leachate generation

Leachate generation is a direct result of precipitation.

Although largely stabilised from a biological viewpoint with a much reduced potential for gas and leachate generation, the residues cannot be considered inert. 110.

The purpose of the cap is to limit the ingress of water to the waste material fill, thereby limiting leachate generation.

Leachate generation will occur throughout the landfill's operational phase and continue into the aftercare phase, long after waste disposal at the site stops.

In the case of landfills, EPA may require proper capping to reduce leachate generation and pollution of ground water.

Rising leachate levels can also wet waste masses that have previously been dry, triggering further active decomposition and leachate generation.

In particular, I am developing models to predict leachate generation and mobility from coal-based waste deposits including coal stockpiles and ash deposits.

A Conceptual Risk-Based Approach to Leachate Generation from Hazardous Waste Deposits.

Composting on a large scale removes a significant portion of the organic waste stream from landfill disposal which otherwise contributes to leachate generation and increased landfill gas production.

Both cells showed the importance of unsaturated flow mechanisms in controlling the water balance and leachate generation, due mainly to the potential of ash to retain moisture in its pores.

Deterministic models of leachate generation and mobility for granular minerals processing waste are being developed to assist in the prediction of long term environmental liability associated with waste disposal practices.

Because the entire processing operation is enclosed with a building (as opposed to open air windrow composting), there is no contamination of stormwater, no significant odour and no leachate generation (from the compost heaps).

The risks of leachate generation can be mitigated by properly designed and engineered landfill sites, such as those that are constructed on geologically impermeable materials or sites that use impermeable liners made of geomembranes or engineered clay.

Cameco’s preferred decommissioning plan for the B-zone waste-rock pile is to grade and vegetate it; however, Cameco indicated that, if modelling predicted an unacceptable impact on water quality of the B-zone pit, it would examine cover options to reduce infiltration and leachate generation.
