Bill, You might contact David J. Butcher, Professor of Chemistry, Department of Chemistry and Physics, Western Carolina University, email [EMAIL PROTECTED], about their study on Phytoremediation on Lead and Arsenic at Barber Orchard. They found that Indian Mustard is the best species for lead phytoremediation and that brake ferns are the most suitable for arsenic. They are currently conducting biotechnological experiments to find more solutions.

Bill, Jack Hale is knows about phyto-remediation of soil and was involved ( brain please function) in a test project about two years ago with some pretty polluted soil. Hopefully his computer is on and he'll get back to you fairly soon. Best wishes, Adam Honigman -----Original Message----- From: Honigman, Adam [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 02, 2002 4:58 PM To: 'Bill Maynard' Cc: '[EMAIL PROTECTED]' Subject: RE: [cg] soils testing on urban lots Bill, $700 seems a trifle too dear... Here is the website for the Soil and Plant Tissue Testing Laboratory at theUniversity of Massachussets - Amherst. They do a great US $ 8.00 soil test (per sample) which includes all heavy metals. They also do a very complex test for every nutrient known to man for $12 a sample. Garden coordinators from all over the midwest and northeastern US use them for price, speed and accuracy. If you have something particularly tricky, I'm sure that they do it, and for less that $700 a sample. http://www.umass.edu/plsoils/soiltest/ -----Original Message----- From: Bill Maynard [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 02, 2002 4:39 PM To: '[EMAIL PROTECTED]' Subject: [cg] soils testing on urban lots What you don't know ...might hurt you.... As our 30 year old Mandella com garden site in sacramento has recently found out: "some areas with higher than acceptable levels of Lead, DDT, and PAH'S(polyaromatic Hydrocarbons left from the incomplete burning of gas, coal, etc) were found." The levels of lead that sacramento county deems acceptable is under 200 parts per million (some professionals say 80 is the highest lead should be)... this site had 500 to 1300 parts per million....plus other toxins the site had older homes from the 1860's on it before it was torn down back in the 1960's the garden started in the 1970's....apparently no testing was done.... As I understand it...the complete palette of soil tests (lead, heavy metals, PCB's, PAH's, etc, etc) costs $700 per sample (many sites would require 12 or more samples.... Question 1: are there any places that will do all these tests for free or low cost for us community gardeners? Question 2: How many urban gardens have had their soil tested for lead and other toxins? and what levels did they find? this will be a big issue in the sacramento area and will be the first HIGH hurdle for each new com garden in the area. (we have approx 6 CG's proposed in various stages in the long approval process) In the mean time.... Each garden should ask itself: was the lot built on before? Answer: Your local USDA office will have old aerial photos of your area back to the 1930's and other photos taken every 10 years or so to the present...
