I agree, but wanted to ask what part of SWLA are you in? It seems metals are more of a problem in well water from the coastal plains area, and less toward the hillier northern part of SWLA, with Sulphur also being common in the well water in the coastal plains. Also do you know the depth of your well, there are 3 separate aquafer sands overlaying each other in parts of SWLA, with the Chicot being the largest and most commonly tapped, but even it has 3 levels of sands.
