For sure. So the impermeable layer the water table is sitting on is actually limestone. The water is stupid hard. But the chance of heavy metal intrusion is next to nil, unless there’s an industrial accident upstream of the material aquifer flow. Not all regions of the US fall into this category but the vast Midwest mainly does. If you’re in an area with non sedimentary bedrock, or in an area where the impermeable layers are penetrated (like mining). My father, also a hydrologist…. Heard non stop about rocks since I was a kid :)
