Shuron NPL Site: Observations/Lessons Learned

Success at increasing DOC in wellsAquifer buffering capacity rendered pH adjustment attempts unsuccessfulBioaugmentation unsuccessful because of low pH/aquifer bufferingBiofouling reduced injection effectivenessSuccessful where pH = 6 or aboveDid not work in areas of reduced pH
