This month marks the 40th anniversary of the Clean Water Act (CWA), the primary federal law regulating discharges of pollutants into U.S. waters. As far as the developed world’s water priorities go, a great deal has changed since 1972. For one thing, the top challenge back then was eliminating releases of toxic substances. Today, that challenge is arguably being met, and we are now getting more...

Production of natural gas from shale formations presents key water management challenges. As the number of gas drilling operations continues to grow in shale plays around the world, and the practice of hydraulic fracturing (frac or fracing) of gas wells remains widespread, efficient water use strategies are becoming critical aspects of shale gas operations. Fresh water supplies for drilling and fracturing...

For years it has been the common practice to treat process water with various chemistries to prevent scale, corrosion and microbiologicals. However, as regulatory issues tighten, water scarcity becomes a growing concern and the cost of treatment chemicals increases, chemical processors are finding that stringent treatment chemicals are not the only answer. Instead, they’re relying upon a multi-prong...
