On: AT&T does not intend to immediately remove lead cables from Lake Tahoe

What is the mechanism of exposure?

Well Lake Tahoe supplies the drinking water to much of Northern Nevada and Northern California. If the lead is improperly shielded or shielding has eroded then it's a pretty straightforward journey from there.

Except drinking water (and lake tahoe water) is regularly tested.

The dog that isn't barking is the lead level results of these tests.

Ask the Flint residents.

Tests results depend on the test procedure.

Lake Tahoe holds a truly massive amount of water. 37 trillion gallons of water. Mercury and arsenic contamination from all the abandon mines is a much bigger issue, and that isn't even a real risk to drinking water. (I get my water from the Truckee river)

Is there no lead in the rock on which the lake sits? (i have no idea how to look that up)
