DNAPL (Dense Non-Aqueous Phase Liquid) FOUND AGAIN AT CHEMTURA

I am slowly beginning to realize that one of the tactics used by polluters and their consultants is the simple tactic of deflection. For example rather than discussing, debating or arguing how to remove DNAPL from their Elmira property they are instead arguing over what form the DNAPL is in. Is it Free Phase, as in pools of collected heavier than water liquid, or is it Residual which means it is in much smaller ganglia or filaments in the pore spaces between soil particles? To a certain degree these arguments are irrelevant. Both forms of DNAPL cause longlasting groundwater pollution although the Free Phase generally indicates larger, longerlasting volumes.

Free Phase agreed/admitted to has been found on both sides of the Canagagiue Creek running through Chemtura's (Uniroyal) site. It has been found in M2, TPW2, RPW5 on the west side and near RPE2 (OW148) on the east side. When I say found I mean as in physically and visually captured and contained, for example in a sample bottle. Chemtura's consultants (CRA) again in last month's Progress Report, partially discussed yesterday here in the Advocate, reiterate their inflammatory and quite frankly stupid use of the terms direct and indirect evidence. This ridiculous definition, most probably invented by themselves has long been disagreed with by the old CPAC and other citizens. Table D.1 has a very long list of DNAPL chemicals found in the groundwater at well OW10. Some of these chemical concentrations are above the 1% solubility rule indicating the presence of nearby DNAPL. The sheer number of DNAPL chemicals is of huge significance as has been submitted to CPAC in the past by both myself and the former Soil & Water sub-committee of CPAC.

Hence this section in the November Progress Report (Pg. 6 & 7 + Appendix D) is merely one more in a decades long history of reports DIRECTLY proving the existence of DNAPL, both Free Phase and Residual on the Chemtura site. Stop the semantics and bull and start removing it.
