	Introduction

Congress has long deliberated on drinking water quality and infrastructure, which have been brought to the forefront of national attention by several events. Such events include the detection of elevated lead levels in tap water in Flint, MI, and other cities; hurricanes and other natural disasters that damaged or destroyed community drinking water infrastructure; and local source water contamination events (e.g., chemical spills and algal blooms). In March 2018, the U.S. Environmental Protection Agency (EPA) issued its sixth Drinking Water Infrastructure Needs Survey and Assessment. Communities nationwide may face financial challenges as they manage the need to repair or replace aging drinking water infrastructure. Congress deliberated on several of these drinking water infrastructure issues while developing America's Water Infrastructure Act of 2018 (AWIA; P.L. 115-270 ), enacted on October 23, 2018. Title I of the act, "The Water Resource Development Act of 2018," authorizes a wide variety of water resource and infrastructure policies, programs, and projects for the U.S. Army Corps of Engineers (USACE). Title III of AWIA primarily addresses hydropower activities of the Federal Energy Regulatory Commission. Title II and IV of the act include provisions that address EPA water infrastructure programs and other authorities. It amends SDWA to promote compliance with SDWA requirements, reauthorize appropriations for the Drinking Water State Revolving Fund (DWSRF) program, expand program eligibilities, increase emphasis on assisting disadvantaged communities, make SDWA compliance more affordable, and improve consumer confidence in public water supplies. Title II also authorizes new grant programs to reduce lead contamination in school drinking water, assist small and disadvantaged communities, and develop public water system resilience, among other purposes. Title IV addresses several other water quality and infrastructure issues by authorizing and revising activities and programs for EPA, the Bureau of Reclamation within the Department of the Interior, and other federal agencies. Title IV of AWIA extends, authorizes, and amends drinking-water-related activities and provisions administered by EPA. Specifically, these provisions authorize a water efficiency program and activities and revise the Water Infrastructure Finance Innovation Act (WIFIA) program, which provides credit assistance for water infrastructure projects. Title IV of AWIA also includes several amendments to the Clean Water Act to address stormwater by expanding a municipal sewer overflow grant programs to include stormwater management projects, reauthorizing appropriations for said municipal sewer overflow grant program, and directing EPA to establish a task force for stormwater management. For a summary of deadlines for reports, regulations, and other activities related to drinking water as provided for in AWIA, see Appendix A .

	AWIA Amendments to the Safe Drinking Water Act

Several provisions of AWIA Title II, "Drinking Water System Improvement," amend SDWA to revise existing drinking water programs, reauthorize appropriations, and establish new drinking water infrastructure grant programs. These grant programs are intended to (1) reduce lead in school drinking water, (2) support state responses to contamination or threats of contamination of drinking water supplies that may pose substantial endangerment to underserved communities, (3) assist disadvantaged communities in improving drinking water infrastructure resilience to natural hazards, and (4) improve drinking water systems serving Indian tribes in specified areas. Technical assistance, operator certification, and other programs seek to improve the technical, managerial, and financial capacity of public water systems to achieve and maintain compliance with drinking water regulations. It authorizes the use of DWSRF set-asides for source water assessment and protection activities. 107-188 ; Title IV). Eligible projects for EPA-administered assistance from WIFIA include projects that are eligible for the Clean Water State Revolving Fund (CWSRF) and the DWSRF. Conclusion

With AWIA, the 115 th Congress passed an omnibus water infrastructure and project authorization bill that affects several federal agencies. The act includes the most comprehensive amendments to the Safe Drinking Water Act since 1996, with overarching themes involving drinking water infrastructure affordability and water system compliance capacity and sustainability.
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 circumstances—including 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 infrastructure—have increased national attention to these issues. America's Water Infrastructure Act of 2018 (AWIA; P.L. 115-270), enacted on October 23, 2018, contains provisions that seek to address these and other water infrastructure concerns.
Overall, AWIA authorizes various water infrastructure projects and activities for several federal agencies. Title I of AWIA, "Water Resources Development Act of 2018," authorizes water resource development activities for the U.S. Army Corps of Engineers (USACE). Title II of AWIA constitutes the most comprehensive amendments to the Safe Drinking Water Act (SDWA) since 1996. Title III primarily includes provisions that address hydropower-related activities of the Federal Energy Regulatory Commission. Among its provisions, Title IV amends U.S. Environmental Protection Agency (EPA)-administered water infrastructure programs and several Clean Water Act authorities.
This report 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.
Title II amends SDWA to help communities achieve SDWA compliance, revise the Drinking Water State Revolving Fund (DWSRF) program, reauthorize appropriations for the DWSRF program, and increase emphasis on assisting disadvantaged communities. Provisions in Title II also revise emergency notification and planning requirements; authorize the use of DWSRF funds for the assessment and protection of drinking water sources; identify options intended to develop public water systems' technical, managerial, and financial capacity; and improve consumer confidence in public drinking water supplies. Title II authorizes a supplemental DWSRF appropriation for disaster assistance for public water systems in certain areas under certain conditions. Other provisions authorize new grant programs to reduce lead contamination in school drinking water, improve drinking water infrastructure for specified Indian tribes, respond to contamination of small and disadvantaged communities' drinking water sources, and improve the sustainability and resilience of small and disadvantaged communities' drinking water systems.
Title IV addresses several other water quality and infrastructure issues by authorizing and revising activities and programs for the EPA and other federal agencies. Title IV extends, authorizes, and amends drinking-water-related activities and programs administered by EPA. Specifically, these provisions authorize WaterSense, an EPA-initiated voluntary water efficiency labeling program, and revise the Water Instructure Finance and Innovation Act (WIFIA) financial assistance program. The WIFIA program provides credit assistance for water infrastructure projects. Other provisions authorize grant programs for innovative water technology and for water sector workforce development. Title IV also amends the Clean Water Act to expand a municipal sewer overflow grant program to include stormwater management projects, reauthorize appropriations for that program, and direct EPA to establish a task force for stormwater management.
With AWIA, the 115th Congress passed an omnibus water infrastructure and project authorization bill that affects several federal agencies. The act includes several provisions related to drinking water, with overarching themes involving drinking water infrastructure affordability and water system compliance capacity and sustainability.
