Determination of Surface Water Quality for Irrigation in Dinajpur
2021
Md. Motaharul Islam | Mst. Taslema Nasrin | Md. Mofizul Islam
A research was carried out to assess the suitability of surface water for irrigation purposes. For this reason, 56 samples of surface water were collected from each union of Dinajpur sadar upazilla, Dinajpur. The analysis was included pH, EC, TDS, Ca, Mg, S, P, Na, K, Cl- and HCO3- to evaluate the suitability of surface water for irrigation purposes. Almost all the water samples were within the recommended pH value for irrigation and a great impact on crop production. With respect to electrical conductivity (EC) samples were low to medium salinity. For total dissolved solids (TDS), all samples were considered as freshwater for irrigation. On the basis of Ca, Mg, S, P, Na, K, Cl- and HCO3- all samples could safely be used for irrigation and would not affect the soils.

In this study, through the analyses of water samples taken from 9 stations on the brook between July 2012 and June 2013, we aimed to determine the monthly and seasonal changes in water quality parameters of Brook Kuruçay, to determine the water quality properties, to reveal the pollution problems, to determine the suitability level in terms of aquatic life and to classify the quality of water in accordance with Surface Water Quality Management Regulation’s Inland Surface Water Classes criteria. The study area is located southeast of the Hafik District of Sivas city and the altitude is 2608 m. The water samples were collected from 9 stations established on the brook, and some physicochemical parameters and heavy metal concentrations were analyzed in water samples. The cleaning and maintenance of all of the equipment, land-type measurement tools, and glass sampling containers to be used in sampling were made 1 day before sampling. Sampling tubes were immersed into 15 cm below the water surface for taking water samples. Heavy metal concentrations were determined in the Sivas Provincial Control Laboratory in the same day with sampling (within 5 hours). The total alkalinity, total hardness, ammonium nitrogen, nitrite, nitrate, ammonium azote, phosphate, sulfite, sulfate, chloride, sodium, potassium, suspended solid matter (SSM), chemical oxygen demand (COD), biological oxygen demand (BOD), calcium, magnesium, ferrous, lead, copper, zinc, nickel, mercury and cadmium analyses of water samples were performed.As a result of the analyses, it was determined that, since Brook Kuruçay falls into the water resource class, which is the most sensitive to pollution, the water quality of the brook should be monitored regularly.

The main aims of this study were to observe the seasonal variations of physicochemical parameters and heavy metal content, to determine the water quality properties and the suitability level in terms of aquatic life, and also to classify the quality of water in accordance with the Surface Water Quality Management Regulation (SWQMR) criteria at Çiğdem Pond (Kastamonu/Turkey). In total, 21 physicochemical parameters and 7 heavy metals were investigated for water quality assessment of the studied pond between July 2015 and June 2016 in 3 stations. The water quality in Çiğdem Pond was found to be Class I according to SWQMR. The results of this study provide a data baseline for future studies on subsequent evaluations of possible future environmental contamination. Also, to protect the water quality and to ensure the health of aquatic life in this area, it is required to make regular observations.

2019
Oylum Gökkurt Baki
The study investigated the water quality characteristics of the spring waters, creeks and lakes in Yalova Province, Turkey. The 12-month study was carried out in 2005 and the same study was repeated in the same stations in 2008. Water samples were collected from 9 stations on a monthly basis. For the determination of the water quality, dissolved oxygen, pH, temperature, ammonium nitrogen, nitrite and nitrate nitrogen, potassium, total copper, chlorine, sulphate, iron, phosphate, zinc and sulfide analyses were performed. The water quality parameters of the spring waters, creeks and lakes were determined with respect to months and years. The stations that are known to receive wastewater and solid waste inputs were revealed to have high concentrations of water pollution-indicating parameters.
