Samples cause for concern
In response to the Minister for Water, WA Water Corporation and the mayor (Coastal pollution fears dismissed, 31/10).
Firstly, I want to point out that the sample mentioned had a threshold upper limit set for the licence at 15.
It came in at 18,000 with several others at 8000 to 14,000; 41 per cent of offshore samples exceeded the threshold and 26 per cent of shoreline samples exceeded their limit.
So the government bodies say that these occurrences of discharges above the licence set threshold dilute and pose no health problems?
Why then do the onshore sampling points between Point Peron and Long Point show levels well above the threshold levels taken at the same time?
The same annual reports show similar trends taken from outlets north of Perth at Swanbourne and Ocean Reef that may be news for beachgoers in those areas.
There are no sampling points for the Point Peron waste-water treatment plant on the Rockingham side of the causeway.
Dr Steve Capewell said these samples are expected to be high on occasion.
Well the public think differently, we were sold on the premise and environmental licence that the sewerage was treated before being discharged.
This is now 2018 and parameters set in the 1985 environmental licence are well and truly below public’s expectations today.
