The Sorell Council says it will be “extremely difficult” to pinpoint the exact cause of ongoing poor water quality at a section of Primrose Sands Beach.
The boat ramp end of the beach remains off-limits to swimmers as contamination continues to be detected in the area.
High bacterial levels found in early March samples have kept the ‘do not swim’ warning in place, though samples from the shop end of the beach show swimming is safe.
“Initial seepage sample results suggest there is some impact from local septic systems,” the council said.
“While we are unable to identify a clear linkage to a particular system or area, the data suggests seepage impacts are likely to be coming from a number of properties.”
The council is now consulting specialists and urging residents to inspect their onsite septic systems.
“Many properties in the area have older septic systems, which are potentially nearing the end of their useful life,” the council said.
“Property owners should be planning for their replacement to ensure they are meeting their obligations for managing wastewater on their property appropriately and responsibly.”
“This will help improve our water quality.”
