  • 7. Introduction
    • The major focus of the Hurricane Katrina recovery has been placed on the financial aspects of the city, infrastructure and housing while the environmental effects of this tragedy continues to be placed on the back burner. The environmental health of Hurricane Katrina survivors is equally as important as the above mentioned issues.
  • 8.
    • There are thousands of people who will not fully recover from this devastating event until they receive the help necessary for them to cope with their new “Post Katrina Life.” People are suffering from health problems because of lack of understanding of how this entire situation came about. People have so many unanswered questions about Hurricane Katrina.
  • 9.
    • Abstract
    • We will address the areas of soil testing, and air quality. The tests were conducted by the Environmental Protection Agency and the Natural Defense Resources Council.
    • The question remains unanswered is New Orleans is a healthy city to live in post Katrina?

  • 17. Tests Results
    • The following results were revealed:
    • Arsenic
    • Diesel Fuel
    • Others
  • 18. Air Quality Tests
    • These tests were performed to determine if toxic chemicals are health risks to humans living in New Orleans .
  • 19. Air Quality Tests Results
    • Tests results revealed toxic levels of the following:
    • Cadmium
    • Chromium
    • Manganese
    • Mercury
    • Arsenic
    • Pesticides
    • Petroleum Hydrocarbons
    • All of these chemicals carry a very significant health risk to humans.
  • 20. Arsenic - High Levels
    • Orleans Parish Results:
    • Average Levels 12.2 (mg/kg)
    • 31 times higher than Region 6 EPA soil cleanup level for residential areas.
    • § Region 6 EPA Soil Cleanup Level 0.39 mg/kg
    • This level is standard to protect against cancer.
  • 21. Arsenic Health Risks
    • Levels of arsenic in the sediment Post Katrina are unacceptably high for residential living.
    • Arsenic is toxic to humans and causes cancer, and for this reason, no amount of arsenic is considered safe. Many scientific studies, including reviews by the National Academy of Sciences

  • 23. Pesticides Test Results
    • NRDC's testing detected elevated levels of several pesticides next to an abandoned industrial facility known as the Thompson-Hayward facility. It once housed a pesticide-blending company.
    • One of the samples collected outside the fence on the western corner of the facility, near some homes, revealed high levels of a variety of banned pesticides. The level of DDT and one of its breakdown products exceeded the Region 6 EPA soil cleanup levels by approximately twofold.
  • 24.
    • Two other pesticides:
    • Dieldrin
    • Heptachlor Epoxide
  • 25.
    • All of these pesticides have been banned in the United States for more than 25 years, and they are now also banned worldwide by international treaty because of their serious toxicity and environmental persistence.
  • 26. Polyaromatic Hydrocarbons
    • Independent testing by NRDC and others revealed high levels of polyaromatic hydrocarbons (PAHs) at one site in New Orleans. PAHs are cancer-causing chemicals from soot and petroleum-based products.
    • At the Agriculture Street Landfill Superfund site in the Bywater neighborhood, leachate was visibly leaking from the site and spreading across the street and onto the grounds of the local senior citizens' center.

    • Polyaromatic Hydrocarbons
    • Results:
    • Leachate
    • Benzo(a)anthracene
  • 29. Other Contaminants
    • Independent soil sampling revealed a variety of other contaminants including
    • Metals such as lead, cadmium, chromium and mercury.
    • Various pesticides and chemicals known as phthalates, which are used in plastics as a softener.
  • 30. Other Contaminants Continued
    • The lead level in one sediment sample taken on Treme Street was more than double the EPA soil cleanup level.
    • The EPA took a sediment sample in that same area, at Treme and St. Phillip, and found similarly high lead levels. These sampling results indicate a lead contamination problem in this area that

  • 32. The People of New Orleans Deserve a Safe Living Environment
    • “ The EPA has a legal and moral obligation to assure that the public is fully protected from the harmful environmental conditions created by Hurricanes Katrina and subsequent flooding.”
    • The Residents of New Orleans, LA
  • 33.
    • In December of 2005 the LDEQ and the U.S. EPA announced their completed assessment of the environmental impact of Hurricanes Katrina and Rita
    • “ There are generally no unacceptable long term health risks directly attributable to environmental contamination resulting from the storms.”
  • 34. Health Issues and concerns for Returning Residents
    • NRDC (Natural Resources Defense Council)
    • EPA ( Environmental Protection Agency)
    • LDEQ ( Louisiana Department of Environmental Quality)
  • 35. Health Issues Related to Post Katrina Contaminants
    • Long Term Exposure
    • Arsenic can cause
    • skin, and lung cancer
    • can damage the liver and kidneys
    • is responsible for a variety of other serious aliments.
  • 36. Health Issues Related to Post Katrina Contaminants
    • Short Term Exposure
    • Short Term effects are related to dust, pollen, and mold.
    • Inhaled mold spores can cause congestion
    • Sneezing, itchy & running nose
    • Throat irritation
    • Allergy attacks
    • Pneumonia like symptoms
  • 37. At- Risk Categories
    • Children and Infants
    • The elderly
    • People with serious allergies
    • People with asthma
    • People with heart conditions
    • People with compromised immune systems
    • They should all avoid previously flooded areas of the city at this time.
  • 38. Health Advisory to New Orleans Area Residents
    • Don’t bring young children into areas that were heavily flooded
    • Avoid activities that stir up dust
    • Avoid eating and smoking in contaminated areas
    • Drink bottled water
    • Get rid of porous material that may be contaminated
    • Thoroughly air out your home
  • 39. Conclusion
    • Numerous tests and studies were conducted on the environment in New Orleans to determine if the environment is safe and healthy enough for residents to live in.
    • The test results indicated that the environment and the air quality had been comprised by the various toxic chemicals.
    • Results differed between the two testing agencies. (EPA & NRDC.)
    • At this point residents still have many unanswered questions concerning. Judging from the data presented; what do you think? Is New Orleans affectionately know as the
    • “ Big Easy”
    • A toxic gumbo?
