Our final goals•

To review currently available data andsummarize them to find out what needs to bedone.

•To provide critical information needed toachieve Output 2 & 3.

To achieve the final goals•

Create more detailed map of the site, using
various approaches/techniques.

•Keywords: GIS / spectral data / land use / soil
and plant types / dust / water etc...

What is needed now?
• Detailed land use -> Maps– Economical evaluation, application to another place.

• Prioritize on remediation, than data collection• Soil conditioning – Effectiveness?
– Liming– Hyper-accumulator• Choosing the right crop – Education?
– High risk = leafy crops, root crops– Lower risk = fruits
