Regional Characteristics of Ohio Groundwater

The presentation will provide a brief description of Ohio’s major aquifers followed by presentation of water quality associated with the major aquifers.  Ambient Ground Water Quality Monitoring Program water quality data, raw water samples, will be used to demonstrate water quality differences between the major aquifers using thematic map and box plots.  Several inorganic parameters, including  total dissolved solids, fluoride, strontium, exhibit strong regional characteristics associated with geologic and geochemical controls which will be discussed.  Other parameters, like manganese and arsenic, exhibit distributions that are controlled by redox controls.  These data are helpful for identifying possible water quality issues that are likely to be encountered in specific areas of Ohio.
