Coincidence perhaps, but there is a context of which experts in the field ought to by now be aware, that remains unimplied, at least in the following report, and undermines the findings:
Technicians [from CEMRC] ...took samples on March 20 and March 28 from Brantley Lake and Red Bluff Lake, according to the release. Samples were collected from shallow and deep water areas. ...Sediment samples from the reservoirs were also collected, however CEMRC is still analyzing the samples and will release the data reports some time in the future.
Perhaps we ought to hold our breath while they get back to us? Perhaps not. Here's why, with proof.
