What We Do
- Site Characterization & Mitigation
Our team thoroughly understands the process of developing an understanding of the geologic, hydrologic and engineering properties at a site, including the soil, rock, along with groundwater and conditions in the subsurface, such as utilities, structures, mines or tunnels. This includes assessment of contaminants when present. In addition, we offset known impacts to existing historic or natural resources, such as a stream, wetland, endangered species, or archeological site.
- Remedial Design & Actions
LDS partners with clients to design specifications for cleanup remedies and technologies, and then implement remedial action following the design phase. This can involve actual construction or implementation phases of Superfund site cleanup.
- Radiological Surveys
Our team works with clients to plan, implement, and evaluate environmental and facility radiological surveys conducted to demonstrate compliance with a dose- or risk-based regulation. Our focus is on compliance during the final status survey following scoping, characterization, and any necessary remedial actions.
- Demolition, Environmental & Levee Repair
The LDS team understands the science and engineering in safely and efficiently tearing down buildings and other structures. This can sometimes include environmental treatment of chemical, biological, or thermal wastes, purification of water and air, and remediation of contaminated sites. Our experts also provide thorough periodic inspections and evaluations on levees conditions and threats; maintaining and repairing levees to sustain integrity and reduce flood risk; maintaining levees to protect, restore, and enhance environmental resources, and supporting environmentally-compatible improvements, to minimize costs to operate and maintain a flood control system
LDS’ team of experienced professionals work to recover ecosystems that have been degraded, damaged, or destroyed.
