Groundwater is presently extracted from both <br />deep and shallow aquifers. The deep Ordovicisn and Cambrian lime- <br />stones and dolomites yield 50-500 g.p.m. at depths ranging from <br />800-1,800 feet below the surface. A certain amount of water enter" <br />the deep aquifer locally and there is additional recharge from lateral <br />movement and vertical movement due to breakage in the aquiludes separat- <br />ing the shallow and deep aquifers. Gontamination of the deeD aauifers <br />is therefore a local possibility and an oCcurence which can usually <br />be prevented. Proper casing of wells is a necessary practice and <br />state law. <br /> <br />The shallow aquifers are Mississippian formations that outcrop <br />and extend to about JOO feet deep. They yield good domestic sup- <br />pltes in other than the mined areas, producing less than 50 g.p.m. <br />Solution channe]s and areas of broken chert, called breccia, can yield <br />more than 500 g.p.m.2l Surface drainage and percolation are the <br />main source of recharge for these aquifers. In many places, springs <br />flow into the streams where the strata are exposed. The streams <br />of the ares and these shallow aquifers are closely interconnected. <br />On Shoal Creek many springs contribute to streamflow while in <br />several places the surface water disappears to the shallow aquifer, <br />to reappear downstream. <br /> <br />Surface water is a major water resourCe of the area. The <br />gross amount of water in streams would serve all needs for many <br />yesrs if the supply were steady. However, rainfall in the region <br />is variable to the point of unpredictability. The water year of <br />1962 showed a total precipitation of 48 inches, while 1964 was <br />only 18 inches. Seasonal variations are also very large.22 <br /> <br />Streams leaving the Newton-Jasper County area drain about <br />2,253 square miles. Principal streams are Spring River with a <br />drainage srea of about 1,180 square miles, Shoal Creek draining <br />about 440 square miles and Center Creek 'draining about 300 <br />square miles. <br /> <br />Fresh water spring discharges support strong base flows <br />in the area streams. <br /> <br />98 <br />
