How do I find out where my leach field is?
I'm assuming that those of you who looked at my subject line had to open this to see who could possibly be this dumb... BUT We recently (~1 year ago) moved into a house (built in 1967) on 1.5 acres with a septic system. The septic tank is original and is about 6 feet below ground(we had it pumped and inspected last fall), so I'm assuming the leach field must be quite deep down (the house is not on any sort of appreciable slope), but I have no idea exactly how deep or how far behind the house into the pasture it extends. There was no evidence of a gravel layer at about 24 inches down in the pasture when we dug holes for new fence posts.
I'm asking if there's any way to know because I would like to plant my pumpkin patch and potager about 75 feet from the back of the house but I don't want to plant on top of the leach field ( I hear that's a no-no).
Any ideas? Thanks.
