Testing Domestic Water
We test private drinking water wells to our standard list of tests and/or to customer requirements. ALS Life Sciences advise that private well owners test their drinking water supply annually, particularly after a spell of bad weather to identify if treatment is required.

Why should I test my well?
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.
