Welcome to the home page of the Soil and Water Geospatial Analysis Lab

The Soil and Water Geospatial Analysis Lab (SAWGAL) was founded by Dr. Brian Needelman in 2002 to study spatial and geostatistical analyses, soil mapping and applications, pollutant fate and transport, and apply pedological concepts to environmental problems.

SAWGAL is in the Department of Environmental Science and Technology in the College of Agriculture and Natural Resources. The lab is located in the HJ Patterson Building on the University of Maryland College Park campus and has field, laboratory and greenhouse sites elsewhere on campus and through the region, especially on Maryland's Eastern Shore.
