The <br />installation of GW -1A is a separate project which will take place after the installations of the <br />soil gas monitoring wells at Foothill Landfill. <br />Since we will be drilling exploratory borings to find the shallow aquifer, we may encounter <br />different issues in the field, thus inspection time specified may change. <br />The first work location we will start will be on the North West end of the landfill i.e. close to <br />Corral Hollow Rd. After we have completed work there, we will then move to the South <br />western end of the landfill (By Corral Hollow Creek) <br />We would like to grout the temporary borings the same day to avoid any caving of the borings. <br />The borings that we will determine suitable for establishing our permanent ground water well <br />will be established the next day but covered with plywood and sealed as described in our work <br />The driller has informed me that they should be ready for inspection around 2.30pm to grout <br />temoorary borings on Monday Nov 26th. The driller will notify you on site the approximate time <br />they would be ready for inspection to establish the ground water well the next day. <br />Tt�e —same work procedure and inspection scfte—d–u Fin—gwilf be applied to locate IT.11'1-g aF0 <br />inspection time will be notified to you on site.
