Some water service lines in Flint were installed between 1901 and 1920. As with many other municipalities at the time, all of the service lines from the cast iron water mains to end users' homes were constructed of lead, because it was relatively inexpensive and easy to work. Lead pipes can leach lead into the water, especially if certain contaminants are present. However, the water from the Detroit Water and Sewerage Department, where Flint had obtained its water since 1967, had been treated well enough that the leaching from the lead pipes was at levels considered acceptable by state and federal environmental protection agencies. There are an estimated 43,000 service lines in the city; these include 3,500 lead lines, 9,000 known galvanized lines, and 9,000 unknown service lines.
После этого, наш водопровод из железа и вода из артезианских скважин (в нашем городе, во всяком случае) кажется, просто эталоном полезности.
