Home grown veggies are safe - if watered with tap or rainwater
Rainwater and mains water (tap water) are not affected by groundwater contamination.
Home-grown fruit and vegetables are safe to consume, provided you are not watering them with bore water.
Sites that were formerly industrial may have further restrictions that you should be aware of. Please see the Form 1 Statement that was provided to you at the time of purchase, or contact the EPA if you would like to find out more information.
