• Discontinue sampling of MW-5 That well was placed by Nomellmi Construction Co , <br /> and is being monitored by their consultant We will obtain water depth data as before in <br /> order to determine gradient direction <br /> • Perform EPA 601 only on MW-4, MW-7, MW-8, &MW-9 It has not been detected in <br /> any of the other wells <br /> • Discontinue analysis for MTBE, it has only been detected in MW-5, which is being <br /> sampled by another firm <br /> • Include MW-9 in the next sampling event, which is due in February, 1997 However, <br /> that well is located offsite on property occupied by JM Equipment, and owned by <br /> others, monitoring of that well is their responsibility We will attempt to coordinate <br /> our activities with their consultant to avoid duplication of work <br /> • We also propose to change to semi-annual monitoring after the next sampling Since <br /> the major sources of contamination are offsite, and it is assumed they will have to be <br /> monitored on a quarterly bans, we see no need to do so on this site <br /> We would appreciate if you would respond to the above proposals in order that we can <br /> make needed changes in our sampling procedures <br /> W er & Associates <br /> cc zabeth Thayer, RWQCB <br /> W W Miles - <br /> �RED GEpzO <br /> R Lautze C) <br /> J Welch Q WeLA S HUNTER <br /> Independent Trucking '�� W¢ <br /> Geo Properties NO 860 <br /> L Bradfish oF cAUF° <br /> z <br />
