These coverages describe the sampling areas of the land use studies and subunit surveys, which represent two of the three ground-water study components of the National Water-Quality Assessment program. (The third ground-water component is the flow path studies). The coverage naming convention is netcode_bnd (for example, LUSCR1_BND), or netcode_trg (for example LUSCR1_TRG.) The BND coverages represent the entire areal extent of the hydrogeologic unit defined for study. The TRG coverages represent the targeted land use within the overall area described by the BND coverage. The targeted land use coverage is supposed to nest within the overall boundary coverage, but this is not always the case. Each coverage has an ascii metadata file named "covername.met" that contains information regarding that particular coverage. The version dated 3/36/2001 is a minor update of the data set dated 4/25/2000 to make the coverage names consistent with sucodes. One coverage exists for each netcode. (See processing step for 3/26/2001.) Some are duplicates because the same boundary can describe more than one network. Purpose: The purpose of this data set is to describe the hydrogeologic units and predominant land uses that the NAWQA study units used for selecting wells for their ground water sampling networks. The boundaries will be the basis for computing nationally consistent ancillary characteristics for the ground water studies, which will be used in the analysis of water quality data. Supplemental_Information: The NAWQA study units submitted these coverages in response to the data aggregation request for boundaries of land use studies and study unit surveys issued by the National Synthesis teams in spring 1999. The guidelines are available on the Internet at . Related_Spatial_and_Tabular_Data_Sets: The generic network tables containing network codes and descriptions that are needed to explain the networks are available at .

Completeness_Report: See Lineage. Lineage: Process_Step: Process_Description: Version 1. Compiled from fall 1996 data request. Guidelines available at . Coverages were submitted from November 1996 to March 1997. These coverages were considered to be prelimary because the ground water studies still were in the planning stages. Some studies were dropped. Process_Date: 19971105 Process_Step: Process_Description: Version 2. Compiled from spring 1998 data request issued June 18, 1998. Guidelines available at . National Synthesis ground water team members reviewed the coverages as they came in and provided feedback to the study units. Questions that were not resolved by the study units before the next data aggregation in 1999 carried over into that phase. Process_Date: 19981231 Process_Step: Process_Description: Final version. Compiled from spring 1999 data request issued March 26, 1999. Guidelines available at . As part of the March 26, 1999, data aggregation effort, the National Synthesis ground water specialists again reviewed the coverages that we already had assembled and came up with another set of comments. Those comments were distributed via email to each NAWQA study unit chief, ground water specialist, and GIS specialist on April 2, 1999. The questions are listed on . The reviewers tried to ensure that the coverage metadata described details about the ground water study design, how the wells were selected, and which aquifer was being sampled. We also checked whether the network descriptions made sense and whether they matched the planning data base. We looked at maps of the wells and the ground water study boundaries to see if the wells looked randomly distributed (not clustered) and if the wells fell within the coverage boundary. A remarkable number of wells fell outside the study boundaries as delineated in the coverages. If the study boundary was not revised so that it encompassed all of the wells, we tried to make sure that the metadata explained why this situation occurred. If necessary, we renamed coverages to match the appropriate network codes and to match the type of boundary represented, a BND (overall area) or TRG (targeted land use). We checked the coverages using checkdata.aml and the metadata using the MP metadata parser. Some of the metadata files still produce errors despite our efforts to have them corrected. To accommodate the NAWQA data warehouse requirements for one data record per ground water polygon, we duplicated some of the coverages. For example, if the overall areal extent of a land use study was the same as the subunit survey boundary, we have two identical coverages, one for the overall boundary of the land use study and one for the boundary of the subunit survey. Analysts should keep this in mind when compiling ancillary data or analyzing water quality data to avoid double counting. In most cases, using the TRG coverage instead of the BND coverage probably is advisable. Although the sucodes ucollusrc1a-e are listed in the network descriptions, each sucode has only 5 wells, so National Synthesis might combine these into one (ucollusrc1). Five coverages exist for the individual lusrc1a - lusrc1e sucodes and one coverage exists for all of them together (lusrc1). !SUCODE BND COV TRG COV NOTES !almnlusmi1 lusmi1_bnd none lusmi1_bnd = sus1_bnd !almnsus1 sus1_bnd - !almnsus2 sus2_bnd - !cazbluscr1 luscr1_bnd luscr1_trg luscr1_bnd = sus1_bnd !cazbsus1 sus1_bnd - !cazbsus2 sus2_bnd - !cazbsus3 sus3_bnd - !eiwaluscr1 luscr1_bnd luscr1_trg luscr1_bnd = lusrc1_bnd = sus2_bnd !eiwalusrc1 lusrc1_bnd lusrc1_trg lusrc1_bnd = luscr1_bnd = sus2_bnd !eiwasus1 sus1_bnd - !eiwasus2 sus2_bnd - !kanalusmi1 lusmi1_bnd lusmi1_trg lusmi1_bnd = sus1_bnd !kanasus1 sus1_bnd - !kanasus2 sus2_bnd - !leriluscr1 luscr1_bnd luscr1_trg luscr1_bnd = sus1_bnd !lerilusrc1 lusrc1_bnd lusrc1_trg !lerisus1 sus1_bnd - !linjluscr1 lusrcr1_bnd luscr1_trg luscr1_bnd = sus2_bnd !linjlusfo1 lusfo1_bnd lusfo1_trg lusfo1_bnd = sus2_bnd !linjlusrc1 lusrc1_bnd lusrc1_trg lusrc1_bnd = sus2_bnd !linjlusur1 lusur1_bnd lusur1_trg lusur1_bnd = sus2_bnd !linjsus1 sus1_bnd - !linjsus2 sus2_bnd - !linjsus3 sus3_bnd - !lirbluscr1 luscr1_bnd luscr1_trg !lirbluscr2 luscr2_bnd luscr2_trg luscr2_bnd = sus1_bnd !lirbsus1 sus1_bnd - !lirbsus2 sus2_bnd - !miselusrc1 lusrc1_bnd lusrc1_trg lusrc1_trg = lusrc2_trg !miselusrc2 lusrc2_bnd lusrc2_trg lusrc2_bnd = sus2_bnd; lusrc2_trg = lusrc1_trg !misesus1 sus1_bnd - !misesus2 sus2_bnd - !misesus3 sus3_bnd - !pugtluscr1 luscr1_bnd luscr1_trg luscr1_bnd = sus1_bnd !pugtlusrs1 lusrs1_bnd lusrs1_trg lusrs1_bnd = sus1_bnd !pugtsus1 sus1_bnd - !sacrluscr1 luscr1_bnd luscr1_trg !sacrlusrc1 lusrc1_bnd lusrc1_trg lusrc1_bnd = sus1_bnd !sacrsus1 sus1_bnd - !santluscr1 luscr1_bnd luscr1_trg luscr1_bnd = sus2_bnd !santlusrc1 lusrc1_bnd lusrc1_trg lusrc1_bnd = sus2_bnd !santsus1 sus1_bnd - !santsus2 sus2_bnd - !santsus3 sus3_bnd - !sctxlusrc1 lusrc1_bnd lusrc1_trg lusrc1_bnd = sus1_bnd !sctxsus1 sus1_bnd - !sctxsus2 sus2_bnd - !sctxsus3 sus3_bnd - !sofllusag1 lusag1_bnd lusag1_trg lusag1_bnd = sus1_bnd !sofllusfo1 lusfo1_bnd lusfo1_trg lusfo1_bnd = lusor1_bnd !sofllusor1 lusor1_bnd lusor1_trg lusor1_bnd = lusfo1_bnd !sofllusot1 lusot1_bnd lusot1_trg lusot1_bnd = sus1_bnd !sofllusrc1a lusrc1a_bnd lusrc1a_trg lusrc1a_bnd = sus1_bnd !sofllusrc1b lusrc1b_bnd lusrc1b_trg lusrc1b_bnd = sus1_bnd !soflsus1 sus1_bnd - !ucollusrc1 lusrc1_bnd lusrc1_trg lusrc1_bnd = sus1_bnd !ucollusrc1a lusrc1_bnd lusrc1a_trg lusrc1_bnd = sus1_bnd !ucollusrc1b lusrc1_bnd lusrc1b_trg lusrc1_bnd = sus1_bnd !ucollusrc1c lusrc1_bnd lusrc1c_trg lusrc1_bnd = sus1_bnd !ucollusrc1d lusrc1_bnd lusrc1d_trg lusrc1_bnd = sus1_bnd !ucollusrc1e lusrc1_bnd lusrc1e_trg lusrc1_bnd = sus1_bnd !ucolsus1 sus1_bnd - !ucolsus2 sus2_bnd - !umisluscr1 luscr1_bnd luscr1_trg !umislusfo1 lusfo1_bnd lusfo1_trg !umislusot1 n/a !umislusrc1 lusrc1_bnd lusrc1_trg !umissus3 sus3_bnd - sus3_bnd = sus4_bnd !umissus4 sus4_bnd - sus4_bnd = sus3_bnd !utenluscr1 luscr1_bnd none !utensus1a sus1a_bnd - sus1a_bnd = sus1b_bnd !utensus1b sus1b_bnd - sus1b_bnd = sus1a_bnd Process_Date: 20000315 Process_Step: Process_Description: Added coverage for EIWASUS2_BND.

!COVER-ID !SUCODE SUCODE is the combination of the 4-letter abbreviation for the NAWQA study unit plus the ground-water study network code (NETCODE). Any fields besides SUCODE usually are ignored. When using the coverages, any interior polygon that has a blank SUCODE is considered to be outside of the ground-water study area. When analyzing data using the coverages, EXCLUDE the polygons that have a blank value for SUCODE.
