Impact/Purpose:
1) Refine new, practical methods for the detection of CCL-related and emerging waterborne human protozoa.
2) Perform field tests of devices or methods that have been developed under this task.
3) Evaluate these methods or devices in a variety of water matrices and parasite concentrations.
This work in this task supports CCL2 and 3 and is expected to be completed by 9/07.
Description:
Protozoan parasites including Giardia, Cryptosporidium, and Entamoeba can be transmitted through water and cause disease in humans and animals. Control of waterborne infection can be accomplished through a variety of physical and chemical means, resulting in the production of safe drinking water and protection of public health. Coagulation, sedimentation, and filtration are the most commonly employed methods for physical removal of parasites, while chlorine-based compounds, ozone, and ultraviolet light are used for inactivation. Combinations of treatment technologies can result in parasite removal/inactivation greater than 6-log (10) resulting in reliable public health protection
