Abstract/ Executive Summary:

A study was conducted to evaluate the water quality parameters of pond water at Mymensingh Urban region. The water samples were collected from 30 ponds located at Mymensingh Urban Region during August to October 2010. The chemical analyses of water samples included pH, EC, Na, K, Ca, S, Mn and As were done by standard methods. The chemical properties in pond water were found pH 6.68 to 7.14, EC 227 to 700 μScm-1, Na 15.57 to 36.00 ppm, K 3.83 to 16.16 ppm, Ca 2.01 to 7.29 ppm, S 1.61 to 4.67 ppm, Mn 0.33 to 0.684 ppm and As 0.0011 to 0.0059 ppm. The pH values of water samples revealed that water samples were acidic to slightly alkaline in nature. The EC value revealed that water samples were medium salinity except one sample and also good for irrigation. According to drinking water standard Mn toxicity was detected in pond water. Considering Na, Ca and S ions pond water was safe for irrigation and aquaculture. In case of K ion, all the samples were suitable for irrigation but unsuitable for aquaculture.

Keywords: Mymensingh municipality, Water pollution, Water quality

Location: different ponds of Mymensingh.

Start Date: 00-08-2010

End Date: 00-10-2010

Program Area: Crop-Soil-Water Management

Commodity: Water quality

Objectives:

1.To determine the chemical constituents of pond water and their degree of toxicity.

2.To identify the suitability of fresh water for irrigation, drinking and aquaculture on the basis of international standard.

Methodology:

Selection of study area: The district of Mymensingh is situated between 24°02„03" and 25°25„56" north latitude and 89°39„00" and 91°15„35" east longitude. Mymensingh city is clearly marked by the old Brahmaputra River flowing along its north. Management of water environment spatially pond water in this densely populated Mymensingh urban region is difficult and costly but crying need for better livelihood and in the point of health.Collection of water samples: Thirty samples were collected from different ponds of Mymensingh urban region during August to October 2010. The water samples were kept and preserved in 100 ml plastic bottles after collection.Analytical methods of water samples: The analyses were accomplished at the “Humbold Soil Testing Laboratory” of Bangladesh Agricultural University, Mymensingh and Department of Public Health Engineering (DPHE), Mymensingh. The following analyses have been done from the collected water samples.Statistical analysis: After chemical analysis data were statistically analyzed with the help of computer following the standard procedure (analysis of variance) as described by Gomez and Gomez (1984), Correlation studies were also done by computer with standard procedure.

Achievement/Findings:

From the study it may be concluded that the ponds of Mymensingh urban region contained acceptable amount of Na, K, S and As where Mn exceeded the recommended limit for drinking water, irrigation water and for aquaculture. In that sense it is hazardous for health, crops and aquaculture. All the water of ponds of Mymensingh urban region can safely be used for specific purpose after proper treatment. Routine research work with wide public awareness, government participation and regulations can save the water of Mymensingh urban region and thus a safe and sound water environment can be made for future generations.
