aquifer is relatively low, but not nonexistent. Surface releases of contaminants within the DWSMAs, <br />particularly if the releases were to be large and not cleaned up in a timely manner, could pose some risk <br />to the source water aquifer. In addition, unmaintained, damaged, poorly -constructed, unused, or <br />incorrectly abandoned wells could provide a direct route for contaminants to enter the source water <br />aquifer. A spill very dose to such a well would pose more of a risk to the source water aquifer than a spill <br />in one of the DWSMAs far from such a well. <br />As discussed by MDH (2018), the DWSMAs were delineated to encompass the zones in which <br />groundwater travel time to the Ramsey municipal wells is ten years or less. The DWSMAs are defined by <br />geographically identifiable features. The East DWSMA extends beyond the Ramsey city limits into a <br />portion of the city of Anoka. <br />Potential contaminant sources within the DWSMA identified through the PCSI include wells, storage tank <br />sites (including LUST sites), potential Class V well locations, chemical storage locations, spill locations, and <br />sites brownfields sites potentially associated with contaminants that may not fit into one of the other <br />categories. In addition, railroad and highway corridors are present within the DWSMAs. These corridors <br />are a potential location for contaminant spills. These potential contaminant sources will be considered <br />when developing the management strategies for the Ramsey DWSMAs. <br />C-13 <br />
