    Groundwater in Local Development Strategies: Case of Izmir
    (IWA Publishing, 2018) Velibeyoğlu, Koray; Yazdani, Hamidreza; Velibeyoğlu, Koray; Baba, Alper; 02.03. Department of City and Regional Planning; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    This study takes into account groundwater in local development strategies of Izmir, in which rapid and uneven development has occurred in recent decades. Therefore, resilience thinking is needed in the future development of the city-region. To this end, the paper aims to make an analysis of recently completed asset-based local development strategies for Izmir city towards water resiliency. The methodology has two main steps. Firstly, by using spatial interaction analysis of peninsula and river basins, potential vulnerabilities and risks are indicated. Secondly, a stratified model of strategy evaluation is conducted by scrutinizing the existing layered approaches. Then, these models were applied to all strategic decisions including water resources and indicated a high level of consistency to achieve sustainable and resilient use of blue-green infrastructure in the future of Izmir’s metropolitan area. Local assets, including water resources, are the backbone of future development of the Izmir city-region. Therefore, usage of local assets in a multi-level perspective of strategy development needs to be understood. The stratified model denotes that special emphasis should be given to different river basins in different levels. This study illustrates that synergy management is needed between different layers of local development strategies, in which the role of urban and rural households is of the utmost importance.

    Groundwater Quality and Hydrogeochemical Properties of Torbali Region, Izmir, Turkey
    (Springer Verlag, 2008) Tayfur, Gökmen; Kırer, Tuğba; Baba, Alper; Tayfur, Gökmen; 03.03. Department of Civil Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    The large demand for drinking, irrigation and industrial water in the region of Torbalö (Izmir, Turkey) is supplied from groundwater sources. Almost every factory and farm has private wells that are drilled without permission. These cause the depletion of groundwater and limiting the usage of groundwater. This study investigates spatial and temporal change in groundwater quality, relationships between quality parameters, and sources of contamination in Torbali region. For this purpose, samples were collected from 10 different sampling points chosen according to their geological and hydrogeological properties and location relative to factories, between October 2001 and July 2002. Various physical (pH, temperature, EC), chemical (calcium, magnesium, potassium, sodium, chloride, alkalinity, copper, chromium, cadmium, lead, zinc) and organic (nitrate, nitrite, ammonia, COD and cyanide) parameters were monitored. It was observed that the groundwater has bicarbonate alkalinity. Agricultural contamination was determined in the region, especially during the summer. Nitrite and ammonia concentrations were found to be above drinking water standard. Organic matter contamination was also investigated in the study area. COD concentrations were higher than the permissible limits during the summer months of the monitoring period.

    A Health Risk Assessment for Exposure To Trace Metals Via Drinking Water Ingestion Pathway
    (Elsevier Ltd., 2009) Kavcar, Pınar; Sofuoğlu, Sait Cemil; Sofuoğlu, Sait Cemil; Sofuoğlu, Aysun; 03.02. Department of Chemical Engineering; 03.07. Department of Environmental Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    A health risk assessment was conducted for exposure to trace metals via drinking water ingestion pathway for Province of İzmir, Turkey. Concentrations of 11 trace metals were measured in drinking waters collected from 100 population weighted random sampling units (houses). The samples were analyzed in atomic absorption spectrometry for arsenic, and inductively coupled plasma-optical emission spectrometry for Be, Cd, Co, Cr, Cu, Mn, Ni, Pb, V, and Zn. Questionnaires were administered to a participant from each sampling unit to determine drinking water consumption related information and demographics. Exposure and risks were estimated for each individual by direct calculation, and for İzmir population by Monte Carlo simulation. Six trace metals (As, Cr, Cu, Mn, Ni, and Zn) were detected in >50% of the samples. Concentrations of As and Ni exceeded the corresponding standards in 20% and 58% of the samples, respectively. As a result, arsenic noncarcinogenic risks were higher than the level of concern for 19% of the population, whereas carcinogenic risks were >10-4 for 46%, and >10-6 for 90% of the population.
