The report summarizes information about your facility and samples collected and analyzed from your welKs). The well site survey provides an inventory of the area around the welKs) 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 MELL SITES The Village of Ridgway obtains its water from three drift wells. Wells #1 and #3 are the main supply wells with Well #2 primarily used to supply an agricultural - chemical facility. The wells provide an average of 113,000 gallons per day to 542 services. See Table I for a description of each well. The surficial geologic susceptibility rating for all three wells is A2. The aquifer is overlain by sandy sediments with a moderate to high permeability. Permeability is a measure of the ability of a soil or sediment to transmit fluids. A complete description and geologic profile is found in the Facility Wells Report (Appendix C). __ Minimum Maximum Capacity Specific Well Well Setback Setback (gpm) Capacity Depth Logs (ft.) (ft.)

A - Active GROUNDWATER SAMPLING AND MONITORING HISTORY Rldgway Wells #1 and #3 were sampled on July 7, 1987 as part of a Statewide Groundwater Monitoring Program. The samples were analyzed for inorganic chemicals (IOC) and volatile organic/aromatic compounds (VOC/VOA). The wells were additionally sampled for synthetic organic pesticides (SOC) on July 19, 1988. VOC/VOA analyses did not detect quantifiable levels of any organic compounds. SOC analyses did not detect any pesticides/herbicides. IOC analyses indicate that both wells have slightly elevated arsenic levels, ranging from 55 to 83 parts per billion. This is above the Maximum Allowable Concentration (MAC) for arsenic, set at 50 ppb in drinking water, but below the General Use Guideline for raw water of 1,000 ppb. More information on arsenic may be found in Appendix E, complete analyses are in Appendix D. 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 a 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 Ridgway well site survey was conducted on November 28, 1990 by Wade Boring from the Agency's Springfield office. The following describes the results and findings for the Ridgway public water wells. Ridawav Well #1 (lEPA #70410) The survey area is mostly urban. The area is a mixture of residential and commercial. There is one potential secondary source and six possible problem sites within 1,500 feet of Well #1. The potential secondary source is Tri-County Fertilizer (map code 7) 230 ft. SW. The possible problem sites are an abandoned gas station (map code 4) 870 ft. NW, Veach Oil (map code 5) 550 ft. NNW, Wills 76 (map code 6) 470 ft. N and FS (map code 8) 450 ft. SSE, Durham Hardwoods (map code 3) 1,050 ft. W and bulk fuel (map code 10) 1,050 ft. SE. Ridqwav Hell #2 (lEPA #70411) The survey area is mostly urban. The area Is a mixture of residential and commercial. There is one potential secondary source and six possible problem sites within 1,500 feet of Well #2. The potential secondary source is Tri-County Fertilizer (map code 7) 220 ft. SW. The possible problem sites are Durham Hardwoods (map code 3) 1,050 ft. W, an abandoned gas station (map code 4) 880 ft. NW, Veach Oil (map code 5) 560 ft. NNW, Wills 76 (map code 6) 480 ft. N., FS (map code 8) 440 ft. SSE and bulk fuel (map code 10) 1,040 ft. SE. Ridqwav Well #3 (lEPA #70412) The survey area is mostly urban. The area is a mixture of residential and commercial. There are two potential secondary sources and four possible problem sites within 1,500 feet of Well #3. The potential secondary sources are Veach Oil (map code 5) 280 ft. SW and Will 76 (map code 6) 290 ft. S. The possible problem sites are Durham Hardwoods (map code 3) 1,150 ft. WSW, an abandoned gas station (map code 4) 700 ft. WSW, Tri-County Fertilizer (map code 7) 980 ft. SSW and FS (map code 8) 1,200 ft. SSE. SUMMARY The well site survey conducted indicates that there are potential sources/sites that could pose a hazard to groundwater utilized by the Ridgway public water wells. Five sites with below ground fuel storage; an abandoned gas station, Veach Oil, Wills 76, Tri-County Fertilizer and FS. Two sites with above ground storage of fertilizers and pesticides; FS and Tri-County Fertilizer. One bulk fuel storage area. One woodworking company. The Illinois Environmental Protection Act provides minimum protection zones for your wells. These minimum protection zones are regulated by the lEPA. The Act also authorizes county and municipal officials the opportunity to provide maximum protection zones up to 1,000 feet. The responsibility for the controls 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 up to a distance of 1,000 feet from the well head. In addition, a maximum setback zone could expand the regulatory coverage of certain new and existing activities. These controls could be implemented upon the adoption of proposed regulations by the Illinois Pollution Control Board. RECOMMENDATIONS The Agency strongly urges Ridgway to consider establishing maximum setback zones for its wells. The Agency has prepared a "Maximum Setback Zone Workbook" which provides detailed case studies of how to establish a maximum setback zone. Technical assistance is available from the Agency and the Illinois State Water Survey.
