Independent Environmental Assessment (Part 2)

However, we would like to draw attention to the quality of housing in the long term, which is largely determined by the following factors:

1. Ecological condition of the site where the facility is located.

2. The correctness of design decisions, including assessing the impact of residential complex (cottage town, village, etc.), which includes the object on the environment.

3. Quality construction and materials used.

This article deals with the first of these factors.

In developing the design documents designer is responsible for ensuring environmental safety of the project, environmental protection and rational use of natural resources according to GSN A.2.21. Minimum package of documents certifying the environmental condition of the site should include:

• Finally sanitarnoepidemiologicheskoy examination of the surface (in the presence of open water reservoirs) and groundwater chemical and hydrobiological indicators. The examination provides a measure of water pollution, and indirectly identify the sources of possible contamination (eg, drain drainage roads, landfill waste, farmland, etc.), as well as to assess the risk to health from using the lake for recreational purposes;

• Finally sanitarnoepidemiologicheskoy examination of water the main source of water supply (wells, urban or rural system of centralized water supply). In the cottage as a source of water are most commonly used well. The chemical composition of water from the wells is determined by the depth of the aquifer, but to use such water in the raw form is not recommended because of high salinity, high concentrations of ions of iron, manganese, calcium, etc.;

• Finally radiatsionnogigienicheskogo survey plots for construction (performance of gamma-radiation exposure dose equivalent equilibrium volume activity of radon). Radiatsionnogigienicheskoe survey to determine the level of radiation hazard area development for a decision whether to purchase or construction of the observed area of the property, as well as to determine the required radonozaschitnyh properties walling and develop appropriate technical solutions;

• Finally sanitarnoepidemiologicheskoy examination of the soil plot construction (replacing the natural soil imported - expert opinion of imported soil). Availability of soil heavy metals in concentrations exceeding the permissible, agricultural chemicals (such as organochlorines), pathogens, etc. imposes restrictions on the use of the soil in those or other purposes.

In addition to these documents, it is recommended to have information about:

1. Air quality:

• Monitoring data of ambient air. Monitoring is carried out the relevant services of the district, which form the statistical information about the state of atmospheric air;

• location of industrial facilities and transportation viaducts towards the wind rose. Toxic substances contained in industrial emissions and exhaust from road transport, subject to the air masses over long distances, settle on the ground, get into the groundwater and surface water;

2. Hydrogeological situation in the area:

• depth of groundwater, the presence of wetlands, the hydrologic regime of the reservoir (in the case of finding the section of the river or lake). For example, in reservoirs with low water exchange and low self-purification (closed water bodies with low flow velocity and limited power) possible stagnation, particularly the so-called "algal blooms" and the emergence of insects in summer;

3. On the territory of the site or in the vicinity of the following objects:

• Local treatment plants agricultural facilities or localities. At these sites there is a risk of accidents and falling raw sewage into open waters or ground water;

• active and closed graves of various types (landfills and solid waste (under the age of 150 years), burial grounds, cemeteries, etc.), storage or burial of agricultural chemicals. At these sites for a long time there is a decomposition of the buried material to the formation of highly toxic substances. Izzah lack of action to seal the burial takes place leaching breakdown products, followed by hitting them in the soil, groundwater and surface water. Decomposition of organic material in the open sites of burial may also be accompanied by the formation of unpleasant odors.

This information on environmental conditions of the site should contain a working draft of the construction. As practice shows, the draft is technically simple objects and objects of the type of building, which include cottages, as a rule, there is no section of the EIA (impact assessment on environment): developers do not bother to collect information on environmental aspects of the site and assessing the negative impact of construction on the environment. If you conduct a search of necessary information themselves, turning to local authorities, or looking for accredited laboratories, which could carry out the necessary tests and measurements, we can deal with annoying obstacles, overcoming of which requires considerable effort and time. Experienced specialists "Spano" will help with the search for information on environmental conditions of the site will make conclusions and recommendations on the basis of existing information, and if there is a buyer`s package of documents provided by the developer, to evaluate their credibility and will issue an opinion.
