EXCEPTIONALLY LONG MTBE PLUMES OF THE PAST HAVE GREATLY DIMINISHED
McDade, J.M., J.A. Connor, S.M. Paquette, and J.M. Small.
Groundwater, Vol 53 No 4, 515-524, 2015
Studies published in the late 1990s and early 2000s identified the presence of exceptionally long MTBE plumes (>2,000 ft) in groundwater, cited in technical literature as characteristic of MTBE plumes. To investigate the subsequent behavior and fate of these MTBE plumes over the past decade, reviewers compiled recent groundwater monitoring records for nine historical MTBE groundwater plumes whose lengths formerly ranged from 2,700 ft to 10,500 ft in length. Groundwater monitoring data compiled in this review show that these large MTBE plumes decreased in length over the past decade, with five of the nine plumes exhibiting decreases of 75% or more compared to their historical maximum lengths. MTBE concentrations within these plumes declined by 93-100%, with two of the nine sites showing such significant decreases (98% and 99%) that the regulatory authority found the sites require no further action.
