Our options are to 1) Do a 4 hour pump test and re-test the water at the end, hoping the levels would be less, or 2) Hire a water engineer to design a filtration system.
I talked it over with our builder and have opted for the water filtration system. It means a bit more expense up front, but it's a guaranteed fix. It means our water will be filtered, so no arsenic, hard water, or any other water quality issues down the road. Our water will be perfect. Also, if we sell someday, having the filtration systems means no matter how they adjust legal limits for things, our house will be compliant. No re-sale issues.
Luckily our builder just went through this with another family, so he knows who to contact and what to do. He's reaching out to a water engineer to get started on the design. Hoping they can get it ready before our July 16th deadline. If not, we'll submit everything else and ask for a little time to wrap up the filtration plan.
