Hi all! Would really appreciate some experienced eyes giving my home water treatment plan a once-over. All feedback appreciated.

We bought a rural property and got a lab test for organic and inorganic levels. Organic test came back with some non-e. coli bacteria (which was addressed by shocking the well), but since this is a seasonal property, we wanted the peace of mind of a UV filter.

But the hardness (366ppm/21gpg) and TDS (494ppm/29gpg) are very high and there's enough iron content (0.32ppm) that exceeds what a lot of UV filter manufacturers list as the upper limits of what the filter can handle. Full water tests are below.

One bathroom, 2 adults, 2 kids, standard appliance needs (washing machine, dishwasher).

Water Treatment Plan

Stage 1: 10" Big Blue with a 5 micron sediment filter for turbidity and large particles

Stage 2: Clack WS1 with 10% crosslink resin, 32k grain

Stage 3: Another 10" Big Blue with a 5 micron sediment filter (in case of resin leak when backwashing)

Stage 4: Viqua VH200

(I used AI to take the PDF test results and format the mg/L to gpg conversion. Sorry for any weirdness in how they display.)
