PORTLAND, Ore. (AP) -- A parasite found in two water samples could affect Portland's effort to avoid building a $90 million treatment plant for the Bull Run watershed.

Tests found the cryptosporidium parasite in Dec. 30 tests.

The Portland Water bureau told The Oregonian (http://is.gd/hM3cjZ ) there is no imminent health risk and it shouldn't affect the decision that an ultraviolet plant is unnecessary.

The Oregon Health Authority's Public Health Division said in November it probably would give Portland a variance. The state has until Jan. 31 to make a final decision.
