Why do I need to get my water tested?

  • If you get your water from your own private well or small group scheme, it is your own responsibility to ensure that it is safe to drink. No one else will alert you to the fact that it could be contaminated with chemicals. Nor will you get a boil notice from Irish Water if bugs have entered you water supply, as a result of run off from animal slurry, septic tanks or other sources.
  • The EPA recommends that you get your private well or small private group scheme drinking water tested  in an INAB accredited laboratory once every year  for microbial contamination and once every three years for chemical contamination.
  • If your private well or group scheme supplies more than 50 people or a commercial business (such as a creche, hotel, restaurant or care home) you are LEGALLY REQUIRED to have you water supply tested twice a year for microbial contamination.

Are there microbes (bugs) in my water?

  • Our microbial water analysis test package will tell if you water is contaminated by microorganisms (bugs), which can cause frequent stomach upsets, especially to children, the elderly, those with a weakened immune system or visitors to your home, who may not be used to drinking the water.
  • The EPA estimates that between 15% and 30% of household wells are contaminated with a bacterium (bug) known as Escherichia coli (usually shortened to E. coli).
  • This bug can enter your well or private water supply as a result of cattle grazing nearby, run-off from slurry being spread on nearby land or runoff from a nearby septic tank that has been badly sited or is in some way defective.

Are there chemicals  in my water?

  • Our chemicals test package will provide you with information such as whether part of your plumbing system may still contain lead (only a risk in pre-1970s properties) or whether your drinking water may contain elevated levels of nitrite/nitrate, which can be harmful especially to bottle-fed infants
  • It will explain why you might be having issues such as staining of sanitary ware. Blue/green is usually attributable to copper, while red/brown staining normally occurs as a result of elevated iron or manganese levels.
  •  It will put a value or the hardness or otherwise of your water – or, at the other end of the scale, its acidity – and potential to corrode your pipes and hot water tank.

Is there a grant to pay for any necessary work? 

If your water analysis test indicates that the quality of drinking water from your well or small private group doesn’t meet Irish Drinking Water Standards, you may be eligible for a grant from your local authority to carry out improvement works to your water supply system – provided you meet certain eligibility criteria.
