Total depth of the well was approximately 120 feet bsg The video survey log is included <br /> in Appendix B ' <br />' 2 4 DOMESTIC WELL ABANDONMENT <br /> On 16 October 2000, domestic well DW-2 was abandoned by Clark Well, Inc (CWI) and WWT <br />' utilizing blast perforation and casing ripping techniques Explosive charges and projectiles (chrome- <br /> alloy steel round bullets) were attached to an explosive cord at fixed intervals and lowered into the <br /> well Explosive cord extended to total depth of the well The well was then filled to surface grade <br />' using neat cement and the charges were detonated Perforations introduced into the well casing by <br /> the projectiles and explosive cord provided pathways for the cement to fill voids and cavities <br /> extending into the formation The well was again filled to surface grade with neat cement All work <br />' was overseen by AGE and PHS-EHD-personnel <br />' 3.0. FINDINGS <br />' Hydrocarbon-impact to ground water was inferred from laboratory analysis and field observations <br /> Ground water elevation was determined by subtracting the measured depth-to-water-from the <br /> surveyed casing elevation <br /> 1 <br /> Advanced GeoEnvironmental,Inc <br />
