<edomvd>Primary composition of glacial deposits is sand and gravel with a confining layer</edomvd>
<edomvds>Limited to portions of the Great Miami River Valley where the probability of encountering a confining or semi-confining zone within the aquifer is high. Such a confining layer would split the sand and gravel into upper and lower aquifers. The thickness and continuity of the confining layer may vary considerably in the mapped area.</edomvds>
</edom>
<edom>
<edomv>Tsg</edomv>
<edomvd>Primary composition of glacial deposits is Till with sand and gravel</edomvd>
<edomvds>Predominantly till, contains sand and gravel lenses of varying thicknesses. These lenses may or may not be interconnected. Wells are developed in these lenses.</edomvds>
</edom>
<edom>
<edomv>T</edomv>
<edomvd>Primary composition of glacial deposits is Till</edomvd>
<edomvds>Predominantly till, water well logs typically lack indication of sand and gravel lenses. Wells are typically finished in the underlying bedrock. Wells commonly are developed at or near the drift/bedrock contact. Shallow dug wells may still be used on a limited basis. Shallow monitor wells may be completed in this unit. Many of these mapped areas are shallow to bedrock; mapping may include small areas where bedrock comes to ground surface.</edomvds>
</edom>
<edom>
<edomv>SGt</edomv>
<edomvd>Primary composition of glacial deposits is sand and gravel with till</edomvd>
<edomvds>Predominantly sand and gravel with thin covering of till or thin interbedded layers of till. Commonly associated with ice-contact features, i.e. kames, eskers, some moraines, etc. It is also associated where thin beach ridges directly overly till.</edomvds>

<edom>
<edomv>SGf</edomv>
<edomvd>Primary composition of glacial deposits is snad and gravel with fines</edomvd>

This area is characterized by steep, highly stream-dissected uplands. The Cuyahoga River, Chagrin River and Rocky River drain this area. Clayey till commonly forms a thin cover over the highly eroded shale bedrock. Yields are generally less than 5gpm. In a few areas where drift is in the 25-100' range, wells completed in thin sand lenses may yield 5-25gpm.</edomvd>
</edom>
<edom>
<edomv>Broadway</edomv>
<edomvd>Broadway - Area in northern Union and Delaware Counties which roughly corresponds to the Broadway End Moraine.

<edomv>Chillicothe</edomv>
<edomvd>Chillicothe - Upland area in central Ross County which is highly dissected by Paint Ck and it's tributaries. The area is characterized by steep bedrock uplands. The till is typically thin, less than 25'. Yields are typically less than 5 gpm if wells can be developed at all. Drift in some of the less steep valleys is in the 25-100' thickness range.

<edom>
<edomv>Chippewa</edomv>
<edomvd>Chippewa - A large tributary of the Tuscarawas River which drains southern Medina County and northern Wayne County. The local is primarily part of a large buried valley system. Drift thickness is commonly greater than 100' with some tributaries in the 25-100' thickness range. In tributary valleys, wells are completed in sand and gravel lenses interbedded in finer alluvium or underlying till. Yields for these wells are in the 5-25 gpm or 25-100'gpm range. In the large trunk valleys, thick sequences of sand and gravel outwash provide yields of 100-500 gpm to greater than 500gpm for large diameter, properly-constructed wells. Test drilling may be necessary to determine the best-yielding deposits.</edomvd>
</edom>
<edom>

</edom>
<edom>
<edomv>Cuba</edomv>
<edomvd>Cuba - An area roughly corresponding to the Cuba End Moraine which extends across Greene, Clinton, and Highland Counties. The moraine typically has over 100' of drift or is in the upper part of the 25-100' range. The moraine contains appreciably thicker drift than the surrounding ground moraine and thin upland areas. Wells are completed in thin sand and gravel lenses interbedded with thick sequences of silty till. Yields are usually in the 5-25 gpm range.</edomvd>
</edom>
<edom>
<edomv>Cuyahoga</edomv>
<edomvd>Cuyahoga - An extremely variable local which occupies much of northeastern Ohio. The local includes both current and ancestral channels and tributaries of the Cuyahoga and Little Cuyahoga Rivers. Included are areas of alluvial, buried valley, and thick drift complexes. Smaller tributaries are typically alluvial settings containing less than 25' of drift to 25-100' of drift. Yields in these areas vary from less than 5 gpm to 5-25gpm depending upon the availability of sand and gravel lenses within the finer alluvium. The composition of the thick drift in the buried valley and thick drift complex settings is highly variable. In central Geauga and western Portage Counties, the buried valley deposits contain thick sequences of sand and gravel outwash. Yields for larger diameter wells range from 100-500 gpm to greater than 500gpm. In northern Summit County and southern Cuyahoga County, the present and ancestral channels of the Cuyahoga are filled with thick sequences of very fine-grained till, lacustrine, and colluvium. Yields are commonly less than 5gpm or in the lower 5-25gpm range. Near the mouth of the Cuyahoga River in Cleveland, the deposits begin to coarsen. Fine-grained sands near the surface yield 5-25 gpm to 25-100gpm. Thicker sand and gravel may be encountered at greater depths. Test drilling is needed to locate the best of these deposits, which may yield up to 100-500 gpm. The Division of Water and the USGS have abundant information on these aquifers, especially in Portage County.</edomvd>
</edom>
<edom>
<edomv>Deer Ck</edomv>
<edomvd>Deer Ck - A tributary of the Scioto River which drains parts of Madison, Pickaway, and Ross Counties. The main trunk part of the stream overlies a buried valley containing over 100' of drift in most segments. In the northern end of the valley, wells are developed in sand and gravel lenses interbedded in finer alluvium or the underlying till. Yields are 5-25 gpm to 25-100gpm. Further south, closer to the confluence of the Scioto River, layers of sand and gravel outwash become thicker and more laterally extensive and yields increase to 25-100 gpm and 100-500 gpm. Tributaries and the headwaters of Deer Ck are alluvial settings containing 25-100' of drift. Yields of 5-25 gpm are obtained from thin sand and gravel lenses interbedded with finer alluvium or underlying till.</edomvd>
</edom>
