Abstract/ Executive Summary:

The case study was conducted in 2014 to assess the physico-chemical properties of the water from the Gorai river in Kushtia, Bangladesh. To conduct this research, six samples from six points were collected from surface water of this river that covered only the Kushtia town. Samples were collected from Charulia, Barokhada, Jugia, Kamlapur, Thanapara and Ghoshpara at 1km interval. Another three samples were collected from Jagati sugar mill area and two domestic effluents those were discharged to the main river flow to evaluate the impact of these effluents on the river water quality. Different water quality parameters such as temperature, pH, Electrical Conductivity, Total Dissolved Solids, Dissolved Oxygen, Alkalinity, Hardness, Sodium, Potassium, Phosphate, Sulphate, Chloride, Iron, Lead, Cadmium and Chromium were examined. From this study it was observed that most of the parameters exceeded the permissible limits.

Program Area: Knowledge Management

Commodity: Contamination

Objectives:

To measure the various physico-chemical parameters of water of the Gorai river, Kushtia
To assess the status of river pollution related to water quality

Methodology:

Study area: The Gorai River, which passes through Kushtia town of Bangladesh and meets with the Madhumati River at Mohammadpur upazilla in Magura district. From origin place Talbaria to Kushtia town has been selected as the study area. A small part of the Gorai River was selected as sampling sites. Water sampling was started from the point, 89⁰06.773'E and 23⁰56.649'N, at an interval of 1 km for 6 km. The sampling sites were selected due to their extensive industrial and domestic operations with several point sources and non-point sources of pollution. The point sources include sugar mill’s waste water and domestic waste water from Kushtia pourashova area including market. In addition, disposal of solid wastes and untreated sewage also contribute contaminant loads as point sources.

Sampling site: Nine water samples were collected from this study area. Among these, six samples were collected from the surface river water (5 -10 cm) at selected 6 points and other three samples were collected from the domestic waste water drain and Sugar mill effluent drain. The samples were collected in winter season. Locations were identified with location name and with the help of GPS (Model: eTrex, Garmin, Taiwan).

Collection and preservation of samples: Sampling was carried out during November in 2014 from nine sampling locations. The samples were collected from the river surface level (5-10 cm) during day time. A minimum of three samples were collected from each point. The water samples were collected in sterilized bottles with caps (250 mL). One of the three samples was preserved with nitric acid for heavy metal analysis for each point. The bottles were kept air tight and labeled properly for identification. The samples were brought to the BCSIR laboratory for analysis. They were thoroughly cleaned by rinsing with 0.1 N HNO₃ and deionized water, followed by repeated washing with river water to avoid contamination in the bottle. Different water quality parameters were determined using the following methods: All the samples were analyzed under Soil, Agronomy and Environmental Section in BCSIR Lab. The instruments and methods used to complete the analysis.

Achievement/Findings:

This experiment was conducted in the area of the Gorai river where the effluent of sugar mill and domestic waste water discharged. For completing this study six samples were collected from surface water of river and three samples from effluent drain. Temperature of water samples recorded at different points and effluents was within allowable limit. All values of pH for water samples and effluent indicated that the water of this river was basic and were within permissible limit {6.5-8.5}. The Dissolved Oxygen (DO) concentrations were within the permissible limit (6) except the sampling point Ghoshpara. Where, DO concentration of effluent exceeded the allowable limit. In this experiment, it was observed that the concentrations of total hardness of effluent were higher than the river water samples but didn’t cross the permissible limit. EC, TDS and alkalinity were found within the permissible limit of this river water but for the effluent, the values of EC exceeded the allowable limit; TDS and alkalinity values were within the permissible limit.

Concentrations of sodium, potassium, sulphate and phosphate were found high in respect of irrigation water but normal in respect of domestic usage at various sampling points. In the case of effluent , Na + and SO₄^2- values were high in respect of irrigation water but normal in respect of domestic usage but K + and PO₄^3- concentrations exceeded the both limits. Overall Iron concentrations of both river water and effluent exceeded the permissible limit in respect of irrigation and domestic water. In the case of chloride, both river water and effluent values didn’t cross the permissible limit. Then, the concentrations of lead, cadmium and chromium were below the detection level for river water. This could be reason for high pH. But for effluent, chromium values exceeded the limit of domestic water and in case of lead and cadmium were below the detection level. Therefore, the effluent coming from sugar mill and domestic effluent influenced the river water. It can be suggested that the water of the Gorai river would not be suitable for irrigation and domestic purposes without treatment.
