| dc.description | Water is life. Water is the most essential natural resources on the earth. Quality of water is
not only essential for irrigation but equally important for drinking, domestic, livestock, fish
production and industrial purposes. Clean water is also necessary for human health and
livelihood as well as being interwoven into many cultures. Now a days, water quality is a
critical issue for many Asian countries, with a rise in water demand paralleled with a decrease
in the amount of usable water, due to degraded water quality. Water is the fluid of life not
only for human beings but also for any living organism. The main sources of water in
Bangladesh are surface waters in rivers, reservoirs, lakes, canals and ponds, and the ground
water in deep and shallow aquifer (Ahmed and Rahman, 2003). Soil properties, crop yield
and quality will be deteriorated if low quality water is used for irrigation (Prunty et al. 1991,
Sarker et al. 2000 and Sarker et al. 2003). | en_US |
| dc.description.abstract | Surface water samples (60 ponds and 10 samples from two rivers in different sampling
sites) collected from the Thakugaon Sadar Upazilla, Thakurgaon, Bangladesh in dry season
of the year 2012 and analyzed for its quality and suitability for agricultural and aquatic
purposes. Analyses included pH, EC, temperature, dissolved oxygen (DO), chemical oxygen
demand (COD), alkalinity, cations (Ca®", Mg", Na’, K‘, Zn”*, Cu", Mn” and Fe”), anions
(CO;*, HCO;, NH3, NO.”, NO;,, $O,7, total nitrogen, total phosphorus and CI) and TDS
(Total Dissolved Solids). Several variables such as SAR (Sodium Adsorption Ratio), SSP
(Soluble Sodium Percentage) RSC (Residual Sodium Carbonate) and hardness were also
computed. Overall we found that the pond water were acidic in nature (pH varied from
5.3 to 7.1) and could be suitable for agricultural and aquatic uses. Pond water samples
contained Ca”, Mg” and Na’ as the dominant cations and HCO; and CI were the
dominant anions. According to TDS and SAR values, all samples were classed as
“freshwater and ‘excellent’ categories. The soluble sodium percentage (SSP) of all waters
was under ‘excellent’ and ‘good’ classes. All samples were within ‘soft’ class regarding
hardness with ‘suitable’ RSC. Based on Zn", Mn”, Fe”, $O,7, NO; and CI all pond water
samples were within the ‘safe’ limit for irrigation used in dry period. The DO concentration
was suitable for fish production but more DO level should be present for all aquatic life
especially for fish production. COD level of all pond waters were within the permissible
limits for fish production. However, water quality parameters of pH, temperature and DO
are dominant factors to affect the growth of fish although BOD and COD parameters are
not meeting the criteria. The studies were undertaken from the month of May to June, 2012
during which the physic-chemical parameters were analyzed and compared with the
aquaculture water quality standard of Kumar (2004). | en_US |
