Can you drink water from a Borehole?

by | Nov 15, 2021

There are many reasons that someone might get a borehole drilled. The most common of which is to access groundwater as a self-sufficient water source for businesses or for family homes. Businesses and homes alike can extract up to 20,000 litres of water a day without a license, making it a very cost-effective, long-term investment. However, due to the water not being treated like mains water, it may leave people questioning if borehole water is safe to drink. Today we aim to answer that question and also a few other questions that may arise surrounding this particular topic.

Is Borehole water safe to drink?

Water that is safe to drink is known as potable (pronounced POE-tuh-bull) water. Borehole water is generally potable, although if you are indeed planning on drinking it, the water should be tested first. It’s better to be safe than sorry! Due to the water being from a 100% natural source, it could contain too much iron, calcium or magnesium, as well as other minerals and bacterium, which could be slightly dangerous in high amounts or for the vulnerable. This test and the following solutions will ensure that your borehole water adheres to the UK Private Water Supply regulations.

Should borehole water be too high in any of these minerals or bacterium, or if pH levels are too low there are methods available to treat the water before it reaches your taps. There are filters available which can reduce mineral levels and also filter out sediment such as sand. There are chemicals which can treat the water’s pH levels and levels of some minerals, whilst UV lights can be used to sterilise the water and kill off bacterium.

Water should be tested regularly to ensure there have not been any changes in water quality. Yearly should suffice, just to check that there isn’t excess minerals or bacteria building up in your well. However, if you notice a change in taste or odour, you should test it a little more regularly as it could indicate a major change in the make-up of your well water. You should also test the water at least twice a year if an infant, an elderly person or a pregnant person is living with you.

You should also more regularly test water if there has been nearby construction works or works using chemicals, if there has been flooding or if anyone in the house has persistent gastrointestinal illnesses.
