  • Using Electromagnetic induction to characterize soils - Case Study

    Electrical conductivity measurements have been used for years to determine salinity and moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a ...

  • Use of Electromagnetic Induction Tools in salinity assessment/appraisals in eastern Colorado

    Abstract Electromagnetic induction (EMI) is a relatively low-cost and rapid method for measuring, assessing spatially soil salinity. The two studies were conducted to evaluate data obtained with a single-frequency (EM38 meter) and multi-frequency (GEM300 sensor) EMI instruments and to relate apparent conductivity measured by these instruments with the more conventional conductivity of the ...

  • GoForth, NC Case Study

    ABSTRACT Trap & Treat® BOS 200® was used to remediate petroleum hydrocarbon impacted groundwater within fractured bedrock and overburden soil at a former retail gasoline site in North Carolina. After a thorough remedial design characterization was completed, BOS 200® was surgically injected over two field events to successfully achieve the ...

  • Characterisation of septage in partially sealed cesspit

    The alteration of wastewater from an individual home under anaerobic conditions in a partially sealed cesspit over the filling period of four months, and the pollution fluxes were assessed. The septage was much more concentrated than raw wastewater. A mass balance found percentage (%) removal rates for biological oxygen demand (BOD5, 78%), chemical oxygen demand (COD, 62%), total nitrogen (TN, ...

    Rothamsted Research, a leading agricultural research institution, is attempting to make data from long-term experiments available to all. In partnership with a data consultancy, is it developing a method to make complex results accessible and useable. The institution is a member of the Godan Initiative that aims to make data available to the scientific community. In ...

  • Identification of groundwater contamination zone around a reclaimed landfill using carbon isotopes

    Chemical and isotopic analyses of groundwater from piezometers localized around a reclaimed landfill were performed in order to identify the boundaries of groundwater contamination zone. Spatial distribution of dissolved inorganic carbon (DIC) concentration and stable carbon isotopes in the groundwater was used to distinguish the piezometers localized within the contaminated aquifer. Background ...

  • How To Complete A Soil Test The Right Way

    A soil test should be one of the first steps you take in your landscape plan. Many of us never take this important first step, which contributes, to wasted resources and wasted time. The U.S. Department of Agriculture says soil testing is an “essential” tool that provides information on fertility and pH. Testing also indicates ...

  • Knowledge, attitudes and practices on use of Fossa Alternas and double vault urine diverting dry (DVUDD) latrines in Malawi

    Fossa Alternas and double vault urine diverting dry (DVUDD) latrines have been extensively promoted as ecological sanitation (EcoSan) latrine options in Malawi, but little is known about whether they are used properly. A qualitative study of EcoSan users was conducted in Blantyre and Chikwawa districts, Malawi. Data were collected using in-depth interviews (IDIs). Twenty-eight (28) and ...

  • Should Your Sensor Have A Connector Or Pin Terminals?

    When it comes to measuring the activity of your project, it’s nice to have options. High precision sensors can offer plenty of selections from the range of your measurements to the output of your readings, but a sensor is only as good at its connection. Connectors and pin terminals are common and dependable connections that relay your readings from within the sensor to the screen in front ...

  • Sustainable groundwater modeling using single- and multi-objective optimization algorithms

    This study presents the first attempt to link the multi-algorithm genetically adaptive search method (AMALGAM) with a groundwater model to define pumping rates within a well distributed set of Pareto solutions. The pumping rates along with three minimization objectives, i.e. minimizing shortage affected by the failure to supply, modified shortage index and minimization of extent of drawdown ...

  • Phosphate treatment by onsite wastewater systems in nutrient-sensitive watersheds of North Carolina's Piedmont

    The goal of this study was to gain a better understanding of the PO4-P treatment efficiency of onsite wastewater systems (OWS) installed in nutrient-sensitive watersheds of the North Carolina Piedmont. Four OWS including two conventional and two single-pass sand filter (SF) systems were evaluated at sites with clay-rich soils. Piezometers were installed near all of the OWS, and down-gradient ...

  • Calibration of a capacitance soil sensor is required to achieve the level of accuracy required for satellite ground truthing

    Why not make it easy with a non-capacitance based soil sensor like the HydraProbe? This study published in American Meteorological Society's BAMS journal demonstrates the extent of variability in readings one can expect with a soil moisture sensor based on capacitance technology.  To ...

  • Case Study - Evaluating Geothermal Potential - Ravenna, Italy

    University of Bologna researchers carried out an investigation of the thermal properties of the coastal aquifer at Ravenna Italy in order to evaluate its geothermal potential for residential heating. As part of that investigation, they measured the water temperature versus depth at 56 piezometers. EnviroInsite was then utilized to establish the relationship of water temperature with land use, ...

  • Soil Retention at Village of Moreland Hills, Ohio - Case Study

    PROJECT SCOPE: The village of Moreland Hills, Ohio faced a challenge to re-tain soils in a problematic soft soil area. But, piling systems were expensive and a concrete solution in the natural environment was undesirable. Presto GEOWEB® earth retention system’s inherent qualities include its flexibility, ability to withstand reasonable differential settlement in soft soil environ-ments, ...

  • An evaluation of inorganic toxicity reference values for use in assessing hazards to American robins (Turdus migratorius)

    When performing screening level and baseline risk assessments, assessors usually compare estimated exposures of wildlife receptor species to toxicity reference values (TRVs). We modeled the exposure of American robins (Turdus migratorius) to ten elements (As, Cd, Cr, Cu, Hg, Mn, Pb, Se, Zn and V) in spring and early summer, a time when earthworms are preferred prey. We calculated soil ...
