Portland approves water filtration plant to treat for parasite
PORTLAND, Ore. —
Portland's City Council has voted unanimously to pursue building a water filtration plant to treat drinking water from Bull Run.
That's the most expensive option available to treat water from the mountain reservoir -- some estimates top $500 million.
At issue is several recent water tests found a parasite called cryptosporidium.
Federal regulations require water treatment after that many positive tests.
Almost a million people in the metro area get their water from Bull Run.
