Hmm. When you hear about E. coli outbreaks in vegetables, it's traced back to fecal contamination on the worker's or processing equipment's working surfaces.
I looked to find any sources with high quality scientific evidence showing accumulation of toxic waste in timber roads in WA. I am an open minded scientist, if you post high quality work I'll read it and change my mind.
"There are three general methods for applying biosolids to forests: 1) spray irrigation with either a set system or a traveling gun, 2) spray application by an application vehicle with a spray cannon, and 3) application by a throw-spreader or manure-type spreader. In the Pacific Northwest, the most common methods for forest applications are the throw-spreader or a vehicle-mounted cannon. Table 7.7 lists these application methods, their range, relative costs, advantages and disadvantages, and their suitability for biosolids of different solids contents."
