Most people have never heard of the Rural Utilities Service (RUS), a tiny program housed within the United States Department of Agriculture (USDA). Of the $151 billion USDA budget in 2017 , only $498 million was allotted to RUS; that's about 0.3 percent. Yet RUS helps support infrastructure in small rural towns across America—and there are thousands of them right now in 2017 that have no access to drinking water that is safe. In fact, during an era when headlines about lead poisoning in Flint seem frightening yet unusual, what's actually among the most disturbing facts about the situation in Flint is that the city is far from the only community affected by a lack of access to drinkable water.

The most elegant solutions to even the most knotty problems are often those devised by nature. An interdisciplinary team of researchers from the Upper Big Sioux River Watershed Project (UBS) and South Dakota State University (SDSU) have been developing one of nature's solutions into a workable remover of contaminants such as nitrates, nitrites, phosphorus, and even heavy metals from slow-moving waters such as lakes and ponds: a small, unassuming aquatic plant called duckweed. Roger Foote, project coordinator of UBS, describes how the team decided to explore what duckweed might be capable of after his efforts to use algae to remove phosphorus from water were thwarted unexpectedly.Read More
The White River looms large in Indianapolis, with some stretches spanning more than 500 feet wide where it runs through downtown. But the river has historically received more sewage than respect. But, like many urban rivers, the White River is in the midst of a slow recovery from decades of neglect and abuse. Between a massive $2 billion sewer improvement project to new funding for programs to educate people about the river and get them on the water, the recovery could hasten as momentum builds behind the idea that a healthy, accessible White River would enrich the city and its citizens. Behind that work, a growing number of water quality monitoring programs will help track improvements on the river and catch any emerging pollution concerns.Read More
