Probably not top of mind for you, but do you ever wonder: Where does the waste end up that I flush down my toilet?
It’s an important question to some, especially Eastern Washington residents who live near imported post-treatment “biosolids” and who voice concern about King County compost heading their way.
After treatment and drying, biosolids range from sandy material to spongy dirt clods that, though musty and dank, smell nothing like sewage.
Many farmers welcome biosolids, which fertilize and enrich their fields. The owner of a Sunnyside fertilizer company said that after spreading biosolids on hop fields, productivity improved and earthworms returned to the soil.
Yet others call the waste product “sewage sludge” and claim it bears industrial toxins that kill wildlife.
An Ellensburg legislator supports a bill requiring cities to keep at least some of their biosolids on their own land.
Currently, a company approved by the state Dept. of Ecology is applying treated biosolids to an Eastern Washington area the size of Los Angeles. Read the Yakima Herald-Republic article.
