Water Quality Assessment Report - ZAI: Task 3 – Zai Water Treatment Plant Project

for the United States Agency for International Development under the Global Architect - Engineer Services II IDIQ contract. The report assesses the water quality of the Zai Water Treatment Plant, which serves the Wadi Arab Water System II in Jordan. The report begins with an introduction to the project, which includes a summary of the USAID Jordan Water Infrastructure initiative and the scope of work for Task 3, the expansion of the Zai Water Treatment Plant. The report also acknowledges the contributions of various stakeholders, including the Ministry of Water and Irrigation and the Water Authority of Jordan. The report is organized into four sections. Section 2 provides an overview of the Jordanian water quality standards, including physical characteristics, biological characteristics, inorganic chemical substances, organic pollutants, disinfectants, and radionuclides. The report also discusses aesthetic water properties, such as taste, odor, and color. Section 3 focuses on the raw water quality of the Zai Water Treatment Plant, including turbidity, total organic carbon, coliforms, and applicable water treatment processes. The report also examines extreme water quality events and compares the raw water quality to historical data from the KAC water system. Section 4 assesses the treated water quality of the Zai Water Treatment Plant, including turbidity, nematodes, chlorine, chlorite, total organic carbon, trihalomethanes, and applicable water treatment processes. The report also compares the treated water quality to historical data from the Zai Water Treatment Plant. The report includes several figures and tables that illustrate the water quality data, including turbidity, total organic carbon, and trihalomethane levels. The report also provides a list of abbreviations, units, and references. The report concludes that the Zai Water Treatment Plant is capable of producing high-quality treated water that meets the Jordanian water quality standards. However, the report also identifies areas for improvement, including the need to optimize the water treatment processes and to address extreme water quality events. The report was prepared by Mark White and reviewed by Al LeBlanc and approved by Rick Minkwitz. The report was submitted to USAID on November 5, 2018, and was made possible by the generous support of the American people through the United States Agency for International Development. The report provides a comprehensive assessment of the water quality of the Zai Water Treatment Plant and identifies areas for improvement. The report is a valuable resource for water treatment plant operators, regulators, and stakeholders who are interested in ensuring the quality of drinking water in Jordan. The report's findings and recommendations are based on a thorough analysis of the water quality data, including turbidity, total organic carbon, coliforms, and other parameters. The report also examines the impact of extreme water quality events on the Zai Water System and provides recommendations for improving the water treatment processes. The report's conclusions are based on the analysis of the water quality data and the examination of the water treatment processes. The report recommends that the Zai Water Treatment Plant operators optimize the water treatment processes to improve the quality of the treated water and to address extreme water quality events.
