The HHE Program responded to a request for assistance at an indoor water park. The request concerned the cause of symptoms involving irritation to the eyes, nose, skin, and respiratory system. HHE Program investigators tested the air for trichloramines, soluble chlorine compounds, and endotoxins. Investigators tested the water for fecal contamination, Legionella, mycobacteria, endotoxin, sulfites, and sulfates. Additionally, investigators reviewed the ventilation system and water system designs. HHE Program investigators found that some trichloramine concentrations were at levels previously reported to cause mucous membrane irritation and that air endotoxin concentrations were at levels that have been associated with cough and fever. Investigators recommended that managers assess the ventilation system to ensure adequate air movement and proper removal of contaminants. Investigators also recommended that managers consider reducing water attraction cycle times and use larger droplet discharge nozzles to reduce aerosolization of contaminants. Investigators recommended that managers consider redesigning the spray feature piping system to make sure that water used in the pools is taken directly after the filtration and treatment cycles. Additionally, investigators recommended that employees report any work-related symptoms to their supervisors.
