Once the landfill is constructed, BLE continues to provide services to ensure that the facility remains stable and compliant. We commonly provide consultation of waste placement for stability including “sliver” fills, evaluation of interim waste slope stability and evaluation of special wastes on landfill stability. Proper construction of perimeter sliver waste fills helps to capture airspace after settlement causes flattening of the waste slopes. BLE provides analysis and construction recommendations for haul roads across the waste mound. We can also provide slope monitoring and stabilization recommendations if needed.
In addition, our team will oversee the removal of stormwater berms (rainflaps) to confirm the integrity of the geomembrane liner and we can also provide soil management evaluation and recommendations for “best-use” of available on-site soils. Soils suitable for low permeability compact liners or free draining soils for drainage layers can be identified and quantified during a borrow study.
Other services we provide include:
Environmental Data Validation and Remediation
Landfills are designed to minimize contamination leakage through liner systems, leachate collection, and caps; however, contamination impacts do occur to the underlying soils, groundwater or surface waters. BLE is experienced and understands the unique challenges and issues involved to remediate landfills.
An Assessment of Corrective Measures lays out technologies and/or processes to mitigate environmental contamination. Remedial action objectives typically focus on groundwater impacts, landfill gas (LFG), and leachate releases to stormwater and waters of the State. However, from a practicable standpoint, remedial actions must be reasonably achievable, implementable, constructible and effective, and may require a multidisciplinary team with cross-functional solutions.
Remedial alternatives can present various technical challenges, ranging from:
BLE’s team of engineers, geologists and technicians provide the following closure services:
