2014 Water Quality Chart The City of Independence Water Department performs over 50,000 tests each year before, during, and after treatment. In addition, further tests are conducted at independent, certified laboratories. Regulated compounds listed below show the Federal Maximum Contaminant Level (MCL). Unregulated compounds show only the results of tests done on City of Independence water. It is the City of Independence Water Department's pleasure to provide this information to our customers. If you have any questions about this chart, please call us at 816-325-7708. Organic Compounds There are a number of organic compounds that are of concern in drinking water. This group includes volatile organic compounds that vaporize easily and are called VOC's; pesticides and herbicides that run off or percolate through soil to groundwater supplies; and compounds that occur as a by-product when water is disinfected.
