Its been some time since I had my well replaced, like maybe 15-20 years ago, I had Patuxent Well do mine, excellent job. I didn't pay for any testing of the water, the St. Marys Health Dept. did my sample. Guess times have changed and people have to pay to have it done now or maybe I did pay, might have been in the total cost of the well from Patuxent. Winslow does excellent work too, some of my neighbors have used them.
