PFS “Surgil field complex costruction with valuable
components retrieval”
complexes are divided by regional very reliable clay confining beds upper jurassic,
upperaptsk and senon-palaeogene.
The chemical underground waters composition is characterized by the wide range of
mineralization from 17 to 200g/l, water density 1.082 – 1.106/sm 3 .
The sharp aggravation of ecological conditions in region is connected with pollution
of a drain of the Amu Darya and Syr-Darya rivers. Waters pollution in the rivers and
reservoirs occurs owing to dump of industrial and household sewage waters. There are
ingress the large amount of phosphorus, nitrogen and other substances compounds from
objects of agriculture, including toxic, containing in defomants, insecticides. Dump in the
rivers of highly mineralized collector-drainage waters causes the raised river flow
mineralization. Objects of “Ustyurtgaz” USE are located at considerable distances from
surface water objects.
Source of potable water supply of area is the Amu Darya River, which only in the
Karakalpakstan territory is polluted by 16 large collector-drainage and industrial drains.
Under the influence of agricultural drains and also sewage waters of the enterprises,
there is formed the degree of a chemical water composition of the Amu Darya river. The
Amu Darya River concerns to category of fish and economic significance, and also is used
for household water needs, including for needs of the objects of “Ystyurtgaz” USE.
The water supply problem is actual for considered region. The provision of the
population of the Republic of Karakalpakstan with tap potable water is 39% (urban 68%,
rural 13%). The main part of rural population uses water of open reservoirs.
There is used imported water for household needs in the nearest to Surgil field
settlements.
Existing industrial projects (East Berdakh, Urga, etc.) does not influence on the
surface and underground waters condition and in connection with remoteness of surface
waterways and absence of dump in them.
