We have a thorough, expert assessment service that draws on our knowledge of aerobic and anaerobic degradation processes, landfill gas and leachate generation, biological treatment processes, hydrogeology and air quality. These services include:

• Landfill gas and hydrogeological risk assessments employing specialist software tools GasSim2 and LandSim;

• Nuisance and health risk assessments of dust, odour and bioaerosols including odour modelling

• Atmospheric dispersion modelling using ISC-AERMOD and DMRB (v.11) for point, area and line sources of emissions to air

• Management plans for landfill gas, leachate, odour, surface water

• Water balance calculations and leachate feasibility studies

• Site Protection and Monitoring Plans (SPMP), Pollution Inventories (PI), H1 Risk Assessments and DSEAR assessments.

All Egniol technicians are fully trained and qualified and all sample analysis is carried out by a UKAS accredited laboratory.

Data Management

Understanding the data supplied by the specialist software used in environmental monitoring is a highly developed skill in itself.

Our analysts manage and monitor the database information supplied by systems such as MonitorPro and MS Access for several clients and provide detailed quarterly and annual reports in accordance with Environment Agency guidance and client requirements.

Landfill Gas Extraction

Our background in landfill gas extraction makes Egniol something of a leading authority on the technology and logistics of gas extraction. We have assisted clients in the design of bespoke extraction systems and provided third party audits and reporting in gas pumping trials.
