Federal Water Tap, July 22: A Local-Federal Fire Partnership

The consequences of severe fires last long after the flames have been snuffed out. Watersheds and reservoirs, in particular, are at risk from debris, erosion, and pipe-clogging ash, all of which degrade water quality and increase the cost of treatment. So the Interior Department and the Department of Agriculture announced a plan to work with […]

Federal Water Tap, July 15: Colorado River Basin Sniffs a Shortage

Because the outlook for Colorado River reservoirs gets gloomier every month, I might soon have to drop the question mark from this subheading. Why? The July 24-month study from the Bureau of Reclamation forecasts that a first-ever water shortage on the iconic river could be declared as soon as April 2015. A shortage is triggered […]

During the drought that year water reserves in Texas dropped by 62.3 billion cubic meters (50.5 million acre feet) — […]

Federal Water Tap, July 8: How to Make Strategic Cuts to Groundwater Monitoring Networks

Eliminate the Redundant A U.S. Geological Survey hydrologist developed a model to help water managers decide which groundwater monitoring wells to cut in order to maintain quality data while reducing costs. Jason Fisher tested his model, which is based on how chromosomes interact, on two groundwater monitoring networks in Idaho. The tool works in the […]

Federal Water Tap, July 1: President Obama’s Climate Change Plan

Regulate, Innovate, and Adapt That is the crux of President Barack Obama’s climate change plan, unveiled in a speech last Tuesday at Georgetown University and in an accompanying 21-page document. The president proposed actions, with the exception of his budgetary aspirations, that need no endorsement from Congress. In a move sure to face legal challenges, […]

This Seattle Office Building Has Composting Toilets…

And solar panels. And rainwater tanks. Plus geothermal heating and sustainable timber. But is it the right model for the next generation of urban infrastructure?
