  • Treatability study of bioremediation of dinitrotoluene

    Dinitrotoluene (DNT) ground water contamination at the Propellant Burning Ground has been controlled by a pump and treat system since 1990. Alternative approaches to improve the cost effectiveness are under evaluation, including reducing the amount of ground water extraction by treating contaminants in place. Bioremediation has been evaluated and shown to be effective, but required an engineered ...

  • Quarry management in Spain

    Ecological restoration criteria in degraded areas as a result of mining activities call for the reutilisation of the tailings themselves. These materials do not meet the necessary fertility conditions to guarantee the success of the restoration and therefore require organic amendments to obtain an efficient substratum. Deficiencies in the organic material and nutrients of the restoration material ...


  • Pesticides persist in groundwater, say SSSA

    Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations. The downward movement of pesticide degradation products, formed in situ, can also contribute to the contamination of ground water. Once in ground water, pesticides and ...

  • Bench-Scale Study Provides Insight Into PCE and TCE Aerobic Cometabolism

    CL Solutions completed a bench-scale test of aerobic cometabolism of PCE and TCE in contaminated ground water.  The purpose of the pilot study was to confirm applicability of aerobic cometabolism to a hazardous waste release site.  Additional testing was undertaken to provide insight into the aerobic cometabolic pathway.  The pilot study included treated and untreated ...

  • Aerobic cometabolism of tetrachloroethylene (PCE)

    Tetrachloroethylene (PCE) is a problem contaminant because of its widespread use, potential toxicity and persistence in the environment. Like other chlorinated solvents, remediation of PCE in soil and ground water has proven to be very difficult. While there has been has been widespread success under anaerobic conditions, the application of bioremediation under aerobic conditions has not been as ...

  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...
