Testing Domestic Water

We test private drinking water wells to our standard list of tests and/or to customer requirements.

Why Should I Test my Water?


Proper maintenance of wells is important to avoid illness. Contaminated water may not look cloudy, it may not smell differently or taste strange but the water that you are drinking could still carry a health risk. Regular testing is therefore advised to identify if there is contamination present and if treatment is necessary. This applies to users of private wells, hotels, nurseries, schools, colleges, creches, fruit and veg providers, hospitals, golf clubs and any other situation where water is stored prior to drinking.
