Observe groundwater accumulation in groundwater monitoring tube installed on 10/25/02. PRIMARY CONTACTS DURING THE SITE VISIT 1. Mr. Michael Foster, Homeowner MICHAEL L. FOSTER & ASSOCIATES 1. Mr. Gordon Seversen, P.E., Senior Engineer Z'! FINDINGS AND ACCOMPLISHMENTS A groundwater monitoring tube was installed at 8:45 am on Friday, October 25 at a location shown on the as -built site plan. The perforated section was installed at 9.0 feet below existing grade where bedrock was encountered. I observed the installation and found it acceptable. On Friday, November I at 3:30 pm, I measured the tube for groundwater level: No groundwater was observed. A 2-inch layer of mud was found at the base of the tube. I advised Mr. Foster to cover the monitoring tube at his convenience.
