Keep streams and lakes clean
In parts of New Zealand, toilet wastes and rubbish contamination have already polluted the water in our lakes, rivers and waterfalls.
To lessen the risk of contamination and to protect water quality:
- Where there is a toilet, use it.
- In areas without toilet facilities bury your toilet waste. Choose a place at least 50 metres from tracks, huts, camping sites, popular areas and water sources. Dig a shallow hole 150mm deep with the soil's organic layer and bury all toilet waste and paper. This will stop the waste contaminating water sources. Using a small trowel will make it easier to bury toilet waste.
- When using water for washing yourself or your utensils, take the water and wash well away from the water source. Drain used water into the soil so that it is filtered before re-entering the lake or stream.
- As soaps and detergents are harmful to water life and other users, these should also be drained into the soil.
Giardia
The chances of contracting Giardia from water in New Zealand are increasing. Giardia is a parasite which can survive in cold water and it is mainly spread as a result of poorly disposed toilet waste. It infects the intestines, causing chronic diarrhoea, nausea, stomach cramps and dehydration.
The presence of this parasite, or other disease-causing bugs, in our waterways can seriously harm our health and enjoyment. To lessen their spread, it is essential to dispose of toilet waste correctly.
If you doubt the purity of the water for drinking you can:
- Boil the water for at least 3 minutes before drinking.
OR
- Chemically treat the water with purifying agents available from chemists and outdoor supply shops.
OR
- Filter the water through an approved filter system.
If you suspect that you have Giardia, see your doctor.
