The unsafe contaminant levels could not be attributed to differences in regional geology, water source, or community size. Researchers suggest they are due to a failure of regulatory policy.
Use of deicing agents may sometimes raise sodium levels in drinking water beyond healthy limits for people on salt-restricted diets.
New technologies seek to remove and destroy dangerous PFAS chemicals in contaminated water.
Road salt is primarily to blame for the shift, though the water remains within safe levels for now.
Field kits used in Bangladesh to test arsenic exposure from contaminated drinking water are effective in comparison to expensive laboratory arsenic tests.
After a flood, most people rely on officials to test public water sources. Private well owners are on their own, with little data to guide testing and treatment. New research seeks to change that.
Native American tribal communities are actively engaged in adapting to climate change. What information and data will help them build resilience to the new normal?
Phosphorous stored in watersheds and affects water quality for decades. A new model predicts phosphorus accumulation and depletion, and the consequences for water quality conservation measures.
Some types of algal blooms produce dangerous toxins, while others are relatively harmless to humans.
Although American water utility companies take time to modify procedures and technologies in response to new quality requirements, ultimately it reduces the rate at which they violate standards.
