EAST HIGHWAY 12 , <br /> LODI <br /> We recently received and reviewed yoz�r revised quarterly ground <br /> water monitoring report. As we requested by phone on 8 July <br /> 1988, a revised report was to be prepared in which the problems <br /> we discussed would be corrected. The revised report still does <br /> not resolve the problems of the original (which was two months <br /> overdue) . Our hope is that, by bringing our concerns about this . <br /> monitoring report to your attention, similar errors will be <br /> avoided in future monitoring reports. <br /> i <br /> Our specific comments about the report are as follows: <br /> - Many monitoring wells were not sampled because they were dry <br /> or there were obstructions in the wells (pumps) . This <br /> rinformation is still missing from the report text and could <br /> - information <br /> ascertained-°by �readiny tie cra_-n_of_-_ustodv_forms. <br /> Your plots of benzene concentration in water are misleading <br /> for two reasons: (1) Benzene concentration in ground water <br /> is not a 3-dimensional parameter, and (2) The values <br /> assumed for benzene when free product is present are not <br /> accurate (Benzene solubility in water is 1780 mg/1) . Your <br /> own data shows benzene contamination in water in millions of <br /> ppb. <br /> The statement about how you will treat ND values for <br /> computer modeling and graphs is wrong. It either suggests <br /> that an attempt is being made to deliberately present <br /> misleading data, or that whoever is responsible does not <br /> grasp the concept of detection limits.
