220 ppm. Thats nuts and dirty water. That is what I would guess is creating this white foam buildup. The local water authourities put chemicals in our tap water so that contaminants don't make us sick. Yeah like putting chemicals in drinking water helps. Anyway, your water source is the reason for your prob. Oh yeah, plants can grow in dirty water but don't expect any flowers.

My suggestion would be for you to get yourself a RO filter installed in your kitchen. Or if you can do it yourself, install it where you please. You can never go wrong with RO, 15 - 30 ppm max!
