I still reckon there'd be dust in general when the air is cold and humidity non-existent and/or salt spray from the street. But it should be lower than close to the street and higher than the backyard. Just guesses though. I live downtown so we're right on the sidewalk. Another storm is due soon so I may be able to test sooner rather than later...

How about snow from the middle of an undisturbed lawn? That should be pretty much TDS=0 right? I thought the same as you (see quote) but no matter how I tried to get "good snow" the TDS was disappointingly high.

That makes sense that snow would be "dirtier" than rain because it falls slower and it has a far greater surface area. Still I couldn't imagen that the difference would be that large, far less then Toronto's ~150 ppm water.

We're supposed to get 30 cm. I'll try and check the TDS.

I caught some snow/freezing rain in the front yard last night right into a tray. TDS 25. A bit high.
I just collected some snow-ice from the back yard. TDS=0 PPM. Pretty good.
I guess the lesson is snow is good but you have to check it.

Thanks for taking those readings Lloyd, as I expected. I'll try to check mine tonight.
