The Taanzoult plain of Aguelmam Sidi Ali wetland contains several permanent springs of water. They are intended for watering livestock, supplying drinking water and hydrotherapy. Nevertheless, the water consumption from sources in the raw state, without any pre-treatment or hygienic measures, certainly threatens the health of humans and particularly that of traditional medicine patients. From this perspective, the present work is based on a monthly monitoring of eight bacterial germs in the waters of four sources (Aghbalou Aberchane, Aghbalou Dkhiss, Aghbalou Akjdate and forestry post) during a hydrobiological cycle of 12 months from January to December 2017. The results of analyses have shown that bacterial contamination is significant at the water sources, used mainly for watering livestock, compared to those dedicated to drinking and hydrotherapy. The mean content of total coliforms and fecal coliforms at all the stations are higher than the Moroccan standards for surface water intended for the drinking water production. Except for the wet period for Aghbalou Aberchane and Aghbalou Dkhiss waters, the value of the bacterial parameters studied are higher than the Moroccan standards. In general, the anarchic frequentation of the area negatively influences the water quality and compromises its potability. Consequently, it directly threatens the health of users and hydrotherapy patients, especially during the dry season. These findings could call on the health authorities and the competent authorities responsible for controlling the quality of surface water to make users aware of the health risks and provide for appropriate arrangements to improve the quality of the widely sought-after natural waters.

The present study was conducted to better understand the specific contingency of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (E. coli) isolated from urban waters of Wadi Ouislane of the city of Meknes, compared to isolates from patients hospitalized in the resuscitation department at Mohamed V Hospital in Meknes, Morocco. These antibiotic-resistant bacteria have become ubiquitous in effluents, creating increasing concern about their potential impact on human and animal health and the environment. We took four samples of wastewater representative of a day, effluents of the wadi Ouislane. They were analyzed for indicator germs of fecal pollution, namely total coliforms (TC) and fecal coliforms (FC). Bacteria were enumerated by the dilution-filtration technique and by incorporation in solid medium in supercooling. However, four bacteriological samples, taken for clinical purposes from hospitalized patients, were performed at the medical analysis laboratory of Mohamed V Hospital in Meknes. Analysis of our results showed that ESBL-producing E. coli bacteria isolated from our effluents had the same antibiotic resistance profiles as those from hospitalized patients. Urban wastewater discharges into the environment contribute to the dissemination of extended-spectrum beta-lactamase-producing Escherichia coli that may pose health risks to the population.

The Boufekrane River is an important stream which rises west of El Hajeb (Ain Maarouf), located at 740 m above sea level, and crosses the commune of Boufekrane and the city of Meknes. This river, which is used mainly by the population of the region for irrigation and swimming, receives the discharge of raw wastewater without prior treatment. Therefore, the assessment of the quality of its water is a priority. A physico-chemical characterization of the river water was carried out during the period of March 2017 - February 2018. The descriptive analysis of the results showed that the river water undergoes significant physico-chemical variations downstream wastewater discharges, with a slight self-purification during the course of the watercourse but without reaching the initial quality noted at the source. This analysis also defined the spatio-temporal variations. The study also revealed that the average values of the quality parameters (pH, nitrite, nitrate, dissolved oxygen, Iron, chlorides, turbidity, conductivity and sulfates) of the water at the source are respectively 7.63, 0.01 mg / l, 3.47 mg / l, 5.81 mg/l, 0.14 mg/l, 115.08 mg/l, 0.48 NTU, $726.33 \\ \\mu\\mathrm{s}/\\text{cm}$ and 21.88 mg/l. They are thus below the maximum limit values for drinking water which are respectively $6.5 < \\text{pH} < 8.5, 5\\ \\hbox{`}\\leq \\mathrm{O}2\\leq 8,0.5\\ \\text{mg}/\\mathrm{l}$, 50 mg/l, 0.3 mg/l, 750 mg/l, 5 NTU, $2700\\ \\mu\\mathrm{s}/\\text{cm}$ and 400 mg/l.

1In order to improve the quality of smart city environment, health and well-being of their residents, the choice of a sustainable, economical and efficient technique adapted to the area conditions, becomes a necessity. To do this in Moroccan conditions, a pilot scale of Subsurface-vertical flow constructed wetland system (VFCW) was designed to treat domestic wastewater and his performance was investigated. This filter was planted by Chrosopogon zizanioides L. with a density of 4 plants/m2. Several water quality parameters including BOD5, COD, TSS, NH4+, NO3- and PO43- were monitored. The main treatment performance results showed the following average removal rates: BOD5 (79±13%), COD (80±11%), TSS (83±10%), NH4+(47±23%), PO43- (68±9%). The quality of the treated wastewaters was evaluated according to Moroccan Reject Limit Value (RLV).

1The Boufekrane River crosses the city of Meknes from south to north and is a place of discharge of urban wastewater. This oued is a significant source of water for irrigating vegetable crops at neighboring farms. In the absence of treatment of this wastewater, the impact on public health could not be without danger. The objective of this work is to evaluate the degree of parasitic contamination of wastewater discharging directly on the Boufekrane River and its fluctuation during the daytime. For this aim, a parasitological monitoring is carried out in the collector of "Agdal" district, located in the urban center of the city of Meknes. Samples were taken every 2 hours from 08:00 to 18:00 and processed by Arther Fizerald Fox's flotation concentration method. The results showed the presence of a variation of the parasite load during the day with a maximum observed between 12:00 and 14:00 and a minimum between 16:00 and 18:00. Twenty species have been identified. The study also showed that nematodes constituted 51% of parasite eggs followed by protozoa (35%), cestodes 11% and finally trematodes 3%.

The present study aims to develop a quality index model of spring waters (WQI-S). Based on the principal component analysis, the potential indicators were calculated. This model has been applied to determine the springs water quality of Taanzoult plain (Aguelmam Sidi Ali RAMSAR site), using physicochemical (13 parameters) and bacteriological analysis results (2 parameters), which are monitored of 4 stations during 12 months (January to December 2017). The compilation of the WQI-S allowed assessing the quality of the waters in Taanzoult plain with quality level compared to the empirical approach of the evaluation grid according to Moroccan standards. Water quality varies with the seasons and kind of use. It can be mainly considered good for spring water of drink with minimum score of 72 and good to medium with minimum score of 65 for source, exclusively, used for livestock watering. The strength of WQI-S lies in its ability to integrate a reduced parameters number deemed relevant for the assessment of water quality in each particular case. It might, therefore, maximize accuracy in determining water quality at lower cost and permit to the regulation authorities the opportunity to maximize the cost-effectiveness of water pollution monitoring missions over time.
