I own a swimming hole that just happens to be stocked with brook trout. I really enjoy fly fishing for brook trout but jumping in on a hot summer day is just as enjoyable, if not more so.
I have my water tested twice a year, once in late spring and again in the middle of summer. I also use test kits for e.coli and coliforms after substantial rains or before parties. I have never had an issue.
If I was you, just to placate the wife, spend 25$ on a test kit and enjoy the peace of mind.
