Abstract

Water monitoring is essential to ensure safe drinking water for consumers. However existing methods have several drawbacks, particularly with regard to the poor recovery of Cryptosporidium due to the inability to efficiently elute Cryptosporidium oocysts during the established detection process used by water utilities. Thus the development of new inexpensive materials that could be incorporated into the concentration and release stage that would control Cryptosporidium oocysts adhesion would be beneficial. Here we describe improved filter performance following dip-coating of the filters with a "bioactive" polyacrylate. Specifically 69% more oocysts were eluted from the filter which had been coated with a polymer than on the naked filter alone.
