[email protected] ABSTRACT The paper presents the evaluation of the possibility to use the water from five quarry lakes located in County Strzelin for the purposes of agricultural irrigation. The evaluation was based on the guidelines provided by FAO and in PN-84/C-04635. The average values of water quality indicators were as follows: electrical conductivity – × -1 × -3 0.365 mS cm ; Sodium Adsorption Ratio – 0.75; Total Dissolved Solids – 233.9 mg dm ; water pH – 7.8; BOD5 × -3 × -3 – 1.6 mgO2 dm , while the average ion concentrations were: nitrates – 1.6 mgN-NO3 dm ; sulphates – 188.5 mg × -3 × -3 × -3 × -3 SO4 dm ; chlorides – 30.95 mg Cl dm ; sodium 22.6, mg Na dm ; manganese – 0.05 mg Mn dm ; and iron – 0.04 mg Fe×dm-3.
