  1. BROWNFIELDS BROWNFIELDS RESEARCH AND LAB

  2. BROWNFIELDS AND WATER POLLUTION AFTER BEFORE

  3. The Water Cycle Driven by Radiant Energy from the Sun.

  4. WATER ON THE GROUND: Surface Water Haddam Surface Water Resources Rivers Streams Wetlands

  5. Surface Water Killingworth’s Surface Water Resources Rivers Streams Wetlands

  6. Surface Water Drainage System – Small streams flowing into larger streams and rivers.

  7. Drainage Systems are called Watersheds Watersheds are used to manage water. Map Key: Watershed Boundary Movement of water

  8. Drainage Divide – ridge separating watersheds What is a Watershed? A Watershed is an area of land that drains to a single outlet.

  9. Major Watersheds in Connecticut HKHS South Central Coastal Long Island Sound

  10. U.S. DRAINAGE BASINSWater flow =

  11. What happens when the watershed is polluted?

  12. Brownfield Sites Threaten Water Resources

  13. What is a Brownfield? A BROWNFIELD is property that is not being redeveloped because it is or might be contaminated.

  14. What is a Brownfield? EPA’s Brownfields Program: Helps states and communities clean up and reuse brownfields for economic development. • HELPS TO: • Protect the Environment • Build Partnerships between businesses & towns • Strengthen the Marketplace • Improve a community’s long-term quality of life

  15. Brownfields Redeveloped

  16. CT Brownfields Connecticut’s Bureau of Waste Management -oversees CT Brownfields clean up programs Connecticut’s SUSPECTED sites: http://www.ct.gov/dep/cwp/view.asp?a=2715&q=324930&depNav_GID=1626 There are over 290 sites in Connecticut. http://www.ctbrownfields.com/default.asp

  17. CT Brownfields

  18. Investigating a Brownfield Site CAPT – Science, Technology & Society STEP 1 - What do you knowabout the site? Location: 7 Candlewood Hill Rd Past Use: Farm Equipment Manufacturing

  19. Investigating a Brownfield Site CAPT – Science, Technology & Society STEP 1 - What do you knowabout the site? What do you see?

  20. Investigating a Brownfield Site CAPT – Science, Technology & Society STEP 1 - What do you know about the site? Natural Resources– Is there surface water? CT River Candlewood Hill Brook

  21. Investigating a Brownfield Site CAPT – Science, Technology & Society STEP 1- What do you know about the site? Natural Resources– Is there Ground Water?

  22. Investigating a Brownfield Site CAPT – Science, Technology & Society STEP 2 - What are the suspected contaminants? Look at your “Brownfield Contaminants Guide”.

  23. Investigating a Brownfield Site CAPT – Science, Technology & Society STEP 2 - What are the suspected contaminants? • The Town of Haddam has found that the site may contain: • Heavy metals • volatile organic compounds (VOCs) • pesticides and herbicides

  24. Investigating a Brownfield Site CAPT – Science, Technology & Society STEP 3 - What do the suspected contaminants threaten? • Heavy metals: • Poisoning • Nerve and brain damage • Allergic reactions • Tiredness and headaches • Birth defects and miscarriages in humans and • other animals Pesticides and Herbicides: are designed to kill and harm, are carcinogens, and irritate skin and eyes

  25. Investigating a Brownfield Site CAPT – Science, Technology & Society STEP 4 – Design an Investigation to determine extent of contamination. Your suspected contaminants and site map are your guide.

  26. WHAT DO YOU SEE?
