Roles

Nagib Benmusa is one of the staff members at the department of 6 faculty of 1. He is working as a since 2012-04-08. He teaches several subjects in his major and has several puplications in the field of his interest.

Careers

Faculty member at the University of Tripoli, Department of Geology, August 2010 - until now. He teaches physical geology, historical geology, field geology, and geomorphology.

 Participation and supervision of geological field camps.

 He supervised students’ graduation projects, curricula, and academic quality programs.

  He served on numerous educational committees including Academic Development

Research Interests

Attended and participated in over 60 local and international conferences on geology, drinking water replenishment projects, water quality standards, water treatment, desalination, and the environmental and health impacts of water pollutants from 1987 to 2010. Managed and supervised all drilling operations at WRM, resulting in the establishment of four new well fields. These operations included drilling high-capacity general supply wells, recovery wells, extraction wells, monitoring well water quality, pressure gauges, and test holes. Drilling methods included reverse circulation drilling, mud rotary drilling, cable tool drilling, air rotary drilling, dual rotary drilling, core drilling, and borehole drilling. Prepared well drilling contract specifications, well construction designs, impact studies for well spacing, and obtained all necessary permits in compliance with government and private regulations. Worked with environmental agencies to assess the environmental impact of drilling operations, subsequent treatment, and site restoration. Familiar with various types of well casings including carbon steel, stainless steel, and PVC. Provided recommendations for proper equipment selection to the planning and engineering department based on analysis of groundwater layer testing. Completed well reports submitted to the Arizona Department of Water Resources. Extensive experience in various methods of groundwater layer testing such as pumping tests, injection tests, packer tests, borehole imaging, and monitoring wells. Analyzed groundwater testing data collected by field engineering technicians. Used the data to determine hydraulic properties of the groundwater layer, such as permeability and storage capacity.

External Activities

As an advisor to the Supreme Council for Sustainable Development and the Development of the Bio-Technology Center, I provided guidance and expertise on various projects related to water desalination. Specifically, I served as an advisor for the Gadamis phase of the Great Man-Made River project. In addition, I worked as a consultant for the municipality of Tripoli, focusing on water desalination.

During my tenure in Tucson, I worked in water management, planning, and engineering. From April 1985 to August 2010, I held the position of Project Manager/Hydrologist at the Water Resources Management (WRM) department. In this role, I managed the entire Water Quality Monitoring Program (WQMP) within WRM. This program involved scheduling and overseeing sampling of public supply wells (existing and new), monitoring wells, pressure gauges, transmission lines, reservoirs, storage tanks, pressure tanks, booster stations, and water treatment plants. Sampling techniques included well pumping, bailers, grab sampling, and composite sampling. I received and conducted technical reviews and evaluations of water quality results.

I conducted quality analyses for the new water source of the municipality, monitored wells according to the standards of the Environmental Protection Agency and the Arizona Department of Environmental Quality (ADEQ) for drinking water. I provided verbal and written recommendations to municipal government subsidiaries and consultants.

I served on recruitment committees for the US Geological Survey (USGS) and the Tucson and Arizona Water Resources Management.

From early 1992 to mid-1994, I extensively participated in the Central Arizona Project (CAP), where Colorado River water was delivered to the Tucson Water Treatment Plant (TWTP) through an open canal.

I was involved in addressing the issue of water corrosion at the TWTP, as well as addressing other water quality problems in individual wells, well fields, storage tanks, and reservoirs. These issues included elevated levels of nitrates, arsenic, lead, sulfates, trichloroethylene, 1,4-dioxane, polychlorinated biphenyls (PCBs), trihalomethanes (THMs), acidity, total dissolved solids (TDS), hardness, carbon dioxide, pesticides (insecticides and herbicides), hydrocarbon pollution, naturally occurring radioactive materials (NORM), antimony, phthalates, radon, microorganisms, algae, and cyanobacteria. I reviewed and evaluated technical and assessment reports prepared by consulting firms and participated in investigations with ADEQ and EPA to determine the impact of benzene leakage from underground storage tanks on local and regional groundwater quality.

From 1986 to 2010, I actively participated in drinking water replenishment projects as well as wastewater projects. Stemming from these projects, I conducted borehole drilling tests on experimental wells and regional sampling in wells for water quality purposes.
