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).

Alkalinity Calculator

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.
