Zusammenfassung:This study examines concentrations of Giardia and Cryptosporidium, turbidity, and particles in raw and filtered waters as indicators of treatment plant efficiency. Results indicate that the probability of detecting cysts and oocysts in finished water supplies depends on the number of organisms in the raw water. Particle counts are useful indicators of plant performance and can indicate when filters are not functioning properly. Este estudio examina las concentraciones de Giardia, Cryptosporidium, turbidez, y las partículas en aguas naturales y tratadas como indicadores de la eficiencia de la planta de tratamiento. Los resultados indican que la probabilidad de detectar cistos y oocistos en los suministros de aguas tratadas dependen del número de organismos en el agua natural. Los conteos de partículas son indicadores importantes del comportamiento de la planta y pueden indicar cuando los filtros no están funcionando apropiadamente.
