The risk of catching an infectious disease from swimming in clear, clean water is usually low. However, after rainfall contamination occurs through runoff into waterways and there is an increased chance that you may catch a gut, ear, skin or respiratory infection.
The Marlborough District Council and Nelson/Marlborough District Health Board Public Health Service advise that after rainfall, it is best not to swim in discoloured water, especially for at least the first 24 hours and preferably 36 hours to minimise the risk of exposure to harmful bacteria. Further reduce your risk by:
- Avoiding areas where stormwater outlets discharge to watercourses
- Avoiding areas with high runoff from intensive agriculture
Unlikely to be contaminated
Increased risk of illness/infection through contact with water
Significant risk of illness/infection through contact with water
Sites that have been sampled for at least five years have a Suitability for Recreation Grade (SFRG). The SFRG gives an indication for the general suitability of a beach for contact recreation. Apart from the microbiological results obtained through sampling, the analysis includes a risk assessment based on land use in the vicinity of the site. Sites close to areas of intensive agriculture and urban sites receive lower grades.
