  • Using a Digital Cone Penetrometer to Locate Clandestine Grave Sites

    Abstract Law enforcement officials face the problem of locating suspected burial sites connected to criminal activity. Two case studies describe the collection of soil compaction data and subsequent analysis to locate a test burial at a research site. Forensic scientists use the RockWorks software from RockWare, Inc. to analyze the data and display three-dimensional views of the relative ...

  • Liquid and Plastic Limits as Determined from the Fall Cone and the Casagrande Methods

    The shortcomings of the conventional methods of determining the liquid limit using the Casagrande apparatus and the plastic limit by rolling soil balls by hand have led to the investigation of the fall cone (cone penetrometer) as an alternative. The use of the fall cone test to determine the liquid limit has long been adopted by several countries, but the proposal to use this test to determine ...

  • Studies with Centrifuge Vane and Penetrometer Apparatus in a Normal Gravity Field

    Small vane and penetrometer devices have been developed to measure soil properties in models during centrifuge operation. To aid the interpretation of vane data from centrifuge models a series of tests was conducted in cakes of kaolin clay in a normal gravity field. In the experimental program the effects of disturbance during insertion, delay between insertion and rotation, rate of rotation and ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • 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 ...

  • Phytoremediation - II

    Introduction: Phytoremediation is a set of processes that uses plants to clean contamination in ground water and surface water. There are several ways plants can be used for the phytoremediation. These mechanisms include enhanced rhizosphere biodegradation, hydraulic control, phyto-degradation and phyto-volatilization. Enhanced Rhizosphere Biodegradation Enhanced ...

  • Inland oil spill clean up case study

    Introduction The essential strategy for inland spill clean up techniques should be containment, recovery and temporary storage. Secondary needs will include transportation and possible disposal - or recycling. It is important to discover the source of the spill which might not be straight forward. A steady slow seepage from a leaking disused oil storage tank may be very difficult ...
