A simple method to check for natural attenuation downstream of abandoned waste disposal sites

Evaluations of waste sites are based on the assessment of whether conditions for Natural Attenuation (NA) processes are favourable. A method is proposed as a first check for effects of NA in the groundwater emissions. For the application of the method, concentrations of the concerned substance and of a tracer must be available at observation wells at different distances from the source, preferably along a flowpath of the waste site. The method is demonstrated at waste sites, with TOC as proxy for a degradable component. The method can be recommended within a priority programme for NA-remediation on landfills.

    The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the derogation that allows Air Pollution Control residues to be disposed of to landfill at three times the standard waste acceptance criteria (3xWAC) threshold for hazardous landfill. Chief technical officer, David Deegan, explains why below: The waste...

  • Tire Shredding: Alternatives to Landfills

    For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires can float like balloons to the surface, sometimes rupturing the protective liners that keep contaminants from polluting...

  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt production, landfills face more challenges in fighting odors. Moisture, humidity, agitation, and summer temperature can...
