The monitoring, conducted by Doulos <br /> Environmental, included measurements of depth to groundwater, subjective analysis for free <br /> product, groundwater purging and collection of groundwater samples. All field activities <br /> pertaining to events in this report were conducted according to the Ultramar Field Procedures <br /> included in the Attachments. <br /> GROUNDWATER ELEVATIONS <br /> Prior to purging, Doulos Environmental personnel collected depth to groundwater measurements. <br /> Groundwater level data from March 1992 to date are summarized in Table 1. Historic <br /> groundwater levels are presented as an Attachment. On the basis of the current measurements, <br /> groundwater flows to the south (Figure 2) at a gradient of 0.03 ft/ft. Groundwater levels have <br /> increased an average of 1.06 feet compared to the last monitoring event. The groundwater <br /> anomaly observed at MW-25 is likely to be caused by the vapor extraction system operating on <br /> the site. <br /> 94-OWZGMR U.S. operating companies in California, Louisiana, Missouri, and Texas <br /> International operating companies in Australia, Belgium, Brunei,Canada, Germany, Hong Kong, Indonesia, Japan, <br /> Malaysia, The Netherlands, Saudi Arabia, Singapore, United Kingdom, and United Arab Emirates. <br />
