This is less than the allowable level in most states whose standards are based on the Federal Safe Drinking Water Act, which has been very effective in making drinking water safer.

The Act is administered on a state-by-state basis.
ADJUSTABLE HOT LIMIT STOP: Restricts hot water output in single control faucets and showers to protect against scalding by limiting the swing to the hot side.
