Samples of Baker City water collected on Aug. 28, Sept. 2 and Sept. 3 showed no cryptosporidium in lab tests.

The latest batch of crypto-free water samples included one from Elk Creek, collected on Sept. 3, according to the city.

A water sample taken from Elk Creek on Aug. 4 contained 913 crypto oocysts, making that stream the prime focus for the ongoing investigation to determine the source of the parasite that contaminated the city's water and sickened several hundred people in July and August.

The city has not used Elk Creek water since Aug. 7, the day it received test results from the Aug. 4 sample.
