A large metropolitan hotel owner pursued Lakeshore Environmental, Inc. (LEI) for the purpose of conducting a subsurface investigation that will ultimately lead to a No Further Action letter from the Michigan Department of Environmental Quality. LEI has developed a plan to create a Conceptual Site Model that will establish the existing Site conditions. Once the model is completed, LEI will conduct the appropriate investigation activities necessary to define the extent of soil and groundwater contamination and mitigate potential unacceptable exposures. Tasks associated with this project will include numerous soil borings, installation of monitoring wells, soil and groundwater sampling, a vapor intrusion assessment, preparation of restrictive covenants, a groundwater mixing zone evaluation, groundwater modeling, and reporting.
Lakeshore Environmental, Inc. (LEI) in collaboration with the City of Muskegon Heights,successfully obtained a $200,000 grant form the Michigan Department of Environmental Quality (DEQ) to assist in the expansion of a medical facility. The expansion required the acquisition and redevelopment of a contaminated property formerly utilized as an auto repair and sales shop.
Environmental activities completed by LEI included the following: soil and groundwater sampling; completion of a Phase I ESA, Phase II Investigation, Baseline Environmental Assessment, and Due Care Plan; supervision of contaminated soil and hoist removal; removal of an abandoned underground storage tank; asbestos and lead-paint surveys; and oversight of building demolition activities.
Lakeshore Environmental, Inc. (LEI) was awarded a research grant from the National Ground Water Research and Educational Foundation to conduct an assessment of groundwater age and rate of recharge using environmental tracers. The goal of the grant project was to determine the sustainability of groundwater use at a specific Muskegon County location.
LEI installed numerous shallow and deep nested monitoring wells at a large property for the purpose of collecting groundwater samples for laboratory analysis of chlorofluorocarbon (CFC)-11, -12, and -113 parameters – key groundwater age indicators. During recharge, water picks up a CFC signature based on the atmospheric concentration of CFCs, and groundwater retains its characteristic CFC concentration.
Laboratory analytical results indicated that the groundwater age in the shallow wells ranged from 21 years to 43 years and the groundwater age for the deep wells was approximately 58 years. The topographic and hydraulic gradients, groundwater elevation data, and laboratory data indicate that the younger, shallow water mixes with the deeper older groundwater near the point of discharge.
The results of this research could aid in creating sustainable development concepts and decrease disruption to the aquifer recharge and the natural interaction of the groundwater/surface water interface. Based on the results of this study, LEI has been retained by two businesses to assess whether their processes involving groundwater usage is sustainable. This interest supports the growing concern for a sustainable water supply for current and future generations.
Lakeshore Environmental, Inc. (LEI) conducted a Phase I ESA at a commercial nursery and identified stained soils and the former presence of two underground storage tanks (USTs) on the Site. To address these recognized environmental conditions, LEI completed an extensive Phase II Investigation to assess the condition of the soils and groundwater. Significant gasoline-related soil and groundwater contamination was identified in the vicinity of the former USTs. Corrective action activities to remediate the contamination involved excavation and disposal of nearly 350 tons of impacted soil; the design, construction, and operation of an air sparge/soil vapor extraction system; and the recovery of approximately 5,000 gallons of free product.
