Page 7 of 14 <br /> Same for the hottest "D" or "T" soil boring data....no soil samples since <br /> supporting that the contam has been cleaned up/removed....The "HA" <br /> soil samples were taken mostly around 3' bgs and NO gw grabs. but <br /> the gw in 1997 was 8' bgs. any soil contam is only single digit feet from <br /> it....12 mg/kg of MtBE with a solubility of 44K mg/I, well it's scary.. j <br /> to be honest, your reports just zoom by the idea any residual soil ! <br /> contam/mass remains onsite. NOT KNOWN to me...can you prove it?.. <br /> I attempted to use the AS well installs of 2002 as proof the soil has <br /> cleaned up. What else can l use?? AS-4 or AS-5 could have been used <br /> with a little stretch, but from what I read in the ERI April 22, 2002 <br /> report of the AS well installs, NO soil samples from ANY of the AS <br /> wells were analyzed !....only drill cuttings/stockpiled soil from the <br /> installation process are in the report.. <br /> am I to understand NO boring samples from the AS wells were <br /> analyzed??? <br /> really? <br /> am I missing something here.?.. <br /> Ben, let me know what happened to the 5500 mg/kg of TPHd in "D-24" <br /> on July 27, 1995.. and the 3400 mg/kg of TPI-Ig in "T-6-4" that also <br /> contained Napth and 2-methylNapth, and the 12 mg/kg of MtBE in HA- <br /> 3 ? <br /> A-3 ? <br /> Can you/COP provide any technical support that this contam has <br /> attenuated/been mitigated/, is NOT still there??? <br /> E <br /> typically, when I can support it, I require confirmation soil borings....I'm <br /> meeting with my PG next weekto.see about it. I'd like to have your <br /> answers by Tues if you can.. <br /> thanks. i <br /> i <br /> have a nice weekend. <br /> From: Chevlen, Benjamin [mailto:Benjamin.Chevlen@stantec.com] <br /> Sent: Thursday, January 06, 20115:07 PM <br /> To: Mike Infurna [EH] <br /> Subject: RE: 76 #5886 <br /> Mike— Section 4.7.3 of Delta's 2006 report documents the collection of sidewall <br /> and tank bottom samples. The sample locations are shown on Figure 10, while <br /> the soil data is included in Table 8; copies of the laboratory report are <br /> .supposedly in Appendix C, however, I did not see them when I scrolled through <br /> the report. Table 8 was also included as page 271 of Stantec's NFAR, <br /> however, a copy of the historical site plan showing the tank pit sampling i <br /> locations was inadvertently omitted. <br /> Benjamin Chevlen,P.G. <br /> 3/14/2011 <br />
