Abstract—Water quality monitoring and assessment has
become a critical issue because it affects human and aquatic life.
In recent years Beki River of Assam, India have encountered
serious threats which includes sand mining, use of fertilizers on
the river banks, uncontrolled fishing that have altered the water
quality of the river specially in the fish landing sites. These have
caused significant reduction in abundance of the fresh water
fishes in the region. This study identifies the parameters that
are responsible for decreasing the water quality in the six fish
landing sites of the river. The study shows low pH of the river
water indicating its acidity nature. Decrease in Dissolved
oxygen (DO) during the monsoon in Dumnigh at, Sapakama
and Madulijar suggested poor quality of water indicating the
slow rate of photosynthesis by phytoplankton present in the
Beki River. The concentration of Iron in Gobardhana,
Sapakama and Dumnigh at during post monsoon was higher
than the maximum limit of 0.3 mg/l. Concentration of nitrate
was found to be higher than the limit of 45 mg/l in all the
landing sites except for Gobardhana due to application of
inorganic nitrogen fertilizers in the agricultural farm in the
river bank. Concentration of manganese, arsenic and lead was
found to be higher than the maximum limit in the fish landing
sites. The spatial variations of the major ions reflects the
influence of various anthropogenic and lithology’s activities in
the river system.
Index Terms—Beki river, water quality, fertilizers, anthropogenic, dissolved oxygen, arsenic, lead.
