  20. Items for Discussion • SCADA • Data since January 2006-who has it? How can we access it? • Training schedule & website access • Surge tank control of flow rates • PLANTS • Clyde Mason recently did some replanting… • INSTRUMENTS • Gaps in data because of equipment failure, data logger unplugged during constructions, etc. • Inherent measurement problems with instruments • Recycle pumps not working (May 22, 2006) • BIOFIELD • No samples available, except for once in the deepest well • Supply to biofield should be shut off. • DATA AVAILABILITY • Should raw data be put on website? • Or this presentation enough detail. • REPORTS • Under preparation • Any suggestions? • Will seek feedback • OTHER ?
