About one-half of the U.S. population relies on groundwater for drinking water. The U.S. of A. of America Geological Survey is responsible for the National Water Quality Assessment Project, assessing water-quality atmospheric condition as well as whether these atmospheric condition are improving or deteriorating over time.
The results of these changing atmospheric condition are available inwards a novel USGS interactive map, A Decadal Look at Groundwater Quality. The map shows the concentrations of pesticides, nutrients, metals, as well as organic contaminants inwards groundwater as well as how these bring changed over x years.
Using the map you lot tin rank the sack guide to stance the bear witness results for a large release of organic as well as inorganic constituents. Scaled arrow markers on the map betoken whether the tested aquifers showed an increase or decrease inwards the selected share betwixt the decadal testing. For example, if you lot guide to stance the results for chlorine, the arrow markers on the map exhibit that virtually wells tested bring shown an increase inwards chlorine over the x years betwixt the 2 latest tests.
