Testing Domestic Water and Private Wells

We test domestic water supplies and 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.


In the interest of keeping costs down, we have 4 strategically located sites around Ireland where you can drop off your water samples and we therefore do not charge for shipping.  If this is not convenient, sample bottles can also be returned to our Clonmel lab by Swiftpost at your cost.


Domestic Drinking Water Analysis

Our standard list of tests are as detailed in the table below. All analysis is performed at our laboratories in Clonmel with the exception of Iron and Manganese which are subcontracted to another lab within the ALS Group that holds accreditation for this analysis.

Why should I test my drinking water 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.
