LEAD IN DRINKING WATER

The Drinking Water Quality Regulator for Scotland (DWQR) has established a project to review policy to drive achievement of a reduction of exposure to lead in drinking water. The project seeks to identify enablers and strengthen or introduce mechanisms with a range of stakeholders and influencers for the removal of lead service pipes and plumbing.

In drinking water quality legislation, the limit for lead in drinking water has progressively reduced over the past 30 years to 10µg/l (micrograms per litre). Over the same period however, concerns have developed within Scotland’s health professional community that even the 10 standard may be too high and there is an increasing view that we should strive to reduce lead levels in drinking water as far as is practicably possible.

The specific aims of the project are to:

• Ensure there is a clear and shared understanding of legislation as it relates to duties on drinking water suppliers

• Engage with health officials to identify common themes and to align drinking water quality policy with health policy

• Work with stakeholders to identify areas where policy can be aligned to ensure the risk of exposure to lead in the environment is minimised

• Investigate the various policy options available and work with our SG colleagues in determining the best way forward

A clear area of focus for the project has been to review information provided by key stakeholders on lead.This revealed a substantial variation in the existence of any information at all, across influencer organisations. Where it existed, the quality of information varied and its accessibility presented a confused position to anyone needing to find out about the issue in Scotland. A significant element therefore has been to establish clear and authoritative information on the impact of lead on health. This is now hosted on the NHS Inform website and all stakeholders have taken on board the need to have on their own websites, agreed signposting information and links to the NHS Inform information.

A key sector of consumers at risk from lead in drinking water are children and babies. They absorb more lead than adults due to their growing bones and other organs within which lead can be deposited and accumulate as they develop. It is important therefore that we can have certainty that Schools and Nursery premises are free from lead. It is believed that attention to the removal of lead had been carried out in the past but in support of the project, local authorities have undertaken surveys of all their owned properties to ensure there is certainty around the issue.

A further survey is to be undertaken on behalf of DWQR to ensure a similar lead free status can be confidently expressed for all private schools and independent nursery premises.

The Care Inspectorate has been an integral part of the drive to ensure the risk of exposure to lead within care premises is addressed and they have adopted measures in their design principles for nursery provision and registration of new care services to ensure the importance of having a lead free water supply is actioned. Their Summer 2017 edition of Care News carries an item highlighting the issues.

As part of the drive to provide clearer information to consumers, Scottish Water has reviewed all of its’ letters and information leaflets relating to lead.

In conjunction with Scottish & Northern Ireland Plumbing Employers Federation (SNIPEF), and the Water Regulations Advisory Scheme (WRAS) they have produced a briefing note for housing Developers to raise awareness of the need to check for lead pipes and the removal of pipes and fittings where they are found. The note also highlights the illegality of using leaded solder on water supply pipework within the home and promotes awareness of the dangers of lead arising from the use of inferior quality brass fittings and taps.
