Evaluation of the ICR protozoan method and Method 1623 for detecting Giardia and Cryptosporidium in actual water samples
Keyword(s):
Giardia and Cryptosporidium have emerged as waterborne pathogens of concern. This study examined both parasites in actual water samples, which were taken from Cheng-Ching Lake waterworks in southern Taiwan. The Method 1623 was characterized by a higher recovery rate and lower detection limit compared with the ICR protozoan method. It was discovered that water turbidity reduced the recovery efficiencies, and raised the detection limits for both parasites, regardless of the method used. The concentrations of both parasites showed inconsistency for different recovery rates and detection limits between the two methods. A significant correlation between water turbidity and Cryptosporidium oocysts in raw water samples were found in this study.
