Accurate and reliable laboratory results are an extremely important integral part of conducting scientific research. Many factors influence the obtained, including type determination method, accuracy precision measurements, equipment used for tests. This paper presents measurements heavy metal concentration in soil using two methods adding components into solution different types measuring equipment. The first method was hot digestion samples with a mixture concentrated HNO3 HClO4, after...

Abstract We discuss a study designed to elucidate the genesis and inflow conditions at riverbank filtration wells located on mountain river. This article seeks identify most important drivers of spatio‐temporal dynamics water flow in hyporheic exchange zone, natural disturbed by abstraction. In our we try contribute further understanding groundwater mixing with river zone. focus river/aquifer interactions scale reach an intake, especially unidirectional flows induced To understand these...

The paper presents an analysis of daily water consumption for household purposes carried out within one year in a selected rural household.The study was undertaken because so far the guidelines designing supply systems have not been updated very long time and needed verification.It involved comprehensive system measuring equipped with automatic readers data recorders.The research clearly showed that actual much lower than provided current guidelines, confirmed significant variability...

Abstract Applications of the Helium (He) method known so far consisted mainly 4 He measurements using a special mass spectrometer. for groundwater dating purposes can be replaced by total ( 3 + ) concentration because content ignored. The concentrations are very low and / ratios do not exceed 1.0·10 −5 in most cases. In this study, were determined gas chromatographic GC as an alternative to methods based on spectrometry measurement. used determination residence time circulation....

Aim of the study: Firstly, due to different sizes and spatial organization ski resorts, it is important determine whether there a local differentiation sound landscape within one resort. Secondly, continuous expansion infrastructure, essential develop methods for improving quality acoustic environment. It therefore necessary are differences between resorts. Material methods: The research we conducted consisted in measuring levels, inventorying various types events. examined despite...

Abstract We present the results of isotope measurements (δ 18 O, δ D, 13 C DIC and 14 C) chemical analyses (TDS, TOC, HCO 3 - , SO 4 2- Cl NO NH + Ca 2+ Mg Na K ) conducted on groundwater samples collected from deep Cenozoic aquifers. These aquifers are basic source drinking water at numerous localities within study area in northern Poland. Most O determinations characterised by low variability (i.e., > 70 per cent between -9.5‰ -9.2‰). In most cases tritium activity was not detected or...

Differences in the spatial variability of Na + and K ion concentrations groundwater sourced Southern Poland have been analysed.The study was based on selected hydrogeological environments differing lithology geometry aquifer rock voids.The hydrogeochemical background for ions determined various as well.The ranges obtained do not deviate significantly from observed other areas Poland.The analyses conducted indicate presence anomalous all often accompanied with elevated Cl -and SO4...

The study determines the impact of precipitation on amount wastewater flowing into treatment plant in Nowy Targ. research period covered years 2016 and 2017, which average daily inflows (during so-called dry period, i.e. days without wet with precipitation) were analyzed. was divided 5 characteristic ranges terms precipitation. It found that different intensity precipitation, rainwater (in total plant) from 14.2% to 32.5%. Taking account absolute values, it inflow 14361 18248 m 3 ∙d -1...

A real-space renormalization-group calculation of critical exponent correlation length and surface tension the square-lattice nearest-neighbor ferromagnetic Ising model is extended to cluster size b = 6. The extension allows a more reliable extrapolation for large sizes. Values approximate are obtained nearer exact value.
