| dc.description | Groundwater quality is inevitable not only for successful crop production in
irrigated area but also for sustainable growth, development and management of
livestock, poultry, aquaculture and agri-based industries. In Bangladesh, most of
the farmers depend on groundwater for irrigated agriculture. During dry season,
surface waters like rivers, canals and beels become almost dry and farmers are
compelled to use groundwater. For successful crop cultivation, irrigation is
practiced to meet the requirement of moisture in soils but groundwater use for
irrigation contains some dissolved constituents. Some dissolved elements and
compounds may affect the irrigated soil environment by accumulating the
harmful and toxic elements in the soil, which ultimately reduces productivity of
agricultural land (FSES, 1995). The poor quality irrigation water affects the
crop growth directly and reduces the crop yield drastically. So, groundwater
quality is important factor to minimize environmental pollution in soil-waterplant system. | en_US |
| dc.description.abstract | An experiment was conducted to evaluate the ionic status and relationship
of As with other ions of groundwater in 3 Upazila (Gopalganj sadar,
Tungipara and Katalipara) of Gopalganj district. A total of 65 water
samples from different village of three upazilas were collected during
March to April 2009. The samples were chemically analyzed and
classified on the basis of their comparative suitability for irrigation and
see the relationship between As and other ions. The chemical analysis
included pH, EC, Ca, Mg, K, Na, Fe, Mn, Cu, P, B, As and S. On the
basis of pH water samples were neutral to slightly alkaline and suitable
for irrigation. On the basis of Mn and Mg contents. The samples were not
problematic. Results showed that not a single sample was free from
arsenic contamination though their concentration varied with the
locations. The higher As concentration was recorded as 0.20 mg L” at
Boragitola village in sadar upazila and the lowest 0.01 mg L" at
Krisnopur village in sadar with the mean value of As concentration being
0.07 mg L’'. The highest As concentration was about four times higher
and the mean As concentration was 0.02 mg L" higher than the maximum
permissible limit for drinking water (0.05 mg L’'), respectively. The As
concentration of groundwater of samples were higher than the maximum
permissible limit in all upazilas. Significant relationship was found
between As and other elements like P, S, B, Cu, and Mg. The highest
correlation co-efficient (r) value was obtained with As vs Cu (r = -0.484).
A conclusion can be made that groundwater may be a good factor for As
contamination in soils as well as crops. | en_US |
