DVCW-4: The injection potential of the formation was investigated by taking the well off-line for several hours and injecting water into the formation over a range of pressures. Approximately 40 psi was necessary to inject water at a rate of IO gpm. Subsequent to the test. the well was returned on-line and the injection capacity was improved. The injection capacity was consistent with the extraction rate of approximately 3 gpm. 8.0 Project Quality Assurance: NI A 9.0 Other Technical Notes/Concerns: NIA 10.0 Operational Data Pumping and VCW Concentration Data; Samples collected on 5/6/03 and 5nt03 (all wells except SVCW-3) Averaged flow rate data from 5/16/03 to 5/23/03 during past week of annual O&M Total flow data from 3/20/03 to 5/23/03 during 30-day start-up and annual O&M VCWd taf rom samo1 es on a 5/6/03 d 5/7 /03 an Ave. Flow Rate Total Flow PCE TCE Well# (~nm) (~al.) nnb nnb SVCW-1 0.00 1,209 170 8.1 SVCW-2 0.93 67,283 12 0 SVCW-3 0.66 65,267 55 2 DVCW-1 2.75 140,312 200 18 DVCW-2 1.61 98,588 110 6.5 DVCW-3 2.54 135,794 1,900 96 DVCW-4 0.02 38,018 1,600 110 Total System 8.51 526,776 Avg.

Representatives from EA and the manufacturer met onsite on 22 and 23 April 2003 to investigate and troubleshoot the system. The source of the problem was determined to be insufficient flow through the air-stripping unit. The resolution was to reconfigure the vapor system piping and replac.e the two existing carbon units with a larger unit capable of handling a higher flow rate. The equipment change-out and piping reconfiguration will be completed by 30 April 2003. The system will be restarted and operated for five days on an interim basis to verify proper operation of the unit. During this five-day period influent and effluent samples will be collected twice per day. One sample from each of the first three days will be analyzed • within a 24-hour turn around time (TAT) period. The remaining samples will be analyzed within a normal IO-day TAT.

Subsequent to re-installation of the downwell assembly the well was restarted and water was observed leaking from the high voltage wire casing and into the pump switch box in the well vault. The downwell pump and packer assembly was removed and inspected on 02 April 2003. The groundwater pump and level transducer were not working properly and will be replaced.

The system shall be operated for one year in a manner that optimizes a balance between reduced cleanup duration and a reduced remedial cost while minimizing the treatment of uncontaminated groundwater. 2.0 Previous Period Action Summary: 23 December through 27 December 2002 ■ Continued general construction activities ■ Continued well drilling at Parkdale (DVCW-2 and DP-2) 3.0 Reporting Period Action Summary: 30 December through 03 January 2003 ■ Continued general construction activities -trenching layout ■ Continue well drilling at Parkdale (DVCW-3 and DP-3) 4.0 Planned Accomplishments for Next Period: 06 January through 10 January 2003 ■ Continue general construction activities ■ Initiate horizontal boring between DVCW-3 and SVCW-3 (pending EPA and COM approval) ■ Initiate standard trench excavation for Roper well piping to building ■ Initiate and complete treatment system building installation ■ Complete well drilling at Parkdale (DVCW-4 and DP-4) 5.0 Personnel Issues: NIA 6.0 Subcontract Issues: NIA • 7.0 Pending Technical/Operational Issues: NIA ~cckly Project Status Report 78 North Belmont PCE Site 30 December through 03 January 2003 Page 2 of2 EA has submitted (12/20/02) a proposed horizontal boring procedure to EPA and COM for review and approval. The horizontal boring would replace traditional trench installation between DVCW-3 and SVCW-3. 8.0 Project Quality Assurance: N/A 9.0 Other Technical Notes/Concerns: N/ A PROJECT FINANCIAL AND SCHEDULE INFORMATION 1.0 Contract History: Original Contract Amount: $ I 187 427 76 Total for Modifications Issued: $ 254 213 76 Current Contract Price: $ I 287 291 02 Pending Modifications: =$ ___ ~0~0=0~-- Expected Final Contract Order Amount: ~$_1..._4.,_4,._,ls.c6e..4,.,1~3'-"2~-- 2.0 Change Order History and Status: Change Order# I: Re-Design of Shallow Test Well ($56,910) Change Order #2: Electrical Disconnect at Well Abandonments ($2,640) Change Order #3: Additional VCW Sampling for VOCs ($809.76) Claim #1: Installation of Deep Test Well System ($39,505.00) Change Order #5: Revised Construction for Full-Scale System ($154,350.00) 3.0 Project Financial Status: On schedule 4.0 Financial Items/Concerns: N/A 5.0 Project Schedule Status: Due to weather delays experienced 12/3 through 12/6 the well installation and housing tasks will be extended approximately 3 to 4 days.
