators at other small water systems have described to us
              in the past.9 Some of these include the operators' desire for more training and
              technical assistance, water rates that do not cover the costs of operation,
              customers not paying their bills, governing bodies' reluctance to pay for
              infrastructure improvements, and low pay for water operators. However, based
              on our review of regional files and independent samples, the tribal CWSs we
              reviewed are able to provide their customers with drinking water that meets
              Federal standards.

Conclusions and Recommendations

              The six regions whose tribal drinking water programs we reviewed provide tribal
              CWSs with a variety of technical and other assistance activities that help these
              systems provide safe drinking water to the public.  Our independent samples show
              that, at the time of our site visits, tribal customers received drinking water that
              met health-based standards. Good source water, attentive water system staff, and
              assistance from EPA and others were noted as helping tribal  CWSs with their
              performance.  But incomplete compliance records and failures to issue violations
              point to regional internal control deficiencies. Internal  controls are an important
              safeguard for ensuring that systems operate as intended. Deficiencies in these
              controls may indicate that the systems are vulnerable to failure, resulting in
              increased risk to public health. To improve its internal  controls, EPA
              Headquarters needs to clearly communicate to regions what is required and what
              is allowed in terms of their oversight of tribal CWSs.

              Region 4 needs to increase  communication and coordination with MSDH for
              tribal CWSs operated by the MBCI. While drinking water regulations  do not
              prevent Region 4 from honoring decisions made by MSDH to reduce monitoring
              or issue waivers, without documentation we cannot determine if Region 4 staff
              made timely and accurate compliance  determinations. Greater coordination and
              communication would reduce the amount of missing compliance data in
              Region 4's files, as well as improve the accuracy and completeness of SDWIS
              entries. Implementing a formal waiver policy, similar to Region  9's Tribal
              Drinking Water Monitoring Waiver Program, would help to ensure that MSDH
              issues waivers and reduces  monitoring requirements based on statutory
              regulations.

              Region 2's decision to not issue monitoring violations is counter to Agency
              oversight responsibilities under SDWA.  This undermines the transparency that

              should exist between water systems and their customers, especially since water
              systems are required to report all violations in their annual CCRs. The absence of
              monitoring violations in SDWIS also affects EPA's overall efforts to improve the
              completeness of this database.  This database, which is also available to the
              public, does not currently reflect the  compliance history for all six tribal  CWSs
              we reviewed in Region 2.  EPA needs this database to contain accurate and
              complete drinking water violation data so that it can monitor its progress at
              meeting performance goals and report complete and unbiased information to

              issues is a serious oversight.

              The Office of Water needs to address the issues identified in Regions 2 and 4 at a
              national level, as these or related problems may exist  in other regional programs.

              We recommend that the Assistant Administrator, Office of Water:

              2-1    Establish national and regional  tribal drinking water program Standard
                    Operating Procedures in coordination with regional offices.  The  Standard
                    Operating Procedures should include:

                        a)  Documenting waiver determinations made by regions, and where
                           appropriate, similar determinations made by States;
                        b)  Documenting the roles,  contractual relationships, and agreements
                           between EPA, States, and tribes where the three parties share
                           responsibilities of the tribal drinking water program;
                        c)  Following records retention guidelines as required by 40 CFR 141
                           and 40 CFR 142 and guidance from the Office of Water; and
                        d)  Entering violations into SDWIS.

              2-2   Require Region 2 to submit a plan that corrects deficiencies in how it
                    currently implements its tribal drinking water  program, including those
                    identified in this report.  Once submitted, ensure that all the elements of
                    the plan are completed.

              2-3    Direct regions to issue monitoring and reporting violations, take
                    appropriate enforcement actions against tribal CWSs with health-based
                    violations or who fail to monitor or submit monitoring reports, and  enter
                    violations into SDWIS.

Agency Response  and OIG Evaluation

              The Assistant Administrator, Office of Water, responded to our draft report on
              September 4, 2008 (see Appendix C). He agreed with our recommendations and
              provided information about actions that have and will be taken to address them.
              Based on the Office of Water's comments, we made changes to the report as
              appropriate.
                                           12

In response to our first recommendation, the Office of Water states that it always
expected that EPA regions implementing the tribal drinking water program should
follow the same requirements and guidelines that EPA develops for States.
Because this expectation has never been formally documented, the Office of
Water agreed that it is appropriate to do so in formal guidance. The Office of
Water plans to issue guidance regarding these procedures in Fiscal Year 2009.
Additionally, the Office of Water states that Region 4 has already taken steps to
address issues raised in the report; it is writing a formal waiver policy, creating
records for tribal systems to document specifics of issued waivers, developing an
electronic  filing system, and coordinating with MSDH.

In response to our second recommendation, the Office of Water states that it
expects to develop a plan to help Region 2 make significant improvements to its
tribal drinking water program in Fiscal  Year 2009. It plans to implement the
improvement plan shortly after it is completed.  The recent installation of
SDWIS/STATE software on Region 2's server  will help formalize the data
management and reporting process. Additionally, Region 2 plans to make
SDWIS/STATE data available to the public through Drinking Water Watch.

In response to our third recommendation, the Office of Water agrees that it is
appropriate to document its expectations that EPA regions implementing the tribal
drinking water program should follow the same requirements and guidelines that
EPA develops for States. The Office of Water plans to issue guidance regarding
these procedures in Fiscal Year 2009.

We view these as positive actions in response to our recommendations. We
expect the Office of Water will assure its planned guidelines (Standard Operating
Procedures) address the needed corrective actions identified in our report and that
regional offices implement the guidelines.

               Details on Scope and Methodology
We conducted this review in accordance with generally accepted government auditing standards.
Those standards require that we plan and perform the review to obtain sufficient, appropriate
evidence to provide a reasonable basis for our findings and conclusions based on our objectives.
Due to the small sample size and methods used to select the tribal CWSs, the results of this
evaluation cannot be used to generalize drinking water quality at other tribal systems.

Criteria Used to Select Tribal  Community Water Systems

We reviewed the tribal portion of EPA's SDWIS for community water systems with perfect
compliance histories for the last 10 years (1997 to May 2007). Systems with perfect compliance
histories do not have monitoring and reporting or health-based violations during this timeframe.
We sorted the identified water systems by location and population, and selected final systems for
review based on these criteria. We expanded our sample of tribal CWSs by selecting other water
systems with perfect compliance histories operated and managed by tribes with the largest
populations served. The results of our independent samples were for information purposes and
did not substitute for regular drinking water sampling requirements. Our final sample of tribal
CWSs included 25 systems operated by 9 tribal nations (see Table A-l).

Interviews with EPA Region Tribal Drinking Water Staff

We interviewed tribal drinking water staff located in Regions 1, 2, 4, 5, 8, and 9 about their
oversight and assistance activities, including:
    •   The types of oversight and assistance provided to tribal CWSs,
    •   The availability of policy documents that direct regional interactions with tribes,
    •   Formal reviews of data submitted by tribal CWSs to determine if data are accurate and
       complete,
    •   The constraints to providing oversight and assistance to tribal CWSs, and
    •   Sources of non-EPA (other Federal agencies and nonprofit organizations) assistance
       available to tribal CWSs and how a region coordinates assistance efforts.

We also asked staff in Regions 1, 2, 4, 5, and 8 questions specific to the selected tribal CWSs in
each region:
    •   Contact information for the tribal leaders and water system operators,
    •   What factors contribute to the tribal CWSs' perfect compliance history over the last
       10 years, and
    •   The results of the most recent sanitary survey or visit to the tribal CWS.

Review of Tribal CWS-Related Documents and Analysis of Historic
Drinking Water Data

As part of our evaluation, we requested and reviewed a variety of documents related to the
selected tribal CWSs, such as compliance reports, sanitary survey results,  data verifications, and
operator training and certification records. We also requested historic  drinking water data for the
contaminants regulated by EPA under its National Primary Drinking Water Regulations from
each of the 25 tribal CWSs (see Table A-2).

Drinking Water Sample Collection and Analysis

We tested the drinking water quality of each of the 25 tribal CWSs for all of the  contaminants
included in the National Primary Drinking Water Regulations (except lead and copper). We
contracted with an environmental services company to collect and analyze  drinking water
samples from these systems. At most tribal CWSs (19 of 25), the team collected samples from
the point of entry and within the distribution system. At five systems we only collected samples
from the point of entry because of time needed to transport samples to the laboratory or lack of
access to sampling points in the distribution system.  At one system we did not collect any
samples because it permanently closed prior to our site visit. See Table A-3 for the tests we did
not perform at the tribal CWSs.

Collecting and analyzing the drinking water samples was done according to an approved quality
control plan.  The laboratories used to analyze the drinking water samples were certified by EPA
and the National Environmental Laboratory Accreditation Conference, Inc., and used EPA-
approved methods to analyze the samples.  We ensured that the tribal CWSs do not use the
contracted laboratories to analyze their samples routinely collected to determine their compliance
with drinking water regulations.

Interviews with Tribal  Community Water System Operators

While we  conducted our site visits to the tribal CWSs operated by nine tribal nations, we asked
each water system operator questions about the following topics:

   •   The current and future operation/maintenance challenges faced by the system in trying to
       comply with drinking water regulations,
   •   Access to sufficient funds to properly operate and maintain the water system,
   •   The relationship between the tribal CWS and the EPA region's tribal drinking water and
       tribal program staff,
   •   Reasons why the operator feels the water system has a good compliance record,
   •   Access to adequate technical assistance from EPA regions (and other sources, if
       applicable), and
   •   Any thoughts about what EPA regions could do better to assist the tribal CWS.

MEMORANDUM
SUBJECT:   EPA Assisting Tribal Water Systems but Needs to Improve Oversight, Project
             No. 2007-000873, Draft Report

FROM:      Benjamin H. Grumbles
             Assistant Administrator

TO:         Dan Engelberg
             Director of Program Evaluation
             Office of Inspector General

       Thank you for the opportunity to comment on your Office's draft report, EPA Assisting
Tribal Water Systems but Needs to Improve Oversight. I will respond briefly to the overall
findings, with more detailed responses to your recommendations and technical comments
attached.

       The report found that Tribal drinking water supplies consistently met regulatory
requirements and regional Environmental Protection Agency (EPA) staff made correct
compliance decisions. However, internal control deficiencies existed in two regions, and four
regions could improve their records management. Over the past several years, the EPA has been
working to implement programs from the Safe Drinking Water Act (SOWA) as they apply to
tribal public water systems. EPA has identified areas for improvement in regional
implementation of the SDWA through the data verification process, and the regions have
updated their procedures to address many of these issues.  Proper oversight and records
maintenance is the foundation of compliance and is necessary for achieving EPA's primary
mission of public health protection.

       EPA's goal is that all consumers receive drinking water that consistently meets public
health standards, no matter where the consumer is receiving water. The national water program
has always expected EPA Regions implementing the Tribal drinking water program to follow the
same requirements and guidelines that EPA develops for states.  This expectation, while being
implemented in most cases, has never been formally documented. The national water program
agrees with the recommendations in the draft report to clarify these procedures. We plan to issue
guidance regarding these expectations in FY 2009.

       Regions 2 and 4 have already taken specific actions to address issues raised during this
investigation.  Region 2 is in the process of addressing the incomplete reporting of Tribal
                                         22

monitoring and reporting (M/R) violations of the Safe Drinking Water Act to the federal
database.  The Region intends to report historical M/R violations that were missed and ensure
that all future violations are reported in a timely manor.  Region 4 is coordinating with the
Mississippi State Department of Health regarding record keeping practices, and accuracy and
completeness of Safe Drinking Water Information System (SDWIS) data. They are also writing
a formal waiver policy and developing an electronic filing system to improve the accuracy of the
files.  The national water program also plans to use the most recent set of regional data
verifications to improve oversight of the EPA Tribal drinking water program.

       Thank you again for the opportunity to comment on the draft report.  If you have
questions regarding our comments, please contact Nanci E. Gelb, Deputy Director, Office of
Ground Water and Drinking Water, at (202) 564-3750.

                          EPA Response to Recommendations

Recommendation 2-1:  Establish national and regional tribal drinking water program
Standard Operating Procedures in coordination with regional offices. The Standard
Operating Procedures should include:

       a)       Documenting waiver determinations made by regions, and where
               appropriate, similar determinations made by states,
       b)       Documenting the roles, contractual relationships, and agreements between
               EPA, states, and tribes where the three parties share responsibilities of the
               tribal drinking water program,
       c)       Following records retention guidelines as required by 40 CFR 141 and 40
               CFR 142 and guidance from the Office of Water, and
       d)       Entering violations into SDWIS.

Response:  The national water program has always had the expectation that the EPA Regions
implementing the Tribal drinking water program should follow the same requirements and
guidelines that EPA develops for states. However, this expectation has never been formally
documented. The national water program agrees that it is appropriate to clarify these
expectations and plans to issue guidance regarding these procedures in FY 2009.

Region 4 has already taken steps to address issues raised in the report. Specifically, record
keeping practices, communication and coordination with the Mississippi  State Department of
Health (MSDH), and accuracy and completeness of the SDWIS/State data have been improved.
Region 4 is writing a formal waiver policy and creating a record for each water system file to
document the specifics of the waiver. An electronic filing system is being developed to improve
the accuracy of the files. Region 4 has contacted the State of Mississippi to ensure that no
duplication of water systems exists in the SDWIS/Fed inventory. The State confined by email on
July 24, 2008 that the Choctaw water systems were removed from the State's inventory.

Recommendation 2-2:  Require Region 2 to submit a plan that corrects deficiencies in how
it currently implements its tribal drinking water program, including those identified in this
report. Once submitted, ensure that all the elements of the plan are completed.

Response:  The national water program agrees that Region 2 needs to make significant
improvements to its Tribal drinking water program and supports the development and
implementation of an improvement plan. We expect this plan to be developed in FY 2009 and
implemented shortly after it is completed.

Region 2 is in the process of addressing the incomplete reporting of Tribal monitoring &
reporting (M/R) violations of the Safe Drinking Water Act to the federal  database, SDWIS/FED.

The Region's plan is to report historical M/R violations that were missed and ensure that all
future violations are reported in a timely manor. This data management and reporting process is
                                         24

to be more formalized by using the SDWIS/STATE software, which was just recently installed
on the Region's network server.

Region 2 also plans to make the data in SDWIS/STATE available to the public via Drinking
Water Watch on the Region 2 web page. Drinking Water Watch is an Internet portal to
SDWIS/STATE that will allow citizens to directly access drinking water compliance data and
other information for water systems on tribal lands and encourage more public accountability
regarding water quality.

Recommendation 2-3:  Direct regions to issue monitoring and reporting violations, take
appropriate enforcement actions against tribal CWSs with health-based violations or who
fail to monitor or submit monitoring reports, and enter violations into SDWIS.

Response:  As with the first recommendation, the national water program has always had the
expectation that the EPA Regions implementing the Tribal drinking water program should follow
the same requirements and guidelines that EPA develops for states. The national water program
agrees that it is appropriate to clarify these expectations and plans to issue guidance regarding
these procedures in FY 2009.

                         Specific Comments on the Draft Report
Page 2: The Report references an IHS "Sanitary Deficiency Survey". This terminology is
incorrect.  We recommend that you revise as follows: "The Indian Health Service, through
collaboration with tribes, identifies CWS infrastructure needs and enters this data in the
Sanitation Deficiency System."

Page 3: Please add another noteworthy accomplishment: EPA is working with its Federal
partners on approaches to meeting EPA's strategic goal to reduce by half the number of homes
lacking access to safe drinking water and safe waste water disposal by 2015.

Page 6: In the first full paragraph, the second to last sentence should read "... June 2000 to
December 2003 grandfather period."

Page 10: Please revise the final sentence as follows: "Three of the six Regions we interviewed
consider information in the Indian Health Service's Sanitation Deficiency System when
prioritizing tribal drinking water system infrastructure needs and Drinking water State Revolving
Fund infrastructure grants."

Page 11: Although the OIG took samples in five regions, interviews were conducted in six
regions. All nine regions with Tribal drinking water programs offer a variety of technical and
assistance activities. The first sentence under "Conclusions and Recommendations" should more
clearly state "The six regions interviewed . . ."
