Abstract (2. Language):
In the studies carried out until today, it was
determined that wastewater sourced from Konya city
reached to Salt Lake via D.S.I. irrigation channels
and therefore, heavy metal concentration present in
the wastewater led to heavy metal pollution in Salt
Lake.
In this present study; analysis of heavy metal
parameters through Konya Main Discharge Channel
were carried out and the results were evaluated
seasonally. Within the context of this study, totally
20 heavy metal (Ag, Al, As, Ba, Cr, Cu, Fe, K, Li,
Mg, Mn, Na, Ni, Pb, Se, Sn, Zn, B, Hg, P)
parameters were considered in 28 samples collected
in four seasons being winter, summer, spring and
autumn from 7 measurement stations in 2014.
When the results of analysis were investigated, it
was determined that the parameters of especially
arsenic, barium, chromium, copper, nickel, lead, tin
and boron in autumn were found differently higher
than other seasons. It was also indicated that heavy
metal concentrations in spring, summer and winter
were generally close to each other. The distance
between 1st pump and supply station was 30 km and
so water comes by becoming rare since the distance
between stations was the longest distance.
Moreover, since the farmers use the wastewater for
the aim of irrigation in this region, the water also
becomes rare. Becoming rare continues in the
stations of 2nd pump, 3rd pump and 4th pump. Also
since this region always gets rain in every season, it
was considered that becoming rare continues by
increasing.
It was observed that heavy metal results were lower
than maximum heavy metal limits permitted in
wastewater discharged to receiving environment
indicated in Water Pollution Control Regulations.
Moreover, when these analysis results were
compared to limit values of toxic materials in
Turkish Standard Institution (TSI), World Health
Organization (WHO) and USA Environmental
Protection Agency (US EPA), it was determined that
the results were lower than these values.
As a result of analysis and investigations; formation
of heavy metal pollution in Salt Lake due to
wastewater sourced from Konya seemed not
possible. In using the channel water for the aim of
agriculture, there seemed no problem in terms of
heavy metal pollution. After taking constructed
Konya Wastewater Treatment Plant into operation,
it was determined that the quality of wastewater
given to State Hydraulic Works (SHW) channels was
improved seriously.
The reason for analysis results to be found lower
than standards according to ‘Water Pollution
Control Regulations’ was that the domestic
wastewater was given to the channel after treated in
Konya Wastewater Treatment Plant and also
industrial wastewater of Konya Organized Industry
was given to the channel after treatment. Since the
wastewater of large scale industrial factories the
numbers of which are increasing day by day in
Konya region is also pre-treated by Konya
Wastewater Treatment Plant and given to water
supply network, it is considered that this has nonnegligible
benefits.
In order to investigate social, economic,
agricultural, ecological and cultural dimensions of
this subject profoundly, it is necessary to perform a
detailed SWOT analysis (strengths, weaknesses,
opportunities and threats) of the current situation.

Abstract (Original Language):
Yapılan araştırmalarda, Konya İlinden kaynaklanan atıksuların, D.S.İ. sulama kanalı vasıtasıyla Tuz
Gölü’ne kadar ulaştığı, sudaki ağır metal konsantrasyonlarının Tuz Gölünde ağır metal kirliliğine neden
olduğu belirtilmektedir. Yapılan bu çalışmada; Konya Ana Tahliye Kanalı boyunca ağır metal
parametrelerinin analizi yapılarak sonuçlar mevsimsel olarak değerlendirilmiştir. Çalışma kapsamında
2014 yılında 7 adet ölçüm istasyonundan; ilkbahar, yaz, sonbahar, kış olmak üzere 4 mevsim alınan toplam
28 adet numunede 20 adet ağır metal (Ag, Al, As, Ba, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Se, Sn, Zn, B,
Hg, P) parametresine bakılmıştır. Analiz sonuçları incelendiğinde; özellikle arsenik, baryum, krom, bakır,
nikel, kurşun, kalay ve bor parametrelerinin sonbahar döneminde, diğer mevsimlerden farklı olarak daha
yüksek değerde olduğu tespit edilmiştir. İlkbahar, yaz ve kış dönemlerindeki ağır metal konsantrasyonlarının
ise genel olarak birbirine yakın olduğu belirlenmiştir. 1.Pompa istasyonu ile terfi istasyonu arasındaki
mesafenin uzun olması ve bu bölgede çiftçilerin atıksuyu, sulama suyu amaçlı kullanmaları nedeniyle su
seyrelerek gelmektedir. Bu bölge her mevsim sürekli yağış alan bir bölge olduğu içinde seyrelmenin artarak
devam ettiği düşünülmektedir. Ağır metal analiz sonuçlarının ‘Su Kirliliği Kontrolü Yönetmeliğinde’ (SKKY)
belirtilen alıcı ortama deşarj edilen atıksularda izin verilebilir maksimum ağır metal limitlerinin altında
olduğu belirlenmiştir. Ayrıca analiz sonuçları; Türk Standartları Enstitüsü (TSE), Dünya Sağlık Örgütü
(WHO) ve ABD Çevre Koruma Ajansına (US EPA) göre toksik maddelerin sınır değerleri ile
kıyaslandığında da sonuçların bu değerlerin altında olduğu tespit edilmiştir.
