Dynamics of physicochemical parameter concentrations in the Graniczna Woda stream water

Abstract

The paper presents variability of physicochemical parameter concentrations and determined the potential and chemical status of water in the Graniczna Woda stream, the right bank tributary to the Stoła River. The stream catchment area of 41.5 km 2 is covered mainly by forests. A lowland stream flows through part of the Upper Silesia Industrial Region through three districts. A biological-mechanical municipal sewage treatment plant operates in the area of Miasteczko Śląskie, as well as a factory sewage treatment plant of Zinc Plant. The data base used in the papers consisted of the results obtained from the Provincial Inspectorate of the Environmental Protection in Katowice, monthly analyses of water samples collected in the years 2009-2013 in the control-measurement points located by the mouth of the Stoła River. 34 physicochemical indices were analyzed in the paper. Statistically significant upward trends were determined over the period of investigations for values of electrical conductivity (EC), total suspended solids, Cl, SO 4 , NO 2 -N and Zn in the stream water. Statistically significant downward trend was noted for total hardness. It was stated that both the potential and chemical status o the stream water were below good. Exceeded limit values for quality class II determined for oxygen and organic indices (chemical oxygen demand COD-Mn, total organic carbon TOC), salinity (EC, SO 4 , Cl, Ca, hardness) and biogenic indices and substances particularly harmful for aquatic environment (Zn, Tl) as well as exceeded allowable heavy metal concentrations may evidence a constant inflow of heavy metals to the aquatic environment of the Graniczna Woda stream from municipal and industrial sewage.

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

“…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 concentration of solutes greatly affects oxygen’s water solubility, and thus the ability of water to assimilate impurities.…”

“…The nitrate concentrations of the Szreniawa river waters, depending on the season, ranged from 0.13 to 13.46 mg/dm 3 (Kowalczyk and Kopacz 2019). The comparison of changes in seasonal values of pollution indicators in rivers showed that the highest concentrations of nitrate nitrogen were recorded in summer (Kowalczyk and Kopacz 2019, Żarnowiec et al 2017, Kiryluk and Rauba 2009. Observed in our study the lowest pollution with nitrogen compounds occurred in the third quarter of the year in the parts of the catchment located at points of agricultural use.…”

“…On the other hand, livestock farming areas were documented to increase the concentration of free ammonia in the air [9,10], which may further affect NH 4 + levels in rainwater [11]. Nutrient enrichment is also accelerated by municipal activity, as septic tanks, in turn, are responsible for phosphorus, organic nitrogen, and ammonium releases to the aquatic environment [12][13][14]. Finally, another source of biogenic pollutants in water is outflows from landfills [15,16].…”
