Trump’s proposed Cuts to federal regulations likely to lead to more environmental woes
Coal ash waste is poisoning fish in North Carolina lakes, scientists said this week announcing findings from a new study supported in part by the EPA. The research by scientists from Duke University showed that potentially harmful levels of selenium are building up because of emissions from coal-fired power plants.
“Across the board, we’re seeing elevated selenium levels in fish from lakes affected by coal combustion residual effluents,” said Jessica Brandt, a doctoral student in environmental health at Duke’s Nicholas School of the Environment, who led the study, published this month in the journal Environmental Science & Technology.

New website highlights the widespread problem of plastic debris
Microplastic pollution is widespread in many rivers flowing into the Great Lakes, according to U.S. Geological Survey scientists who recently took water samples from 29 Great Lakes tributaries in Minnesota, Wisconsin, Indiana, Michigan, Ohio and New York. The researchers found microplastics in all those streams, which together make up about 22 percent of the water flowing into the Great Lakes.
As if toxic waste from chemical manufacturing and other industrial processes weren’t enough, scientists say some streams are also being fouled by remnants of amphetamines — in some cases at high enough levels to alter the base of aquatic food chain.
A new study, published in the journal Environmental Science & Technology, traced the presence of illicit drugs at six stream sites around Baltimore, focusing on the Gwynns Falls watershed, which is part of the Baltimore Ecosystem Study Long-Term Ecological Research program. Two rural streams were also sampled in the Oregon Ridge watershed, the closest forested region. Continue reading “Study tracks amphetamine pollution in Baltimore streams”→
Activists plan lawsuit to win more environmental protection
Even with coral reefs around the world under the global warming gun, the U.S. Army Corps of Engineers is seeking approval for a controversial Florida dredging project that could smother parts of the only coastal barrier reef in the continental United States.
But a coalition of environmental and community groups have banded together to try and the the Corps to provide mandatory, common-sense protections for reefs near the Port Everglades dredging project near Fort Lauderdale. The project’s goal is to increase coastal access for larger ships. Continue reading “Florida harbor dredging threatens corals”→
Many streams are at risk from pharmaceutical pollution
Traces of pain-relieving substances, diabetes drugs and allergy medicines are widespread in small streams across the Southeast, especially in urban zones like Raleigh, North Carolina, the U.S. Geological Survey found in a new study.
National assessment helps pinpoint conservation issues
The health of American wetlands — at least what’s left of them — in the U.S. is a 50-50 proposition, according to the EPA, which this week released a first-ever national assessment of wetlands conditions, part of a national aquatic resource survey.
Wetlands, once maligned as no-good swamps, are critical for ecosystem health, water quality and flood attenuation, but development and agriculture have chipped away at the waterlogged areas for decades, leaving many degraded.
