I have Field_ID MW6A_A. I thought this would split into Location_Code MW6A and Well A based on review of the ESdat documentation, but it splits into MW6 and A. I have numerous landfill sites where the A, B are reveresed (i.e., A is deep and B is shallow) for which I wanted to use well codes so the data will sort properly (i.e., A = shallow, B = deep). Is there a way make the split retain the correct Location ID (MW6A).
