PRIMA Environmental tmoise/3 <br /> August 25,2004 <br /> • COCs in air: <br /> o 6, standard TAT <br /> Task 3. Effect of Treatment on Secondary Water Quality <br /> The effect of ozonation on secondary water quality parameters [at a minimum pH and <br /> Cr(VI)] will be determined by analyzing untreated water and treated water from Task 2. <br /> ` Other parameters of interest may include arsenic and metals. <br /> Total number of analyses, Task 3: <br /> o 4 for each parameter of concern, standard TAT <br /> Task 4. Fate of Cr(Vl) or Metals <br /> If Cr(VI)or other metal(s) is detected in Task 3, then an additional test to determine <br /> whether these compounds can naturally attenuate will be performed. Four replicates will <br /> be prepared by combining treated groundwater from Task 2 and untreated soil. <br /> Periodically, one replicate will be destructively sampled and the aqueous phase analyzed <br /> ` for Cr(VI) or other metal(s) of concern. <br /> Total number of analyses, Task 3: <br /> r, o 4 for each parameter of concern, standard TAT <br /> Task 5. Report Preparation <br /> r <br /> A final report detailing procedures and observations, results, discussion, engineering <br /> implications, and conclusions and recommendations will be prepared. <br /> SCHEDULE <br /> It is estimated that testing can be completed within 35 days of receipt of samples and <br /> notice to proceed. This schedule should be confirmed with PRIMA Environmental at <br /> least 2 weeks prior to desired start date. <br /> r <br /> By: <br /> Cindy G.
