چکیده مقاله :
زمینه و هدف: تامین آب آشامیدنی سالم برای مصرف انسان به میزان کافی و بهداشتی بسیار با اهمیت است. بنابراین آگاهی از کیفیت فیزیکوشیمیایی منابع آبی می تواند نقش عمده ای در بهره برداری و مصرف آنها جهت آشامیدن داشته باشد. اندازه گیری و پایش پارامترهای کیفی آب اولین قدم در تضمین آب سالم می باشد. هدف از این پژوهش بررسی کیفی آب چاههای شرب دشت زرقان در استان فارس بود.روش بررسی: بدین منظور از داده های هواشناسی، سطح تراز آب زیرزمینی و نتایج آزمایشات فیزیکوشیمیایی 12 متغیر شامل کل جامدات محلول، سختی کل، هدایت الکتریکی، pH، سولفات، بیکربنات، نیترات، سدیم، کلسیم، منیزیوم، کلراید و فلوراید از ده حلقه چاه شرب منطقه روستایی زرقان طی سالهای 95-1390 استفاده شد.یافته ها: داده های موجود توسط آزمونهای همبستگی پیرسون و تی تک نمونه ای توسط نرم افزار SPSS تجزیه و تحلیل شدند. نتایج مقایسه پارامترهای مختلف آب چاه های منطقه زرقان با استاندارد ملی در دوره 5 ساله نشان داد که با کاهش تراز آب زیرزمینی ناشی از خشکسالی میزان منیزیوم، کلراید، سدیم، سختی کل و هدایت الکتریکی افزایش یافته و بیشتر از حد مجاز استاندارد برای آشامیدن شده اند.بحث و نتیجه گیری: آب چاههای شماره 1، 2، 4 و 7 از نظر کیفیت به مراتب نسبت به چاههای 5، 6، 9 و 10 از سطح بهتری جهت آشامیدن برخوردارند که بدلیل کاهش بارش و خشکسالی، برداشت بی رویه از منابع آب زیرزمینی و تفاوت در جنس و نوع خاک هر قسمت از منطقه است.
چکیده انگلیسی:
Background and Objective: Providing safe drinking water is so essential for human consumption adequately and healthy. Therefore, knowledge of the physicochemical quality of water resources can play a major role in their utilization and consumption for drinking. Measurement and monitoring of water quality parameters is the first step for ensuring safe water. The aim of this study was to investigate the quality of drinking water wells of Zarghan plain in Fars province.Methods: For this purpose, the data of meteorology, groundwater level and physicochemical experiments of 12 parameters including Total Dissolved Solids, Total Hardness, Electrical Conductivity, pH, Sulfate, Bicarbonate, Nitrate, Sodium, Calcium, Magnesium, Chloride and Fluoride of ten drinking water wells in Zarghan rural district during 2011-2016 were used.Findings: Data were analyzed by Pearson correlation matrix and one sample t-test using SPSS software. The results of comparing different parameters of water wells in Zarghan area with the national standard during 5-year-period showed that with decreasing groundwater level due to drought, the amount of Magnesium, Chloride, Sodium, Total Hardness and Electrical Conductivity increased and exceeded the maximum standard limit for drinking.Discussion and Conclusion: Water wells no. 1, 2, 4 and 7 have a better level of drinking water quality than water wells no. 5, 6, 9 and 10 due to decreasing rain and drought, uncontrolled harvesting of groundwater resources, and differences in the matter nature and type of soil of each part of the area.
