Mengfang is an experienced hydrogeologist and groundwater modeller and has applied groundwater flow and contaminant transport models to manage groundwater resources, quantify river-aquifer interaction, and evaluate remedial alternatives and conduct cost and benefit analyses for numerous sites in UK, Europe, Mid East and China. He is Royal Haskoning’s Technical Director of Hydrogeology and Contaminated Land and a Chartered Geologist of the Geological Society.He was a technical advisor and technical lead for Olympic Delivery Authority for groundwater and contaminated land and has supervised the development of groundwater model and technical guidance for conducting human health and groundwater risk assessment for London 2012 Olympic Park. Other key projects involved were Thames Water funded project ‘Hydrogeology and Hydrochemistry of London Basin’, Severn Trent Water ‘Cryptosporidium Hydrogeological Risk Assessment’; BNFL ‘Environmental Assessment Programme for Sellafield Nuclear Power Station’ and British Energy 'Environmental Impact Assessment for New Build Power Stations' Mengfang has constructed and calibrated numerous multi-layer groundwater flow and contaminant transport models incorporating river-aquifer interactions using MODFLOW, MT3DMS and RT3D with GWVistas and Visual MODFLOW.Mengfang assisted in developing and validating CLEA2000 for DEFRA and the Environment Agency, and routinely provides training course on RBCA and CLEA model to the UK contaminated land industry focusing on the application of RBCA as an alternative model to CLEA V1.04 and the Environment Agency Remedial Target Worksheet.
Mengfang has recently developed alternative integration procedures, which would speed up the process for the derivation of GAC/SGV if implemented with CLEA model.
Mengfang is a regular speaker at Annual Brownfield Briefing Risk Assessment Conference and founding chairman of UK Chinese Association for Environment and Resources (UK-CARE).
