Each bottle will <br /> contain 60 ml of groundwater with-100 ml for headspace. The procedure will include <br /> three time points: beginning (T = 0 days), intermediate (T = 30 days) 'and end (T = 45 <br /> days). <br /> Case 1 will contain groundwater with 100% oxygen in the headspace and nutrients will <br /> be added; <br /> Case 2 will contain groundwater with 100% oxygen in the headspace and nutrients will <br /> not be added; and <br /> Case 3 will contain groundwater with air in the headspace and nutrients will not be <br /> added. This is the monitored natural attenuation case. <br /> COMMENTS ON ITRC <br /> For chemical oxidation (Fenton's Reagent, ozone, potassium permanangate, etc.), the ! <br /> ITRC recommends the following analysis: <br /> Groundwater parameters: <br /> dissolved organic carbon (DOC) <br /> alkalinity <br /> orthophosphates <br /> total (Kjeldahl)nitrogen <br /> Nitrogen as Nitrate <br /> total phosphorus <br /> dissolved contaminant(e.g.,BTEX) <br /> ORP <br /> pH <br /> DO <br /> Soil parameters: <br /> phospholipid fatty acids(PLFA) <br /> heterotrophic plate counts (or other method-of identifying microbes) <br /> foc (fraction of soil that is organic carbon) <br /> contaminant (e.g., chloroethenes) <br /> NOD <br /> For monitored natural attenuation and bioremediation, the ITRC recommends the. <br /> following analysis: <br /> Main Office:229 Tewksbury Ave.,Point Richmond,CA 94801 Tel:510-232-2728;Fax:510-232-2823;May 20,2006 <br /> 2 <br /> II <br /> • i <br />
