Abstract: Amik Plain is one of the most important and productive agricultural areas of Turkey. It was aimed to determine nitrate (NO3 -), ammonium (NH4 +) and phosphorus (P) concentration and dissolved oxygen (DO) and salt content (SC) to assess its pollution levels in groundwater of Amik plain. A total of 42 groundwater samples were collected from wells and were analyzed for temperature (T), salt content (SC), dissolved oxygen (DO), ammonium (NH4 +), nitrate (NO3 −), and phosphorus (P). The temperature, SC, DO, NH4 +, and NO3 − parameters were measured in situ immediately. Phosphorus was determined using ascorbic acid method. Descriptive statistical analyses were calculated to characterize distribution of data of groundwater. Correlation analysis was also used to assess the possible relationships among the parameters. Result shows that the highest and lowest coefficient of variation occurred for P (PO4 3-) respectively. The T, DO, SC, NO3 -, NH4 + and P values in the groundwater ranged from 18.

Abstract: The consulting services are very important to the project life of construction projects. When owners select the contract type, they need to analyze the design work and the supervision work to be arranged. Is this service to be carried out by a single consulting firm having the required qualification and capacity? This research presents advantages and disadvantages of appointing the design consultant as construction supervision consultant in the construction industry in Saudi Arabia. A questionnaire was designed that comprised of five project phases including the project inception phase, project planning and design phase, project construction phase, project monitoring and control phase, and project closing phase. Responses of 101 valid questionnaires were collected from construction projects and analyzed by using the SPSS (Statistical Package for Social Sciences-21) for Windows software package. The results indicate that owners, consultants, contractors, and researchers strongly support
