BMPs put to test

What are the best methods for reducing ag pollution?


Inside Science

Farmers have implemented a menagerie of agricultural pollution control methods across Chesapeake Bay's 64,000-square-mile watershed in an effort to clean up the iconic waterbody over the last three decades. But some scientists have been questioning whether some of the methods — collectively known as best management practices or BMPs — actually reduce pollution as much as estimated. An ambitious five-year, $1.5 million study aims to figure out which ones work best.


Climate change will cripple coast septic systems

Circle of Blue

Adapting sanitation systems to a fast-changing ecological reality is a challenge not only for big municipal institutions. According to new research, many septic systems — which are simple, backyard devices for addressing the ceaseless problem of toilet waste — are unfit for future climate conditions. Because of a higher water table linked to higher sea levels, conventional septic systems near the coast will not be as effective at removing harmful bacteria and nutrients.


New research finds way to make fracking safer

Science Daily

Injecting wastewater deep underground as a byproduct of oil and gas extraction techniques that include fracking causes human-made earthquakes, new research has found. The study, which also showed that the risk can be mitigated, has the potential to transform oil and gas industry practices.
