Lakeshore Environmental, Inc. (LEI) was contracted to determine the feasibility of converting an existing sand mine into a LEED residential and commercial development utilizing sustainable concepts. Conceptual planning involved a review of zoning documents, an evaluation of potential environmental concerns, and a renewable energy use assessment. Based on the findings from the conceptual planning, recommendations were made identifying three alternative land-use plans, which incorporated wind, solar and geothermal energy applications, LEED residential and commercial structures, native landscaping, previous surface features, and sustainable sewer and water supply systems.
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.
Lakeshore Environmental, Inc. (LEI) performed a wetland investigation of 1,850 acres of property owned by a nearby county. Activities involved a review of available state and federal information, an on-Site review of topography, vegetation and soils, and indicators of wetland hydrology. The investigation was consistent with state and federal guidelines. Based on the presence of wetland areas at several locations across the Site, LEI provided recommendations for future land-use planning.
