GRITS/STAT 5.0 Software and Documentation
The U.S. Environmental Protection Agency is no longer supporting or updating the Groundwater Information Tracking System/Statistic Software (GRITS/STAT). The software is somewhat outdated and there are a number of commercially available packages that are more up-to-date. GRITS/STAT is provided here for reference only.
