Me, I would have the water tested to make sure it's safe since you're new to the property. Nobody really knows what may be buried on or near the property before you bought it.
@Djcala I really like this suggestion from John.
Let me give you some suggestions from my experience.
In the early '70s [last century!] I was an Engineering Tech for the Sarasota [FL] County Health Department. Our office was responsible for water treatment, delivery, testing, wastewater collection and treatment.
We often did testing of water for residents, restaurants, lodging, agriculture, etc. on request. We preferred to do our own collection because a sample brought into the office in an old mayonnaise jar might not be reliable. We were happy to go to the site and make sure the collection vessel and faucet were sterilized. In the case of running water like streams, sewers, or springs we could do continuous sampling to test for the changing quality over time.
So give your health department a call and describe your situation. They may do anything between Bring Me a Mayo Jar to Dropping a Probe. Most likely they'll start w/ a single sample sent to the lab.
There could be checks for E coli, metals, dissolved oxygen, VOC, industrial waste, etc. Probably free, maybe low charge if it gets complicated.
Another thing... in Sarasota we had access to detailed aquifer maps of the whole state. Our well fields tapped an underground river that ran for a hundred miles. That helped us trace contaminants. Your land sounds like a great place for a field trip. I loved doing assignments like that.
Our office was very encouraging of residents interested in their water quality. We never made them feel like it was a burden on the department. Give that a try.
