Objective:

The objective of this research project is to monitor and evaluate moisture movement and moisture balance in a bioreactor landfill operated under parallel aerobic and anaerobic conditions, something never before accomplished. Landfill leachate management can be one of the biggest challenges encountered by landfill managers. Bioreactor operation offers landfill managers the opportunity for leachate storage, treatment, and disposal. Although in situ moisture is a critical parameter to the success of bioreactor operations, it is one of the most difficult to accurately measure. This project provides an opportunity to evaluate available technology in a recirculating landfill environment.

Three primary tasks will be employed to achieve the above objectives:

1. Evaluation and Testing of Alternative Moisture Monitoring Instrumentation

in situ moisture content sensors have been developed primarily for use in the agricultural industry to monitor irrigation efficiency necessary to achieve optimum plant growth. Some of these technologies are being explored and tested for use in evaluating the moisture content in landfills. Landfills, by their nature, pose challenges to the application of these devices. Although each technology has its unique application difficulties when applied to landfills, the extreme heterogeneity of landfills as compared with farm soils creates challenges in transferring the technology to landfills. The corrosive and complex nature of the leachate also makes in situ measurements difficult.

Several devices will be installed within the head-on-the-liner-experimental area, including time domain reflectometry (TDR), neutron probes, electrical resistivity, and a variant of time domain reflectometry called frequency domain reflectometry (utilizing a microwave signal rather than a pulse). This area provides controlled leachate recirculation where head on the liner can be monitored as well as impacts from precipitation and injected moisture. Values obtained from these instruments will be compared with direct moisture measurements obtained following core sampling of the waste. The accuracy, precision, reliability, and cost effectiveness of these devices will be assessed over a 2-month period.

2. Bioreactor Moisture Input and Output Monitoring

To perform a complete moisture balance on the bioreactor, all moisture inputs (recirculated leachate and groundwater) and outputs (gas moisture and collected leachate) will be routinely monitored. The bioreactor will be capped to ensure complete control of emissions.

3. Data Analysis

Data will be analyzed to develop a moisture balance for the bioreactor. A final report will be developed summarizing results.
