107-188) and lead reduction provisions as amended by P.L. 111-380 (including amendments made by P.L. 113-64 to explicitly exempt fire hydrants from coverage under the act’s lead plumbing restrictions). Blood alcohol content/concentration (BAC) is a measurement of alcohol intoxication used for legal or medical purposes. A BAC of 0.10 (0.10% or one tenth of one percent) means that there are 0.10 g of alcohol for every 100 ml of blood which is the same as 21.7 mmol/l.
