President Donald Trump proposed $1 trillion in infrastructure spending during the campaign, a pledge he repeated last month. He also promised to ensure crystal-clear, crystal-clean water. Those commitments now appear to be in doubt.

The budget blueprint Trump released Thursday appears to give infrastructure a back seat to military spending . In addition, key areas of federal spending that support the nations crumbling water infrastructure are slated to take a big hit.

Proposed cuts include various Environmental Protection Agency cleanup initiatives like the Great Lakes and Chesapeake Bay programs. Along with the Trump administrations challenges to the Clean Water Rule, and reductions for enforcement and compliance efforts, the budget may lead to higher costs for utilities to remove contaminants from water sources, eating up resources that could be going to maintaining their distribution systems.

Rural water utilities, already dealing with challenges to efforts to deliver clean water to customers, also would take a big hit from the elimination of the Department of Agricultures rural water and wastewater loan and grant programs.

Erik Olson, director of the Natural Resources Defense Council s health and environment program, spoke to these concerns at a House Environment and Public Works Committee hearing Thursday on water infrastructure.

We need a greater focus on source water protection, Olson said in his written testimony . Uncontrolled and poorly controlled source water pollution from polluters remains a serious problem.

Trumps administration signaled that water projects may be low priorities in an infrastructure push with a report saying the president would prioritize projects that involve private money. Private investors tend to prefer projects with robust revenue streams such as toll roads and bridges over less-lucrative water infrastructure projects, which generate most of their revenue through monthly water bill payments.

Our most urgent infrastructure needs are things like water systems in Flint, Michigan, Ron Klain, an Obama-era White House aide who was heavily involved with the last big federal infrastructure push, told NBC News this week. Theyre public goods we call them that because the private sector doesnt want to do them.

A leaked list of 50 top priority infrastructure projects of the National Governors Association requested by the Trump transition team included few water-related projects. Another report suggests that Trumps infrastructure package, which has gotten pushback from political leaders of both parties, could be delayed altogether until next year.

The proposed budget would slightly increase spending on EPA state revolving funds, and would maintain funding of the Water Infrastructure Finance and Innovation Act, both of which are important sources of federal support for water system repairs and improvements.
