Preliminary report on the ground-water resources of the Havana region in west central Illinois
- A large undeveloped ground-water reservoir underlies an area along the Illinois and Sangamon Rivers in west-central Illinois. The area is called the Havana region in this report.This report is based on data collected during the investigation and additional data on file at the Illinois State Water Survey and the Illinois State Geological Survey and in published reports. It presents geologic and hydrologic information, the geologic history of the area, present hydrologic conditions, and effects of possible future development on the ground-water resources of the region. Special emphasis is placed on the extensive unconsolidated sand and gravel deposits, which are the principal aquifers in the region, and their potential yield is evaluated. The geology and hydrology of the bedrock formations are discussed only briefly as these formations contain limited quantities of ground water, and it is of relatively poor quality. Data on water levels, pumpage, well construction features, water temperature, mineral quality of water, well-production and aquifer tests, and other hydrologic information were collected by the State Water Survey. Well logs, drilling samples, geophysical logs, and other geologic information were collected by the State Geological Survey.
