Geochemical assessment of environmental health in the shoreline between Nador and Al Hoceima, North East of Morocco

The Ghiss-Nekor aquifer, located in the north-east of the action area of the ABHL, plays a strategic role in the drinkable water supply of the city of Al Hoceima and of the neighboring urban areas. It also participates in the irrigation of PMH. However, this aquifer has problems such as over-exploitation and pollution. In the face of these problems, the only Solution is the establishment of a new mode of governance, which privileges the participation, the involvement and the responsibility of the actors concerned in a negotiated contractual framework, namely the aquifer contract. The purpose of this study is to diagnose the current state of the Ghiss Nekor aquifer, the hydrogeological characterization of the aquifer, the use of the waters of the aquifer, the Problem identification and the introduction of the aquifer contract, which aims at the participatory and sustainable management of underground water resources in the Ghiss- Nekor plain, to ensure sustainable development.

The City

In the North East of the Moroccan Mediterranean coast, 15 km south east of the Al Hoceima city, the coastal aquifer of Ghiss-Nekkour occupies an area of 100 km2. Its exploitation constitutes a priority economic imperative for the city of Al Hoceima and its hinterland, due to the tourist character of the city and the agricultural orientation of the region. In the surface of this study area, alternate rural-type habitats with autonomous sanitation systems, agricultural plots, uncultivated land, a few small industrial units, a local road network, in addition to the International Airport Charif El Idrissi. These are various potential sources of local anthropogenic groundwater contamination. Their intensity may grow with the socio-economic development that knows the region as a whole. In this work, the authors apply a new multicriteria approach of acronym “PRK Plus” to assess the sensitivity of the coastal aquifer Ghiss-Nekkour to anthropogenic pollution. The results obtained from this application show that despite the aggressiveness of the Ghiss-Nekkour groundwater pollution sources, 98% of the total surface area of the water table is “very little sensitive” to anthropogenic contamination.

General Aspects

Electron microscopy (EM), with the advent of computer control and image analysis techniques, is rapidly evolving from an interpretative science into a quantitative technique. Electron microscopy is potentially of value in two general aspects of environmental health: exposure and diagnosis.In diagnosis, electron microscopy is essentially an extension of optical microscopy. The goal is to characterize cellular changes induced by external agents. The external agent could be any foreign material, chemicals, or even stress. The use of electron microscopy as a diagnostic tool is well- developed, but computer-controlled electron microscopy (CCEM) has had only limited impact, mainly because it is fairly new and many institutions lack the resources to acquire the capability. In addition, major contributions to diagnosis will come from CCEM only when image analysis (IA) and processing algorithms are developed which allow the morphological and textural changes recognized by experienced medical practioners to be quantified. The application of IA techniques to compare cellular structure is still in a primitive state.

The City

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.
