Construction Slepyanskoy water system was completed in mid-1980. The scale is done by architects now hard to imagine. All work was performed under low water regime of the city in an environmentally neglected cleaning schedule areas. Instead of technical channels and underground conduits to enterprises was reclaimed over 150 hectares of land previously occupied by perennial industrial waste landfill. Over a decade of work the city has received almost continuous system of parks and gardens with a total area of 300 hectares, which can simultaneously rest more than 60 000 people. cleaning schedule
The north-eastern semicircle with a total length of 22.5 km was created on the basis of the creek Slepyanka. Begins Slepyanskaya water system has an average of the waters of the reservoir space invaders, from using a special water pump station closed conduits, passing under virtually the entire northern part of the city, served in the head reservoir.
Along the channel created walking area and currently laid bikeways. Periodically arranged stair slopes to the water, decorated with beautiful trees and boulders. From the streets of Benaiah water and green zone system is solved relatively narrow channels, cascades and small ponds elongated shapes. Due to planning restrictions and the low flow of water, part of which goes to the technical water supply of the city, it is the low-water site.
Unfortunately, the architects could not (or not yet) do Slepyanskuyu water system is completely continuous. Lane section from Kozlov to Moscow railroad line runs only conditionally and virtually neblagoustroen.
For modern man, weary urban rhythm cleaning schedule of life, noise, car exhaust fumes just need to communicate with nature. Her beauty, the splash of water, rustling leaves cleaning schedule helps to restore physical and spiritual strength.
In 2011, students GUO "High school 108 of Minsk" started work on the project "Assessment of the ecological status of the territory Partyzanski district of Minsk." Parameters were investigated ecological condition of the soil, the lower layers of the atmosphere in the area. According to the results of the maps of pollution sources and safe places for residents. Open ecological site "Environmental News +", where all the information is available on the research area of ecology.
There are many ways of determining the water quality. Modern methods of assessing the level of pollution of surface waters is based on two principles: determination of individual pollutants using sensitive instruments and assessment of the total toxicity of impurities using organisms indikatorov.Dlya assessment of the state of water in the channel we used in two ways.
In early June 2013, using the routing method, we conducted a visual inspection of the sites Slepyanskoy water system in our area. We selected five sites in the vicinity of houses. cleaning schedule
Revealed the following cleaning schedule facts Foam in water indicates the activity of bacteria in a given period of time - in the summer a lot of putrid particles. In sections 4 and 5 there is a gray-white coating on the surface cleaning schedule objects at the edge of the water that is in poor cleaning fecal waste water. In sections cleaning schedule 1, 2 fixed physical contamination coastline (recreational areas). In the pond roaches, perch, bullhead, carp. There are pike, carp, pike, and even carp. During our route we saw in the water perch.
We carried otsenkasummarnoy toxic contaminants cleaning schedule in water using indicator organisms - zoobenthos. Indicator species found 1 group - clams mussels, indicator taxa 2 groups: Crane fly larvae, dragonfly, Luzhanka, coil, crayfish and representatives of three groups capable of surviving in very dirty water - pond, pipe makers.
Held bio-indication of water quality with the help of zoobenthos showed cleaning schedule that the targeted areas there is little pollution. cleaning schedule Comparing the 2013 figures with 2006 (conducted a similar study) can conclude that the purity of the water Slepyanskoy water system on the territory cleaning schedule of Partyzanski district cleaning schedule has not changed. Environmental degradation has occurred.
For a more precise analysis of the chemical pollution of water in areas of the water system, cleaning schedule we investigated a sample for the presence of ions Pb 2+, CI -, Fe, NH 4+, SO 4 2-, NO 3 - potentiometric method. The analysis is conducted in the chemical laboratory of the Lyceum of BSU.
At the station 3 there is a concentration of lead ions equally
