Effect of rainfall on Giardia and crypto
Rainfall increases concentrations of Giardia and Cryptosporidium through its influence on turbidity, flow volume, and possibly other unidentified factors.An investigation of the variability of concentrations ofGiardiacysts andCryptosporidiumoocysts in the Delaware River was conducted in 1996 at Trenton, N.J. A goal of the study was to examine the relationship between concentrations ofGiardiaandCryptosporidiumand a variety of more easily measured microbial, water quality, and meteorological parameters. A positive correlation (Spearman rank;p< 0.05) was demonstrated between concentrations ofGiardiacysts orCryptosporidiumoocysts and 15 other parameters. Increased concentrations ofGiardiaandCryptosporidiumas well as a variety of other microorganisms were associated with rainfall. The effect of rainfall on parasite concentrations is due in part to increased particulate matter in the water column following surface runoff and resuspension of river bottom and storm drain sediment.
