This was also pointed out to me by Adam Czarnecki (re an earlier discussion on lead), and having read the bits of SGV10.....I had to agree but I was amazed no comment to this effect was in CLR7. regardles of who is right... would you really get picky about a 10% exceedance? -----Original Message----- From: Andrews, Ken [mailto:[log in to unmask]] Sent: 27 November 2003 11:50 To: [log in to unmask] Subject: CLEA- Hello all, I have a situation where a developer has imported soil with a mean value for lead of 378 mg/kg and a 95th percentile of 480.24 mg/kg which is above the 450 SGV value. The developer is arguing that the SGV value is obtained applying the geometric mean of soil concentration across the site.( table 3.2 SGV 10 ( pg 14 ) and if the geometric mean is used for his sampling result then those values will be much lower than the SGV so the soil is acceptable. Can anyone comment on this argument Thanks Ken ********************************************************************** Southwark Council routinely monitors the content of e-mail sent and received via its network for the purposes of ensuring compliance with its policies and procedures.
