Description

The Large Lakes and Rivers Research Station in Grosse Ile, Michigan, is part of EPA's Mid-Continent Ecology Division (MED) in Duluth, Minnesota, and operates under the Office of Research and Development (ORD). The goal of the Grosse Ile laboratory is to develop methods to predict and assess the effects of pollutants and polluting activities on freshwater ecological resources.

Unique Environmental Features

Energy Conservation

The Large Lakes Research Branch completed installation of a direct digital control facility management system, which is expected to help reduce energy consumption at the facility through enhanced monitoring and controls.

Green Power

EPA offsets 100 percent of the electricity consumption at the Large Lakes and Rivers Research Station with renewable energy certificates (RECs) purchased through the Agency's current blanket green power contract. Learn more about EPA's current and past blanket green power contracts.
In June 2004, EPA entered into a three-year contract with 3 Phases Energy Services to purchase 700,000 kWh annually of green power in the form of RECs for the Grosse Ile laboratory, which represented 100 percent of the facility's electricity use. This contract supported the generation of renewable energy at a landfill gas facility in Lenox, Michigan.

Water Conservation

In August 2007, EPA completed a water management plan for the Large Lakes and Rivers Research Station (PDF) (16 pp, 465K, About PDF).
The Grosse Ile facility maintains an aggressive program to identify and respond to leaks. A screening level system review was completed in July 2007, and known water uses account for more than 90 percent of water consumption. Facility staff are trained to reports leaks and malfunctioning water-using equipment to the on-site facilities manager designee. The facility also makes use of an automatic leak detection system, based on conductivity bridges (“water bugs”) placed on the floor adjacent to water-using equipment.
The facility uses minimal landscape irrigation water. Across most of the three-acre site, grasses and shrubs are climate-suitable and survive on natural rainfall. Hand watering is limited and only applied to keep plants from dying off during dry conditions. In FY 2007, the laboratory began to evaluate a potential option to divert rainwater from a roof drain and store it in a cistern in the basement of the main laboratory building, then use it for landscape irrigation.
