Mark, a certain former NSMBA Director now lives and works in Rossland and knows a lot about the lead impacts from the smelter in Trial. There are definitely concerns over metals, such as lead in soil, particularly for kids, in certain, but not all areas of Trail.
I'm sure he could clue you in. If you don't already know him or how to contact him let me know and I will PM you details.
Please let me demonstrate the ride around; really it's no trouble.
