            2.4.2      HR Wallingford Testing – Oil & TPH
            Tests were performed by HR Wallingford facility and at HR Wallingford UK with the device in flow mode, with
            the following results. Test methodology was done to European Standard BS EN 858.1 Section 8.3. The results
            are presented below.

            2.4.3      Australian Field Testing – Oil & TPH
            Grab samples have been collected from a number of installations across Australia immediately after rainfall
            events to compare the concentration of hydrocarbons in the inlet chamber to the outlet pipe. The results have
            been collated for Woolworths Bombaderry, Woolworths Lakewood and Woolworths Warner and are presented
            below.

            Flow-weighted, Event Mean Concentration (EMC) field testing has commenced at a Freedom Fuels Station on
            the Gold Coast and only 2 qualifying events have been recorded at present. This information will be released to
            industry once further events have been received and reported on by the independent research organisation.
