July Webinar: Surveyor’s Role in Contaminated Land Investigation and Remediation

Friday 06 July, 10am - 11am

Assessment of contamination on a property relies on locating objects and activities that may have caused contamination. Historic aerial photographs are an important tool that can help the contaminated land practitioner identify objects and activities that may have caused contamination.

The hard part is setting out the contaminated areas on the property with its current layout. Sheds present in the 1940’s, yards with a potential sheep-dip removed in the 1960’s, a waste-burning area present only in the 1970’s are just a few examples. Most contaminated land practitioners are not well equipped to locate these potentially contaminated areas caused by historical land use. Using the old survey plans, topographic maps with different projection and declination is clearly in the realm of the surveyor.

Cooperation between the contaminated land practitioner and the surveyor is essential for an effective and correct site assessment, and an important step towards successful remediation. This webinar will present a few examples of how crucial the surveyor’s input has been to the success of the detailed and further site investigation.

Many of his projects have entailed R&D and often outcomes have been shared with colleagues through courses, workshops, publications or conference presentations.

    Ben studied Physics and Hydrogeology in Amsterdam. He holds 1st class Honours Doctoral Degree in Hydrogeology specialising in Isotope Hydrochemistry. He is a Fellow of the Royal Society of Chemistry, a Member of the Royal Society of NZ and a full member of the Institute of Directors NZ. In February 2016, Ben completed an Executive MBA at Massey University with his final thesis on the National Economic Impact of Lead Contamination in the Home Environment. Between '94 - '04 Ben was one of the four Accredited Environmental Auditors in the Grand Dûche of Luxembourg.

    In Shell International Ben held organisational roles from being in charge of all petroleum engineering aspects at drilling and production platforms to reservoir engineering team leader for Northern North Sea fields.

    Ben started the first company in New Zealand specialising in soil and groundwater assessment and remediation in 1988. He investigated over half of the oil terminals in New Zealand ports. This was followed by the assessment and remediation of hundreds of service stations and depots in Australia.

    Since 2005 Ben has conducted several audit reports for regional councils in New Zealand, such as Environment Waikato. He also carried out peer reviews and validation studies for several regional councils, including the Greater Wellington Regional Council.

    Ben has completed over 320 NES reports since the introduction of the NESCL on 1-1-2012. He is the author of several major reports for Ministry for the Environment (MfE) on brominated flame retardants and chemicals in E-waste (available on the MfE website); he has edited the MfE guidelines for local councils on Sheep-dips and the MfE Handbook on Natural Attenuation of Petroleum Hydrocarbons.
