  • Areas Where Revetment Mats Can Provide Structure and Ground Stability

    First things first—what does the term revetment mean in relation to erosion control? Well, revetments are like sloping walls placed just right to block or drain invading water before it can destroy a surrounding ground, like riverbanks, beaches, cliffs and man-made waterways. Containing articulated concrete, a revetment mat installation—consisting of one or more pieces—is the ...

  • The Importance of Dewatering

    With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game.  Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control ...

  • How Not to Lose Cadmium While Measuring?

    Today cadmium finds a better usage than a hundred years ago. For example, metal cadmium plating is used for anticorrosion coatings that are more stable than zinc, nickel and tin-plated. Cadmium plating of steel parts gives greater resistance to corrosion, especially in sea water. About 20% of cadmium goes to the manufacture of cadmium electrodes used in ...

  • A grid for subgrade stability

    With research to back up quantifiable benefits and recognized design standards, the use of geogrids may be ready for wider acceptance among North American railroads. A product with a 20-year plus track record is rarely referred to as "new." However, this is a label those involved with geogrids find themselves tagged with when it comes to the prod¬uct's use on North American railroads. While ...

  • In Situ Solidification/Stabilization

    Introduction Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their 'host' medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical or ...

  • Metals Stabilization Using Geochemical Fixation

    Introduction To Chemical Fixation There are several approaches to treatment of chromium and other toxic metals such as lead arsenic, and cadmium in soil and groundwater, including isolation, immobilization, toxicity reduction, physical separation, and extraction (U.S. EPA. 2002). Brief Overview Of Metals Remediation Methods: Conventional ...

  • Stabilization of intermodal and port facilities overview - Case Study

    THE Geoweb® LOAD SUPPORT system Constant weight of parked trailers, stacked containers and heavy traffic patterns can cause your intermodal or port facility yard’s surface and subbase materials to degrade. Ruts, potholes, and even pavement failure are often the result of instability in or failure of the base materials. These surface problems can require continual, costly ...

  • In situ biogeochemical stabilization (ISBS) technology for source area

    Non-aqueous phase liquids (NAPLs) and other hydrocarbon residuals can represent long-termsources of ground water plume constituents of interest (COIs). Excavation and disposal oftenrepresents the most rapid, cost-efficient and effective means of removing these sourcematerials from the environment. In many cases, however, these types of remedial actions arenot possible / cost effective hence in ...


  • Laboratory Testing Apparatus for Slopes Stabilized by Anchored Geosynthetics

    A laboratory testing apparatus is described for examining slopes subjected to seepage and stabilized by anchored geosynthetics (AGS). The AGS technique can increase the stability of cohesionless slopes such as coastal dunes against surficial erosion and shallow mass failure caused by wave action and seepage forces. In the AGS, a geosynthetic fabric is placed on the face of the slope and tensioned ...

  • Satellite-based estimation of atmospheric stability parameters in urban and remote areas

    A methodology is presented which can be used to determine atmospheric stability parameters in urban and remote areas where ground-based meteorological observations are not routinely available. The method resolves the surface energy balance by means of satellite remote sensing in an original way. Ground-based data from the FIFE experiment are used to validate parts of the methodology. Results are ...

  • Control Algae and Improve the Water Quality in Waste Stabilization Ponds

    Due to population growth, accelerated urbanisation and economic development, the quantity of waste water generated is increasing globally. Mainly in low-income areas, a large proportion of the waste water is discharged directly in the environment. When the waste water is treated, the treatment plants may not remove certain pollutants that can have a negative impact on the people and ecosystem. ...

  • Use of Lime Stabilized Biosolids for Turf Grass Production in the New Jersey Pinelands

    A 700 acre farm producing turf grass sod for residential and commercial uses has been utilizing liquid, lime stabilized biosolids as its primary source of plant macronutrients on approximately 380 acres since late 1995. The farm is located within the New Jersey Pinelands, a sensitive and unique ecosystem characterized by pine-oak forests, sandy soils and high quality ground and surface waters. ...

  • Common Treatment Technologies for Inorganics in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate inorganics in ground water, surface water, and leachate. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be particularly important to characterize the effects of adsorption and other processes of ...
