Description: 2021 Oregon groundwater resource concern rating for each Public Land Survey System Township. See the "comment" column for a list of component data points that led to the concern rating in each Township. The concerns map and concern ratings treat aquifer systems as connected. However, the narrative description of individual sources of concern indicates which aquifer system is associated with each concern. Therefore, the comment for each township comprises a set of statements grouped by aquifer system. The aquifer system is indicated by a 4-letter code:
UNKN Unknown, or no aquifer system specified for the data source
QLTS Quaternary-Late Tertiary Sediment Aquifers
QLTV Quaternary-Late Tertiary Volcanic and Volcaniclastic Rock Aquifers
LTBA Late Tertiary Basalt Aquifers
METV Middle-Early Tertiary Volcanic and Volcaniclastic Rock Aquifers
TMVS Tertiary Marine Volcanic and Sedimentary Rock Aquifers
MZGR Mesozoic Granitic Rock Aquifers
MPRK Mesozoic-Paleozoic Rock Aquifers
Within the statement for each aquifer system, the comment lists all the concerning data points in that township and aquifer system. See report text for detail:
