Chlorine disinfection of recreational water for Cryptosporidium parvum.
We examined the effects of chlorine on oocyst viability, under the conditions of controlled pH and elevated calcium concentrations required for most community swimming pools. We found that fecal material may alter the Ct values (chlorine concentration in mg/L, multiplied by time in minutes) needed to disinfect swimming pools or other recreational water for Cryptosporidium parvum.
متن کاملInactivation of Cryptosporidium parvum under chlorinated recreational water conditions.
Cryptosporidium is a chlorine-resistant protozoan parasite and the etiological agent in many disinfected recreational water outbreaks. While previous studies have reported disinfection Ct values for Cryptosporidium parvum using sodium hypochlorite, these studies have employed conditions and procedures which are not ideal for establishing public health remediation recommendations for chlorinated...

متن کاملDisposable swim diaper retention of Cryptosporidium-sized particles on human subjects in a recreational water setting.
Cryptosporidium is a chlorine-resistant protozoan parasite responsible for the majority of waterborne disease outbreaks in recreational water venues in the USA. Swim diapers are commonly used by diaper-aged children participating in aquatic activities. This research was intended to evaluate disposable swim diapers for retaining 5-μm diameter polystyrene microspheres, which were used as non-infe...
متن کاملTaking the plunge: recreational water quality guidelines.
During the 1980s, the profile of recreational water quality at Sydney’s beaches caused concern among Sydneysiders. Monitoring of recreational water quality indicated that most Sydney beaches had poor water quality, and this condition was attributed to the disposal of partiallytreated sewage at cliff-face discharges. An epidemiological study conducted in 1989–1990 attempted to determine the prev...
