FREE GROUNDWATER TUTORIAL

This is a link to a fabulous report titled "Review of the State of Knowledge for the Waterloo and Paris/Galt Moraines". This report explains how the geology in Kitchener-Waterloo, Cambridge and Guelph was formed. It explains simply and clearly how groundwater is stored, recharged and discharged. There is a separate link to the Figures which are also excellent. Click on "The Report figures are available as a separate file 17 MB." I especially recommend for study the following half dozen figures: 3.2.1 , 3.2.2 , 3.2.3 , 3.3.6 , 5.3.1 , 5.3.2 .

The text of this report (ie. the 1st link) was an eye opener to me. Even after twenty years of study I learned that groundwater in very coarse gravel can travel up to 100 metres per day. This compares to literature I've read and what we've been told at CPAC, namely that even in gravel, groundwater might travel up to 150 metres IN A YEAR! Although I've known for years that the information we've been sold by Chemtura's consultants and the M.O.E. regarding "impermeable" clay aquitards is nonsense, nevertheless knowing that water can flow through aquitards at a centimetre a day or less is of value. Over a year groundwater can therefore penetrate approximately ten feet through an aquitard. This is the kind of data that should have been made available to all old and new CPAC members years ago.
