Northern Beaches

Water Quality during May 2011

The water quality at Sydney's northern ocean beaches was excellent during May, with all 21 swimming sites suitable for swimming on all sampling occasions. The sites were:

 Ocean beaches: Palm, Whale, Avalon, Bilgola, Newport, Bungan, Mona Vale, Warriewood, Turimetta, North , Collaroy, Long Reef, , North , South Curl Curl, Freshwater, Queenscliff, North Steyne, South Steyne and Shelly (Manly), and  Lagoon: Birdwood Park (Narrabeen Lagoon)

The rainfall during May was 136 mm, which is just above the long term average of 121 mm. The heaviest rainfall was recorded between 30 and 31 May and triggered a wet weather bypass of secondary biological treatment at Warriewood Sewage Treatment Plant.

On 7 May, a dry weather sewage overflow in Goodwin Street at Narrabeen entered Narrabeen Lagoon and resulted in elevated bacterial levels near Wheeler Park.

Beachwatch recommends that swimming be avoided for one day after heavy rainfall at ocean beaches and for up to three days after rainfall at harbour beaches.

Before heading to the beach, particularly after it has been raining, check pollution levels by phoning the Beachwatch telephone information line on Freecall 1800 036 677 or check the Beachwatch website at www.environment.nsw.gov.au/beach.

When at the beach, look for signs of stormwater pollution such as discoloured water, or litter in the water or on the tide line before entering the water.

Note: Northern Sydney estuarine swimming locations are sampled once each month outside of the swimming season. The enterococci levels in the samples collected during May were below 40 cfu/100 mL at all 14 sampling sites in and North Harbour.

 Ocean beaches: Bondi, Tamarama, Bronte, Clovelly, Maroubra, Malabar and Little Bay Beach.

Enterococci levels exceeded the safe swimming limit of 40 cfu/100 mL on 17 May at Coogee Beach (206 cfu/100mL).

The rainfall during May was 136 mm, which is just above the long term average of 121 mm. The heaviest rainfall was recorded between 30 and 31 May, and triggered a number of wet weather overflows into the and .

On 1 May, a dry weather sewage overflow in Bronte Road entered Bronte Beach via the stormwater drain at the northern end of the beach and elevated enterococci levels were recorded in the immediate vicinity of the drain.

Beachwatch recommends that swimming be avoided for one day after heavy rainfall at ocean beaches and for up to three days after rainfall at harbour beaches.

The enterococci levels in the samples collected during May were below the 40 cfu/100 mL at all sampling sites in Sydney Harbour except Northbridge Baths (110 cfu/100mL), Chiswick Baths (125 cfu/100mL), Dawn Fraser Pool (61 cfu/100mL) and Parsley Bay (50 cfu/100mL).

The rainfall during May was 136 mm, which is just above the long term average of 121 mm.
