N'alchrr <br />Execmive Direclar <br />Michael B. Long <br />Divi,ion Ducclor <br />Ms. Ford owns the land at the southeast corner of 104th Avenue and McKay Road. She reports that <br />difficulties with her well began when CAMAS constructed a ditch to divert water away from the <br />slurry wall construction project. The well water became muddy, and subsequently the formation in <br />the well bore collapsed. She further states that since the slurry wall was installed, a pond has Formed <br />on a neighbor's land. Ms. Ford hypothesizes that the construction and operation of the diversion <br />ditch drew down the alluvial aquifer. The water table was then elevated to higher than natural levels <br />due to mounding behind the slurry wall. She believes this fluctuation in the water levels caused her <br />well to collapse. The well was drilled in the 1920s or thereabouts and is cased to 35 feet. The well <br />itself is reported to be several hundred feet deep. Given the age of the well it is likely that it is not <br />sealed from the alluvial aquifer or surface water. <br />Ms. Ford reports that CAMAS has been contacted, that they inspected her well and told her that their <br />activities did not cause the well to collapse. She believes that it is too great of a coincidence that her <br />previously problem free well collapsed at the exact time of the slurry wall operation. She stated that <br />CAMAS had at one time offered to monitor the well prior to and during operation of the gravel pit, <br />but that CAMAS never followed-up on the offer. In a brief review of the file, I determined that <br />CAMAS has committed to a ground water monitoring plan and to provide results in the annual <br />reclamation report. The first annual report was submitted 9/19/00, but does not include any ground <br />water monitoring data. <br />I told Ms. Ford that if she wrote a letter describing her situation, that we would schedule a high <br />priority inspection to be conducted within no more than 30 days, and would investigate the matter. <br />Ms. Ford no longer lives on the property at 104t'' and McKay, but gave her permission for the Division <br />to access the property and inspect the well pit, etc. She stated that the old farmhouse on her property <br />had burned down and there is now a mobile home on the land. <br />cr.
