Kansas Location Lindsay James Contact Service Lines GroundwaterDue Diligence Project Understanding Blackstone completes investigation, monitoring and remediation for the Kansas Petroleum Storage Tank Release Trust Funds. The Storage Tank Trust Funds are designed to provide financial assistance to owners and operators of facilities where contamination from petroleum storage tanks has occurred. Services Provided Monitoring: Blackstone completes routine groundwater monitoring at approximately 45 petroleum release sites for the Kansas Department of Health and Environment (KDHE) Trust Fund groundwater monitoring program. Blackstone samples the groundwater at each facility on a semi-annual or quarterly basis for contaminants of concern, assesses the condition of the monitoring wells, and prepares a report detailing the results following each event. Monitoring is conducted to obtain and develop sufficient data so that potential risk to the environment and human health can be evaluated. Based on the results of the monitoring, Blackstone makes recommendations regarding future work at each facility. Investigation: Blackstone has completed Limited Site Assessments for the Gardner-Cenex and Belle Stop facilities.…

Kansas Location Kyle Kukuk Contact Service Lines GroundwaterSolid Waste Project Summary Blackstone provides environmental compliance and engineering services to the Coffey County Sanitary Landfill (CCSL). The CCSL is an approximate 38-acre municipal solid waste landfill (MSW) located near Burlington, Kansas, and operated by Coffey County. Services Provided Blackstone assists the landfill with groundwater monitoring and also provides engineering design services, construction quality assurance for liner and cap construction, and test pad permeability (Boutwell) testing. Blackstone also prepared a design report for a proposed phytoremediation pilot test plot unit. The pilot test plot was designed to evaluate using CCSL leachate for beneficial use as an irrigation source on native, water-loving trees and grasses, which will utilize the evapotranspiration process to naturally treat the landfill leachate. The pilot test plot goal is to determine the viability of using diluted leachate as an irrigation source and to evaluate the interaction between the native vegetation and the leachate to ultimately determine maximum loading rates for a larger, permanent phytoremediation…

Missouri Location Lindsay James Contact Service Lines GroundwaterSolid Waste Geology & Hydrogeology Project Understanding Blackstone provides routine groundwater monitoring and compliance services for the City of St. Joseph Sanitary Landfill and the closed McArthur Drive Landfill. Blackstone has assisted the City with cell Construction Quality Assurance (CQA), Erosion Control Plan preparation, Cap and Closure services, installation of a nested perimeter probe gas monitoring system, landfill rate study, stormwater compliance, GCCS system repairs, and airspace calculations. Services Provided Blackstone provides routine semi-annual groundwater monitoring and statistical evaluation for the St. Joseph Sanitary Landfill and annual monitoring of groundwater, sediment, and surface water for the closed McArthur Drive Landfill. Non-routine groundwater services have included investigation of VOC detections in groundwater; preparation of sampling and analysis plans; background statistical updates; hydrogeological site characterization activities; investigation of fluctuating water levels in multiple monitoring wells using downhole camera inspection; and installation of replacement monitoring wells. Blackstone completed oversight and installation of a complex site-wide nested perimeter gas probe monitoring system…

Iowa, Kansas Location Emily Smart Contact Service Lines Due DiligenceGroundwater Geology & Hydrogeology Project Summary Blackstone provided pre-purchase review of environmental databases, imagery, site reconnaissance, soil and groundwater sampling, and geotechnical engineering exploration of Casey’s General Store properties ranging from active gas stations to agricultural fields. The objectives of the PPAs were to conduct site reconnaissance and data research for the site and adjacent properties to determine if any factors are present that may have a negative impact on the environmental integrity of the site; and to conduct a limited subsurface investigation (LSI) to determine if petroleum hydrocarbons have been released or spilled into the soils or groundwater underlying the site prior to the potential purchase by Casey’s General Stores. Geotechnical evaluation is also included in order to determine viability of soils for planned construction activities in order to predict project costs. Services Provided Site history and database review prior to mobilizationSite reconnaissanceMinimum one environmental boring per sitePID screening, log borehole, sample soil as appropriateSample…
