Ecological characteristics of underground aquatic ecosystems of the Perm region

Meshchurova T. A., Aksenova V. M.

The article presents an analysis of materials for monitoring the state of groundwater on the territory of Perm Region. It is established that during the study of water from underground sources of centralized and non-centralized water supply, samples that do not meet sanitary requirements are recorded annually. The share of water samples from underground sources of centralized water supply that do not meet hygienic requirements for sanitary and chemical indicators has increased over the past 4 years by 2020. Water from underground sources of non-centralized water supply in rural areas of the Perm Region is better in quality. The main reason for non-compliance of water with sanitary and epidemiological requirements remains the absence of sanitary protection zones of sources. It is noted that emissions of pollutants into the air, waste storage, wastewater discharges of multidisciplinary, agricultural and municipal facilities contribute to changes not only in surface waters, but also underground.
