I have just received an E-mail from Mr Chris Munroe who i again called this week below is a copy of the E-mail he sent me.

Dear Thomas,Many Thanks for your email about stormwater pollution at Redleaf Pool. I have checked our Drainage Maps and there does not appear to be any direct stormwater drains flowing into Redleaf Pool. I have attached a map below which shows the drainage lines in Blue. There is however a Stormwater Drainage outlet on Seven Shillings Beach. This drain collects all the runoff from New South Head Road and Victoria Road, and would be the most likely point source of pollutants There is also a stromwater drain on the western side of Redleaf Beach. I'm pretty sure this pipe only releases localised stormwater flows from the Council Chambers, and the Council Carpark. Stormwater runoff collects a range of land based pollutants as it makes its way to the receiving waters. Pollution sources include:
Litter from general sources;
Sediments and suspended solids from construction sites, and poorly landscaped areas,
oils, surfactants, heavy metals and other road pollutants,
organic matter such as leaves and twigs from gardens and street trees,
nutrients from fertilisers and detergents,
faecal coliforms from animal faces. and sewage overflows
toxic materials from accidental spills Habourwatch water quality The EPA measures the recreational water quality of Sydney Harbour and the surrounding beaches through the Horbourwatch and Beach watch programs. These programs involve the routine monitoring and reporting of Bacterial levels (Faecal coliforms and Entercocci) to determine water quality at recreational swimming locations. Please see the link below for the latest results for Redleaf pool:

The state of the Beaches Report 2006-2007 is posted on the link above and provides information on water quality in Sydney Harbour's swimming beaches.

Unfortunately due to my e-mail site i have been unable to veiw the attachment of the map he sent me as such i will have to continue my MDC as befre and again contact Mr Munroe.
