This study assessed the impact of the X-740 Phytoremediation System, located at the Portsmouth Gaseous Diffusion Plant, on a TCE plume. Differences in planting technique and tree species used at the site were analyzed. In addition, groundwater uptake and TCE removal were determined. The X-740 Phytoremediation System was planted in 1999 and was calculated over the following years. The phytoremediation system was initially expected to take two years to reach maturity, however, the groundwater data presented in this paper documents that actually it was four years before the phytoremediation system began noticeably influencing the groundwater. The phytoremediation system does not show a decrease in water elevations until 2003, even though it was expected to have occurred in 2001 or 2002. Increased hydraulic gradient across the site indicates by 2005 the system trees were extracting 75,000 gallons per day (gpd) or 98 gpd per tree. The total mass of TCE in the phytoremediation area in 1999 was 425 g when compared to 2005 the TCE mass was 394 g showing a slight decrease particularity in the final two years of sampling. Furthermore, the TCE concentration is demonstrating fluctuating results. During the growing season the TCE concentrations are lower than during the dormant season. This occurrence is also evident in the byproducts of TCE consistently from 2001 through 2005. BIOCHLOR simulations also indicate that the TCE concentrations are below what would be expected due to natural attenuation. The results of this evaluation indicate that the trees are having a positive effect on the groundwater at the X-740 Area, although the effect is slight and not apparent until the fourth year of growing. It is expected that TCE contaminant and removal will continue to improve as the trees mature.
