Minutes - Regular Meeting <br /> Solid Waste Advisory Board <br /> March 5, 2009 <br /> Approved April 2, 2009 <br /> oxidation actually oxidizing bacteria cells . I prefer to do something the bacteria will <br /> enjoy . <br /> Sue Dayton, I live in Alamance County, next to a landfill as well . Of the contaminants <br /> listed, would any of those not be broken down by the method you described ? <br /> Ford replies no . Most will be broken down by one or both . There are some <br /> exceptions, like propane, but we don' t see that. Everything that we are seeing here is <br /> very amenable . <br /> Dayton asks of those containments how do you rate those for being degraded by this <br /> method . <br /> Ford states that among those 123 that include various herbicides, pesticides, PCBs and <br /> a lot of things that are recalcitrant and harder to treat with these methods there are <br /> other methods . We work with about 47 landfills and we almost never see herbicides <br /> and pesticides that we can verify . I don' t know if these oxidants would or would not <br /> oxidize these herbicides and pesticides because I' ve never had to deal with them . <br /> Chris Heaney, recent graduate of UNC School of Public Health . Your status sheet for <br /> natural attenuation is based on the decline you show of some of the materials but <br /> some of the toxic compounds appear to be going up , is that the reason for the test <br /> wells ? <br /> Ford states that we anticipate the natural attenuation will ultimately take all the <br /> constituents down to the NC Protection Standard given enough time . Rather than <br /> wait, the County expressed interest in accelerating the whole process along the <br /> eastern edge of the property to clean it up sooner rather than later . <br /> Heaney asks if the injection wells is the response that will be proposed . <br /> Ford states that it will be proposed and the next step will be to submit a corrective <br /> action plan. We will have selected appropriate measures from the ones I went <br /> through . Essentially we are selecting all of them saving direct oxidation for last in <br /> case the other stuff doesn t work . That is the last step that will go into the corrective <br /> action plan . <br /> Heaney asks if there is a priority of the approach you mentioned . At what point will <br /> you release information about a recommendation about whether it is natural <br /> attenuation or the injection approach. <br /> 4 <br />
