Independent Test Results

The City has received the sample results from the independent testing completed in September 2025.  

The lead and copper sampling consisted of 30 samples for IEPA compliance, and an additional 21 samples were collected as part of the settlement agreement. Of the 51 samples taken, 0 had lead levels that exceeded the EPA’s Lead Action Level of 15 ppb. The City’s 90th percentile value (for EPA compliance) was <1.0 ppb.  For reference, last year’s (2024) sampling resulted in a 90th percentile value of 4.5 ppb. In the City’s view, these results continue to be in line with historical reported values.  All residents that participated in the sampling were mailed their results along with information regarding health effects of lead, steps to reduce exposure and contact information for questions. The results can be found on the link Lead and Copper Results 2025.

The independent chlorine testing included samples from 50 locations throughout the City. Results can be found on the link Chlorine Sample Results 2025. When there are instances when samples reveal chlorine levels to be lower than the desired levels, one approach taken by Sycamore’s Water Division is to flush hydrants in the impacted area until a satisfactory residual is detected.

This concludes the independent testing per the settlement agreement.  Since 2023, 154 samples were independently collected and analyzed for lead and copper by an independent contract laboratory.  The City of Sycamore continued to meet the EPA’s lead and copper requirements.  The results confirm that the City’s corrosion control program is functioning properly. 

Water is one of our most vital resources, and its quality is a top priority for Sycamore’s City employees, residents, and businesses. The City believes a key to continued improvements to our water is ongoing communication and collaboration between all involved. Please contact the Public Works Department at 815-895-3545 with any questions or concerns.
