260,000 Lead Pipes May Deliver Water to Homes in Minnesota

Minnesota ranks 10th in nation with most lead pipes

WASHINGTON – Minnesota has the tenth-highest number of lead pipes of any state in the nation and the tenth-highest number per capita nationwide at 4,556 lead lines per 100,000 people, according to a new survey from NRDC (Natural Resources Defense Council). An estimated 260,000 or more lead service lines carry drinking water to Minnesotans who may not suspect their tap water could be contaminated with lead. 

NRDC's new national survey of lead service lines – the lead pipes that carry water from water mains under the street to homes – found between 9.7 million and 12.8 million lead pipes are connected to residences. All 50 states have lead pipes carrying drinking water to as many as 12 million people, and potentially more, who may not suspect their tap water is contaminated with lead. There is no safe level of lead, which causes irreversible harm to people’s health, particularly for children. 

“Drinking water won’t be safe until the country pulls the millions of lead pipes out of the ground found in every state,” said Erik D. Olson, senior strategic director for health at NRDC. “President Biden’s American Jobs Plan is a historic opportunity to fix the nation’s lead pipe crisis. Removing lead pipes will improve health and create jobs, starting in low-income communities and communities of color with the highest rates of lead exposure.”  

NRDC’s survey also found:  

  • Minnesota has the tenth-highest number of lead pipes in the U.S. The top 10 states with the most lead pipes, ranked in numeric order, are as follows: IL, OH, MI, NY, NJ, MO, WI, IN, TX, MN. Together these 10 states have nearly four million lead pipes.   
  • Lead pipes are found in every state in the nation. It is not an urban issue; rural states have lead pipes, too.     
  • Minnesota has the tenth-highest number of lead pipes per capita in the U.S. The top 10 states with the most lead pipes per 100,000 people are as follows: WI, OH, KS, MO, IL, IA, NE, DC, MI, MN.    
  • Minnesota was one of four states (HI, MN, VA, WA) that could provide NRDC with data for only part of the state, which rendered it unusable for survey purposes. 
  • NRDC estimates there may be up to 12.8 million lead pipes: NRDC confirmed 6.2 million known lead pipes; additionally, there are from 3.5 million to as many as 6.6 million service lines that are currently of unknown material that are projected to be lead. 

Flint, Michigan’s water crisis, the result of massive lead contamination of its drinking water, provided the nation and the world a glimpse into the frailty of aging water infrastructure in Flint and beyond. President Biden’s American Jobs Plan would help every community in the nation remove its lead pipes, by providing $45 billion to states to pull lead pipes out of the ground – creating high quality jobs while helping to eliminate the public health disaster of lead-contaminated drinking water. Biden’s plan would create a comprehensive package of strategic investments that address critical priorities, like improving the nation’s failing water infrastructure, and climate action in a moment the nation urgently needs both.    

NRDC collected data through a survey of all 50 states and Washington, D.C. For the 40 states that either fail to track or could not provide an estimate of the number of lead pipes in the ground statewide – which includes Minnesota – NRDC relied upon a 2016 voluntary industry survey that federal auditors called a “lower bound estimate” of the number of lead lines. NRDC then projected the number of additional lead service lines that are likely to be present among the pipes of unknown composition based on data collected from other states.
