Not saying I didn’t believe it could be done. Just can’t believe what needs to be done to keep the streets safe.
Not true, a lot of cities still have lead pipes & are slowly replacing them. They are adding orthophosphate to the water to create a protective layer in the pipes to stop the lead from getting in the water. Flint, Michigan is the place that got all the news stories but a lot of other cities have similar lead issues. Also reading a lot of articles lately about wastewater.
