The article identifies the hydrogeochemical environments controlling the chemical composition of groundwater in the Lódź agglomeration. The study was conducted with a different position of the groundwater table within: the Quaternary, Upper- and Lower Cretaceous aquifers. These aquifers are continuously exploited from a long time till present. The papers focuses on geogenic factors resulting from geological construction, lithology, circulation in the Lódź basin and anthropogenic factors associated with the change of the circulation system and the potential migration of pollution from the surface. The chemical composition of water from the Quaternary, Upper- and Lower Cretaceous aquifers was stable, without any anthropogenic changes. The hydrochemical inversion of water within the Cretaceous aquifers is the result of the different lithology of these aquifers and the variation in the way and magnitude of groundwater recharge.

Spring-fed fens in Wardzyń represent the rare group of alkaline mires supplied by artesian groundwater. Using multidisciplinary methods (including sedimentological, hydrometric and hydrochemical, pollen, macrofossil, malacological, geochemical, radiocarbon dating, and stable oxygen and carbon isotope analyses) we have been able to (1) reconstruct the main phases of spring-fed fen development, and to (2) determine the cause of Neoholocene groundwater ascension responsible for the mire inception. These phases are characterized by cyclic organic (peat) and carbonate (tufa) sedimentation associated with the Holocene fluctuations in humidity and temperature. The beginning of the activation of hydrological systems (involving the flow of confined groundwater of the Cretaceous aquifer) at Wardzyń occurred in the Subboreal period of the Holocene, after a long episode of decreased humidity initiated ca. 4.2 ka cal BP.

Rogóźno salt dome is one of the most recognizable diapirs in the Polish Lowland. Despite its shallow occurrence depth, increased salinity has not been detected in surface water. The presented hydrogeochemical research aimed at determining if there is the presence of increased geogenical salinity in the groundwater and shallow water. Increased geogenical salinity has not been detected in the Moszczenica River and the Czerniawka River, but were displayed in the Moszczenica River valley in the specific electrical conductivity (SEC) spatial distribution. Hydrogeochemical research indicated the presence of a higher mineralized water ascent in the north-eastern part of the dome. The presence of mixing of saline waters around the dome with fresh waters was determined. Ionic composition and hydrochemical indexes of waters sampled from different levels indicate that the saline structure is not completely isolated from surrounding waters. The dome structure is in contact with water from Upper Jurassic formation which influences the final water composition. Active anthropogenic processes partly mask the influences of geogenic salinity in the study area.

The chemical composition of water from two peatlands was investigated. Both peatlands, which are nature reserves, are located in central Poland in the Widawka and Rawka River valleys. The study concerned groundwaters, peat waters from different depths, and waters from draining ditches. The research permitted determination of the hydrochemical zoning of the peatlands resulting from the complex character of the water supply. The hydrochemical interpretation of surface waters outflowing alongside the ditches, in terms of their similarity to particular zones, provides an insight into the water-feeding structure of the peatlands. In the evaluation, hydrochemical indicators were applied, which have been used in hydrogeological studies. They are based on equivalent concentrations of the major ions: sodium, calcium, chlorides, and sulphates, selected from other hydrochemical elements by means of principal component analysis (PCA), conducted individually for each peatland. The analyses showed a high contribution of unconfined and confined groundwaters to the water supply, with clearly distinguishable zones, in terms of their transit through the structures of the peatlands.

W artykule przedstawiono analizę stanu czystości wód Moszczenicy, odwadniającej północno-wschodni fragment strefy podmiejskiej Łodzi na obszarze parku krajobrazowego Wzniesień Łódzkich. Ze względu na charakter wykorzystania jej wód głównie do rekreacji i hodowli ryb skupiono się na ocenie możliwości realizacji takich zamierzeń w warunkach postępującej antropopresji. Dedykowane badania przeprowadzono w czterech sezonach między 2009 i 2010 r. Wykazały one istnienie wyraźnych stref dopływu zanieczyszczeń, które ograniczają możliwości rekreacji i pogarszają warunki bytowania ryb. Przyczyną ich istnienia jest postępujący proces urbanizacji z poważnymi niedomaganiami w sferze infrastrukturalnej, prowadzący do degradacji stanu środowiska wodnego na obszarach objętych prawną ochroną.

The article presents a water purity analysis for the Moszczenica гіѵег, draining the north-eastern part of the Lodz suburban zone, on the territory of the Lodz Hills (Wzniesienia Łódzkie) landscape park. Due to the use of the rіѵег for recreational and fish farming purposes, the authors evaluated the possibility to carry out such activities in the progressing anthropopressure conditions. Dedicated research was being carried out for four seasons, be-tween 2009 and 2010. It proved the existence of distinctive zones of pollution inflow, limiting the possibilities of recreation and deteriorating the fish living conditions. The pollution is caused by progressing urbanisation process, with serious infrastructural malfunctioning, leading to the water environment degradation on the terrains protected by law.

This papers presents a picture of chemical variability of groundwaters in a region of high anthropogenic pollution, around the city of Łódź. The research as conducted in three groups of wells, all representing aquifres of potable waters within the Łódź hydrogeological basin. Two groups of wells chosen within the city area and one outside it, in a rural area. Research showed that the Łódź hydrogeological basin were presents the inversion type, regarding mineralization and chemical composition of water. Within Cainozoic rocks, inversion is caused by anthropopression, but in deeper aquifers geogenic processes play a domiant role. The same pattern of conditions varies also horizontally in each aquifer. Ca, Mg, Na and CI ions are of greater importance in the group of indicators ofhydrochemical variability of groundwaters. These elements have connection with pollution processes of groundwaters, visible in changes of hardness and salinity. Hydrochemical changes are also indicated by NO2 and NH4
