The saga of why my well has gone wonky and what’s to be done about it continues.
I’ve learned a few new things over the last couple of days though. Or instance, the homestead sits on three distinct layers of sand/gravel, sand/clay, and sand. The well goes 195 feet down through them to the final sand layer. That’s not overly surprising. If I remember my long-ago undergraduate geography class, the whole of the Eastern Shore is a sand berm pushed up at the end of the last ice age by the proto-Susquehanna River as the ice melted.
Knowing that, having a bit of extra sediment coming through is fairly easily explained – by someone who knows more about hydraulics than I do. The most likely cause, according to the well company, is a slight shift in how water is flowing through the aquifer coupled with a 20-year buildup of sediment in the bottom of the well. The proposed solution: Raise the depth of the pump a bit. Sounds reasonable to me.
The bug and bug part intrusion, remains more of a mystery. They’re not exactly naturally occurring at depth in the water table. There’s no evidence of bugs making their way through the well cap, either. The tentative recommendation there is swapping out my current single-stage filter to a two- or three-stage set up that should capture everything down to the one-micron level. Not much should make it through that – certainly nothing large enough to identify definitively as a “bug part.”
The company I’m dealing with still wants to do a bit of homework and wait for the results of the water tests to come back, so we’re not at a point where we have a definitive plan of attack or a projected butcher’s bill for getting it done. Not that it matters all that much. It’s not like I’m going to opt to keep the bugs, regardless of the price put on making the fix.
