Lead Remediation

Lead and copper exposure, especially for children, can cause very serious health problems, including decreased bone and muscle growth, damage to the nervous system and kidneys and developmental delays. In adults, lead and copper exposure can cause kidney failure and high blood pressure.

In the summer of 2015, Hong Kong residents discovered some alarming information regarding lead in their drinking water. An estimated 30,000 public housing units and an undisclosed number of schools and private housing units were shown to have lead levels of well over the World Health Organisation's (WHO) cut off level of 10ug/I (10 parts per billion).

Objective:

To assess the reduction in lead concentration at the customer's tap after lining a 42m long supply and communication pipe using the ePIPE process. Initial lead reading 7.45µg/l.

In the UK a significant number of properties are supplied using a lead service pipe. Lead is a cumulative poison that affects the nervous system and children are particularly vulnerable as it affects both their physical and intellectual development. Lead service pipes are the main contributor of dissolved lead in drinking water and on average about 75 – 80% of the lengths of those pipes are located on the private side and owned by the customer Best endeavours in the battle against lead have historically been through plumbo-solvency control at the treatment source plus relatively small amounts of company side pipe replacement.

In December 2013 the EU will adopt the new World Health Organization (WHO) quality standard for lead in drinking water of 10 μg/l (10 ppb). The ePIPE lining and system of application provides an effective answer to water pipe communication or supply line replacement for either lead or leakage programmes.

The Problem:

The copper pipes of the potable water system in the housing dorms on San Clemente Island were originally installed using lead based solder. As a result, the lead levels in the dorms’ potable water system exceeded allowable limits by as much as 900%. Pre-test water samples were taken and lead levels in the water were determined to be 135 ppb versus the allowable limit of 15 ppb.

Lydney is a small town on the west bank of the River Severn, close to the Forest of Dean. Around 100 residential properties, in four areas across the town, were selected to have their service pipes, from the mains connection in the street to the first tap inside the property, treated with ePIPE technology from Pipe Restoration Services (PRS).

Since the lead water scandal in Flint was uncovered there’s been a growing health concern over poisonous pipes releasing unsafe lead & copper levels into drinking water. Today there are still millions of lead pipes in the ground around the world releasing dangerous amounts of lead into drinking water. The problem of lead leaching into drinking water is not just limited to lead service lines. Lead can also find its way into water from lead solder and brass fixtures used in water piping systems in homes and building built before 1986.
