In Scotland, lead does not occur naturally in significant concentrations in our water supplies. The problem arises when drinking water comes into contact with lead supply pipes, lead tanks, lead solder joints on copper pipes, or inferior quality brass fittings and taps, particularly for longer periods (e.g. overnight/ weekends / holidays periods). This can result in high lead levels in the drinking water supply. All drinking water is required to meet the tighter standard for lead (10µg/l) that came into force in December 2013.
For further information on lead and the importance of removing it from the water supply route into premises can be found in the Information section of this website. Click here: Lead in Drinking Water
