Positives are currently present on both <br/>pre + post flush samples. Areas that are currently unoccupied are showing more positives then the <br/>areas that are in use.<br/> Site would like to implement the localised disinfection + repair of incorrectly repaired markwik 21(+) <br/>taps to standard operating procedure, estimate counts 600+ outlets require investigating/repair.<br/> Site would like to implement a more regimented and documented flushing regime of the 900-1000+ <br/>outlets on site. Consider using chlorine dioxide profile tests to determine the flushing time required <br/>on outlets and to aid with systemic disinfection. Random outlet tests yesterday showed that chlorine <br/>dioxide levels were varied and in some cases almost non-existent and took considerable time to <br/>bring through to stabilised Cl02 standard levels at the outlets (0.1 - 0.5mg/l).<br/> Current chlorine dioxide unit on site appears to be ‘slug dosing’ instead of stabilised dosing leading <br/>to fluctuations in chlorine dioxide levels at outlets.
