By the side of a washboard-rough dirt road, in a garage piled high with rocks neatly stored in pizza-sized boxes, the long-awaited study has begun to determine how much of the world’s largest chromium-6 plume is the result of a San Francisco-based utility’s operations and how much was put there by nature.
In March 2014, two United States agencies charged with stemming pollution in the nation’s waters proposed a 2-page rule change in federal clean water regulations, a change based on more than 1,000 scientific studies, that was meant to clear up years of legal muddiness in defining which small streams and wetlands fell under government regulation.
Miles from the nearest paved road in the San Bernardino National Forest, two sounds fill a rocky canyon: a babbling stream and the hissing of water flowing through a stainless steel pipe.

Nearly 600 Maricopa County school children collaborated this past year to create their own water filter to clean the “polluted” water made in a model city. They were participating in an Arizona Science Center project called Planet Water, thanks in part to a grant from Central Arizona Project.
On Tuesday, California senators Dianne Feinstein and Barbara Boxer launched a third effort by introducing legislation in the Senate. U.S. Rep. John Garamendi, D-Walnut Grove, also introduced a bill in the House.

Snowpack—which essentially serves as a water tower for the western United States—produces vital meltwater that flows off the mountains each spring. … But the snowpack is becoming more like a snow gap, as temperatures in the Cascades and Sierra Nevada become too warm for the snow that replenishes the ecosystem each winter.
Surveys by the Department of Water Resources showed the snowpack across the entire mountain range at 19 percent of average for early March, a level deemed “alarmingly low” by officials. … On March 17, the State Water Board will consider extending emergency drought regulations and adding more stringent conservation measures.
