Abstract

Istanbul is a city of 16 million, accounting for almost a fifth of the population of Turkey, therefore providing quality drinking and use water is vital. To evaluate the results of drinking and city water analysis in Istanbul in 2017. This is a descriptive study using retrospective data. Inspection monitoring and control monitoring samples collected 748 monitoring points from 36 water plants around Istanbul in addition to Residual Chlorine measurement samples from 548 points. These samples were analyzed in Istanbul Public Health Reference Laboratories (HSL). Data analysis was carried in SPSS 21.0, statistical analysis were described as percentage, mean, standard deviation. Statistical significance was accepted as p<0.05 with a 95% confidence interval. Mean pH level in İstanbul’s drinking and usage water was 6.95±0.14 (min:6,62-max:7,28); mean Coliform Bacteria levels were 17.09±99.47 (min:0.00-622.00) /100 ml; mean conductivity was 376.22±78.52 (min: 282.06 max:613.73) μS/cm; mean Escherichia coli per. 3.13±18.98 (min:0,00-max:118.60); mean iron levels were 34.39±18.81 (min:6,79-max:103.70) μg/L. 90.2% of inspection monitoring samples, 96.9% of control monitoring samples, and 99.5% of residual chlorine analysis were at acceptable levels. Water quality analysis in Turkey is done by various organizations and multiple branches of government under national and international regulations. Monitoring and analysis procedures are independent of each other and currently, no integrated monitoring strategies are in place, although several actions on this front have started. An integrated system of data collection and analysis between all stakeholders is needed to increase time and workload efficiency in water quality evaluation.

İSTANBUL İLİ 2017 YILI İÇME VE KULLANMA SULARININ DEĞERLENDİRİLMESİ

Abstract

İstanbul, Türkiye nüfusunun yaklaşık beşte birini oluşturan 16 milyonluk bir şehirdir, bu nedenle kaliteli içme ve kullanma suyu sağlamak hayati önem taşımaktadır. Bu çalışmada İstanbul ilindeki 2017 yılı içme kullanma sularının analiz sonuçlarının değerlendirilmesi amaçlanmıştır. Araştırma retrospektif verilerin kullanıldığı tanımlayıcı bir çalışmadır. İstanbul ilinde 36 noktada bulunan şebekelerden belirlenen 748 izleme noktasından Kontrol İzlem ve Denetim İzlem numunesi, 548 izleme noktasından Bakiye Klor Ölçümü numunesi alınarak, bir tanesi Anadolu yakasında iki tanesi Avrupa yakasında olmak üzere İstanbul Halk Sağlığı 1-2-3 No’lu Referans Laboratuvarlarında (HSL) analizleri yapılmaktadır. Veriler SPSS 21.0 paket programı ile değerlendirilmiş, istatistiksel analizlerde yüzde, aritmetik ortalama, standart sapma kullanılarak yorumlanmıştır. İstatistiklerde %95 güven aralığı ve anlamlılık düzeyi p<0,05 olarak kabul edilmiştir. Araştırmada İstanbul ilindeki içme kullanma sularındaki ph değeri ortalaması 6,95±0,15 (min: 6,62-maks: 7,28); Koliform bakteri değeri ortalaması 17,09±99,47 (min:0,00-622,00) /100 ml; iletkenlik değeri ortalaması 376,22±78,52 (min: 282,06- maks:613,73) μS/cm; Escherichia coli miktarı ortalaması 3,13±18,98 (min:0,00-maks:118,60); demir miktarı ortalaması 34,38±18,81 (min: 6,79-maks: 103,70) μg/L olarak saptanmıştır. Araştırmada yapılan denetim izlem sonuçlarının %90,2’si, kontrol izlemlerinin %96,9’u ve bakiye klor ölçümlerinin %99,5’u uygun saptanmıştır. Ülkemizde su kalitesi izleme çalışmaları, çeşitli kurum ve kuruluşlar tarafından ulusal ve uluslararası sorumluluklar kapsamında yürütülmektedir. Çalışmalar birbirinden bağımsız olup, henüz entegre bir kirlilik izleme stratejisi uygulanmamaktadır. Bu konuda ortak paydaşlar ile çeşitli çalışmalar yapılmaktadır. Su kalitesi izleme çalışmalarını yürüten kurum ve kuruluşlar ile birbirine entegre ortak bir veri tabanı oluşturularak yapılan çalışmaların sonuçları paylaşıldığı takdirde zaman ve insan gücü kaybının da önüne geçilmiş olacaktır.
