Title Potential GWI Sources--Microscopic Particulate Analysis
Date
Published
August 2003
Description A 16 page guidance document for drinking water systems outlining the Microscopic Particulate Analysis (MPA) method of analyzing groundwater sources that may be "under the direct influence of surface water" (GWI). This approach is intended to identify organisms that occur only in surface waters and whose presence in groundwater clearly indicates that at least some surface water has been mixed with it.
