The biological trump rule in action:
Aquatic insect communities in an area downstream from the Feb. 2 coal ash spill appear to be thriving, according to the results of testing conducted by state environmental officials.
Using a standard sampling protocol, state scientists collected samples of benthic macroinvertebrate at two locations – one upstream and one downstream of the site of Dan River spill. During the sampling, scientists collect insects and other invertebrates from the river using nets and then record the number and species present in their samples before returning the insects to the river. Scientists can determine much about the health of the river based on the number and type of living species they collect. The populations from the upstream and downstream sites were similar and were considered “Excellent,” which is the highest biological rating available.
This is good news, for one location out of a 70 mile stretch of river, that is. Some of that spilled coal ash is now buried under a few feet of silt, but some of it isn't. I won't go as far as to imply DENR testers located a healthy spot and tested that one, although that wouldn't surprise me. But one sample out of seventy miles doesn't a clean river make. Admittedly, I'm a little out of my depth here, but these folks aren't:
