I live with my mom. She has an old well, with a rotting lid. It's about 5 feet in diameter. I didnt want a deer falling through the lid, so I stacked some plywood on top. I checked between the wood, and it is crawling with bugs. Im sure some made it into the well. Im afraid its contaminating the water table, or something. My moms not interested in doing anything about it. I was gonna have it abandoned, but it was too expensive. I dont want a bunch of bugs in the well water, so I was gonna take it all off, exposing the old lid, and then build a fence around it so large animals couldn't walk on it. Should I leave it like it is, and let the bugs fester, or take all the plywood off, and build fhe fence around it until I can make enough to get it abandoned? Im and idiot when it comes to construction, and stuff, so im not sure what to do.
