Student Project: Constructed Soils for Green and Sustainable Cities (Cheng Lab)

Urban soils are largely contaminated, while clean soils are often limited – despite the growing needs from greening and urban agriculture sectors. Healthy urban soil is the cornerstone of sustainable and resilient cities. In New York City, constructed soils (mixture of clean sediments and compost material) is abundantly available. Pilot projects all around the city have been conducted but the soil quality and performances have not been systematically monitored. This project aims to sample constructed soils used for various purposes in the past decade, examine soil quality/health, and document the performances for respective land uses. The data will inform policy decisions on the expanded, large scale use of such materials. The BUEE student will learn to sample and analyze soils, as well as learn about the research process for issues related to environmental policy.
