After more than 50 years of pulp-mill pollution, regulators have proposed restoring North Carolina's Roanoke River, including contaminated floodplain habitat damaged by toxic discharges

The Plymouth Mill began operating in 1937 as a wood and paper products manufacturing facility. Over subsequent decades, industrial operations at the site resulted in hazardous substances being released into groundwater, soil, Welch Creek and the Roanoke River (Image Credit: Domtar) For more than half a century, pollution from a pulp and paper mill has … Read more

Scientists found a surprising use for apple waste. It removed up to 100% of toxic lead from water in lab tests

Lead contamination in water is being studied through different approaches, including the use of waste materials that can help remove metal ions from water. Apple pomace, the residue left after juice production, was among the waste materials researchers examined for its ability to remove lead ions from water in laboratory experiments.Researchers compared untreated raw apple … Read more
