LASTUPDATE Date which fields were updated
*REASON Why groundwater source was not located or does not have
associated attributes:
PURCH - Using puchased water from other source location
CNC - Could not contact while gathering data
DCE - Data corruption error during post-processing GPS data
INACT - Inactive source and/or system
MINE - System located on mine
NCDTF - Not completed due to funding (mainly Campbell County)
NEW - Source new or being developed (created in 1996 only)
NLD - Source not listed in database individually
WNC - Contact would not cooperate with the use of GPS
DUPL - Duplicate within database
*POINT_CODE Code differentiating between source type and who located it (for
mapping and QA/QC purposes):
EPA_GW - Groundwater source located by USEPA
EPA_PGW - Purchased groundwater source located by USEPA
EPA_SW - Surface water source located by USEPA
EPA_PSW - Purchased surface water source located by USEPA
WWRC_GW - Groundwater source located by WWRC
* indicates new field created by WWRC specific for project and not found within USEPA's system and source tables.
