Abstract SYMPHOS 2011

key pollutants including heavy metals, pesticides, PAHs, VOCs and other inorganic and organic pollutants.
In some countries or regions there is a sanitation fee, in which is described that the amount payable is based on the
pollutant characterization on each company, so that the more polluter pays the higher sanitation fees.
Other Industrial Water Controls are done for monitoring the water supply (potable water, industrial waters,
refrigeration waters, etc.) or to control Legionella in risk installations, such as cooling towers, showers, etc.
INSPECTION AND ANALYSIS ACTIVITIES
To manage wastewater control works in Spain it is mandatory to have the Title of “Collaborating Entity of Water
Administration” issued by the Ministry of Environment that assumes that the company holds the ISO 17020
accreditation for inspection activities and ISO 17025 accreditation for laboratory assays activities.
The sampling and inspection activities are so important as assays activities, because with an inspection improperly
done, the analysis results of the wastewater control are not valid. The same happens with an analysis run out
without quality control or inappropriate technology to analyze samples.
To design a water inspection program it is important to know the discharge authorization data or details or the
legislation applied (parameters, limits, sampling type, frequency, etc.), the sampling point and the company
characteristics (activity, timetable, wastewater treatment, etc.).
NEW POLLUTANTS
In addition of the traditional wastewater monitoring, which involves physical-chemical and microbiological
parameters, in Europe new Regulations and Directives are appearing with environmental quality standards for
priority substances and other pollutants with the aim of achieving good surface water chemical status (Directive
2008/105/CE) or for the European Pollutant Release and Transfer Register (E-PRTR) (Regulation Nº 166/2006).
These Regulations and Directives include substances like Tributyltin, Chloro-alkanes C10-C13, Octylphenols and
Octylphenols, Di-(2-ethyl hexyl) phthalate (DEHP), Brominated diphenylethers, Metals, Pesticides, VOCs, PAHs, etc.
These analyses require high specialized laboratories in water control.

L’Afrique du nord et le moyen Orient renferment près de 86% des réserves en minerais de phosphates du globe,
estimées à environs 65 milliards de tonnes, dont 76,9 % sont concentrées au Maroc [1]. La majorité de ces gisements
sédimentaires est située dans des zones semi-arides ou arides où la problématique de la rareté de l’eau se pose
de façon accrue. L’exploitation optimale de ces ressources minières, nécessaire aux développements économique
et social de ces pays, rend indispensable la valorisation de niveaux phosphatés de plus en plus pauvres, à fortes
teneurs en argiles et en impuretés carbonatées et/ou siliceuses. Ces derniers nécessitent donc un enrichissement
