Wow Jay - love the story about the Nova Scotia well
and very good point about the fracking, it really impacts the watersheds it touches... and about the phytoremediation with the area plants benefitting the water quality.
Hey Melissa - sounds like you have some thankfully benign surroundings with organic farms and homesteads and fallow fields. Hope the water test reflects that.
And regarding well depth - more shallow wells for sure have higher risk of contamination than deeper wells due to the natural filtration capacities of rock and soil....
but that risk does not drop markedly until the well is much deeper (50ft- 100ft), and even then very dependent on the local hydrology.
We can proactively balance the realities of that with the really good filtration possibilities that are available now.
The property that I steward is off grid, and I don't have a well - my water source is rainwater catchment (and I am setting up dew capture devices this month - woo hoo).
I use a filter that does not require electricity:

There are probably plenty of other really good filters that others here on Permies are using and can suggest.
Filtration is going to be part of the water plan no matter what... so even if there are contaminants, there are ways forward.
Let us know how the test results come out.
