  1. GHS ScienceCAPT Embedded Task Review Brownfield Sites

  2. Your Task Formulate a question/problem statement about a Brownfield site that can be answered through a scientific experiment/investigation. Design a scientific experiment/investigation that answers your question/problem statement. 2

  3. What is a Brownfield Site? • Piece of land that was once used for industrial purposes and is now typically abandoned because of suspected contamination. • Name one Brownfield site in Greenwich? • What has this property been used for that led to it being • identified as a Brownfield (contaminated) site?

  4. What is a contaminant? • A contaminant is a toxic chemical that can harm humans and/or the environment. • Contaminants can pollute water, air, and/or soil. Arsenic Mercury Benzene

  5. Contaminants of Major Concern • Asbestos – Cause respiratory problems • Benzene – Causes cancer • Lead and Copper - Neurotoxic • Mercury – May cause physical and mental disorders. Greatly affects fish populations.

  6. Where do contaminants come from?

  7. Why Redevelop Brownfield Sites? • Discounted real estate cost • Valuable location • Reduce pressure on undeveloped land • Preserve historical or architecturally significant buildings • Eliminate health and safety hazards • Improve community

  8. Detecting Soil and Groundwater Contamination • Usually a portable drilling rig is brought to the site • A well is installed. Soil is sampled as the well is drilled. • Groundwater is sampled and analyzed for the suspected pollutants.

  9. How to make a Brownfield site usable again… • Get rid of contaminants (ex. Excavation techniques) • Stop the contaminants from spreading

  10. Your Task Formulate a question/problem statement about a Brownfield site that can be answered through a scientific experiment/investigation. Design a scientific experiment/investigation that answers your question/problem statement. 10
