Pump and fertilize, while removing nitrate the groundwater, can also reduce nitrate and pesticide requirement. In this study, we constructed groundwater models via HYDRUS 1D for one-hectare maize field in prevalent soils in Turkey and Eskişehir, Adana, Şanlıurfa, Düzce climates in Turkey, assessed the most likely promising conditions for pump and fertilize, and found that even in 50 mg/L nitrate concentrations, this process is beneficial, especially in Şanlıurfa similar climates (687 TL/year). Nitrogen leaching loss were more in sandy soils. Later, we modeled the atrazine and cypermethrin contaminated water irrigation, with also using leonardite as adsorbent to facilitate controlled desorption of pesticides. We found that using leonardite, one can both effectively immobilize the contaminant or dilute its concentration to its 1/5, 1/10 of applied concentration.

Modeling irrigation with nitrate contaminated groundwater Hatipoglu, Guray; Kurt, Zöhre (2019-03-01) An alternative method to treat the nitrate-contaminated groundwater under the agricultural fields while providing economic benefit is called pump and fertilize. Pump and fertilize, while removing the nitrate in the groundwater, can reduce nitrate and pesticide requirement. However, up to date, there are no studies evaluating the effect of this application under different soil/climate conditions. In order to apply this technology in the field and to determine its effect, a feasibility study needs to be perfo...
Modeling natural attenuation of petroleum hydrocarbons (btex) in heterogeneous aquifers Uçankuş, Tuğba; Ünlü, Kahraman; Department of Environmental Engineering (2005) Natural Attenuation can be an effective cleanup option for remediation of Groundwater contamination by BTEX. One of the important aspects of the methodology that has been recognized recently is that mass removal rates, the most important parameters used to determine effectiveness of the methodology, is controlled by groundwater flow regime, which to a large extent controlled by aquifer heterogeneity. Considering this recognition, the primary objective of this research is to quantitatively describe the relat...
Assessment of Dewatering Requirements and their Anticipated Effects on Groundwater Resources: A Case Study from the Caldag Nickel Mine, Western Turkey Peksezer-Sayit, Ayse; Cankara-Kadioglu, Cigdem; Yazıcıgil, Hasan (2015-06-01) Dewatering requirements of three open pits located in western Turkey and the impact of dewatering on groundwater resources were evaluated using a three-dimensional numerical groundwater flow model. The groundwater was modeled using MODFLOW software and the dewatering was simulated using the MODFLOW Drain Package. The drain cell configurations were determined by pit boundaries; invert elevations of drains corresponded to the bench elevations in the mining schedule, which varied dynamically among the three pi...
Optimal design and operation of land-treatment systems for petroleum hydrocarbons Kivanc, S; Ünlü, Kahraman (1999-04-22) Land treatment technology has been extensively used for the disposal of petroleum hydrocarbon containing wastes. Effective management of land treatment systems requires optimum design and operation of the system in order to achieve the fastest and most complete degradation of petroleum hydrocarbons without contamination of the environment. This paper describes a model that can be used for optimal design and operation of land treatment systems for petroleum hydrocarbon containing wastes. The model is compose...
ASSESSING RISK OF GROUNDWATER POLLUTION FROM LAND-DISPOSED WASTES Ünlü, Kahraman (1994-11-01) A stochastic modeling approach for the migration of contaminants in soil and ground-water is developed to assess the expected magnitude of contamination at receptors located downgradient from a waste pit. The model evaluates uncertainties in contaminant concentrations due to uncertainties in waste composition and hydrogeologic properties of waste sites, and determines the exceedance probabilities of a specified concentration level at receptor points using Monte Carlo (MC), first order (FO), and point-estima...
