Officials Monitor Scioto River For Parasite

COLUMBUS, Ohio (AP) - Officials in Columbus are monitoring rising levels of a chlorine-resistant parasite in the Scioto River near wastewater treatment plants.

Tests at the treatment plants and two areas of the river south of Columbus this week showed a rising level of cryptosporidium, which can cause severe intestinal disorder.

Officials say the city's drinking water is safe and reservoirs are not affected.

Residents are advised to avoid swimming in the river and to wash well with soap and water in case of direct contact with the river.

Columbus and Franklin County have reported 179 cases of crypto illnesses already this year, compared with 27 in 2007.
