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...

This study presents the behavior of nitrate in recharge zone Tursko well-field (south Wielkopolska, Poland). The presence a contaminant plume derived from land drainage systems was documented. contamination is reflected mainly by high concentration (>80 mg/l). It documented that migrates aquifer along flow path source to well-field. factor retards migration bacterial denitrification. As result denitrification, decreases systematically lines, but other parameters—products denitrification...

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....

The concentration of helium in groundwater may be a good environmental tracer for dating hydrogeology.In this work, we present chromatographic method simultaneous analysis helium, neon, and argon from single sample.Proper use tracers purposes requires the knowledge recharge temperature system excess air.Both parameters can determined by measuring neon groundwater.The lowest is 4.8 × 10 -8 cm 3 STP /gH 2 O at sea level • C. In view deficiency suitable detector with limit detection O,...

Na temat warunkow hydrogeologicznych niecki lodzkiej wystepują odmienne poglądy, szczegolnie dotyczące zasilania tego systemu wodonośnego w rejonie aglomeracji lodzkiej. Badania zmienności stezen znacznikow środowiskowych migrujących do z „gory” i „dolu” pozwolily na wprowadzenie dyskusji nowych wynikow weryfikacje dotychczasowych koncepcji krązenia wod tej strukturze wodonośnej. Wiek podziemnych poziomie K2 ksztaltuje sie zakresie 4600−12 100 lat, zalezności od glebokości oprobowanej studni...

We discuss a study that aimed to understand the genesis and inflow conditions of abstracted water by intake with induced infiltration located at mountain river. A simple approach based on combination two research techniques was used: two-component mixing modelling studies variability concentrations environmental tracers in dynamic test. This is versatile, easy apply modify, can be good method for controlling surface/groundwater interactions. used gas because exchange dissolution gases...
