The Moraine Unit consists of deposits associated with the Defiance Moraine ( Inner Ridge) . This unit is located along the western edge of metropolitan Detroit where rapid development is occurring.
State. Excluding the Detroit Metropolitan area, about 90 percent of the rural and 70 percent of the total population of the State are supplied with water from underground sources (MacKichan, 1957). Despite the abundance of the ground water in Michigan, many problems face those concerned with the development and management
in southeastern Michigan is complicated because of the complex nature of sedimentation by both ice and water [34]. Groundwater flows toward the surface water within the sand units, and if present, is generally found at a depth ranging from ~one to three meters from the land surface [6,31]. However, in Metro Detroit, the perched or discontinuous
and inland lakes, and ground water. During 1950 Lake St. Clair and the De troit River provided 2,896 million gallons per day (mgd), or 98.3 percent of the total usage of 2,949 mgd. Tributary streams and inland lakes supplied about 10 mgd, or 0.3 percent, and ground water contributed43 mgd, or 1.4 percent of the total.
The water used for all purposes in the Detroit area is obtained from three sources: Lake St. Clair and the Detroit River, their tributary streams and inland lakes, and ground water. During 1950 Lake St. Clair and the Detroit River provided 2,896 million gallons per day (mgd), or 98.3 percent of the total usage of 2,949 mgd. Tributary streams and inland lakes supplied about 10 mgd, or 0.3 ...
Contaminant risk factors in surface soil were evaluated within the urbanized Rouge River watershed in southeastern Michigan, USA, which includes metropolitan Detroit. An analytical risk factor model and Geographic Information Systems overlays were used to quantify and characterize the potential impacts of five categories of contaminants including DNAPLs (dense nonaqueous phase liquids), LNAPLs ...
Michigan, 45% of its citizens are served by groundwater as their primary drinking water source. Total groundwater withdrawals from all sectors in Michigan alone averaged 541 MGD (EGLE 2019). Currently, the largest usage of groundwater in Michigan is for public water supply (208.9 MGD),

The great importance of the fresh ground-water resources of Michigan is evident because 90 percent of the rural and about 70 percent of the total population of the State exclusive of the Detroit metropolitan area are supplied from underground sources. The water-supply and public-health problems that have been caused by some cases of ground-water contamination in the State illustrate the necessity
