Testing does not make water safe and it can be costly. Before contacting a laboratory you are advised to obtain appropriate advice as follows:
Your water supply company tests water daily in your area and will give you the results free of charge on request. This is also available on many water company websites.
Private water supplies
Your local authority will provide advice on any testing and arrange for this to be carried out on your behalf.
A list of laboratories that carry out water testing can be found here.
