The compost had been made with an herbicide-tainted hay stock that had been labeled as organic. This was one component of many in these tons and tons of compost, which were sold to garden supply centers, and they in turn mixed that compost into their own diluted mixtures.
Everyone in our local gardening groups who bought that tainted compost, their gardens are ruined. I don't just mean for this season. I mean they have to dig out the garden beds, and either find some isolated corner to dump the tainted soil or pay to have it hauled away. Picture after picture after picture of stunted, blighty, yellow-brown, crumpled plants. Large swaths of bare ground with nothing growing but a few weeds. The owners desperate to find out what is happening. I've probably seen that dozens of times this year.
There was a press release where the guilty party in conjunction with the ag board stated that the tainted soil could be composted for two years with some additives to neutralize the herbicide, then they could test for traces of it and the soil should be OK.
So if you have a few years to let this compost somewhere, maybe you'll be OK.
