  • Soil Sampling under Buildings and Solving Vapor Intrusion using Horizontal Drilling

    The Issue: The New Jersey Department of Environmental Protection (NJDEP) mandated soil and groundwater sampling under an active pharmaceutical company manufacturing building in order to address vapor intrusion inside the building. Installation of vertical borings and wells through the building slab was not practicable without profound disruption of manufacturing activities inside the building. ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
