If you have concerns about the drinking water supply, you should contact the water company in the first instance. They should be able to give you some advice and test the water if necessary. If you are not sure who supplies your drinking water please click here.
If you have already contacted them, you can try the environmental health office at the local authority.
The last option is to have the water tested privately for which there will be a charge. You can find your nearest approved laboratory by clicking here.
