The City of Galesburg, in cooperation with the Illinois Environmental Protection Agency (IEPA), recently completed testing the first 30 samples of the 60 samples that are required to be tested in the spring of 2016. Of these tests, 28 homes tested below the EPA action level of 15 parts per billion (ppb) and two homes tested above the action level. The second group of 30 samples will be collected by May 13, 2016. These test results should be received by the City by May 25, 2016 and will be shared at that time. Additional testing of 60 samples will again be conducted in the fall of 2016.
 
In addition, the water from the pumping station located at 920 West Main Street was tested, which verified that there is no lead in the water being distributed into the City's water main distribution system.
 
The Environmental Protection Agency (EPA) has set the action level for lead in drinking water at 15 ppb. The 90th percentile value is the highest concentration of lead that is exceeded by 10 percent of the sites sampled during a monitoring period. If the 90th percentile value exceeds the EPA action level, the utility is required to notify all customers of the exceedance as well as make adjustments to their corrosion inhibitor program and increase testing of the water.
 
IEPA will do a 90th percentile for all 60 samples after they have all been taken, which will be the official 90 percentile number for this round of testing. For the group of 30 samples taken thus far this spring, the 90th percentile would be 10.5 ppb, which is below the EPA action level for lead in drinking water of 15 ppb.
