Groundwater Resources of Northeastern Ohio

Complete the questions below by typing the answers in the boxes and printing the finished form or print the form and write the answers in by hand.  

Many Midwestern states are mantled with glacial deposits left behind as ice sheets retreated north at the close of the last ice age. Aquifers have been developed in coarse grained sediments of the glacial deposits and in some of the underlying bedrock units. This exercise seeks to characterize the geology of groundwater resources in a glaciated county in northeastern Ohio.

Use information provide in the factsheets on Summit County water resources and Summit County groundwater resources at the Ohio State University Extension Service's website to answer the questions below. 

  1. The best aquifers in Summit County yield 500-1,000 gpm. Are these aquifers composed of bedrock or unconsolidated glacial deposits?

bedrock                 unconsolidated deposits

  1. Exactly what are the deposits in these aquifers?

  1. What does the abbreviaton gpm represent?

  1. Which area of Summit county produces the least groundwater?

north                south                east                 west

  1. What are the geological characteristics of the areas that produce the least groundwater?

  1. Are the aquifers of Summit county open (unconfined) or closed (confined)?

open                closed
Examine the map of Summit County groundwater resources.  Akron is located over deposits labelled "C" on the map (Sharon conglomerate and Pottsville Formations).  Wells in these units have consistent yields of  up to 50 gpm and occassional intermittent yields of up to 250 gpm.
  1. Which city is located above the better groundwater source?

Akron                Barberton                     Peninsula
Review information on the groundwater resources of Washington County in southeastern Ohio. Washington County is not covered with glacial deposits like Summit County. A map showing the surficial geology (glacial deposits) of Ohio is available at the Ohio Geological Survey's website.
  1. How do the groundwater resources of glaciated Summit County compare with those of unglaciated Washington County in southeastern Ohio?
