PUREsoil NYC provides communities across the city access to high-quality soil for neighborhood projects & to help protect against climate change

  Mayor Bill de Blasio today announced the launch of PUREsoil NYC, an innovative initiative that recycles clean soil from construction projects in NYC to community uses, where it improves soil quality and increase resilience to the effects climate change. Under this program, the city will provide clean soil to community-based organizations to improve the quality of degraded soils in gardens, yards, and other open spaces and lower exposure to lead and other pollutants. Clean soil will also be used to create tidal and fresh water wetlands, berms, and levees and raise the elevation of coastal land to reduce risks from sea level rise and stronger storm surges caused by climate change. PUREsoil NYC and the source of the soil, the NYC Clean Soil Bank, are operated by the NYC Mayor’s Office of Environmental Remediation (MOER). PUREsoil NYC is the first city-run program of its kind in the world.

“Not only are we finding new uses for New York’s own, pristine soil, we are helping beautify neighborhoods and making communities more resilient,” said Mayor de Blasio. “This program is a global first, helping us build a better, fairer city.”

“The clean soil deep beneath our feet is one of the most precious natural resources we have in NYC.  Each year, hundreds of thousands of tons of surplus clean native soil are exported long distances out of our city. By keeping this soil in NYC and ‘upcycling’ it to its best use, we can improve the chemical quality of our urban soil to reduce pollutant exposures, build new wetlands, and raise our coastal land to prepare for the effects of climate change and sea level rise,” said Dr. Daniel Walsh, MOER Director and founder of the NYC Clean Soil Bank and PUREsoil NYC. “This administration recognizes the disproportionate risk from environmental pollution and climate change in disadvantaged communities and is focusing use of our natural resources to achieve equity in environmental quality and preparedness.”  

PUREsoil NYC seeks to achieve the highest uses for NYC’s surplus pristine soil resources and to prioritize this work in disadvantaged and vulnerable communities. The soil will be obtained from the NYC Clean Soil Bank, the nation’s only soil exchange and the only city-run soil exchange in the world.  Pristine soil is extracted from deep below the ground during construction of basements, underground parking and other underground structures. The soil is native sediment deposited by glaciers in NYC over 10,000 years ago and is among the highest-chemical-quality soil found in the northeast United States. PUREsoil NYC is part of MOER’s Progressive Urban Resource Exchange (PURE) initiative established under OneNYC.

Soil used in PUREsoil NYC is subject to a 12-step chemical quality vetting process to ensure purity.  Recent study by MOER and Columbia University’s Lamont-Doherty Earth Observatory showed that by retaining and recycling pristine native soil, soil exchange lowers soil transport distances by over 70% and provides a series of environmental benefits, including reductions in truck mileage on highways, fossil fuel consumption, and greenhouse gas and other air pollution emissions. Local sourcing of soil through the exchange also preserves NYC’s original soil character, conserves natural resources in regional quarries, and lowers costs of soil management by 85%. In the absence of programs like PUREsoil NYC that retain and recycle valuable native soil resources within NYC, studies have shown that over 95% of NYC’s clean soil resources are exported for uses outside of the city.

The NYC Clean Soil Bank and PUREsoil NYC are the only programs designed to retain clean soil resources within a city to achieve a broad set of environmental and societal goals. The design of PUREsoil NYC was guided by an intensive set of scientific studies by MOER, Lamont Doherty Earth Observatory Columbia University and Brooklyn College and is advised by a distinguished panel of soil scientists and other experts. Retention and upcycling of NYC’s clean soil resources is supported by over 350 soil scientists, engineers, environmental professionals, advocates, and community members in NYC.

“The Mayor’s Office of Environmental Remediation and its Clean Soil Bank program have been invaluable to building the city’s resiliency against climate change. The City’s Interim Flood Protection Program has relied on the soil bank to build flood control structures in Red Hook and Hunts Point to protect these communities from coastal storms,” said Jainey Bavishi, Director of the NYC Mayor’s Office of Recovery and Resiliency. “We’re excited to have PUREsoil NYC as a new tool to support the resiliency of our neighborhoods.”

“This approach is good government! Keeping our clean soil resources in NYC and using them for improving our environment and quality of life for our communities not only makes NYC resilient, but also conscientious, and sets an example in sustainability for the rest of the world,” said Tatiana Morin, Director of the New York City Urban Soils Institute.  “This program is supported by many soil scientists in NYC and has been vetted in scientific literature. It is absolutely a high priority for our organization and other soil resource leadership organizations.”
