I would like an answer to that one too. Please copy me in on replies.
And please see my separate post about EA’s & SEPA’s regulatory position on using cementations pfa grouts to infill abandoned mine workings, and the effects, if any, on aquifers.
And, I’m sure you all know that from the 1 April 2010 the EA now have new aquifer designations: Principal Aquifers, Secondary Aquifers & Unproductive Strata.
Have SEPA followed / adopted the same by any chance???
Thanks, Martin
