Project objectives:
In 2000 NICOLE set up a data sharing programme for industrial sites to investigate the possibilities for MNA. Over four years eight industrial partners made 
investigations as part of this demonstration project. Summary site reports were reviewed by twelve independent reviewers. In general MNA was viewed as applicable
and effective at many sites. The proposed methodology with the three common lines of evidence was considered very useful. Differences of opinion from reviewers
of different nationalities were marked. The results and final report of this project were presented at the NICOLE meeting in Sardinia in December 2005.
Project Summary:
The eight cases investigated are representative for European industry. Most cases were complex, with layered hydrology and multiple contaminants and/or 
phases present. The outcomes of the site assessments were not known beforehand, but all sites (in consultation with the authorities) were looking to fit MNA
into a risk based site approach, either as a stand alone option or a cost-effective addition to active source measures. Each reviewer reviewed two sites; each site was reviewed three times. Most reviewers recognized the occurrence of NA, but at times felt uncertain (25%),
indicating a need for more information than that offered in the summary reports. (The original site reports were summarized to aid reviewing. It was unrealistic
to expect reviewers to review all the underlying reports and data).
