Frequently asked questions

Why should I test my soil?

Soil testing can provide important information on the condition of the soil, including contaminants (eg heavy metals and pesticides). The Laboratory offers a variety of soil testing services including contaminant and Acid Sulfate soil determinations (screening and chromium suite). Contact the lab to determine the best suite of tests fit for purpose.


Why should I test my water?

Your water may contain pathogens, including microbes, fungi or bacteria, which can, in some cases, be harmful to your health. Contaminants may change the taste, odour or appearance of your water. It may stain clothes, harm your appliances (ie washing machines) and even corrode your pipes.

If you are connected to the town water supply, you can rest easy knowing that the Tweed Shire Council regularly tests your drinking water to ensure it is safe. If you are not connected to town water, you may wish to have your water regularly tested.

If you're on the land, then you'll know just how precious your bores, wells, creeks, rivers and farm dams are. Water quality can affect plants, soils, livestock, irrigation equipment and general farm productivity. If you have any doubts about the quality of water you intend to use for irrigation, stock or domestic purposes, you should have it tested.

Swimming pools can also harbour bacteria, algae and other microbes that can not only change the colour of the water, but can also cause health issues for swimmers including ear, nose and throat infections. Regularly testing your swimming pool is recommended to ensure that it is healthy and safe to swim in.


Is rainwater safe to drink?

The Tweed's town water supply remains the most reliable source of safe and quality drinking water for the community. If you have access to town water, NSW Health recommends limiting the use of rainwater to other uses, such as toilet flushing, washing clothes, watering the garden, washing the car, filling swimming pools and fire fighting.

Rainwater tanks are generally NOT recommended for drinking from in urban areas due to traffic and industry emmissions that can settle on roofs.

Monitoring your water quality closely will help you to quickly detect potential contaminants, which may pose a risk to your health. The tank itself will need to be cleaned out from time to time. If in doubt, you may want to have your water tested at the Tweed Laboratory Centre.
