So we’ve received our heavy metal analysis. This was done by testing the water that flows in to the dam, which comes from the quarry. This is important since there is alumn shale (black shale) below the lime stone which can harbour all sorts of nasty elements such as uranium and other metals. We wanted to test the water to make sure that none of this was leaking out into the dam, and then further out to the wetlands. Heavy metals in the water would be devastating for the flora, the fauna, and the ground water. We didn’t expect there to be any elevated concentrations, which was confirmed by the test (i.e the water is clean enough). Cementa stop mining the lime stone well above where the shale begin so there shouldn’t be any leakage, but it’s always good to double check!
