At a Glance
Why We Did This Project
The Office of Inspector
General (OIG) for the
U.S. Environmental Protection
Agency (EPA) examined
whether the EPA adequately
ensures that public drinking
water systems notify their
consumers as required by
public notice regulations
authorized under the Safe
Drinking Water Act, such as
when the drinking water poses
a risk to public health (e.g.,
when there are unsafe levels of
contamination).
The EPA approved most
states, territories and the
Navajo Nation to operate their
own drinking water programs.
This is known as primacy. EPA
regions directly implement
drinking water programs in the
remainder of Indian country,
the District of Columbia and
Wyoming; in this report we call
this primacy, as well. The EPA
oversees the primacy agencies.
This report addresses the
following:
•	Ensuring clean and safe
water.
•	Compliance with the law.

EPA Must Improve Oversight of Notice to the Public on
Drinking Water Risks to Better Protect Human Health
Without reliable
information about
drinking water,
consumers cannot
make informed health
decisions and the EPA
cannot provide
effective oversight.
What We Found
Primacy agencies have the responsibility to oversee
whether public water systems meet federal
requirements, including notifying consumers of certain
situations regarding their drinking water. We found
that some primacy agencies do not consistently fulfill
their responsibility to enforce drinking water public
notice requirements. Specifically, some primacy
agencies do not consistently record violations, nor do
they track the need for and issuance of public notices.
In addition, the EPA's protocol for assessing primacy agency oversight does not
fully cover all public notice requirements. As a result, not all primacy agencies
know whether public water systems under their supervision appropriately notify
consumers about drinking water problems, and the EPA and primacy agencies
do not hold all public water systems to the same compliance standards.
The EPA does not have complete and nationally consistent information about
public water systems' compliance with public notice requirements because
primacy agencies do not use consistent methods to identify problems with public
notice or record violations in the national drinking water database. As a result, the
EPA cannot fully monitor compliance and oversee the implementation of this
important part of the drinking water program.
Additionally, the EPA's public notice guidance documents to primacy agencies
and public water systems are inconsistent with regulations and out of date.
Consequently, primacy agencies lack accurate guidance on their oversight
responsibilities. Public water systems also lack guidance about current, relevant
tools to provide effective public notices and may miss opportunities to efficiently
inform consumers about drinking water problems.
Recommendations and Planned Agency Corrective Actions
We made nine recommendations, including that the EPA require primacy
agencies to comply with oversight requirements related to public notice and
to follow data reporting requirements. We also recommended that the agency
update public notice guidance, define the acceptable methods and conditions
under which notices can be delivered electronically, and improve public notice
violation information in the national drinking water database. The EPA provided
acceptable corrective actions and estimated completion dates for six
recommendations. Three recommendations are unresolved, with resolution
efforts in progress, because the action official for these recommendations, the
Deputy Administrator, did not respond to our draft report.
