This study investigated the concentration of amoebic and bacterial populations in eyewash station water relative to various flushing regimens.
Amoebae concentrations averaged approximately 200 amoebae/100 mL in 13 of 15 stations positive for amoebae and consisted of Hartmannella and Acanthamoeba.
Bacterial concentrations ranged from 10° to more than 105 colony forming units per mL.
Amoebic concentrations differed notably between stations located in Buildings X and Y (p<0.0001).
Further study indicated that removal of diffusing screens did not substantially change (p>0.05) the concentration of amoeba.
Amoebic and bacterial concentrations temporarily decreased with the various flushing regiments tested.
Lower amoebic concentrations were not sustained by a weekly 3-minute or a monthly 1-minute flushing regimen.
However, weekly 3-minute flushes appeared to be more effective in maintaining lowered bacterial concentrations (p<0.0001).
