The Effect of Agricultural Activity on of Water Quality in the Jasienianka Flysch Stream

Abstract

Abstract. The paper presents the results of hydrochemical research conducted on the Jasienianka flysch stream, a left bank tributary to the Biała Tarnowska river. The submontane catchment of the stream, with area of 94.40 m 2 is situated in the Malopolska province. The stream catchment area is covered mainly by agricultural lands (68.3%) and to a lesser degree by forests (25.5%), built-up and urbanized areas (6.2) located along the banks of the Jasienianka and its tributaries. The investigations were conducted in 2014. 21 selected physicochemical indices were determined in the stream water at five control-measurement points situated along the 13 km long stream reach. Along the analyzed stream section, only the water temperature, dissolved oxygen, BOD 5 and N-NH 4 + allowed to classify the waters to quality class I (maximum potential), whereas ChZT-Mn, EC, SO 4 . The assessment of water usable values revealed that it may be used for supply of water intended for human consumption only in the upper and middle reach. The Jasienianka did not meet the requirements for a natural habitat salmonid fish along its whole length because of high NO 2 -concentrations.

Evaluating the applicability of MESS (matrix exponential spatial specification) model to assess water quality using GIS technique in agricultural mountain catchment (Western Carpathian)

“…It is an indicator of contamination of economic wastewater, where pathogenic bacteria may be present (Moore and Langner 2012 ). Without the accompanying nitrites and nitrates, the presence of ammonia itself in the water shows nearby and quite recent water pollution (Policht-Latawiec and Żarnowiec 2017 ). Organic and mineral fertilization promotes water contamination with nitrates (Żarnowiec et al 2017 ).…”

“…The results of the pilot study were compared with the results of other authors dealing with the subject of bacteriological risk of drinking water. This topic was addressed by, among others, Policht-Latawiec et al (2017) for the Besko water reservoir (Poland, Sub-Carpathian Province) intended for collective water supply to the population. A similar trend was demonstrated based on the results of the research from 2004-2014.…”

“…In case of drainage basins of lowland and submontane rivers, the water quality is usually affected by agriculture which contributes to an increased content of biogensin rivers. A high concentration of phosphorus and nitrogen has a huge negative impact on the water quality in rivers and regions through which rivers flow, causing eutrophication processes (Policht-Latawiec et al, 2014;Bogdał et al, 2016;Bogdał et al, 2019).…”
