Assessing the effects of water withdrawal for hydraulic fracturing on surface water and groundwater - a review

The interaction between groundwater and surface water plays an important role in the function of riparian ecosystems and sustainable water resource management. Hydraulic fracturing, an unconventional oil and gas well stimulation method, has increased dramatically in North America in an effort to exploit previously inaccessible shale oil and gas reserves. Hydraulic fracturing often requires several thousand cubic meters of water to fracture the source formations. Use of such a high volume of water has raised considerable public concern over the sustainability of this activity and the potential impacts on surface water and groundwater. This paper provides a review of the published literature addressing the effects of water withdrawal for hydraulic fracturing on surface water and groundwater. The potential effects of such withdrawal are: decreased volume of water in rivers, streams, lakes and aquifers; alteration of natural flow regimes; regional water shortages during periods of drought; creating conflicts with other water users in water-stressed regions; inadequate downstream water availability; reduced downstream water quality for human uses, due to less water availability for dilution; and degradation of habitat and aquatic ecosystem function, impacting local wildlife. This review demonstrates that relatively little attention has been paid to quantify and understand these interactions, and suggests that there is a significant need for further research in this area to address the currently limited availability of data.

Gospodarowanie wodami powierzchniowymi i podziemnymi w Polsce

Polska należy do grupy państw o najniższych zasobach wód odnawialnych w Europie. Przy zasobach określonych na poziomie 63 km3 na potrzeby gospodarki narodowej i ludności w 2008 roku wykorzystano około 17% dostępnych wód powierzchniowych i podziemnych. Głównym problemem powstałym przy zaopatrzeniu przemysłu i ludności w wodę jest występowanie obszarów deficytowych (środkowa i południowa Polska), w których gospodarowanie wodą bazuje jedynie na ujęciach powierzchniowych (Rzeszów, Katowice) bądź podziemnych (Kielce). Celem artykułu jest scharakteryzowanie wielkości poboru i zużycia wody na szczeblu krajowym, wojewódzkim i w miastach wojewódzkich. Zabiegi te pozwoliły na wyłonienie województw o największym i najmniejszym poborze wód w Polsce oraz pokazanie miast bazujących na eksploatacji wód podziemnych, wód powierzchniowych lub wód podziemnych i powierzchniowych.

Poland belongs to the group of nations with the lowest water renewable resources in Europe. From the resources specified on the level of 63 km3, for needs of the national economy and population in 2008, c.a. 17% of available surface water and groundwater were used. The main problem, which is formed at the water supply of industry and population, is occurrence of deficit areas (middle and southern Poland), where water management is based only on surface water intakes (Rzeszow, Katowice) or groundwater intakes (Kielce). A goal of the article is a characterization of the values of water withdrawal and consumption of water on the nation, voivodships and voivodship's capitals level. Those treatments allowed to present the voivodships with the highest and the lowest water withdrawal in Poland and to show the capitals, which are based on the exploitation of groundwater, surface water or groundwater and surface water.
