•— Harmonisation of water sampling points, networks,
parameters and frequencies for water quality monitoring in order to meet, with minimum work at field
level, the needs linked with EU Directives, OECD-Eurostat
Questionnaires, EEA Eurowaternet”, Marine and River Conventions, and
local/regional needs.
•— Assessment of point and diffuse losses of
nutrients to waters, and of the breakdown of
their origin (agriculture, urban waters, industry,
air deposition…:
•— Models
correlating environmental impacts (e.g. algae blooms) and causative
factors
(nutrients, natural conditions, etc.), which will allow forecast of
impact of various scenarios in the reduction or increase of these
factors.
•— Cost-efficiency approach for preventive measures. Nitrogen and Phosphorus will certainly
appear as priority polluters in many E.U. watersheds.
