Cyanuric acid is used to stabilize free chlorine to reduce photodegradation in outdoor swimming pools. While there have been numerous studies examining its effect on the disinfection rates of bacteria and viruses, it is not known whether cyanuric acid can significantly impact the effectiveness of hyperchlorination for inactivating Cryptosporidium oocysts present in fecally-contaminated swimming pools. This study examined the effect of cyanuric acid on the disinfection rate of Cryptosporidium…

Effect of cyanuric acid on the inactivation of Cryptosporidium parvum under hyperchlorination conditions.

This study demonstrates CYA significantly delays chlorine inactivation of Cryptosporidium oocysts, emphasizing the need for additional pool remediation options following fecal incidents.

Assessing the Impact of Cyanuric Acid on Bather’s Risk of Gastrointestinal Illness at Swimming Pools

Current regulatory codes for swimming pool disinfection separately regulate free chlorine (FC) and cyanuric acid (CYA). It is well-known that CYA affects disinfection rates by reversibly binding to

Limiting swimming pool outbreaks of cryptosporidiosis - the roles of regulations, staff, patrons and research.

Key barriers to limiting swimming pool-associated outbreaks of cryptosporidiosis are a lack of uniform national and international standards, poor adherence and understanding of regulations governing staff and patron behaviour, and low levels of public knowledge and awareness.

Physicochemical and ecotoxicological assessment of the fraction of impurities present in washings obtained in ultrafiltration and nanofiltration

The washings remaining after rinsing the pressure filters in swimming pool facilities constitute a stream representing the full array of impurities found in these waters. To separate individual

Cell Culture Infectivity to Assess Chlorine Disinfection of Cryptosporidium Oocysts in Water.

This chapter provides a detailed protocol to assess disinfection efficacy of chlorine against Cryptosporidium oocysts including the core chlorine disinfection assay, the in vitro cell culture

Enteric pathogens in pool water can be unintentionally ingested during swimming, increasing the risk of Acute Gastrointestinal Illness. Swimmer activities and behaviors influence pool water ingestion

Increased Hepatitis C Virus (HCV) Detection in Women of Childbearing Age and Potential Risk for Vertical Transmission - United States and Kentucky, 2011-2014.

Findings highlight the importance of following current CDC recommendations to identify, counsel, and test persons at risk for HCV infection, including pregnant women, as well as consider developing public health policies for routine HCV testing of pregnant women and expanding current policies for testing and monitoring children born to HCV-infected women.



Pseudomonas aeruginosa for the evaluation of swimming pool chlorination and algicides.

Concentrations of ammonia and the chlorine stabilizer, cyanuric acid, which could be expected in swimming pools decreased the rate of kill by chlorine of the potential pathogen, Pseudomonas

Effects of Isocyanuric Acid on the Poliovirus Inactivation with Hypochlorous Acid.

Isocyanuric acid (H3Cy) has been used in outdoor pools as a chlorine stabilizer. For the evaluation of the influence of H3Cy on the disinfection with chlorine, the inactivation rates for poliovirus

An evaluation of the inhibitory influence of cyanuric acid upon swimming pool disinfection.

An evaluation of the effect of cyanuric acid on the bactericidal properties of chlorine under laboratory conditions at 200 C, approximately the conditions developed by Butterfield, et al, found that at a pH of 7.0, the time required to effect a 99 per cent kill was 0.5 minutes.

Inactivation of Naegleria gruberi cysts by chlorinated cyanurates

The results strongly suggest that HOCl is the predominant cysticide with no measurable cysticidal effect of the chlorinated cyanurate species.

Effects of ozone, chlorine dioxide, chlorine, and monochloramine on Cryptosporidium parvum oocyst viability

The data indicate that C. parvum oocysts are 30 times moreresistant to ozone and 14 times more resistant to chlorine dioxide than Giardia cysts exposed to these disinfectants under the same conditions.

Influence of Stabilizer Concentration on Effectiveness of Chlorine as an Algicide

The toxicity of free chlorine to three swimming pool algae was reduced slightly by 25 mg of cyanuric acid per liter if inhibiting, but less than algicidal, concentrations of chlorine were employed.

Improved Purification Methods for Calf‐Derived Cryptosporidium parvum Oocysts Using Discontinuous Sucrose and Cesium Chloride Gradients

A number of improvements in the production and purification process for calf-derived oocysts are introduced to minimize labor, consumption of materials, and generation of hazardous waste.

Surveillance for waterborne-disease outbreaks associated with recreational water--United States, 2001-2002.

The number of recreational water-associated outbreaks has increased significantly during this period and could reflect improved surveillance and reporting at the local and state level, a true increase in the number of WBDOs, or a combination of these factors.
