The New York City Urban Soils Institute (USI) Was Founded By A Partnership Between The New York City Soil & Water Conservation District, The USDA-Natural Resources Conservation Service, Brooklyn College, And The Gaia Institute. The Mission Of The USI Is To Advance The Scientific Understanding And Promote The Sustainable Use Of Urban Soils Through Research, Education, And Conservation. As New York City Adopts Green Infrastructure, Urban Agriculture, Climate Resiliency, Ecological Restoration Our Interactions With Urban Soils Have Rapidly Increased In The Past Few Years. However, Our Understanding Of Urban Soils Has Not Kept Pace. There Is An Unmet Need For Programs That Collaborate And Support Efforts In Sustainable Resource Use And Management. In Cities, We Face Paramount Decisions And Seek Innovative Solutions For Issues Related To Legacy Contamination, Climate Resiliency And A More Sustainable Future, And We Realize That The Solutions Rely Heavily On The Understanding And Proper Use Of Soils And Stormwater. The USI Has Been Developing Workshops And Field Trainings, Mobile Exhibits, And Leading Urban Soils Research In New York City And Other Areas, To Increase Local Knowledge And Foster The Next Generation Of Soil Scientists. We Work Closely With Our Local Community Organizations, Strengthening The Knowledge-Dissemination Through Partnerships. We Offer A Wide Range Of Soils Training Opportunities From Lectures To Hands-On Field Sessions For All Ages. We Also Developed Curriculum And Internship Programs For College And Graduate School Level Students. The USI Is In Its First Year. We Would Like To Share With You Our Methods, Formats And Our Case Studies; Trials And Successes.

Phosphate Amendment Is Being Promoted As A Cost Effective Means Of Reducing Lead (Pb) Hazards In Soil Via The Formation Of Stable Lead-Phosphate Minerals. However, The Application Of Phosphate In Soil Can Potentially Mobilize Arsenic (As), A Known Human Carcinogen. This Study Uses A Combination Of Lab And Field Experiments To Examine The Pb Binding And As Mobilization Potential For Bone Meal, Triple Super Phosphate, And Two Types Of Composts, With Or Without Iron And Manganese Amendments. Common Produce Was Grown In Test Plots At A Farm In New Jersey, Where The Soil Mean Concentration Of As Was 36 Mg Kg-1 And Pb Was 219 Mg Kg-1. An In Vitro Method (Modified From The RBA Method: EPA 9200.2-86) Is Used To Assess Bioaccessibility Of Pb And As For Soils Before And After Treatments. In General, Phosphate-Bearing Amendments Didn’t Have A Significant Effect On Pb Bioaccessibility In Soils But They Increased As Bioaccessibility. Overall, The Effect Of A Plant Type Was More Important Than The Effect Of The Various Types Of Amendments On Pb And As Vegetable Concentration. In General, Root Crops Had The Highest Concentrations Of Pb And As, Followed By Leafy Vegetables And Then Fruits. Evidence Show That Dust And Dirt Particles Are The Dominant Contributors To Plant Tissue Pb Or As Concentrations. These Findings Support The Idea To Grow Fruit Crop In Preference To Leafy And Root Crops. Vegetable Selection, Best Management Practices (Washing, Peeling, Etc.), Dust Control Measures, And Conservation Practices Should Be Applied To Reduce Exposure And To Mitigate The Health Risk From Soil Contamination.

Urban Gardening Provides Valuable Benefits To Participants And Local Residents, Including Access To Healthy Food, Reduced Reliance On Food Transportation And Distribution Systems, Improved Air Quality, Increased Physical Activity, And Space For Community Building And Cultural Exchange, While Making Use Of Otherwise Abandoned Lands. However, Urban Soils Are Often Contaminated, Most Frequently In Urban Centers Where Lead Persists As The Toxin With The Most Severe Health Implications. Gardening Activities May Increase Human Contact With Contaminated Soil And May Bring Greater Health Risks, Especially For Young Children. Constructing Raised Beds And Covering Walkways Are The Most Commonly Used Methods To Minimize The Health Risks Of Urban Gardening In Contaminated Soils; However, The Availability Of Clean Soil Is Limited For Large Cities. Tens Of Thousands Of Cubic Yards Of Pristine Sediments Are Generated From Development Sites Each Year. Organic Waste Recycling Initiatives Are Also Generating Large Quantities Of Compost That Can Be Readily Mixed With The Clean Sediments To Create Soils To Meet The Needs Of Community Gardens In The City. The Clean Soil Bank Program Not Only Produces Clean Soil For Healthy Gardening On A Large Scale, But Also Helps Reduce Organic Waste Problems In Urban Areas. This Program Can Potentially Serve As A Model For Other Cities In The Quest For A Sustainable Future. A Pilot Project Was Conducted To Evaluate The Potential Contaminants In Compost Material, Contamination During Transportation And Gardening Processes, Potential Re-Contamination By Soils And Dust Surrounding The Raised Beds, As Well As The Agronomic Value Of Different Ratios Of Sediment And Compost Mixes. Keywords: Urban Gardening, Soil Contamination, Sustainability, Clean Soil Bank

The New York City Department Of Environmental Protection (DEP) Installed Various Green Infrastructure Demonstration Pilots As Part Of Its 2007 Jamaica Bay Watershed Protection Plan, Nitrogen Consent Order And Combined Sewer Overflow (CSO) Consent Order Environmental Benefit Projects With The New York State Department Of Environmental Conservation (NYSDEC), The City’s 2008 Sustainable Stormwater Management Plan And The September 2010 Green Infrastructure Plan. These Pilots Include Five Streetside Infiltration Swales (SSIS), Five Enhanced Tree Pits (ETP), One Wet Meadow, One Green Roof, One Blue Roof, And Four Rain Gardens On Parking Lots. For Enhanced Tree Pits, Stormchamber, Crushed Stone And Recycled Glass Were Employed And Compared. The 15 Pilots Were Built At 11 Locations In Brooklyn, Queens And Far Rockaway, And On Three Different Landforms. Five Of The Systems Are In Parking Lots, Whereas Ten Are On Street Sidewalk. These Demonstration Studies Are Used To Help Identify Effective Measures To Reduce Stormwater Flows To The City’s Sewer System During Storm Events. The Soils At Each Site Also Function To Retain Part Of The Stormwater To Sustain Healthier Plant Growth, Thereby Establish A Dynamic Mico Ecosystem To Better The Local Urban Environment And For Carbon Storage. Tree And Plant Roots And Microbial Activities In Turn Promote A Functioning Rhizosphere That Helps To Improve And Maintain Good Infiltration Rates. The Soils Also Serve As Natural Filters To Remove And Breakdown Contaminants And Excess Nutrients From Runoff. Stormwater Capture Volume And Efficiency, Storage, As Well As The Quality Of Runoff Water And Sediments/Soils, Have Been Monitored To Evaluate The Pros And Cons Of Each Design, Implementation Cost, Benefits And Identify Specific Maintenance Requirements.
