The chemical found in Seattle and Spokane was Clopyralid from lawn weed
killer. At that time it was a favorite chemical for lawn care companies and
was even in some weed and feeds.
Picloram has also been found in compost that used straw where the field had
been sprayed with Tordon but that only showed up in towns next to large
farms.
The contaminated compost could be used on lawns but if it was put in a
garden it would be three years before a tomato plant would live in the soil.
(If you wanted to grow tomatoes on ground that has chemicals in it.)

Our citys compost at one time was contaminated by chemicals some
homeowners use on their yard. It killed some plants it was used on.

Ya know i could see that happening!

But how did it get into the compost (enough to cause damage) if they are
just putting in clipping and such? And where do you live?

It was one herbicide that just didn't biodegrade, that was effective at
very low doses.

You don't know the name of the chemical do you?
