Do you know
what's in your water?
Your drinking water can look, taste and smell completely normal, but that does not always tell you the full story.
Wheather your water comes from a private well, group water scheme or public supply, testing gives you a clear picture of the water you use every day.
Don't guess.
Know.
Why test your drinking water?
Water quality can change over time. Conditions around your water source and your supply may change, and some issues aren’t visable.
Heavy Rainfall
Run-off can carry contaminants towards private water sources
Changes near your well
Agriculture, land use or nearby wasterwater systems can affect groundwater.
Changes to your supply
Infrastructure and source changes can mean the water arriving at your tap changes over time.
Invisable contamination
Some microbiological contamination may not change how your water looks, tastes, or smells.
