1 Ambient Ground Water Quality Monitoring Program Inorganic Ground Water Quality Time Series Ground Water Quality Report Division of Drinking and Ground Waters Report Date: /2/26 This Ground Water Quality Report summarizes the raw (untreated) inorganic ground water history for a single well (see box below). Time series graphs are a concise method of visualizing the geochemical variability within a water well over me. System Name: London Wellfield Well Number: 7 Ambient Well ID: 39MAD73 County: Madison Casing Length ( ) Well Depth ( ) 72 Major Lithology: Sand and Gravel Geologic Se ng: Complex In the graphics on the following pages, the sample dates are shown on the horizontal axes, and the parameter concentrations are indicated on the vertical axes. As an aid to the reader, Maximum Concentration Levels (MCLs in red text) and Secondary MCLs (SMCLs in blue text) have been noted on the graphs where applicable. Action Levels (ALEs, in red text) have also been indicated for lead and copper results. While MCLs, SMCLs and ALEs are convenient benchmarks for interpreting water quality data, please note that they apply strictly to public water supply distribution water (post treatment), and not to the raw, untreated ground water samples represented in this report. Current Reporting Limits are listed for each graph. Several parameters have multiple reporting limits over the period of data collection, which are obvious in the time series. The Ambient Ground Water Quality Monitoring Program (AGWQMP) was established by Ohio Environmental Protection Agency to characterize Ohio's ground water quality in order to enhance water resource planning and prioritize ground water protection activities. Managed by the Division of Drinking and Ground Waters, the AGWQMP database now contains some 2 active water supply wells across Ohio. For additional information or answers to questions concerning the Ambient Ground Water Quality Monitoring Program, contact Christopher Kenah or Michael Slattery at (64) at Ohio EPA in Columbus, Oh., or us at: gwq@epa.ohio.gov The Division of Drinking and Ground Waters (DDAGW) is providing information via this Web page as a public service. While Ohio EPA believes this information to be reliable and accurate, some data may be subject to human, mechanical, or analytical error. Because of the variability inherent in ground water data, caution must be taken in extrapolating point data beyond the collection area. The accuracy, completeness, suitability, and conclusions drawn from the information presented here are the sole responsibility of the user. W. Town St., Ste. 7 P.O.
