“…L'eau est une ressource naturelle indispensable à la vie dans tout écosystème (Tampo et al, 2015). La connaissance de sa qualité donne une vision globale des risques afin d'assurer la protection des ressources et pour déterminer les sources possibles d'altération de la qualité de l'eau (Myers., 2015), (Normatov et al,2015).…”

Surface water is subject to strong anthropogenic pressures caused by the development and extension of agricultural activities and also by industrial and domestic activities. Pollution is a serious problem for the environment due to discharges dumped into rivers and excessive use of agricultural fertilizers and discharges from urban and industrial sources. The objective of this study is to assess the quality and state of organic pollution in surface water in Upper Moulouya based on the water quality index (WQI) and the organic pollution index (IPO) during three sampling campaigns carried out between March and August of 2014. Ten stations were studied along the Moulouya and Ansegmir wadis up to the Hassan II dam. The results are visualized through the use of GIS through the production of thematic maps. They revealed that the majority of stations indicate excellent water quality and show no organic pollution with the exception of Boumia (M5) and Zaida (M6) stations which respectively have poor quality water and low pollution. at Boumia and non-drinking water

“…Nutrient monitoring in surface water dates back to at least the late 1800s when the reliability of drinking water sources for population centers became a concern (Myers, ). Then, as now, the primary monitoring approach has been infrequent discrete sample collection followed by wet chemical analysis in a laboratory.…”

Sensors and enabling technologies are becoming increasingly important tools for water quality monitoring and associated water resource management decisions. In particular, nutrient sensors are of interest because of the well-known adverse effects of nutrient enrichment on coastal hypoxia, harmful algal blooms, and impacts to human health. Accurate and timely information on nutrient concentrations and loads is integral to strategies designed to minimize risk to humans and manage the underlying drivers of water quality impairment. Using nitrate sensors as the primary example, we highlight the types of applications in freshwater and coastal environments that are likely to benefit from continuous, real-time nutrient data. The concurrent emergence of new tools to integrate, manage, and share large datasets is critical to the successful use of nutrient sensors and has made it possible for the field of continuous monitoring to rapidly move forward. We highlight several near-term opportunities for federal agencies, as well as the broader scientific and management community, that will help accelerate sensor development, build and leverage sites within a national network, and develop open data standards and data management protocols that are key to realizing the benefits of a largescale, integrated monitoring network. Investing in these opportunities will provide new information to guide management and policies designed to protect and restore our nation's water resources.(KEY TERMS: sensors; nutrients; water quality; information management.)

“…A revolution in water-chemistry analysis took place with the development of advanced physical instrumentation that began in the 1930s.. This affected water analysis in three ways: (1) new types of analytical instruments expanded the ability to detect a wide variety of chemical compounds using small amounts of sample; (2) the time needed for analysis was reduced and precise measurements became possible; and (3) with each passing decade from 1930 to 1975, the detection capabilities of new analytical instruments improved by about an order of magnitude or more (Travis, 2002;Myers, 2015). Detection limits decreased from tens of milligrams per liter in 1890 to tenths of micrograms per liter by 1950.…”
