What is
the general situation with water quality?
Surface water
quality. Surface water quality is controlled by the
State Enterprise for Meteorology at the Ministry of Ecology and
Emergencies. Control is done only at the Alamedin
(1 km north from the city) and Ala Archa
(4 km south from the city) rivers. The
surface water quality is evaluated in conformity with the national
system of maximum allowable concentration standards regulating
normal concentrations for surface water used for drinking, domestic,
cultural and fishery purposes. Of all the normal values the
strictest one is used.
Ground
water quality. The
water quality control in sources and water pumping points (taps,
water-pumps,
386 control points altogether) is done by the laboratories of
Bishkekvodokanal and the City Sanitary and Epidemiological Station
in conformity with potable water requirements. On the whole, the
ground water quality meets the standards. At times pollution of
water by chromium is recorded. The content of nitrates of organic
origin is high. For example, in the Orto Alysh water intake their
content has grown from 5 mg/l (1991) to 20 mg/l, and in some areas
it reaches 60 mg/l. The microbial contamination of water sources is
on the level of 0.5 –1.8% of analyses; the secondary microbial
contamination is 2.5 – 4.3%.
