And, most of the affected pipes are inside the family home. Old galvanized pipes and in rare cases, even older lead pipes. These old lead pipes get a patina on them that shields the water from the lead. Galvanized pipe has trace amounts of lead. Even brass fittings have trace amounts of lead. Just last year a new law was passed. Fittings and pipe must be lead free. 0%. As you can imagine, the cost went up about 60% to 70%.
The river water was more acidic than the old water supply and is now leaching lead from the pipes and fittings.
My point is that homeowners are responsible for their own house and its maintenance. The State is responsible for the distribution system. While the State does bear some responsibility, I don't think they should be responsible for replacing ALL the pipes in EVERYONE'S home.
Slight correction. The CITY is responsible for the distribution piping. The CITY is also responsible for monitoring and adjusting the water chemistry. See 40CFR141.80
