The report summarizes information about your facility, and samples collected and analyzed from your well(s). The well site survey provides an inventory of the area around your well(s) to help increase your awareness of potential hazards to groundwater utilized by your facility. This information and technical data will assist you in developing and implementing local groundwater protection measures authorized by the Act. FACILITY DESCRIPTION AND GEOLOGIC PROFILE OF WELL SITES The Village of Ransom has four public water supply wells. The facility produces 77,000 gallons per day on average to an estimated population of 450. Wells Nos. 3 and 4 are the sole source of potable water. Well No. 2 is used only in case of fire and Well No. 1 has not been used in many years. See Table I for a description of each well. Wells Nos. 1 and 3 utilize a shallow bedrock aquifer and wells No. 2 and 4 utilize a deep bedrock aquifer. These aquifers are overlain by at least 50 feet of relatively impermeable till. Permeability is a measure of the ability of a soil or sediment to transmit fluids. A detailed description and geologic profile is found in the Facility Wells Report (Appendix C). TABLE I Mi n. Max.

The well samples were analyzed for volatile organic and aromatic chemicals (VOC/VOA) and inorganic chemicals (IOC). The VOC/VOA analyses performed detected no quantifiable levels of organic chemicals in Wells No. 3 and 4. The IOC analyses performed found the water from Wells No. 3 and 4 to meet all general guidelines. WELL SITE SURVEY METHODS AND PROCEDURES The detailed well site survey consists of an aerial photographic map and inventory sheets (Appendix B), that relate information about potential sources, routes, and possible problem sites to your water supply wells. The location of potential sources, routes, possible problem sites, water wells minimum setback zones and the 1,000 foot survey area are all displayed on the aerial photographic map. The first page of each survey consists of a summary description and geologic profile for each well. The second and following pages of the survey inventory units within and bordering a 1,000 foot radius of the wellhead. A unit is defined as "any device, mechanism, equipment, or area (exclusive of land utilized only for agricultural production)". The Agency 5-digit well number is associated with unit or map code, and then classified. The classification codes relate to definitions of potential contamination sources and routes as defined in the Illinois Groundwater Protection Act (see Groundwater Primer pages 18-19). The distance and direction of the unit from the wellhead is also indicated. SURVEY RESULTS AND FINDINGS The well site survey of Ransom was conducted on December 13, 1989 by Gregory White, Environmental Protection Specialist from the Agency's Rockford Regional Office. Mr. White interviewed Clyde Kates at the time of sampling. The following describes the results and findings for Ransom. Ransom Well No. 1 (IEPA #11512) - The survey area is rural consisting mostly of moderate density residential housing, partly of commercial businesses, and partly of row crops. The well is located inside the village hall building on Plumb Street. There are no visible potential sources, routes, or possible problem sites located within the minimum setback zone (2C0 feet). Five possible problem sites are located outside the minimum setback zone, but within the survey area (1,000 feet). These sites are the Allen Township Garage (Map code 1) located 495 feet southwest of the well, the Ransom Convenience (Map code 2) located 260 feet north-northest of the well, the underground storage tank at Stevens Trucking (Map code 5) located 780 feet northeast of northeast of the well, the underground stroage tank at the Farmers Elevator Coop (Map code 7) located 860 feet north-northwest of the well, and Ransom Fertilizer Sales (Map code 8) located 1 ,C00 feet northwest of the well. The Village of Ransom is served by a "wildcat" sewer system. Ransom Well No.2 (IEPA #11513) - The survey area is rural consisting mostly of moderate density residential housing, partly of commercial businesses, and partly of row crops. The well is located behind the village hall building on Plumb Street. There are no visible potential sources, routes, or possible problem sites located within the minimum setback zone (200 feet). Five possible problem sites are located outside the minimum setback zone, but within the survey area (1,000 feet). These sites are the Allen Township Garage (Map code 1) located 470 feet southwest of the well, the Ransom Convenience (Map code 2) located 300 feet north-northest of the well, the underground storage tank at Stevens Trucking (Map code 5) located 810 feet northeast of northeast of the well, the underground stroage tank at the Fanners Elevator Coop (Map code 7) located 900 feet north-northwest of the well, and Ransom Fertilizer Sales (Map code 8) located 1,000 feet northwest of the well. The Village of Ransom is served by a "wildcat" sewer system. Ransom Well No. 3 (11514) The survey area is rural consisting mostly of row crops and partly of moderate density residential housing. The well is located near the new water works at the northest corner of town. There are no visible potential sources, routes, or possible problem sites located within the minimum setback zone (200 ft.). Two possible problem sites are located outside the minimum setback zone, but within the survey area. These sites are the Glenn McCann Trucking Company (Map code 4) located 900 feet west of the well and their underground storage tank (map code 3) located 970 feet west of the well. The village is served by a "wildcat" sewer system. Ransom Well No. 4 (11515) The survey area is rural consisting mostly of row crops and partly of moderate density residential housing. The well is located near the new water works at the northest corner of town. There are no visible potential sources, routes, or possible problem sites located within the minimum setback zone (200 ft.). Two possible problem sites are located outside the minimum setback zone, but within the survey area. These sites are the Glenn McCann Trucking Company (Map code 4) located 825 feet west of the well and their underground storage tank (map code 3) located 900 feet west of the well. The village is served by a "wildcat" sewer system. SUMMARY The well site survey conducted located several possible problem sites outside the minimum setback zones but within the survey areas of the wells. Sampling and monitoring to date has detected no contamination in the groundwater utilized by the facility. The Illinois Environmental Protection Act provides minimum protection zones for your wells. These minimum protection zones are regulated by the IEPA. The Act also authorizes county and municipal officials the opportunity to provide maximum protection up to 1,000 feet. The responsibility for the control would then be assumed by local officials through adoption of a maximum setback zone ordinance. Maximum setback zones prohibit the siting of new potential primary sources of groundwater contamination. A mnaximum setback up to 1,000 feet could expand the regulatory coverage of certain existing and new activities. These controls could be implemented upon the adoption of proposed regulations by the Illinois Pollution Control Board. RECOMMENDATIONS The Agency strongly urges the Village of Ransom to consider establishing a maximum setback zone for its wells. The Agency has prepared a "Maximum Setback Zone Workbook" which provides detailed case studies of how to establish maximum setback zones. In addition, technical assistance is available from the Agency and the Illinois State Water Survey. The Agency urges the Village of Ransom to properly abandon Wells No. 1 and 2 pursuant to 77 Illinois Administrative Code 920.120.
