and BONUS ROUND: the various Party platforms on water-project infrastructure, lead contamination and water regulation (emphasis mine):
Democratic Party (The 2016 Democratic Party Platform)
We will dramatically increase federal infrastructure funding for our cities—making significant new investments in roads and bridges, public transit, drinking and wastewater systems, broadband, schools, and more.
and
Democrats are committed to closing the Halliburton loophole that stripped the Environmental Protection Agency (EPA) of its ability to regulate hydraulic fracturing, and ensuring tough safeguards are in place, including Safe Drinking Water Act provisions, to protect local water supplies.
and
Democrats believe clean air and clean water are basic rights of all Americans. Yet as we saw in Flint, Michigan, low-income communities and communities of color are disproportionately home to environmental justice “hot spots,” where air pollution, water pollution, and toxic hazards like lead increase health and economic hardship Democrats believe we must make it a national priority to eradicate lead poisoning, which disproportionately impacts low-income children and children of color and can lead to lifelong health and educational challenges. We will prioritize hiring and training workers from affected communities to clean up toxic brownfields and expand clean energy, energy efficiency, and resilient infrastructure.
Republican Party (the 2016 Republican Party Platform)
Like the rest of the economy, agriculture has suffered through eight years of the Democrats’ regulatory juggernaut, particularly from the Environmental Protection Agency (EPA). States, not Washington bureaucrats, are best equipped to engage farmers and ranchers to develop sound farm oversight policies. The EPA’s Waters of the United States (WOTUS) rule, issued jointly with the Army Corps of Engineers, is a travesty. It extends the government’s jurisdiction over navigable waters into the micro-management of puddles and ditches on farms, ranches, and other privately-held property. Ditches, dry creek beds, stock ponds, prairie potholes, and other nonnavigable wet areas are already regulated by the states. WOTUS is now subject to judicial review and must be invalidated, but that will not be sufficient.
and
Unelected bureaucrats must be stopped from furthering the Democratic Party’s political agenda through regulatory demands forced upon citizens and businesses beyond that which is required by law. We must never allow federal agencies to seize control of state waters, watersheds, or groundwater. State waters, watersheds, and groundwater must be the purview of the sovereign states
and
The central fact of any sensible environmental policy is that, year by year, the environment is improving.Our air and waterways are much healthier than they were a few decades ago.
and
"We will enforce the original intent of the Clean Water Act, not it’s distortion by EPA regulations. "
Green Party (Green Party Platform)
Set health and sustainability water quality guidelines for drinking water supported by the peer-reviewed scientific literature. Regulations are needed or need improvement, for example, for arsenic, bacteria, viruses, protozoa, fluoridation chemical species such as fluoride and fluorosilicate, water disinfection-by-products, environmental estrogens, and pharmaceuticals (medicines).
and
"Greens oppose the privatization of water and demand that the U.S. government pass strong laws with effective enforcement mechanisms to assure a safe and adequate supply of water for its citizens and all life within its borders."
Libertarian Party (LP Platform)
"Competitive free markets and property rights stimulate the technological innovations and behavioral changes required to protect our environment and ecosystems. Private landowners and conservation groups have a vested interest in maintaining natural resources. Governments are unaccountable for damage done to our environment and have a terrible track record when it comes to environmental protection. Protecting the environment requires a clear definition and enforcement of individual rights and responsibilities regarding resources like land, water, air, and wildlife. Where damages can be proven and quantified in a court of law, restitution to the injured parties must be required."
