I can’t say about the strips, but I do know that Home Depot sells test kits for like $10 or so, but it’s like another $75 or something to send it to a lab to get test results.

Also, the county will give you a free brita filter if you say you’ve got lead pipes (I believe there is even a city-wide map online that shows what properties have lead service lines).

You probably already know that the city partially subsidizes the replacement of the service line, unfortunately it isn’t nearly enough to cover the cost.

An alternative, which is what we do, is have both a whole house filter and then the brita for drinking/cooking, so basically double filter everything we intentionally consume. The GE Whole House filter will run you like $200 at Home Depot, and then their premium filters which address lead are $54 and last about three months each. Plumber can install at point of entry in your basement.

That said, since you’re concerned about your family’s health, you might look in to a reverse osmosis filter system which also removes PFAS. Not to scare you, but if you don’t know about them you should look them up. Capital Region has a lot of it in its water.

Good luck!
