Analysis of water sampling conducted in 2016 to monitor lead and copper levels has concluded 90th percentile levels to be 4 parts per billion (ppb) for lead and 896 ppb for copper – significantly lower than the 13 ppb lead and 1200 ppb copper levels reported in the previous round of sampling in 2014.
It is important to note that these levels represent the 90th percentile of all samples collected, meaning that 90% of the samples were at or below 4 ppb for lead and 896 ppb for copper. The EPA requires action when the 90% percentile level is at or above 1300 ppb for copper or 15 ppb for lead.
148 homes were sampled in 2016 (up from 59 in 2014) which resulted in a better overall representation of the water system. In addition, all samples collected were taken by a water certified City employee instead of relying on homeowners, resulting in more consistent sampling.
The City’s pro-active Lead and Copper Program not only includes water quality monitoring, but also a corrosion control program to minimize the likelihood that lead can leach into the water supply, a lead water service replacement program, and a public education program.
The 2016 lead and copper monitoring event was the City’s ninth since the enactment of the Lead and Copper Rule in 1992. The City of Kalamazoo’s Public Water System continues to fully comply with the federal and state Safe Drinking Water Act Lead and Copper Rule.
These analytical results and others regulated under the Safe Drinking Water Act will be included in the next annual Water Quality Report (Consumer’s Confidence Report) in July 2017. Free water testing is available to customers of the water system. If you would like to have your water test, please call (269) 337-8550.
