Pollution in Surface Water and Groundwater
Effects of Human Activities on the Interaction of Groundwater and Surface Water, USGS
Reviews the effects agricultural development, urban and industrial development, drainage of the land surface, modifications to river valleys, and modifications to the atmosphere have on groundwater and surface water, including pollution and disturbance of flow paths. Site includes several color images. Includes links to case studies on the effects of irrigation, nitrate contamination, pesticide application, the increase of water levels in surface reservoirs, vegetation removal, and acid rain on water reservoirs.
Arsenic in Groundwater Resources of the United States, USGS
Discusses arsenic concentrations in potable water across the U.S. Includes a map that shows arsenic concentrations in groundwater of the United States.
Ground Water Studies, USGS
Contains a review of the threats to our nation's water supply and the steps the USGS is taking to minimize the effects of natural hazards and environmental damage caused by human activities on groundwater supplies.
National Field Manual for the Collection of Water Quality Data, USGS
Contains links that describe the basic techniques of water resource investigations, including water sampling. Click on links to open table of contents for a chapter on the particular technique. One chapter is devoted to preparations for water sampling, including tips on materials to take into the field, tips on field trip responsibilities, and advice on how to select sampling sites. There is also a chapter that reviews the techniques involved in the actual process of collecting water samples.
Drinking Water Contaminants, EPA
Provides a table that outlines the EPA's standards for safe drinking water, defining levels of contaminants and listing possible sources of these contaminants.
