ILES

... stands for Independant Laboratory for Environmental Studies and its website presents first results of case studies and various investigation programs that have been carried out in the past, at present time and those directed to upcoming problems of the future. The focus is on water ecology, drinking water and waste problems in Ukraine.  Aim of this website is to provide independant information that is difficult to obtain from other sources in English language. This information supply is thought to provide some historical findings, collected in an archiv, that can be used for comparison with the present situation. Principles of methods that have been used are additionally described. The website language is English, a few articles are also in Russianand Ukrainian.

Historical data: rivers

 

Rivers and their catchment are under pressure in Ukraine. Soil, groundwater, surface waters and drinking water have been investigated since Ukraine became independant.

Examples for small city rivers: (s. photos made in 2007)

R. Darnitsa, Kiev,  exit of a 5 km underground tunnel

River Darnitsa waste dumping place

R. Siretz, Kiev region Obolon

Smaller rivers (as on the photos above) in and around Kiev are loaded with pollutants from storm water and soil contamination. The main problems are soil erosion that damage or wash away organisms (river biocoenosis), use of salt during winter and chlororganic compounds that are used commercialy and privately and end up in the streams. In some places nutrients from private gardens have an additional impact, especially when the rivers are divided into a series of fishponds or reservoirs. Often waste is dumped into the rivers themselves or they are flushed into the river by heavier storm events. A short compilation of earlier studies is shown here.

The problem of Salinisation and Chlororganics (AOX) in Ukrainian rivers is presented  here. The data shown are from earlier studies but as similar works are still rare in Ukraine they are shown here.

Pesticides are increasingly applied, controls of water contamination are missing

The bigger rivers suffer from salinisation (drainage from mining) and eutrophication caused by waste water and agriculture. The problems have been investigated in Ukraine ( River Inguletz and Dnepr) and Russia (River Ob).

Finally we present  big river systems that have been investigated in former years.

Historical data:: drinking water sources

In most cities, surface waters are the main source of drinking water. Treatment and disinfection of this water are rather problematic: toxic effects on water organisms (En / Ru) and formation of byproducts that have negative impacts on human health.

 

 

 

 

 More than 260 deep artesian wells have been drilled in Kiev 5 to 10 years ago to provide alternative drinking water; here people can fill up their daily ration; the only question is:  do they always provide safe drinking water ? ......  In some cases doubts are justified.

Update: recently, most od those wells have officially been closed !!!

 

 

 

 

 

 

 

 

Ukrainians, living in villages, are also at risk: water from shallow wells is often enriched with nitrates and pesticides.

Recent years GIS-based river basin studies                

   Summary of methods

Integrated river basin management includes whole river basins with their landscapes, vegetation cover, soil types, groundwater and surface  waters. The whole river basin with all its relevant components can be summarised in a computer model based on a GIS (Geographical Information System).

The method is explained in English and in Ukrainian language:
