Arnott Fen Groundwater Monitoring Project

Borton-Lawson performed groundwater monitoring services of the Arnott Fen wetland and adjacent stream located within the right of way of the Susquehanna to Roseland 500-kV Transmission Line Project and the Delaware Water Gap National Recreational Area in Bushkill, Monroe County, Pennsylvania.

The monthly monitoring of this globally rare wetland complex was conducted to identify potential impacts to groundwater and several endangered species that utilize the wetland as a habitat as a result of the installation of an adjacent new tower structure within the project right of way.

Challenges V. Solutions

Challenge Proposed project was located adjacent to a complex wetland system within the Delaware Water Gap Natural Recreation Area lands. Borton-Lawson needed to identify potential direct hydrologic impacts to groundwater within a globally-rare wetland system and indirect impacts to several endangered species due to the installation of an adjacent new tower structure within the project right of way.

SolutionDeveloped an acceptable monitoring approach that satisfied the National Recreation Area concerns by protecting the wetland system. Borton-Lawson conducted monthly groundwater monitoring of several monitoring wells during the pre/post and construction periods to identify potential changes in hydrologic conditions. Report findings to the Owner and National Park Service for documentation to ensure ongoing monitoring and protection of these sensitive environmental resources.
