Environmental studies conducted by Lytle Water Solutions personnel have typically involved the identification, characterization and then remediation of various surface and ground water contamination issues. Effective remediation of surface and ground water contamination requires an initial characterization of the magnitude and spatial extent of the problem, design of a remedial action plan, approval of the plan by the appropriate regulatory agency and implementation of the plan. LWS personnel have been involved in all of these aspects of environmental studies. Representative projects are described below.
Ground Water Remediation in Alluvial Aquifers
Approximately 1400 T. of liquid fertilizer was lost from a storage tank in Fremont, Nebraska and infiltrated into a shallow alluvial aquifer. A monitoring well system was designed and installed to characterize the extent of the contamination; a remedial action plan was developed, approved and implemented.
A leak from a gasoline storage tank in Albany, New York resulted in ground water contamination. The tank was situated on dredged materials adjacent to a river that created complex geologic conditions. In addition, local tidal influences produced daily changes in ground water gradients which changed the magnitude and direction of ground water flow. As a result of these conditions, the contamination was contained in a relatively small area. A remedial action plan was designed, approved and implemented and has now been successfully completed.
Environmental Baseline Studies
LWS staff have designed and implemented baseline environmental monitoring programs in connection with mine permitting, power plant licensing, and for compliance monitoring at facilities in California, Colorado, Florida, New York, North Dakota, Pennsylvania and Wyoming.
Environmental Due Diligence – Phase I Assessments and Phase II Investigations
LWS personnel have performed hundreds of Phase I environmental site assessments (ESAs) and Phase II subsurface investigations across the United States. Key LWS Senior Project Managers are extremely experienced with property acquisitions, divestitures, and lease scenarios for industrial, commercial, and agricultural properties. We have routinely performed projects under the confidentiality requirements of attorney-client privileged information. We are intimately familiar with the ASTM E1527 Standards for conducting Phase I and II assessments. Our clients’ needs and project types vary; therefore, there can be different levels of scrutiny from a screening/professional opinion to a full ASTM-compliant Phase I ESA. Our expertise in conducting these assessments allows us to approach our client’s particular needs in an efficient and cost-effective manner.
Purchase of an ammonia terminal in an industrial area near Joliet, Illinois, was pending; so an environmental audit was conducted to assess potential environmental liabilities associated with the purchase. Monitoring wells were installed to evaluate both contamination on-site and contamination that could be migrating on-site from adjacent industrial facilities. The results of the study were used in the evaluation of the purchase of the property.
Environmental Project Management
LWS personnel have many years experience in managing environmental assessment and corrective action remediation projects. LWS personnel have managed many multi-site Phase I assessments that involved teams of assessors working simultaneously across the country to satisfy our client’s schedule. We have contracted with licensed, and insured, parties to perform underground storage tank removals, dig-and-haul projects, and remediation system installation and operations.
LWS personnel understand varying EPA, State, and local regulatory requirements, and we have assisted clients with negotiating cleanup goals, monitoring, and regulatory reporting. Our broad understanding of environmental projects from beginning to end allows us to characterize contaminant impacts, evaluate potential contamination receptors, and prepare risk-based corrective action plans.
Environmental Assessments/Pro-Active Remediation
An historic zinc-processing facility in Sauget, Illinois wanted to understand its environmental liability. A monitoring well and sampling program was designed and implemented to characterize the environmental issues. Based on the results of the initial environmental assessment, a voluntary remediation program was then designed and implemented to reduce metals input to the local alluvial aquifer.
Tracking Spills in an Alluvial Aquifer
There was a gasoline tanker that overturned near one of the Parker Water and Sanitation District's alluvial production wells in Colorado. Monitoring was set up to insure that no gasoline migrated to the potable water supply well while the spill area was being remediated. The integrity of the potable water supply well was protected through the monitoring and clean-up program.
