Congress has long deliberated on the condition of drinking water
infrastructure and drinking water quality as well as the financial
and technical challenges some public water systems face in ensuring
the delivery of safe and adequate water supplies. Several events
and circumstancesaincluding source water contamination incidents;
water infrastructure damage from natural disasters, such as
hurricanes; detection of elevated lead levels in tap water in
various cities and schools; and the nationwide need to repair or
replace aging drinking water infrastructureahave increased national
attention to these issues. America's Water Infrastructure Act of
2018. Chapter 1 focuses on the drinking water provisions of Title
II and Title IV of AWIA, which authorize appropriations for several
drinking water and wastewater infrastructure programs for projects
that promote compliance, address aging drinking water
infrastructure and lead in school drinking water, and increase
drinking water infrastructure resilience to natural hazards.
Chapter 2 summarizes the Safe Drinking Water Act (SDWA) and its
major programs and regulatory requirements. The quality of water
delivered by public water systems has been regulated at the federal
level since enactment of the 1974 Safe Drinking Water Act (SDWA).
Since then, the U.S. Environmental Protection Agency (EPA) has
issued regulations for more than 90 contaminants, and all states
(except Wyoming) have assumed primary responsibility for
administering the federal drinking water program and overseeing
public water system compliance. Congress last broadly amended the
law in 1996. Among the key provisions, the 1996 amendments
authorized a Drinking Water State Revolving Fund (DWSRF) program to
help public water systems finance improvements needed to comply
with federal drinking water regulations and to address the most
serious risks to human health as reported in chapter 3. Drinking
water contaminated with lead in Flint, Michigan, renewed awareness
of the danger lead poses to the nation's drinking water supply.
Lead exposure through drinking water is caused primarily by the
corrosion of plumbing materials, such as pipes, that carry water
from a water system to pipes in homes. EPA set national standards
to reduce lead in drinking water with the Lead and Copper Rule
(LCR). Chapters 4-7 review the issue of elevated lead in drinking
water. According to DOD, about 3 million people in the United
States receive drinking water from DOD public water systems, which
are to comply with EPA and state health-based regulations. EPA and
DOD have detected elevated levels of two unregulated,
DOD-identified emerging contaminants found in firefighting
foamaPFOS and PFOAain drinking water at or near installations.
Perchlorate, an unregulated chemical used by DOD in rocket fuel,
can also be found in drinking water. Chapters 8-11 review DOD
management of these drinking water contaminants.
