New Water Quality Portal Provides Access to over 150 Million Records

The USGS and EPA teamed up with the National Water Quality Monitoring Council (NWQMC) to launch a brand new Water Quality Portal (Portal) for water quality data. The Portal brings together chemical, physical and microbiological data from USGS’s National Water Information System (NWIS) and EPA’s Storage and Retrieval Data Warehouse (STORET).

From Decade to Decade: What’s the Status of our Groundwater Quality?

There was no change in concentrations of chloride, dissolved solids, or nitrate in groundwater for more than 50 percent of well networks sampled in a new analysis by the USGS that compared samples from 1988-2000 to samples from 2001-2010. For those networks that did have a change, seven times more networks saw increases as opposed to decreases.

Streamflow Models Evaluated for Reliability and Application to Predicting Fish Health

A new USGS study found that streamflow characteristics critical to fish in the Tennessee River basin were estimated more accurately and precisely by a statistical model than a simulated hydrograph produced by a rainfall-runoff model.

Polar Bears in Alaska Observed with Patchy Hair Loss and other Skin Lesions

ANCHORAGE — In the past two weeks, 9 polar bears in the southern Beaufort Sea region near Barrow were observed with alopecia, or loss of fur, and other skin lesions. The animals were otherwise healthy in appearance and behavior. The cause and significance of the observed lesions are unknown.

Atrazine Not Likely to Exceed Drinking Water Standard in Agricultural Groundwater

A new model predicts that atrazine, plus its breakdown product deethylatrazine, has less than a 10 percent chance of exceeding the U.S. Environmental Protection Agency’s standard for public drinking-water supplies in shallow groundwater in about 95 percent of the nation’s agricultural areas. Atrazine is a commonly used herbicide for weed control in corn and sorghum production.

USGS Identifies Streamflow Characteristics Critical to Tennessee River Basin Fishes

Streamflow characteristics critical for fish communities in the Tennessee River basin have been identified, according to recently published U.S. Geological Survey research.  Of particular note are three which describe the stability of streamflow, frequency of moderate streamflow, and the rate at which streamflow recedes after rainfall events.
