The upcoming Fluoridation plebiscite (Oct.25/10) will be on the ballot in Waterloo, Elmira and St. Jacobs. Here is a website you probably want to see. www.waterloowatch.ca Among other issues I have with intentionally putting HFSA (Hydrofluorsilic acid sp?) in our drinking water, is the number of exceedances year in and year out. Whether this is straight human error or systemic problems with the equipment, pumps etc. , I do not know. There were exceedances (> 1.5 mg/l) in 2004, 2005, 2006, 2007 and 2009. This information is in either the Region of Waterloo Annual Reports (drinking water) online or in their Summary Report (also online under Annual Report)
