A comprehensive environmental investigation of an active artillery range

Abstract

AbstractThe Michigan Department of Military Affairs (MDMA) recently completed an environmental investigation of the 27,000‐acre Range 40 artillery and air‐to‐ground complex located at the Camp Grayling Army National Guard Training Site. The study, commenced in 1992 as part of a consent order agreement between the MDMA and state regulators, is an extensive five‐phase investigation designed to measure effects to the environment as a result of over 50 years of military training at this state owned and operated installation. Conducted under a $2.2 million contract awarded to QST Environmental, Inc. (formerly Environmental Science & Engineering, Inc.), this investigation‐commonly referred to as the “Range 40 Study”‐focused on groundwater, surface waters, wetlands, soils, sediments, and fish in and around the 7,000‐acre “impact” area situated in the central northern region of Michigan's lower peninsula.Findings indicate that surface waters (lakes and streams), lake and stream sediments, groundwater, fisheries, and air quality have not been adversely impacted by explosive‐related chemicals. Findings do indicate the presence of low levels of metals in soils, lake and stream sediments, and groundwater. During the workplan process and subsequent investigations, results were obtained and lessons learned that could have implications on national defense readiness and environmental sustainability. This article will present these results and lessons learned, including: Sustaining defense readiness through thegeneration and use of defendable scientific data. Maintaining the training mission while protecting the environment and promoting sustainable range management. Examples include reconfiguration of ranges, realignment of white phosphorous firing boxes, and recycling of excess propellants. The importance of an open dialogue with regulators, contractors, milita y trainers, local environmental interest groups, and citizens in preparation of sound workplans. The incorporation of data such as historical use of ranges, soil and geological characteristics, and geographical features in determining an installation's potential for commencing a comprehensive study or sustainable range management plan. Establishment of reliable statistically based background values. Advantages of a phased methodology investigation. Development of a long‐term groundwater monitoring plan.
