r <br /> SCOPE OF WORK <br /> This section describes the work proposed to initiate the assessment of soil hthology, and soil and <br /> groundwater contamination. It is this professional's opinion that the proposed assessment <br /> technology (cone penetration testing [CPT) and hydropunch) could potentially reduce total <br /> project costs and/or increase the quantity of information obtained. However, it is possible that <br /> site specific conditions exist (e.g hardpan) that will prohibit the use of CPT. If CPT is not <br /> viable at this site, SJCEHD will be notified, monitor well and boring locations will be proposed, <br /> and Task 2 initiated. <br /> Task 1: CPT and Hydropunch Survey <br /> Upon workplan approval by SJCEHD, an encroachment permit will be requested from the City <br /> of Lodi, Public Works Department. Underground Services Alert (USA) will be contacted to <br /> "clear" each of the potential locations of underground utilities. Offsite property owners will be <br /> contacted to attempt to obtain access for assessment purposes <br /> Assuming favorable response from each of the above parties, CPT and/or hydropunch probes <br /> will be advanced along a radial grid pattern emmenating from the previous tank excavation <br /> (Plate 3) CPT/hydropunch will be performed by a currently licensed C-57 contractor. <br /> Additional on site assessment locations may be used to better evaluate onsite geology and assess <br /> the potential that the dispensers also may have been a source of contamination <br /> Any soil samples collected during the assessment will be immediately sealed with Teflon' <br /> sheeting and plastic caps, labeled, logged on a chain-of-custody, and stored in an iced cooler <br /> pending transport to the analytical laboratory at the end of the field day. Water samples will be <br /> collected in laboratory supplied 40-m1 VOA bottles, labeled, logged on a chain-of-custody, and <br /> stored in an iced cooler pending transport to the analytical laboratory at the end of the field day. <br /> Equipment being used at multiple assessment locations will be either steam cleaned or washed <br /> with an Alconox solution and rinsed with distilled water Each assessment location will be <br /> pressure grouted with cement/bentonite at the end of each field day. <br /> Upon completion of this phase of the field activities, a interim summary report will be prepared <br /> The report will present a summary of the field activities and analytical data, and propose <br /> locations for monitor wells and at least one boring <br /> Task 2: Boring and Well Installation <br /> This section describes the general protocol which will be used to install the bonng(s) and <br /> monitor wells during the second field phase of this assessment Bonng(s)/wells will be installed <br /> by a currently licensed C-57 contractor <br /> Borings <br /> 3 <br />
