How is the City Reducing the Risks of Lead in Water?This is how the city instructs residents to collect water samples:
City of Raleigh Public Utilities Department maintains an active program to minimize the risk of lead exposure through its drinking water supply. Operations staff carefully monitor and adjust pH levels of water to a specific range that reduces the corrosive nature of the water, and corrosion inhibitor is added in our water treatment process to create a protective film on pipes that reduces the release of metals, such as lead, from household plumbing.
The US EPA Lead and Copper Rule compliance is based on the 90th percentile of samples collected during each monitoring period from homes built in the target period between 1982 and 1985 or homes served by lead service lines. The City of Raleigh system is below the action level for lead and below the maximum contaminant level (MCL) for copper and is in compliance with the Lead and Copper Rule.
The City of Raleigh has always been in compliance with the EPA Lead and Copper Rule. The City is currently on reduced monitoring for lead and copper and is required to monitor for lead and copper every three years. Based on the population served, the City is required to monitor at least 50 homes for lead and copper during the compliance year. We currently have 110 homes listed in our Lead and Copper Compliance Monitoring Plan.
The City of Raleigh stays proactive when it comes to public health and safety, in addition to our compliance monitoring; the City has a Volunteer Lead and Copper Program. This allows our customers to have their water tested anytime for lead and copper by our laboratory staff at no cost to the customer.
