3 PHASE II PLAN DEVELOPMENT AND IMPLEMENTATION <br /> 3.1 General Findings through February 2002 <br /> Sample collection and review through April 30, 2001 revealed that contamination very <br /> likely extends outside the earlier assumed perimeter (to the North and East) of the C2, C- <br /> ' 3 and C-416 or NE corner of the site <br /> Borings were placed at the edge of the site's northern and eastern property boundaries, <br /> the borings indicated petroleum hydrocarbons similar to diesel in the soil between 20 and <br /> 40 FT bgs near the property's edge as well as low levels of extractable petroleum <br /> ' hydrocarbons in the underlying groundwater at about 50 FT bgs <br /> Findings support the presence of a product plume in a north—north easterly direction in <br /> the soil as well as a broader low level contaminated area of groundwater Similarly the <br /> ' petroleum hydrocarbon plume in the groundwater extends in the same direction beyond <br /> the property line <br /> A ground water sample was collected from MW-1 in January 2002 and depths to the <br /> water table were measured at selected points surrounding the site Results have been <br /> amended to Appendix D, "LABORATORY RESULTS" The 1gt quarter 2002 January <br /> 2002 sample indicated a decrease in Purgeable Hydrocarbons from 56 ppb in the 2nd <br /> ' quarter of 2001 to below non-detect (50 ppb) levels, while Unidentifiable Extractable <br /> Hydrocarbons dropped to 1 2 ppm from 2 4 ppm measured in the 2nd quarter of <br /> 2001 Reference February 28,2002 Addendum to Barber's Interim Findings Report <br /> (Appendix H) <br /> 1 <br /> �1 <br /> 3-1 <br /> P <br />
