Ecological Assessment of Local Water Resources on the example of Kamianets-Podilskyi City
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 100, Issue 1
Abstract
Disintegration of the state monitoring system of water resources in Ukraine has led to an increasing of their pollution level. Extra pollutant levels in potable water are a result of outdated water treatment technologies, the water distribution networks deterioration. Low quality of water negatively affects into life span of the Ukrainians. The situation with local sources of water supply is even worse. Therefore it was solved to study the water quality of dug wells in KamianetsPodilskyi sity, which is situated in western Ukraine. Water of these sources is used for drinking and household purposes; sometimes – for irrigation of a croft. For the assessment of local water sources quality it was done a seasonal monitoring of water composition parameters (permanganate index, total and carbonate hardness, dry residue, nitrate content). It was analyzed the water samples of two sources of decentralized water supply. It is established that the water of both boreholes is characterized by a high level of anthropogenic pollution. Their markers are a high nitrates and dissolved organic compounds content. It is observed the major difference between nitrates level. Water of the 1st well includes extremaly high concentrations (untill 180 mg/L), while the 2d – near 40 mg/L. This fact means that the main source of nitrates is a household pollution. Due to a significant excess of sanitary and chemical safety and quality indicators, these water sources cannot be used for drinking consumption. There are also certain risks when using these waters for irrigation (bio-growth, deposition of hardness salts on the surface of the water distribution network). According to the ecological classification, the water of local wells should be classified as very contaminated.
