This paper presents results of the study on preferences of inhabitants of the Częstochowa Region in Poland in the fi eld of groundwater protection. The choice experiment (CE) method was applied, and willingness to pay (WTP) for improving groundwater quality through the development of sewerage systems was assessed. The results indicate that there is substantial WTP for water quality improvements. Households are willing to pay 18.25 PLN (4.43 EUR) per month to remain pol-lution at the maximum safe level according to EU regulations (reducing nitrate concentration in groundwater to 50 mg∙L-1). Our results add to the expanding literature on the valuation of water resources and can be useful in analysis of investment eff ectiveness, in the valuation of environmental costs and benefi ts related to improvement or deterioration of groundwater condition, and in the pricing policy debate in terms of fees and prices for water and water services.

Niniejszy artykuł przedstawia wyniki badania preferencji społecznych mieszkańców w regionie częstochowskim w zakresie ochrony wód podziemnych. Za-stosowano metodę wyboru dyskretnego (CE), oszacowano gotowość do zapłaty (WTP) za poprawę jakości wód podziemnych przez rozwój systemów kanalizacyjnych. Otrzymane wyniki wskazują na znaczącą WTP za poprawę jakości wód podziemnych. Gospodarstwa domowe są skłonne zapłacić 18,25 PLN (4,43 EUR) miesięcznie za obniżenie zanieczyszczenia do maksymalnego bezpiecznego poziomu określonego przepisami UE (zmniejszenie stężenia azotanów w wodach podziemnych do 50 mg∙L-1). Wyniki pracy uzupełniają stale rosnącą literaturę na temat szacowania wartości zasobów wodnych i mogą być przydatne w analizach efektywności inwestycji, w wycenie kosztów i korzyści środowiskowych związanych z poprawą lub pogorszeniem stanu wód podziemnych, a także w dyskusji nad polityką cenową w zakresie opłat i cen za wodę i usługi wodne.
