A decision will be made in the next few months that will affect the reputation, the economy and the natural resources of Conway and the Waccamaw River for decades to come: Will Santee Cooper leave arsenic pollution and 1.3 million tons of toxic coal ash in the wetlands of the Waccamaw River in downtown Conway forever? That is the question before SCDHEC, the courts and Santee Cooper itself.

This video is seriously interesting. This is the only kind of cement we should be pouring from now on. Can you imagine how this could lessen the flooding in urban places? Yeah and turn the sound off unless you like listening to safety beeps.
One of the things I’ve learned about concrete made with coal (fly) ash is that it’s more dense than traditional concrete, and less pervious. It’s argued that density is a good thing, and here’s why:
It’s no secret that coal ash is a waste product — it’s what remains after coal is burned to generate electricity. Neither is it a secret that coal ash contains a long list of elements, including some radioactive elements and many heavy metals.
The theory is that if coal ash is less pervious, and those elements remain encapsulated in the concrete, then they can’t leach out and contaminate air (dust) or water (via run-off).
So, while it’s interesting and good that the concrete featured in the above video can absorb water — because it will slow stormwater run-off that negatively impacts waterways, that feature would be a bad thing where concrete made with coal ash is concerned.
