WELLS OF ST. GLAIR COUNTY, ILLINOIS. 763 



At Belleville the waterworks is supplied in part from a well drilled in 

 the valley of Richland Creek and in part by impounded water from Rich- 

 land Creek and a tributary. The well entered rock at a depth of 42 feet 

 after penetrating the following series of drift beds: 



Yellow till 



Black muck, resembling soil 



Yellow clay 



Blue clay

Several prospect borings for the waterworks have been made along 

 Richland Creek Valley, between Belleville and O'Fallon, which penetrate in 

 some instances 80 feet of drift, mainly till. The amount of water is scarcely 

 sufficient to furnish a supply for water works, hence the use of impounded 

 water is continued. A well at the Star Brewery, in the northern part 

 of Belleville, reached a depth of 503 feet and obtained a slightly saline 

 water, with head 80 feet below the surface. The depth of the drift is 

 87 feet. Coal shafts near the Louisville and Nashville depot, in the north- 

 ern part of Belleville, penetrate mainly blue till and enter rock at depths of 

 40 to 80 feet, the rock surface being somewhat uneven. A coal shaft just 

 south of Belleville enters rock at 30 feet, and there are exposures of rock 

 within the city limits. 



At the village of Lebanon, in the northeast part of the county, shallow 

 wells obtain water from gravel below clay at a depth of 30 or 40 feet. 

 Considerable wood is found in some of the wells. There are also several 

 deep wells in the village obtaining water from limestone at 150 to 200 feet. 

 On a drift ridge 2 miles north of the village a well made by D. Bitzer 

 reached a depth of 86 feet without encountering rock. The lower 46 feet 

 was a hard blue till containing fragments of wood. The upper 40 feet con- 

 sisted of alternations of clay with gravel. The altitude at this well is fully 

 60 feet above the railway station at Lebanon. 



At Summerfield rock is entered at about 35 feet, but on the plain north 

 of this village the wells usually penetrate 50 feet of drift before entering 

 rock.
