Abstract/ Executive Summary:

Abstract: Some important characteristics of surface water quality of Chittagong University campus, Bangladesh were evaluated for use in domestic, industrial, agriculture, recreation and aquaculture purposes. Fifteen water samples were collected and analyzed in the laboratory of the Department of Soil Science of the University of Chittagong. The study revealed that most physical parameters and inorganic elements are not a serious problem for the water bodies of Chittagong University campus. On the basis of sample analysis it can be said that the surface water of Chittagong University campus is suitable for common uses.

Objectives:

This research was aimed at making an assessment of surface water quality of the Chittagong University campus for domestic, irrigation, recreation and aquaculture purposes.

Methodology:

Fifteen (15) water samples were collected from different locations of the university campus. Sampling sites for water were selected as per a sampling technique [14] which represents the entire water bodies. The high-density PVC bottles used for water sampling were thoroughly cleaned by rinsing with 8M HNO₃ followed by repeated washing with water sampled so as to avoid contamination [14]. The sampling bottles were kept air tight and labeled properly for identification. Aeration during sampling was avoided as far as possible. Variable determinants such as temperature, electrical conductivity (EC), pH and dissolved oxygen (DO) of water samples were measured in the spot using thermometer, portable EC meter, pH meter and DO meter respectively [14, 15]. Samples collected from the study area were carefully transported to the laboratory, preserved in a refrigerator and were immediately analyzed for finding intended physical and chemical parameters of water. Analyses of different physical and chemical parameters were carried out in the laboratory of the Department of Soil Science, Chittagong University. The temperature of water samples were measured by the mercury thermometer (0°-50°C range) immediately after collection by dipping the thermometer in sample for about one minute [7]. Total Suspended Solids (TSS) and Total Dissolved Solids (TDS) were measured gravimetrically [6]. The pH of water samples were determined directly by a pH meter taking 50ml of water sample in a 100ml clean beaker [16]. The electrical conductivity (EC) of water samples were measured both in spot and in the laboratory directly by Electrical Conductivity meter (EC meter [16]. Micro Kjeldahl’s distillation method was followed to determine NH4-N contents [16]. Potassium (K), calcium (Ca) and magnesium (Mg) concentration of water samples were measured directly by atomic absorption spectrophotometer [15]. The chloride content of the water samples were determined by Mohr volume method [16].

Achievement/Findings:

The samples were analyzed for intended water quality parameters following internationally recognized and well established analytical techniques. From the present investigation it was observed that there were no extreme variations of surface water temperature and the ambient temperature. Dissolved Oxygen (DO) of the water of study area is suitable for most of the intended uses. Electrical conductivity (EC) of collected water samples is “excellent to good”. The TDS and EC values of the sampled water show moderate concentration of dissolved solids and non-saline water. It is evident that all the values of sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), chloride (Cl) and ammonium (NH4) falls under the permissible limit and there were no toxicity problem. Water samples showed no extreme variations in the concentrations of cations and anions. Thus, most of the inorganic elements are not a serious problem in terms of water contamination in Chittagong University campus.
