Do Contaminants Originating from State-of-the-Art Treated Wastewater Impact the Ecological Quality of Surface Waters?
This study highlights the importance of reducing the wastewater-associated impact on surface waters. For aquatic ecosystems in urban areas this would lead to: (i) improvement of the ecological integrity, (ii) reduction of biodiversity loss, and (iii) faster achievement of objectives of legislative requirements, e.g., the European Water Framework Directive.
Water is a critical part of people’s everyday lives. In parts of the world where access to clean water is impeded, the effects have extensive implications for people and the environment. When a disaster hits, even countries with the safest water supplies can become vulnerable to a myriad of problems.
A presentation by a Moorestown utility director and an engineer included plans to replace multiple water mains throughout town and upgrade several water treatment plant systems – such as the closed Hartford Road plant and the Kings Highway plant – and address the presence of an unregulated contaminant.
People packed a village meeting in Hoosick Falls Tuesday night after receiving a notice their water might be contaminated.
Manufacturing plant Saint Gobain announced on Tuesday that water samples near its site tested positive for a chemical called PFOA.
Wisconsin residents can take a number of steps to make sure their drinking water is safe. The city of Milwaukee is considered a national leader in testing for contaminants in its drinking water. But thousands of Milwaukee children are diagnosed each year with lead poisoning, which some researchers say could be at least partially due to drinking water tainted with lead.
Being green is a point of pride-except when it describes the color of a river, lake or other waters. That green tinge means algae, which can often be harmful algal blooms (HABs) that muck up waters around the United States. Algal blooms arise from a preponderance of nutrients deposited by heavy spring and summer rains that stick around and thrive in the warmer, shallower waters of late summer and fall.
For the last 15 years, Donkey Creek has been on the Wyoming Department of Environmental Quality’s 303(d) list — one that means the water quality is poor.
In this case, there’s too much E. coli in the creek.
A National Academy of Sciences report by a team of Michigan State University researchers tested 64 river systems in Michigan’s Lower Peninsula and found that 100 percent of the rivers were contaminated by human fecal matter, and that household septic tanks were a major source.
Sludge is the nutrient-rich byproduct of water and sewage treatment that is spread on farm fields as fertilizer. It’s approved for that use, but with caveats. Experts say sludge contains heavy metals that can be toxic and traces of everything you might flush down a toilet, from pharmaceuticals to pathogens. State laws dictate that sludge must not be spread near water or during rain.
