1. Short title This Act may be cited as the Healthy Drinking Water Affordability Act or the Healthy H2O Act . 2. Findings Congress finds that— (1) clean and safe drinking water is necessary to ensure public health and a vibrant economy; (2) communities that are dependent on private groundwater supplies to meet domestic drinking water needs, as well as those that continue to experience drinking water infrastructure challenges from public water supplies, including with infrastructure into and within households and living facilities, are disproportionately impacted by drinking water quality issues; (3) in many instances, those communities and their households have been adversely impacted by the presence of 1 or more naturally occurring and human-caused contaminants found in drinking water, such as lead, arsenic, nitrate, nitrite, and volatile organic compounds, as well as federally unregulated contaminants, including perfluoroalkyl and polyfluoroalkyl substances and hexavalent chromium (chrome-6), in local groundwater or other drinking water supplies; (4) public health organizations and institutions, such as the Centers for Disease Control and Prevention, have cited giardia, enterovirus, radon, rotovirus, norovirus, shigella, campylobacter, salmonella, hepatitis A, cryptosporidium, and e. coli as among the major diseases and contaminants that can be present in drinking water sources; (5) investments in projects to improve and support drinking water infrastructure are critically important to addressing water quality in the United States, but because those projects can typically take many years to complete, the current, and in some cases the ongoing, needs of communities impacted with immediate drinking water quality challenges cannot be or are not addressed in a timely manner
