There is no safe level of lead in drinking water, but a zero goal, though laudable, is at present an unattainable goal. The policing of lead in drinking water is generally in the hands of the local utility company until testing reveals lead levels higher than 15 ppb (parts per billion) in 10% of the samples collected in the distribution system.
