    about if and how hydraulic fracturing activities can contaminate drinking water have been top of mind for many since the practice started getting widespread public attention about a decade ago Recognizing the validity of those concerns EPA undertook a study to see how the full hydraulic fracturing water cycle could potentially impact our drinking water resources Water Project Finance 2016 1 8 2016 The omnibus spending legislation Consolidated Appropriations Act of 2016 enacted on December 18 2015 includes a five year extension of the investment tax credit for solar and an extension for the production tax credit for wind power generation DOE Sets New Rule For Pump Efficiency 1 7 2016 This one s not on you plant operators Rather than a charge for utilities to aim higher in performance the latest regulation to impact water treatment operations as well as others falls on equipment manufacturers those who make pumps Indefensible Data The Thread That Can Quickly Unravel 12 18 2015 Not all data is good data Businesses know this or at least should and it effects how they make decisions about sales marketing and R D Cool Tool The Drinking Water Treatability Database 12 17 2015 Name a contaminant any contaminant and chances are that the U S EPA s new reference tool has you covered or at least soon will The recently revamped Drinking Water Treatability Database is set to include more than 200 contaminants with detailed information on what they are where they come from and how to get rid of them Behind The Nutrient Recycling Challenge 12 8 2015 It s pretty great when your job involves finding the cutting edge of innovation Over the past few years I ve been looking into technologies that make it easier for livestock producers to manage manure protect water
