Ecological Revitalization Case Studies - The Atlas Tack Site and the Poudre River Site - August 2. This seminar will focus on two case studies where ecological revitalization principles have been put into practice. At the Atlas Tack Superfund site, adjacent fresh and salt water wetlands were heavily contaminated by discharge and fill of metal plating and enameling waste emanating from the site. The site is situated approximately 500 m northwest of Buzzards Bay, designated as an Estuary of National Significance. Ecological enhancement was used as part of waste site remediation. At the Poudre River Site, polycyclic aromatic hydrocarbons have been observed in the soils of a former gas plant, in the groundwater underneath a closed landfill, and in the sediments of the Poudre River itself. The cleanup and protection of the Poudre River involves such intricacies as the creation of a barrier wall, the redirection and treatment of contaminated ground water, and the replacement of non-native vegetation with native species.

Long-Term Monitoring Optimization (LTMO) Training, August 7-8, Boston. EPA is partnering with the U.S. Army Corps of Engineers to provide state and federal regulators with information about new methods of optimizing groundwater monitoring programs. The training will be held at the EPA Region 1 Office. Responsible parties, federal facilities, and EPA have used LTMO methods at more than 100 sites nationwide and are likely to use them at more sites in the future. The methods are used to support decision making regarding optimal location and frequency of groundwater monitoring and to support changes to existing monitoring networks. As a result, it is important for regulators to be familiar with LTMO methods and technical support mechanisms such that appropriate decisions can be made. The training includes a 1-day lecture on a variety of qualitative and quantitative methods including: the Monitoring and Remediation Optimization System (MAROS); the Geostatistical Temporal-Spatial (GTS) algorithm; and the Three-Tiered Monitoring Network Optimization (MNO) approach. Two 4-hour hands-on training sessions with the MAROS software program will be offered on the second day for a limited number of attendees. While the training is designed primarily for state and federal regulators, federal facilities cleanup managers, potentially responsible parties (PRPs), and contractors are welcome to participate at no cost. State and federal regulators will receive registration priority. For details about this training and to register, visit
