Use a new bottle and cap. (1.5 – 2 Lt if the water is cloudy or coloured).
Rinse the bottle three times with the water to be sampled before taking the sample.
Fill the bottle with a representative sample of water and cap so there is little or no air in the bottle.
In dams or rivers, take the sample as close to the pump intake as possible.
In boreholes, let the pump run for 20 minutes before taking the sample from a point close to the pump.
Dry thoroughly and attach the completed label using clear tape to prevent it getting wet.
Keep the sample away from sunlight and in a cool place until it can be sent by courier to H2O | BWT SA.
It is recommended that a full SANS 241 Water analysis be done yearly to ensure all contaminants are within limits. This recommendation is where non-municipal water sources are being filtered / purified for human consumption and domestic usage.
