Additional Regional Groundwater Quality Data for the Karst-Carbonate Aquifers of Northeast Iowa, April 15, 1983

摘要

Since completion of the phase-one regional karst groundwater quality assessment (Hallberg and Hoyer, 1982) other data on groundwater quality from the carbonate aquifer areas have become available. These data provide further useful background information on the karst groundwater problems. These additional data were not directly part of the second phase (Big Spring Study) ofudthis project, and thus are presented here in a separate report. This report is essentially a supplement to the phase-one report (Hallberg and Hoyer, 1982), and the data presented here will be merged with the first report forudlater publication.
