Purpose of Project

The site is an agricultural experiment station farm with residual levels of DDE from routine historical DDT application. I have been running field trials over the last 10 years as part of a research program on the potential phytoremediation of persistent organic pollutants like DDE/DDT. Zucchini and pumpkin were identified as plants that can accumulate significantly greater quantities of DDE in their roots and stems than other plants. Anecdotally, the highest soil DDE level in 2000 was 1ppm; this last field season, the highest level I could find was 0.4ppm.
