U.S. Water Use from 1950-2015 is an interactive map viewer used to visualize water use by region and date for U.S. freshwater withdrawals, 1950-present (created by USGS VIZLAB).

The U.S. Geological Survey applied the SPARROW model to assess the loads delivered in 2002 for estuaries and coastal waters along the Atlantic Ocean and eastern Gulf of Mexico.

The Alkalinity Calculator will analyze the titration curve and calculate the alkalinity or acid neutralizing capacity (ANC) of the sample using one or more of several different methods. Alkalinity is for filtered samples, while ANC is for unfiltered samples. The results will be displayed in tabular and graphical form.

The portal is a searchable, web map-based tool to facilitate public and partner access to information on over 200 subjects under USGS study in the Nation's largest State.
