Data Reliability Issues Impede the EPA’s Ability to Ensure Its Allotment of Infrastructure Investment and Jobs Act Funding for Lead Service Line Replacements Reflects Needs

Summary of Findings As we evaluated the execution of the EPA’s 7th Drinking Water Infrastructure Needs Survey and Assessment, or DWINSA, we saw indications that a lack of internal controls may have caused the EPA to base its fiscal year 2023 allotment of $3 billion in IIJA funds for lead service line replacements on inaccurate data. As such, there is a risk that the EPA did not allot the fiscal year 2023 IIJA funds, and will not allot future IIJA funds, according to states’ lead-service-line-replacement needs.
