Currently he is teaching Hydrology in Xavier University - Ateneo de Cagayan in the Philippines and is also free lance consultant on groundwater modeling.

As you may know, the Secretariat of the Sustainable Sanitation Alliance is currently in the process of finalising a factsheet book. The factsheet book will comprise of 13 thematic factsheets. We would therefore like to invite you to discuss and give further input to the factsheet of WG 11. We would be delighted if we could receive further input for the factsheet as soon as possible so that we could have a final version and print the book. We would like to print the book end of November.

Some general suggestions are:

• differentiate between small shallow wells without distribution system and deepwells with a distribution system.
• for which one would SuZanA be most urgent and applicable?
• more attention to "traditional" micro-pollutants, like benzene (from fuel), organic solvents (industry, dry cleaners) and PCB, DDT, ...

Attached you will find the document with Jan's input. Please use the document attached when providing your comments.

I look very much forward to your feedback! It would be preferable if you could upload your comments and input here in the discussion forum. That way, more members can contribute and discuss any open questions left before finalising. However, If you would like to send your feedback directly to the SuSanA secretariat, please email to: This email address is being protected from spambots.
