چکیده مقاله :
افزايش روزافزون اقبال به استفاده از منابع آب زيرزميني به عنوان يكي از منابع مهم تامين آب شرب مبين اهميت ارزيابيهاي كيفي اين منابع ميباشد. خصوصيات ميكروبي و فيزيكوشيميايي آب، مقبوليت و قابل شرب بودن آن را نشان ميدهد. هدف از اين پژوهش بررسي پارامترهاي ميكروبي، فيزيكوشيميايي، خصوصيات شوري و خورندگي آب شرب روستاي فرارت و همچنين بررسي تغييرات زماني اين پارامترها ميباشد.
در این پژوهش مطابق با استاندارد ملی ایران به شماره 2348 نمونه های آب نمونهبرداری شده و سپس در آزمایشگاه مطابق با استاندارد های ملی ایران به شماره 1011 و 1053 مورد سنجش میکروبی و فیزیکوشیمیایی قرار گرفتند. همچنين كيفيت آب توسط نمودارهاي گرافيكي شولر، پايپر و دورو تعيين شده است.
در بررسي خصوصيات ميكروبي چند مورد آلودگي چاه و شبكه مشاهده گرديد كه از جمله دلايل آلوده شدن چاه عدم رعايت حريم منبع و گرماي هوا و شيوع آلودگيها و دليل آلودگي شبكه آب نبود كلر در شبكه (اتمام كلر، شكستگي در لوله كلرزن) بوده است. بررسی کیفیت فيزيكوشیمیایی چاه و شبکه توزیع طی این دوره 8 ماهه نشان داد اکثر پارامترها دارای روندی صعودی در فصل گرم سال هستند ولی تغییرات و افزایش املاح در محدوده استاندارد ملی بوده و از لحاظ کیفیتی تاثیر چندانی بر آب شرب نداشت. مطالعات گرافيكي تيپ آب را در تمامي موارد بيكربنات كلسيمي معرفي نمودند. به طور كلي از نظر شرب آب كيفيت آب در محدوده استاندارد و قابل استفاده ميباشد.
Introduction: The increasing reliance on groundwater resources as a significant source of drinking water underscores the importance of quality assessments of these resources. The microbial and physicochemical characteristics of water indicate its acceptability and potability. The objective of this study is to investigate the microbial and physicochemical parameters, salinity, and corrosivity of drinking water in Fararat village.
Methods: In this research, water samples were collected according to the Iranian national standard No. 2348 and subsequently analyzed in the laboratory following the national standards No. 1011 and 1053 for microbial and physicochemical testing, respectively. Additionally, the quality of water was determined using Schoeller, Piper, and Durov graphical diagrams.
The assessment of microbial characteristics revealed several instances of contamination in both wells and the distribution network. Notable reasons for well contamination included non-compliance with source protection zones, high ambient temperatures, and widespread pollution. For the distribution network, contamination was attributed to a lack of chlorine (due to depletion or breakage in chlorination pipes).
Findings: The evaluation of physicochemical quality over an eight-month period indicated that most parameters exhibited an upward trend during the warm season; however, changes in salinity remained within national standards and did not significantly impact drinking water quality. Graphical studies identified the water type as calcium bicarbonate in all cases. Overall, from a drinking perspective, the water quality falls within acceptable standards and is deemed suitable for use.
