Do you guys drink the 350ppm water? What does it taste like?
As for 70ppm, would you advice against using that for growing?
Often water with a bit higher PPM tastes fine, as the minerals are what give the water a pleasant taste. Drinking water has minerals for the flavor aspect. FWIW, my tap is about 300-350ppm (haven't checked it real recently) or so, and tastes surprisingly good.
If I had 70 ppm water without heavy chloramines I would definitely be happy to use it on my plants...
