Knowledge, perception, and attitude toward premarital screening among university students in Kurdistan region–Iraq

Premarital screening programs are essential for identifying and providing counseling to couples at risk of transmitting genetic diseases or sexually transmitted infections. Despite their importance, university students’ awareness and knowledge of premarital screening programs remain inadequate. This study aimed to evaluate the knowledge, perceptions, and attitudes of university students in the Kurdistan Region of Iraq regarding premarital screening programs. A cross-sectional survey involving 960 students was conducted from December 2023 to February 2024. The survey assessed participants’ demographics, knowledge, perception, and attitudes toward PMSP using a structured questionnaire. Findings revealed that a significant portion of participants (39.4%) had poor knowledge of premarital screening programs, 35.9% had fair knowledge, and only 24.7% had good knowledge. Despite limited knowledge, there was strong support for premarital screening programs, with 83.1% agreeing on its importance and 78.8% recognizing the need for premarital awareness. Most participants (65.8%) believed premarital screening programs could reduce genetic diseases, and 65.6% thought it could lower sexually transmitted diseases’ prevalence. Cultural acceptance of marrying relatives was notable, with 59.7% disagreeing with the preference for not marrying relatives. Married participants showed significantly higher knowledge and attitude scores compared to single participants. Gender differences were observed, with males having higher knowledge scores. There were no significant differences in perception and attitude scores based on gender or residential area. The study underscores the need for enhanced educational campaigns to improve premarital screening programs awareness and positively influence attitudes, especially targeting cultural aspects like accepting relative marriages. Comprehensive education and fostering positive attitudes toward premarital screening programs are vital for their broader acceptance and implementation.

Three Years of Google Earth Engine-Based Archaeological Surveys in Iraqi Kurdistan: Results from the Ground

This paper presents the results of a three-year survey (2021–2023), conducted in an area of approximately 356 km2 in Iraqi Kurdistan with the aim of identifying previously undetected archaeological sites. Thanks to the development of a multi-temporal approach based on open multispectral satellite data, greater effectiveness was achieved for the recognition of archaeological sites when compared to the use of single archival or freely accessible satellite images, which are typically employed in archaeological research. In particular, the Google Earth Engine services allowed for the efficient utilization of cloud computing resources to handle hundreds of remote sensing images. Using different datasets, namely Landsat 5, Landsat 7 and Sentinel-2, several products were obtained by processing entire stacks of images acquired at different epochs, thus minimizing the adverse effects on site visibility caused by vegetation, crops and cloud coverage and permitting an effective visual inspection and site recognition. Furthermore, spectral signature analysis of every potential site complemented the method. The developed approach was tested on areas that belong to the Land of Nineveh Archaeological Project (LoNAP) and the Upper Greater Zab Archaeological Reconnaissance (UGZAR) project, which had been intensively surveyed in the recent past. This represented an additional challenge to the method, as the most visible and extensive sites (tells) had already been detected. Three years of direct ground-truthing in the field enabled assessment of the outcomes of the remote sensing-based analysis, discovering more than 60 previously undetected sites and confirming the utility of the method for archaeological research in the area of Northern Mesopotamia.

Association of Oral Manifestations with Iron Deficiency Anemia: A Case-Control Study

Insufficient iron levels cause oral signs of iron insufficiency. Iron is necessary for several biological activities, including oral tissue health. Low iron levels might alter oral tissues, causing particular symptoms. The aim of this study to detect the oral manifestations of iron deficiency anemia as well as to investigate the link between the severity of these manifestations and the degree of the iron deficiency. The study includes 100 patients with iron deficiency anemia at an Azadi Teaching Hospital, in Duhok City, North of Iraq, and 98 healthy persons. A full history was obtained, and complete blood count and serum ferritin were recorded. In terms of gender distribution, a clear dominance of females was observed, as they represented 94% of the total cases compared to only 6% for males. Regarding the severity of anemia, most patients had moderate to mild degrees, while severe anemia cases represented a smaller percentage (12%). The comparison between patients and healthy people showed highly significant statistical differences in all pathological changes of the oral mucosa. Complete absence of pathological changes was more common in healthy controls (85%) than in patients (34%). Some pathological changes were closely associated with iron deficiency anemia, such as atrophic glossitis and angular cheilitis. This study concludes by highlighting the strong correlation between iron deficiency anemia (IDA) and oral mucosal lesions, and the most common oral manifestations are present in patients with severe iron deficiency anemia.

A NEW CONJUGATE GRADIENT METHOD BASED ON LOGISTIC MAPPING FOR UNCONSTRAINED OPTIMIZATION AND ITS APPLICATION IN REGRESSION ANALYSIS

The study tackles the critical need for efficient optimization techniques in unconstrained optimization problems, where conventional techniques often suffer from slow and inefficient convergence. There is still a need for algorithms that strike a balance between computational efficiency and robustness, despite advancements in gradient-based techniques. This work introduces a novel conjugate gradient algorithm based on the logistic mapping formula. As part of the methodology, descent conditions are established, and the suggested algorithm's global convergence properties are thoroughly examined. Comprehensive numerical experiments are used for empirical validation, and the new algorithm is compared to the Polak-Ribière-Polyak (PRP) algorithm. The suggested approach performs better than the PR algorithm, according to the results, and is more efficient since it needs fewer function evaluations and iterations to reach convergence. Furthermore, the usefulness of the suggested approach is demonstrated by its actual use in regression analysis, notably in the modelling of population estimates for the Kurdistan Region of Iraq. In contrast to conventional least squares techniques, the method maintains low relative error rates while producing accurate predictions. All things considered, this study presents the novel conjugate gradient algorithm as an effective tool for handling challenging optimisation problems in both theoretical and real-world contexts.

The use of autonomy among physical education teachers in Finland and Kurdistan region of Iraq

IntroductionThe aim of the study was to examine fifth-grade physical education (PE) teachers’ reflections and perceptions about PE teaching in Finland and Kurdistan region of Iraq (KRI), using analyses of in-depth interviews with a phenomenological-hermeneutic approach.MethodsThis was accomplished by exploring eight Finnish and six KRI PE teachers’ opinions, attitudes, experiences, and reflections regarding their work as PE teachers, using semi-structured in-depth interviews about PE, as well as their reflections related to an indoor and an outdoor video from ordinary PE teaching in the other country. The initial analyses of the two groups of teachers using the qualitative analysis program NVivo revealed interesting findings related to student autonomy, and these differences were examined closely.ResultsWhile the analyses showed that all the Finnish PE teachers highlighted the importance of providing student autonomy within the open-ended questions related to PE, PE teachers in KRI seldom discussed autonomy during the open-ended questions. Instead, they seemed to organize their teaching in a way that decreased autonomy. The Finnish PE teachers indicated that the use of autonomy was central in the curriculum, and that they used autonomy to increase the students’ motivation and to make PE more meaningful for the students. With such a strategy, the use of autonomy would also activate and include more students, even if Finnish PE teachers reported certain challenges with students’ autonomy. The PE teachers from KRI, however, related PE to be mainly focused on performing sport activities and reflected a strategy of “just do as I do” - a strategy that created little room for autonomy, even if the findings pointed to some traces of autonomy among the PE teachers in KRI.DiscussionConsidering the findings and the theoretical concept of self-determination theory that highlight students’ autonomy as essential for students’ motivation, integration, wellness, and well-being in PE, our findings suggest that new perspectives and practices are needed among teachers in KRI to ensure autonomy in PE teaching. In this vein, increased exchange of experiences and collaboration between educators from Finland and KRI could be beneficial.

Outcomes of Congenital Heart Diseases in Duhok, Kurdistan Region of Iraq

Background: Congenital heart diseases (CHD) are the most common birth defects worldwide, significantly impacting morbidity and mortality, especially in low- and middle-income countries where early diagnosis and access to surgical care are limited. In Iraq, congenital heart surgeries are relatively new, and few studies have investigated CHD outcomes in this context. Aim: This study aimed to evaluate the prevalence, distribution, and surgical outcomes of congenital heart diseases among patients treated at the Azadi Heart Center in Duhok, Kurdistan Region of Iraq. Patients and Methods: A retrospective, cross-sectional study was conducted involving 111 patients aged 1-69 years with CHD who underwent surgery at the Azadi Heart Center between March 2019 and March 2024. Data were collected on demographic characteristics, clinical profiles, surgical details, and postoperative complications, including mortality rates. Statistical analysis was performed using Microsoft Excel, with data presented as means, standard deviations, frequencies, and percentages. Results: The average age of patients in the study was 13 years (±16), with congenital heart disease (CHD) being most common among children, who made up 80.18% of cases. Male patients accounted for 54.95%. The most frequent CHD types observed were Tetralogy of Fallot (25%), isolated Ventricular Septal Defect (20%), and Atrial Septal Defect (10%). The surgeries were highly successful, with a 95.5% success rate. However, some patients experienced postoperative complications, such as pneumonia (11.71%), arrhythmias (10.96%), and surgical site infections (5.41%). The overall mortality rate was 10.81%, with infections being a leading cause of death after surgery. Conclusions: CHD is prevalent among young patients in Duhok, with favorable surgical outcomes and acceptable complication rates. These findings highlight the need for early detection, enhanced surgical resources, and continued surveillance to improve outcomes for CHD patients in Iraq.

Exploration of Bituminous Materials Using 2D Electrical Resistivity Imaging, Kurdistan Region, NE Iraq

Solid bituminous materials are widely spread in the Iraqi Kurdistan Region, they are filled so many locations, such as fracture zones, fault planes, and bedding planes. These materials can be used in several industries like pavement road, roofing, bituminous paint and waterproof, etc. The study aims to find an economical quantity of these materials by using 2D resistivity imaging in three locations that are different in geology and tectonic settings. These locations are Alla Syaw, Mera De, and Nasalih villages. The data are collected using Syscal R1 plus resistivity meter, for the sake of following up horizontal and vertical extension of these materials Wenner-Schlumberger array is used with 72 electrodes and a spacing interval of 5 m. Three profiles were conducted for each location, which have lengths equal to 360 m. The data processing was carried out by using the RES2DINV, and the smoothness was performed using finite difference forward modeling. The results show that all the bituminous materials are detected in shallow depths and only in the sandstone layers of the Tanjero, Gercus, and Injana formations filling the fracture zones and fault planes. This is also attributed to the more brittle behavior of the sandstone layer than other layers of these formations which deforms easily by applying external stresses. In the Tanjero Formation bituminous body is detected at a depth of about 10 m, which has an extension of more than 50 m from profile-1 to profile-2 (this is a lateral extension). The average width and height of the body are about 8m and 20 m, so it forms an approximate total volume equal to 8000 m3. The study concludes that the preliminary estimation of the total volume of the detected bituminous bodies is about 20000 m3, which has great importance as raw material for different industries. The bituminous material has a high resistivity value in most of the profiles reaching more than 200 ohm.m.

Source Rock Evaluation and Hydrocarbon Generation Potential of the Cretaceous (Dokan and Gulneri) Formations in Bai Hassan-13 Well Section, Kurdistan, North of Iraq

Eleven cutting rock samples from both Dokan and Gulneri formations (Cretaceous) in one subsurface section of Bai Hassan-13 (BH-13) well in northern Iraq were studied by using two techniques for hydrocarbon generation potentiality. The geochemical technique included Rock-Eval Pyrolysis analysis, The optical technique was achieved by studying palynological slides. The rock-Eval pyrolysis results showed that Dokan Formation has total organic carbon (TOC) wt.% ranging between 1.16 % and 2.3 % (good to very good), Gulneri Formation has a high TOC of 1.34 % and 4.64 % (good to excellent) quantity of organic matter. About the quality of organic matter, both Dokan and Gulneri formations are composed of kerogen types I and II. The organic matter of the Dokan Formation is not indigenous (migrated), one sample of the Gulneri Formation is indigenous the other one is located on the slanted line separating the Indigenous from non-indigenous organic matter. The organic matter within the two formations are thermally immature source rock, Therefore, they cannot generate oil and gas. The palynological study revealed that amorphous organic matter is the predominant organic matter component in both formations with more than 89%, whereas phytoclasts and palynomorphs comprised only a few percentages. There is no great variation in the percentages of the mentioned organic matter components, except a slight increase in the percentage of phytoclasts and palynomorphs in the lower part of the Dokan Formation, therefore one primary palynofacies type can be recognized, and divided into two secondary palynofacies. Through plotting Tyson's Amorphous, phytoclasts, and palynomorphs (APP) diagram, it is clear that the two formations are deposited in a distal suboxic to anoxic basin.

Implementing an adaptive reuse on industrial buildings: a proposal for transforming Erbil’s Silo in Kurdistan-Iraq into a hotel

Industrial buildings, serving as markers of cultural heritage, connect our cultural identity from the past through the present and into the future. Unfortunately, many of these buildings lose their identity when they are converted into another function. Through the case study analysis (the Silo of Erbil City), a qualitative method is employed to examine design strategies and spatial transformations in recent adaptive reuse projects of existing structures. Through the literature review, this research investigates the importance of adaptive reuse and heritage buildings, underscoring their historical and theoretical underpinnings, and subsequently examines contemporary approaches to architectural criteria towards habitation for existing structures in the public, creative, and cultural domains. The study findings identify common fundamental elements of industrial heritage adaptive reuse and innovative design strategies applied in recent adaptive reuse projects, highlighting the potential to transform neglected or vacant abandoned buildings into urban open spaces. The study uses a comprehensive methodology involving case study analyses and diverse data collection techniques. The case study properties are the structural systems, natural lighting, and the surrounding open spaces. As a result, a hotel with a multipurpose hall, and a museum dedicated to the history of the Silo have been proposed, aiming at conserving the valuable heritage in this industrial area as well as providing an alternative perspective for the adaptive reuse of industrial structures in Erbil city. Finally, the implications of the research for the economic and social dimensions of urban development lie in understanding and promoting sustainable preservation strategies. This work is considered the first step for future research in Iraq, specifically in Kurdistan Region. The research concludes that the Silo of Erbil is one of the successful examples of the process of reusing buildings. It also concludes that less intervention in reusing a building can protect the building identity.

Viral Hepatitis B and C Prevalence and Related Risk Factors Among Prisons in Duhok City, Kurdistan Region, Iraq.

Background Infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) are major public health problems worldwide. Public health services are still confronted with the problem of HBV and HCV infections, which calls for targeted preventative measures, especially for critical groups such as prisoners. Therefore, the study aims to measure the prevalence of HBV and HCV infections and to investigate their risk factors among prisoners in Duhok City, Kurdistan, Iraq. Methods A cross-sectional study was performed at the two main prisons inside Duhok city. There were a total of 1,013 inmates: at the Zerka jail, there were 945 male inmates, and at the Etiti jail, there were 50 adult females and 18 adolescent male inmates. Data collection was performed by a direct interview using a structured questionnaire on sociodemographic characteristics and risk factors. Serum samples were tested for HBV surface antigen (HBsAg) and HCV antibody (HCV-Ab) by enzyme-linked immunosorbent assay. Results The mean age of the participants was 35.9 years. The prevalence of HBV and HCV infections was 1.28% and 0.09%, respectively. HBV infection was significantly associated with occupation and marital status. The main risk factors were previous history of surgery and tooth extraction. Conclusions In conclusion, the prevalence of HBV was low while that of HCV was very low. It is usually recommended to take steps to screen for and treat HBV and HCV in patients.

Rock Slope Stability Assessment for Selected Sites at Imam Mohammed Road \ Sulaimaniyah Governorate \ Northern Iraq

A detailed engineering geological study was performed for rock slope stability for several selected sites at Imam Mohammed Road that connects Sulaimaniyah city and Darbandikhan town, the study included four sites in which a comprehensive survey was made for the rock slopes, the rocks forming them, and discontinuities affecting in them. The assessment of rock slope stability of the sites was executed through the stereographic projection, to determine the status of the slopes and discontinuities, field measurements revealed many occurred and probable failure types represented by the rock fall and sliding. The rock slopes were also classified based on three factors; divergence angle (parallel, oblique lateral, and orthogonal), Laterality (right and left emergent), and concordance (concordant and discordant). The rocks forming the slopes are described geometrically based on their color, grain size, texture, discontinuities, weathering, rock strength, lithology, and permeability. On the other hand, the risk of each site was also assessed depending on the Landslide Possibility Index (LPI), which showed that the first site lies within the (moderate hazard) category whereas the others lie within the (High hazard) category. Finally, some treatment strategies were proposed in order to stabilize the slopes and decrease the danger of their collapse on the road.

Lithofacies and Microfacies Study of ATE Maastrichtian Reefal Limestones and Comparison with the Aqra Formation, Northeast and Northern Kurdistan Region-Iraq

The Maastrichtian reefal limestone, which developed variably across the northern and northeastern Kurdistan Region of Iraq, includes the Aqra Formation, which formed extensive platforms in the Aqra-Barzan area throughout the Maastrichtian period. Additionally, bars and lenses of reefal limestone in the upper part of the Tanjero Formation created longitudinal submarine ridges in the Arabian-Eurasian Foreland basin. This study selected three sections: the Aqra Formation in the type section and study the reefal limestone lenses in the Upper part of the Tanjero Formation at the Kunamasi and limestone bars in the Balakaity. Focusing on lithofacies and microfacies to determine if these reefal limestones are part of the Aqra Formation. The type section of the Aqra Formation, located in the Aqra area, features significant reefal limestone approximately 700 meters thick, including rudists with bitumen and some dolomite content. This formation is widely deposited in the Aqra and Barzan areas, overlying the Bekhme platform stratigraphically, and extends geographically from Bujel to Chia Gara anticlines. Four submicrofacies identified in this reefal limestone are Miliolids packstone, Rudists floatstone, Peloidal grainstone, and Bioclastic foraminifera grainstone. In the Kunamasi area, the reefal limestone appears as thick deposits associated with marl and sandy claystone beds, approximately 30 meters thick, and situated above the flysch Tanjero Formation. Key submicrofacies here include Omphalocyclus packstone, Rudists floatstone, and Echinoids grainstone. At the Balakaity section, the reefal limestone consists of a single, thick body exceeding 50 meters in thickness, directly overlying the Tanjero Formation and restricted to the Dar-Alsalam area. The submicrofacies in this section include Foraminifera packstone, Omphalocyclus packstone, and Rudists floatstone. Overall, the microfacies interpretation is the Aqra Formation is deposited as a large platform in inner and middle ramp settings. Conversely, the reefal limestone in the Balakaity and Kunamasi areas appears to be part of submerging islands within the flysch marine environment of the Tanjero Formation during the active Arabia-Eurasian Subduction. Based on depositional context and microfacies analysis can be concluded the reefal limestone in these areas is more likely associated with the Tanjero Formation rather than the Aqra Formation.

Assessment of Slope Stability at Erbil Citadel, Kurdistan Region of Iraq Using Bejerman’s Method

The Erbil Citadel is located in the center of Erbil City; the capital of the Kurdistan Region of Iraq. The shape of the citadel is a large, oval hill. The Citadel was inhabited more than 6,000 years ago and is thought to be one of the longest-continuously inhabited sites in the world. Therefore, the Citadel was announced in 2014 as a World Heritage by UNESCO. The height of the Citadel is not uniform; it ranges between (28–30) m, the top elevation is 429 m (a.s.l.), whereas the bottom elevation ranges between (407– 416) m (a.s.l). The Citadel has an oval shape with diameters between (350 – 420) m, the E–W being the longest. The slopes of the Citadel (Tell) display severe erosion and slope stability problems, the main types are creep, which can endanger the existing historical buildings, especially on the edges of the Citadel. Different data about the Citadel have been reviewed but couldn’t find special studies concerning the slope stability of the Citadel. Therefore, we have applied Bejerman’s method, which is a quick field method to assess the slope stability of the slopes of the Citadel to find the Landslide Possibility Index (LPI). Eleven stations were selected around the Citadel to apply Bejerman’s method, the stations were selected in the site; wherever clear indications were found for slope instability. The results of the assessment showed that the LPI ranges between 18–22, which means grade IV, and Failure possibility of Medium (2 stations), and High (9 stations). Recommendations are given to keep the slopes of the citadel as safe as possible.

A Study on the Allelopathic Effects of Wild Barley (Hordeum spontaneum) Residue Incorporated with Soil on Growth of Some Plant species

This study examines the allelopathic effects of wild barley (Hordeum spontaneum) on the growth and yield of bread wheat (Triticum aestivum), barley (Hordeum vulgare), and wild barley (Hordeum spontaneum). The experiment was conducted in a greenhouse at Shamamar-Hawler/ Kurdistan Region of Iraq using a complete randomized factorial design (CRD) within 3 replications. The roots, shoots, and seeds of wild barley were dried, powdered, and added to the soil at different concentrations (0%, 10%, 20%, 30%, and 40%) in 500 g pots. Each pot was planted with 5 seeds, which were later reduced to 3 seedlings. Growth parameters such as shoot and root lengths, dry weights, number of tillers, weight of spikes, seeds number per plant, and biological yield was measured. The results indicated significant effects of wild barley residues on the studied crops. Wheat showed the highest roots, shoots and total lengths were (29.56 cm, 17.05 cm and 46.58 cm, respectively) and the highest shoots and roots dry weights were (0.24 g and 0.30 g). Barley showed the highest number of stems (1.96) but the lowest shoots and dry weights of roots were (0.11 g and 0.23 g). Wild barley had the highest biological weight and harvest index (HI). Among the plant parts, seed extracts significantly enhanced growth parameters, while roots and shoots extract had the greatest inhibitory effects as wild barley residue concentrations increased. Nevertheless, the HI showed a decline as the concentrations increased, suggesting a detrimental effect on growth efficiency. The study shows the potential of wild barley as a bio-herbicide, emphasizing its allelopathic effects. This suggests that agricultural practices should be carefully considered to maximize the efficiency of crops. Incorporating these results into precision agriculture can greatly improve crop management and increase yield.

Identification of Subsurface Geological Structures from Gravity Data by Modelling Techniques in Kalak-Bardarash Area, West of Erbil City Iraqi Kurdistan Region

A quantitative interpretation of gravity anomalies in the Kalak-Bardarash area, west of Erbil City in the Kurdistan Region of Iraq, was performed using two-dimensional analysis techniques. These techniques modeled geological structures identified from a previously created Bouguer anomaly map of the area. Five profiles were selected for the analysis, resulting in eight models constructed for both deep and shallow-seated rock units. The deep-seated rocks are represented by the basement rocks, with models constructed in the NNE-SSW, WNW-ESE, and NW-SE directions using the regional anomaly component. The depth of the basement rocks ranges from five to nine kilometers and is affected by numerous faults in the form of graben and step structures. The basement rock surface slopes towards the NE and ESE at a gradient of 110 m/km. The shallow-seated rocks are represented by the sedimentary cover, which includes Neogene, Paleogene, and Cretaceous-aged groups of formations. The residual component of the anomalies of the five profiles were interpreted. Three profiles, oriented NNE-SSW and nearly perpendicular to the main anticlinal structure, revealed that the Bardarash anticline is influenced by two faults striking both limbs and extending in the NNW-SSE direction, with an estimated throw of 200 meters on each side. The southern fault is believed to extend down to the basement rocks. The other two profiles, oriented NW-SE and nearly perpendicular to the Zab River, indicated the presence of two additional faults with a throw of approximately 600 meters in the deeper parts striking the basement rocks, dipping towards the southeast. The throw of these faults gradually decreases upward in the sedimentary cover, reaching about 200 meters. These faults directly influence the course of the Zab River, directing it in a NE-SW direction at this district.

Wastewater Management as a Part of Solution for Water Resources Problem in Erbil City

In Erbil City, municipal wastewater (MWW) is disposed directly without any treatment processes in the natural environment water body and in some places used for irrigation purposes. Untreated MWW causes problems for the environment, and people's health. Water quantity and quality variation produce complications for water sources in Erbil City, Kurdistan Region-Iraq. There is a lack of performing MWW management fundamentals in the area as well. This research aimed to study the MWW management in Erbil City, presenting water resource difficulties and bringing about suitable solutions for the water resource problems, and also to highlight the risk for the poor Management. MWW Data on Erbil municipal (EMWW) water quality parameters were collected and analyzed for the study period (four months), beginning in October 2022 and ending in March 2023. Twelve EMWW quality parameters were captured and tested in the Laboratory, arranged, and compared with MWW disposal criteria and local standards. The following MWW parameters include pH, electrical conductivity (EC), total dissolved salts (TDS), chloride (CL), total solids (TS), total alkalinity, total acidity, chemical oxygen demand (COD), and colour. The results showed that Erbil's MWW characteristics in terms of temperatures ranged between 11-23 °C and in turn, affected biological species activities. Maximum PH value was 7.7. Total alkalinity found in the range from 140 to 178 mg/l. Chloride concentration results showed for October was 62 mg/l and the maximum value was 80 mg/l in November due to the increment in temperature and evaporation. The range of the COD values of sewage water for five months was 246 -773 mg. Erbil's MWW's moderate to medium strength may be treated and utilized for landscaping, fountains, and irrigation, minimizing the need for fresh water from resources like wells and surface water in the Greater Zab River.
