Hi... @jk thanks for info yes didnt know who was behind the web site, so its to obtain business in the water industry... i usually check source of web sites... but on way out door to dentist yesterday ... long story short years ago we lived where daugher is now, old cottage, and water issues right from day one with well... anyway quite a few calls with government agency and one day he said, you can test the water one day and 2 days later will be a problem, 2 days later ok..... i thought, well, we're sunk then! But this cottage/house on a slope to lake so who knows what liquids were running through the soil...even if we are/were 100 per cent on top of having water tested etc., what's to say we visit someone with a well, or even a restaurant or such that has a well, we how no clue as to whether or not they have water checked. Even our municipal water has chemicals added and now zinc.. why zinc.. to protect the pipes!! We live 2 blocks from the water treatment plant and i always feel that the closer we are to the chemicals, the closer we are to the chemicals... and apparently its true. But not much choice unless we get a rain barrel! i am not a "tree hugger" but seems we humans are causing so many problems for ourselves these days. J.
