"For Pittsburghers trying to guard their tap water from lead, the price can be steep.
Excavating and replacing a privately owned lead service line — the water connection into a house — can cost some $4,500, according to the Pittsburgh Water and Sewer Authority. The price may vary by thousands from property to property.
But an emerging technology could coat the insides of those pipes instead, a process shown elsewhere to prevent lead contamination for much less expense and disruption, authority spokesman Will Pickering said Wednesday. Under a pilot agreement with PWSA, a West Coast company is employing the approach at six Hill District homes to show its effectiveness here."
