EPA Does More Testing For Dioxins

The AC Health Department still continues to show a positive spin on the fact that dioxin tests which are coming back from EPA directed soil surface samples, are still above state residential standards. Their postive spin comes from the fact that the levels are decreasing because they continue to move farther from the source, which would be predictable. The first tests were 100', then 200' now they are at 300' on the right of way of Aves 26th-31st on the west side of Koppers.
From what I understand, "above state residential standards" is not a good thing unlike when your child does a good thing by testing "above state standards". In this case, we need to stop with the confusion and tell it like it is. "Above state standards" is below human standards which, is almost comically funny if it weren't so tragic. Even our local NPR station mimed the spin this week by saying it was an improvement over the last sample analyzed in August.

Dioxins are classified as one of the worst Persistant Organic Pollutants(POPs) by the World Health Organization along with polychlorinated biphenyls (PCBs), and polucyclic aromatic hydrocarbons (PAHs). According to Dr Declan Barraclough, the project manager of the UK Soil and Herbage Survey of 2007, "Dioxin concentrations in soils from urban and industrial locations are still two to three times those in rural areas. This is because dioxins are persistent in soil and act as a historical marker, reflecting emissions from industrial sites over the last 10-30 years". If this is accurate, that means we have soil samples that reflect the dioxin output of the Koppers plant over the last 10-30 years here in the heart of Gainesville.
Here's the official release:

ALACHUA COUNTY, FL - The Alachua County Health Department has reviewed the dioxin test results of six additional surface soil samples that were recently analyzed from the right-of-ways of NW 26th, 28th, 29th, 30th, 31st, and 32nd Avenues, Gainesville. The United States Environmental Protection Agency (EPA) required this additional testing approximately 300' feet west of the Koppers hazardous waste site after finding potentially hazardous levels of dioxins in the City of Gainesville easement along the site boundary. The levels of dioxins in three of the samples between NW 26th and NW 29th Avenue are above State of Florida residential standards. These additional samples indicate a continued decrease in the concentrations of dioxins from previous testing in June approximately 200' west of Koppers and in February 2009, approximately 100' west of the Koppers site in the same street right-of-ways where levels of dioxins, arsenic and benzo-a-pyrene were above state residential standards.

Incidental ingestion (swallowing) of very small amounts of dioxin contaminated surface soil at these three locations is not likely to cause harm. The Health Department continues to recommend area residents practice good general hygiene including hand washing with soap and water after contact with bare soil in areas within 300' west of the Koppers facility western boundary fence.

These test results do not affect the current Health Department Advisory. The Health Department continues to recommend that children should avoid playing in the 15'-20' City of Gainesville easement just west of the Koppers facility western boundary fence between NW 26 Avenue and NW 30 Avenue. Children under the age of six are at a higher risk of exposure from incidental ingestion (swallowing).

The Health Department will continue to evaluate the health risks as more test data becomes available.

The goal of the Alachua County Health Department is to promote, protect, maintain and improve the health and safety of all citizens and visitors.

Now if you want to ask questions and hear the details, I recommend you go to the stakeholder meeting on Monday, October 19th at the Alachua County Health Department located at 224 SE 24th St from 5:30pm-7pm. This meeting is a chance for the public to comment on the EPA Feasability Study and is happening prior to a Joint City and County Commission on October 29th whereStaff from the City of Gainesville, Gainesville Regional Utilities, Alachua County Environmental Protection Department (EPD), and the Alachua County Health Department will be presenting their findings.
