Site conditions led <br /> to a change in the scope of work, and four monitoring wells were installed on site <br /> instead of three. SJC/EHD approved this change in the field . <br /> The installed monitoring wells were not developed until September 9 , 2003. <br /> Following development of the wells , discrepancies were noted between the total <br /> depth of the wells as built and the total depth tagged by the developer. <br /> Specifically, monitoring well MW-4 had been reported to SJC/EHD as being built to <br /> total depth of 100-feet below surface grade (bsg ), but tagged after development at <br /> 90 . 1 -feet bsg . Likewise , MW-1 was built to 704eet bsg but tagged after <br /> development at 63.8-feet bsg ; and MW-3 was built to 65-feet bsg but tagged after <br /> development at 61 . 35-feet bsg . Monitoring well MW-2 was the only well that <br /> tagged after development close to the total depth built, at 64.5-feet bsg versus 65- <br /> feet bsg . The discrepancies in well design versus actual field measurements must <br /> be investigated and satisfactorily explained to this agency. <br /> Quarterly groundwater monitoring and sampling of your contaminated <br /> underground storage tank site must be initiated immediately, and must continue <br /> until directed otherwise by this agency. The presence of free product petroleum <br /> hydrocarbons was reported in MW-1 during development. This finding must be <br /> verified , and if substantiated , interim remediation for removal of the free product <br /> must begin immediately. SJC/EHD must be notified within fourteen days of the <br /> date of this letter that quarterly monitoring has been scheduled , and that the issue <br /> of free product in MW-1 has been addressed . In addition , California Code of <br /> Regulations Section 2729 . 1 Water Code Section 13196 , commonly referred to as <br /> i AB 2886 , requires that all laboratory analytical results be electronically submitted <br /> d to GeoTracker — the State Water Resources Control Board database program . <br /> Electronic transmission of laboratory analytical results to GeoTracker must be <br /> initiated immediately. <br /> i <br />
