There were also low <br /> level <br /> detections of EDB found in the surface water of the Quashnet River in Mashpee. <br /> Monitoring orin Well No.. 132 was installed approximately 2,000 feet northeast of Johns <br /> Pond in Mashpee on My. <br /> onda Preliminaryresults showed EDB in groundwater starting <br /> round surface down to 190 feet below ground surface. The maximum <br /> at �� feet below g <br /> level detected was 15.5p per er billion at 80 feet. The safe drinking water standard is <br /> 0.02 parts per billion. <br /> orin wells have been installed, one at 500-feet to the <br /> Two additional groundwater monit g <br /> 3'1 showed preliminary results of EDB up to 5.4 <br /> north of well No. 13�.
