Sprayed chemicals are extensively used in agriculture and horticulture for control of pests and weeds. This spray can drift over neighbouring properties, waterways and water tanks, this is referred to as spray drift. Spray drift can affect human, animal and environmental health. Spray drift can affect household and farm water supplies, including tank water.
The health impacts of exposure can depend on how and where the chemical is applied, the amount of drift, weather conditions and the toxicity of the chemical. If you have been exposed to chemical sprays through spray drift, and are concerned, there are a number of agencies you can contact for help.

- Spray drift can affect the environment, your health and the health of your family and neighbours.
- Spray only if the weather is suitable (a steady 3-15km wind is ideal).
- If you use tank water and spray lands on your roof, disconnect the collection pipe until it has rained or until the roof has been cleaned.
