RUMFORD, Maine (WJW) – Residents in the Maine town of Rumsford are being asked to avoid touching or ingesting any "brown" snow that fell over the area this week. The town was treated to the not-so-white snowfall on Tuesday. Local officials have since determined the cause to be a malfunction at a paper mill, explaining that the mill had released a paper-making byproduct called "black liquor" into the area, resulting in "precipitation of brown or tan colored snow," according to a Facebook post from the Town of Rumsford.

It is non-toxic, officials claimed, but still may irritate skin. "We are hopeful the rain tomorrow will wash most of the substance away and flush it off the ground and people's homes or property," town officials said Tuesday.
