Around the Water Cooler: What’s In Your Water?
Recently a friend who knows I work on water issues asked me, “What’s in our water?” Good question, right? The answer is a little more complex than just H2O. The truth is that things we flush, throw away, or pour down the sink all have an impact on “what’s in our water.” (Continue reading. ..)

Sources of E. coli Are Not Always What They Seem
U.S. Department of Agriculture (USDA) scientists have identified sources of Escherichia colibacteria that could help restore the reputation of local livestock.

Drought and Uncertainty Nurture U.S. Water-Planning Renaissance at State Level
Official assessments of water resources and needs have a long history. A few states have had some form of water planning as far back as the Great Depression. But lately, the idea has garnered unprecedented popularity. A combination of pernicious drought, interstate conflicts, and the desire to ensure enough water for the economy and the environment has prompted an increasing number of states to take stock of their water assets and set priorities for using and protecting their rivers, lakes, and aquifers.

Over 667,000 Gallons of Wastewater Overflows into Spring Creek
The weekend rain and storms caused a wide range of damage across North Texas. In Collin County, a lightning strike on a power supply caused a water station to spill more than 650,000 gallons of raw sewage into Spring Creek — a tributary of Lake Ray Hubbard. (Continue reading. ..)

Why Water is Not the New Oil

Wimberley Water Wars
The simmering politics of water scarcity in Central Texas boiled over last Thursday night, April 25, when a Wimberley community activist group, Citizens Alliance for Responsible Development, or CARD, called a town meeting to protest the potential “massive development,” according to a CARD flier, on the newly acquired 5,000-acre Needmore Ranch on the Blanco River just east of town.

Hays Water Fight Portends Battles to Come
Dear concerned citizens, Many Wimberley area citizens have written to their legislators regarding the EP situation, asking that the legislature expands Groundwater Conservation District coverage to include the white zone east of Wimberley (the EP well area). On Wed., Rep. Isaac’s bills went before the Natural Resources Committee. The same day, many of those same citizens began getting emails from legislators indicating that they are being told Wimberley citizens are against Wimberley being included in a Groundwater Conservation District. Unbelievable, since we are already in a GCD. (Continue reading. ..)
