I don't recall Joel ever tweeting that his sample results were submitted, and he was waiting on ADEQ to review them. I do remember him saying he was going to collect samples.
Did he ever do it? Based on his current status with ADEQ, I would say no (see below - status is shown as "overdue" and the timeframe is "expired"):
Even if he did collect samples, ADEQ would reject them. Samples have to be collected by a registered, third-party geologist or engineer.
