30 January 2014 AGE Project No . 99-0682 Page 27 of 28 WELL DEVELOPMENT Development of the proposed wells will consist of a combination of bailing with a stainless steel bailer to remove the major portion of fine-grained sediment from inside the well , surging to flush out or draw in sediment from the filter pack, and additional groundwater evacuation with a Waterra inertia pump to finish the removal of fine-grained sediment. Developmental purging activities will be continued until field parameters (pH , electrical conductivity, and temperature) have stabilized and purged water is visually sediment-free . EQUIPMENT DECONTAMINATION/WASTE MANAGEMENT All sampling tools will be thoroughly rinsed with clean water after being washed with a solution of Alconox. All down-hole drilling equipment will be pressure washed prior to starting each boring . Rinseate and soil cuttings generated during drilling and groundwater sampling activities will be containerized in properly labeled , Department of Transportation (DOT)-approved 55-gallon drums and stored on-site in an area lacking public access . Disposal alternatives will be evaluated based on the results of soil analysis. ISCO SOLUTION PREPARATION AND INJECTION PROCEDURE Solutions of 5% hydrogen peroxide will be prepared on-site utilizing 200 gallon water totes and water from an on-site source . The totes will be filled will approximately 175 gallons of tap water and 25 gallons of industrial grade 35% hydrogen peroxide. For each tri-weekly injection event one tank, equal to 200 gallons of diluted peroxide solution , will be pressure injected (using sump pumps) into each of the proposed wells ( 13 proposed wells ; total of 2 , 600 gallons injected per event) . It is anticipated that up to four totes will be injected simultaneously into two shallow and two intermediate wells during each daily injection event. The volume of solution that is injected daily or per event may vary based on field acceptance of the material . Injection frequency and volumes will be adjusted based on field conditions and observations . PROGRESS/CONFIRMATION/COMPLIANCE MONITORING AND SAMPLING Performance of progress/confirmation sampling will be completed following the initial four tri-weekly injection events . Progress/confirmation testing will be performed by an OSHA40- hour certified AGE representative. Monitoring and sampling will be performed in accordance with AGE's standard monitoring and sampling procedures (Appendix F). Advanced GeoEnvironmental, Inc.
