  • Solar energy landfill caps

    Things weren’t going well at the Erewhon Landfill. It was time to close the facility, and there was no soil left onsite for construction of the cap. Erewhon was a County facility, and the money available for 30 years of post-closure gas monitoring, groundwater sampling and reporting, erosion repairs and maintenance of a grass cover was sorely needed elsewhere. The landfill manager recalled ...

  • Low Flow Groundwater Sampling Using RotaPump Inertial Lift Pump

    This article tells you how to perform low flow groundwater sampling using a portable, surface-mounted pump with no decontamination required before each use and  no chance of cross contamination between wells. An inertial lift pump moves a dedicated (stored in the well) pumping tube rapidly up and down.  A one-way valve on the bottom admits water on the down stroke and ...

  • Wet water v. paper water: water management under the 1980 Arizona groundwater code.

    The Arizona Groundwater Management Code was enacted in 1980 to address the trend of widespread groundwater depletion across the State. The Code limits withdrawals of groundwater within designated areas (known as Active Management Areas or AMAs) to holders of groundwater rights, service area rights, groundwater withdrawal permits, and small domestic water users. Each AMA is required to maintain a ...

  • GW monitoring in saxony

    Background During the hundred-year flood in 2002 in Eastern Germany the river “Elbe“ and a lot of rivers in the catchment area exceeded the banks and caused damages of millions within a short period of time. Often unnoticed, the groundwater level was rising extremely after a certain time. The time of rising groundwater took considerably longer than the actual flood, and caused enormous ...

  • Field Demonstration of a Permeable Bioreactive Barrier for Leachate Control.

    ABSTRACT: A biostimulation technique was selected for a pilot study to treat groundwater at a former New Jersey municipal landfill. The process will address a mixture of chlorinated compounds (e.g. vinyl chloride and chlorobenzene), hydrocarbons (e.g. benzene and methyl ethyl ketone) and heavy metals. The reactive barrier will be constructed using a series of injection points to implace a slurry ...

  • Adsorption of fluoride from aqueous solution using low cost adsorbent

    High fluoride levels beyond the recommended value of 1.5 mg/L have been detected in several groundwater wells in Northern Ghana. This occurrence has led to the capping of many high yielding wells that hitherto have been major sources of drinking water for the populace in these arid areas. Most of the fluoride removal technologies applied in the area has not been versatile in effectively removing ...

  • Use of Mathematical Models to Evaluate Management Options for Reducing PCB Bioaccumulation by Fish in Two Streams at the Neal`s Landfill Site, Bloomington, IN

    ABSTRACTNeal’s Landfill received PCB-containing wastes that originated from a Westinghouse Plant in Bloomington, IN. PCBs have been transported to the groundwater beneath the site and into two nearby streams: Conard’s Branch and Richland Creek, and consequently, PCBs have impacted the water, sediments, and fish of these streams. Remedial actions conducted at the site have included removal of ...

  • Landfill Leachate Sources and Treatment Options

    What is leachate? In a lab, it is any liquid that extracts solids as it passes through matter. In a landfill, it is the water that enters the facility in a number of ways, passes through waste material on contact, contains a wide range of constituents, and must be addressed with a proper operations plan. Leachate treatment options and mitigation are one of the greatest costs for landfill ...
