Oswego’s drinking water source is groundwater, delivered by eight wells.  All wells are considered deep wells and draw water from a sandstone aquifer.  While these aquifers provide a high-quality water, they often contain elevated concentrations of naturally occurring Radium-226 and Radium-228.  The Village of Oswego utilizes a filtration process for radium removal.  The radium level at each well is below the Environmental Protection Agency’s (EPA) maximum allowable level of 5 picocuries per liter (pCi/L). Fluoride levels from the deep sandstone aquifer meet EPA and Illinois Department of Public Health standards for drinking water and no additional fluoride is added at any of the well sites.

  • Well No. 5 - Removed from service June 22, 2000.
  • Well No. 6 is in the Fox Chase subdivision next to the 300,000-gallon water tower.  This well produces 955-gallon per minute.
  • Well No. 7 is in the Ogden Falls subdivision next to the 1.5 million gallon water tower. This well produces 960 gallons per minute.
  • Well No. 8 is located on Grove Road ¼ mile south of Plainfield Road.  This well produces 916 gallons per minute. Well #9 is located at 700 Yoakum Boulevard and produces 1,055 gallons per minute.
  • Well No. 10 is located at 700 Cole Avenue and on site is a 1.5 million gallon water tower. This well produces 1145 gallons per minute.
  • Well No. 11 is located at 6701 Tuscany Trail off of Orchard Road and on site is a 1.5 million gallon water tower.  This well produces 1181 gallon per minute.

All well water is treated to remove high levels of Radium, chlorinated to kill any microbial contaminants that may be present, and treated with polyphosphate for corrosion control and mineral sequestration prior to being delivered into the distribution system.
