Siegel, D.I. Geochemistry of the Cambrian-Ordovician aquifer system in the northern Midwest, United States. United States: N. p.,   The Cambrian-Ordovician aquifer system ranks ninth in the nation as a source of groundwater for public supply, providing million gallons per day for this use. The aquifer underlies an area with a population of about 26 million people in parts of seven states and includes the metropolitan areas of Chicago, Illinois; Milwaukee, Wisconsin; and Minneapolis-St. Paul, Minnesota. This report provides a regional assessment of groundwater quality of the Cambrian-Ordovician aquifer system, based primarily on raw water samples collected by the NAWQA Program during through The NAWQA Program has published findings in local study-unit reports encompassing parts of the Cambrian-Ordovician aquifer system.   Geochemistry of the Cambrian=Ordovician Aquifer System in the Northern Midwest, United States.

A six-State area in the northern Midwest of the United States has become increasingly dependent on ground water from the Cambrian-Ordovician aquifer system, which consists of a sequence of sandstones, carbonate rocks, and shales. Ground-water withdrawals from the aquifer system began in the late 's and increased to approximately million gallons per day (1, cubic feet per .

Boundary Condition at a Well [11] The boundary condition at an active (injection/pumping) well and a passive (leaky) well is treated in a similar way. For an active well screened at well‐aquifer segments the flow rate, Q(t), is known, either constant or Cited by: 8.
