Hawke’s Bay: Rain causes swimming warnings
7 December 2006
Recent rain causes swimming warnings throughout Hawke’s Bay
Recent heavy rain has caused pollution to contaminate many Hawke’s Bay waterways, says Hawke’s Bay’s District Health Board medical officer of Health, Dr Caroline McElnay.
Dr McElnay is advising people to avoid all recreational waterways such as lagoons, streams, and rivers until at least three days after heavy rain.
Waterways that are known to currently contain high levels of bacteria, from sampling undertaken on 5th December 2006 include:
Maraetotara Lagoon at Te Awanga
Puhokio Stream at Waimarama
Warning signs have been erected by Hastings District Council
Monitoring by Hawke’s Bay Regional Council has shown levels of bacterial pollution that exceed the levels recommended in the Ministries of Health and Environment’s recreational water guidelines. The level of these bacteria indicates excessive amounts of faecal matter, either animal or human, present in the water.
The Public Health Unit would like to remind people that all surface water should be assessed before swimming by checking that the water is clear – You should be able to see your feet when knee deep in the water. Clear water is generally a sign it is free from contamination.
“This is definitely a good time to use a swimming pool,” Dr McElnay said.
The Public Health Unit operates a “Safe Swimming Line” the number is (06) 878-1368. This line is updated regularly with information on sites that may be contaminated. Results are also available from the Hawke’s Bay Regional Council website www.hbrc.govt.nz.
