Note that the half-mile statistic is connected to underwater cables, not buried cables. It is certainly an overcount, but it is probably not trivial to assess the local hydrology and the extent to which children’s play areas might be exposed to such water.

Especially since there are thousands and thousands of schools in America that get their water from wells.

It doesn't seem overly-cautious to wonder about lead placed under a water course 50 years to a century ago finding its way into the groundwater supply a half-mile away.

Hopefully that wondering would lead to testing the water to see whether there is actually a problem.

At that point wouldn't it be so diluted that it's basically indistinguishable from background levels?
