What is a Brownfield Site? Piece of land that was once used for industrial
purposes and is now typically abandoned
because of suspected contamination.

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.
Mercury BenzeneArsenic

Contaminants of Major Concern Asbestos – Cause respiratory problems Pesticides – Cause cancer & birth defects Benzene – Causes cancer Lead and Copper - Neurotoxic Mercury – May cause physical and mental
disorders. PCBs – Possible cause of cancer & birth defects

Think… Think of another site/place in Greenwich that
might become a Brownfield site in the future.
How would a site become contaminated?

Where do contaminants come from?
Contaminants Possible source of contamination
Heavy metals:
arsenic, cadmium chromium, lead, mercury
metal finishing/plating shops,
manufacturing and foundries, coal burning
power plants
Gasoline/constituents of gasoline:
gasoline, benzene, ethylbenzene, toluene,
xylene
gasoline stations, tank farms, pipelines
Petroleum Products Leaking undergound storage tanks
Solvents:
tetrachloroethlyene, trichloroethylene,
III-trichloroethane
dry cleaners, machine shops,
metal finishing/plating shops

Remediation: Making Brownfield sites safe and usable again…
Identify and measure contaminants Determine the safety risks Stop the contaminants from spreading Remove or isolate the contaminants

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

Your Task
11
1. Formulate a question/problem statement
about a Brownfield site that can be answered
through a scientific experiment/investigation.
2. Design a scientific experiment/investigation
that answers your question/problem statement.
