A recent discovery in a June 1994 report written by Associated Engineering for the Region of Waterloo has been posted on the Cambridge Advocate website. Essentially my worst fears appear to have come true as Table 1 in Appendix C lists detections of over 100 chemicals in well P11 (Preston 11). The significance is that this Table lists a couple of hundred different organic chemicals versus the usual fifty or sixty for example that the Region of Waterloo Annual Reports (water) list . Secondly the MDL (method detection limits) are approximately a thousand times smaller in this June 1994 report than again for example the Region's Annual Reports. Therefore as I have long feared, there may probably be dozens of chemical contaminants in our drinking wells whose presence is easily masked via high detection limits as well as by "cherry picking" which chemicals are to be listed and hence ignoring more likely candidates for detection.
