Implementing Low-Cost Modifications to Improve Nutrient Reduction at Wastewater Treatment Plants

Nutrient pollution is one of America’s costliest and most challenging environmental problems. However, many of the nation’s wastewater plants were not designed for nutrient removal and major retrofits may be a significant hurdle. EPA recently released draft report on “Case Studies on Implementing Low-Cost Modifications to Improve Nutrient Reduction at Wastewater Treatment Plants.” The recent EPA… Continue reading Implementing Low-Cost Modifications to Improve Nutrient Reduction at Wastewater Treatment Plants

Many Sampled Streams Exceed Aquatic Life Benchmarks for Pesticides

Although pesticide levels seldom exceeded human health benchmarks, pesticides continue to be a concern for aquatic life in many U.S. rivers and streams in agricultural and urban areas, according to a new U.S. Geological Survey (USGS) study published last September. The 2014 study analyzed data collected over two decades (1992–2011). More than a half billion… Continue reading Many Sampled Streams Exceed Aquatic Life Benchmarks for Pesticides
