Water In Ecosystems: A Non Renewable Resource
This project involves close collaboration of specialists in various disciplines (e.g.
agronomy, hydrology, biology, chemistry, socio-economy, information technologies).
IS MAP started in September 1991 by a Definition Phase aimed at a
comprehensive state-of-the-art review and at technical specifications of the
planned developments. Phase 2 started in October 1993 and is expected to be
completed early in 1997 with intermediate operational results. The program of
work in Phase 2 is presented below.

ISMAP DEVELOPMENT PROGRAM
4.1 Pesticide detection and field water quality
measurements
ISMAP is currently identifying, developing and validating multi-residue analytical
methods for pesticide detection that could be routinely used with greater
efficiency and adequate reliability. A preliminary selection of about twenty
pesticides was established for investigation; this selection is based on application
quantities, dispersion potential, toxicological and ecotoxicological data and
referenced contamination cases.
In addition, ISMAP will address the problem of analysis quality insurance and will
try to establish evaluation criteria for laboratories involved in water quality
analysis.
ISMAP involves partners with different (even apparently competing) interests in
agricultural pollution concerns. Prepared for cooperation by several months of
collaborative work, this group intends to contribute to preparing standards and
regulations at national and European levels.
4.2 Water treatment procedures
Based on the priority list of pesticides established for analysis, water treatability
tests are being developed and validated through laboratory experiments on pilot
facilities and in water treatment plants.
Seven treatability tests were identified in the Definition Phase and have already
been tested in the laboratory: coagulation-flocculation, biodegradation, stripping,
photolyze, adsorption on activated carbon, oxydation with or without hydrogen
peroxyde.
A collection of technical documents describing the behaviour of each pesticide
and the performance and efficiency of treatment procedures for each pesticide will
be established. A knowledge base is being set up in order to support treatment
plant operators in selecting and implementing appropriate water treatment
procedures.
