The following walk-through exercise provides a sample project for you to explore using the USGS online database for groundwater use in the United States. The United States Geological Survey (USGS) is a scientific agency of the US government. USGS scientists study the landscape, natural resources, and natural hazards within the United States. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS collects several types of hydrological data sets and they are readily available on their website.
USGS web search activity:

USGS Water-Quality Data for the Nation web page walk-through:




Assignment: Locate three agriculture and three oil wells in either site A or site B. In site A, choose wells that have a count of greater than five (the more the better!) and in site B, try to find wells that have a count greater than two. (Some have counts greater than 10; can you find them?)
Using the data you have collected and the website, answer the following questions:

  1. Were there any overall trends in groundwater levels over time? If so, why?

  1. Were there differences in groundwater levels over time in one area versus another?

  1. Give a prediction on the future availability of groundwater resources using this data.

  1. Locate a well in your area and report interesting information you find about the groundwater there.
