In this study, the drinking water quality of the Şenkale stream was researched. Firstly, water samples were taken from
Şenkale stream every month in 2016, 2017, and 2018. The water quality parameters such as temperature, pH, color,
electrical conductivity (EC), dissolved oxygen (DO), chemical oxygen demand (COD), total organic carbon (TOC),
biochemical oxygen demand (BOD5), suspended solid matter (SSM), nitrogen group, anion groups, phosphorus group,
oil and grease, cation groups, methylene blue active matter (MBAM), hydrocarbons, cyanide (CN-
), phenols, polycyclic
aromatic hydrocarbons (PAH), heavy metals and total pesticides were analyzed under the international standards. Hazen's
statistical method was used in the analysis of the data. The water quality of Şenkale stream was classified by the
Regulation on the Quality and Purification of Drinking Water Supply (RQPDWS) and Regulation Amending the
Regulation on Surface Water Quality (RARSWQ). According to RQPDWS; PAH and Fe are in the A2 quality class. NO3
, F-
, SO4
-2
, Cl-
, o-PO4-3
, CN-
, Pesticide, Al, Mn, Se, Cu, Zn, B, Co, Ni, As, Cd, Cr, Pb, Hg and Ba are in the A1 quality
class. According to RARSWQ; TKN and o-PO4
-3
are in between I.-II. quality class standards. NO-3
, F-
, Mn and Se are in
I. quality class. CN-
, PAH, Pesticide, Zn, B, Co, Ni, As, Cd, Pb, Hg and Ba are in the below the maximum environmental
quality system value. Al, Fe and Cu are in the above the maximum environmental quality system value.
