Pagel of 3 <br /> Mike Infurna [EH] <br /> From: Toni.Pezzetti@CH2M.com <br /> Sent: Monday, February 04, 2008 6:21 PM <br /> To: Mike Infurna [EH] <br /> Subject: RE: Tracy Permits <br /> Uh-oh. Sorry about the delay and thanks for the reminder that I owed you something. <br /> HP-8 <br /> Installed: January 18, 2008 <br /> Total depth: 25 feet(bottom split spoon 25-26.5) <br /> Well screen: 4"sch 40 PVC 0.020 slot 13-23 ft bgs (bentonite chips 23.5-25 feet) <br /> Sand: 23.5 to 10.5 ft. Cemex Lapis Lustre#3 Monterey sand 7 bags. Sand surged and replenished to 10.5 ft <br /> bgs. <br /> Fine sand: 10.5 to 10 ft. RMC#60 <br /> Bentonite chips: 1/2 bag cetgo pure gold medium chips(other 1/2 of bag used at bottom of hole), 1/2 bag baroid <br /> 3/8" hole plug. Hydrated. After 20 minutes, water still visible on top of bentonite. Began mixing cement. Water <br /> still visible, cement emplaced about 7-8 minutes later. <br /> Cement: Basalite type II-V, 3 1/2 bags. <br /> Protective, locked casing installed with pad and 3 crash posts. <br /> Just for your information -we installed the well shallower because we encountered some of the tightest clay I've <br /> ever seen (it had to be cut off the augers and came off in intact sheets). We'd had silty clay at between 15 and <br /> 16.5 feet(where we hit water)and then went back into the tight, very dry clay. Based on the previous 2 holes, I <br /> expected the sand below 30 feet. Because we were downgradient of the WWTP, and upgradient of Spreckles, I <br /> went with caution. <br /> Let me know if there's anything else. The wells have not been developed yet because it has been too wet. That <br /> is scheduled for February 19. <br /> Thanks again. <br /> Toni <br /> From: Mike Infurna [EH] [mailto:MInfurna@sjcehd.com] <br /> Sent: February 04, 2008 1:12 PM <br /> To: Pezzetti,Toni/SAC <br /> Subject: FW: Tracy Permits <br /> I still need the well specs... <br /> the money for field inspections I saved you is building up on these 'correspondence'emails. <br /> From: Mike Infurna [EH] <br /> Sent: Thursday, January 31, 2008 11:24 AM <br /> To: Toni.Pezzetti@CH2M.com' <br /> Subject: FW: Tracy Permits <br /> Toni, <br /> please get me the well construction specs for the last well you placed. <br /> From: Mike Infurna [EH] <br /> Sent: Wednesday, January 02, 2008 1:00 PM <br /> 2/5/2008 <br />
