Abstract: Since the ocean dumping was banned in Korea in 2012, Korea government focuses on disposal of manure discharge in animal farms. Domestic animal manure can provide nutrients for crop cultivation and input for biogas production but, if managed in appropriately, can also have a negative impact on the environment. Due to the high pig concentrations and high off-farm disposal costs, on-farm treatment facility has been increased rapidly in Korea. Most of farms are used aeration treatment system while some of them are used with return activated sludge (RAS) treatment system. The objectives of the study were to provide information pig manure management practices and characterization of treated fertilized liquid manure (FLM) at different farms. Accordingly, FLM was subjected to analyze BOD, T-N, T-P, NO3-N, PO4-P, TSS, and NH3-N. BOD value in FLM produced from RAS enhanced farm was in a range between 265-1,945 mg/L with an average value of 1,006 mg/L, while the average BOD of aeration treated fa

Abstract: Seydisuyu Basin, which is located in the Eskişehir province of Turkey, contains very important agricultural lands. In this paper, the total organochlorine pesticide levels in groundwater of Seydisuyu Basin were investigated by determining Alfa HCH, HCB, Beta HCH, Gama HCH, Aldrin, Cis Heptaclorepoxide, Trans chlordane, Cis chlordane, Dieldrin, 44DDE, Endrin, 44DDD, 44 DDT, Metoxyclor and pesticides with Endosulfan in water samples. Groundwater samples were collected seasonally (2011 – 2012) from 29 wells from the Seydisuyu Basin. According to data observed, although groundwater of the Basin has I. - II. Class water quality in terms of total pesticide concentrations in general, organochlorine pesticide accumulations of some wells were higher than the drinking water limits specified by Turkish Standards Institute (TS266).
