Publication_Date: 20040816 Title: NAWQA GIS ancillary data: Surficial geology for sampling points Online_Linkage: Description: Abstract: This data set consists of surficial geology types for NAWQA sampling sites. The surficial geology data is from OFR 99-77. The sampling sites are from the NAWQA data warehouse. Purpose: This is one of the ancillary GIS data layers developed to characterize NAWQA sampling sites for national synthesis of water-quality data. Supplemental_Information: This data set excludes Alaska and Hawaii. Time_Period_of_Content: Time_Period_Information: Multiple_Dates/Times: Single_Date/Time: Calendar_Date: 1991 Single_Date/Time: Calendar_Date: 2001 Currentness_Reference: The data set is intended to represent conditions for the early 1990's to late 1990's. Status: Progress: Complete Maintenance_and_Update_Frequency: NAWQA sampling sites are added as their locations become available.
