In a U.S. Geological Survey-led study, researchers combined more than a decade of data on dragonfly mercury concentrations with commonly measured water-quality and landscape characteristics to develop a model that estimates freshwater mercury risk on protected lands across the nation.
A major advantage of the new model is its ability to estimate mercury levels in previously untested areas. The model also provides important insights into how mercury exposure risk varies across different landscapes using commonly collected and widely available information about water chemistry and land cover.
Results from the new model will assist scientists, resource managers and policymakers in evaluating environmental health risks and monitoring trends over time. Read more about the study here.
Richmond WTP Operators Worked for 21 Days Straight Amid Crisis
Following a major failure at Richmond, Virginia's water treatment plant, its team of operators has stepped up in a big way to keep essential services running, as city officials maintained around-the-clock staffing, with some employees working up to 21 consecutive days.
The Department of Public Utilities has relied on wastewater staff, external experts, and regulatory personnel to stabilize operations, and had plans to transition back to normal scheduling as soon as possible.
Trump Orders Federal Agencies to Override California Water Policies
The Hill reports that President Donald Trump recently issued an executive order directing federal agencies to override California’s water policies to ensure adequate resources for wildfire prevention and response.
Citing dry hydrants and empty reservoirs as failures, the order mandates immediate action to maximize water deliveries, following Trump’s criticism of the state’s handling of wildfires.
