Our research topic also links to the concept of the 4 stages of critical risk analysis … Therefore, it is important to have both accurate measurements of these impacts and effective mitigation techniques. This report examines effects on the marine environment associated with the construction and long-term operation of seawater desalination plants. This report is part of a series launched in 2012 identifying the key outstanding issues for desalination in the state: cost and financing; energy use and associated greenhouse gas emissions; and marine impacts. Pumping water over these membranes requires lots of energy and therefore, lots of emissions. Desalination projects require an environmental impact assessment (EIA) study to determine the impact the project can have on the environment. Reliance on desalination for drinking water is projected to increase globally. Environmental impact and impact assessment of seawater desalination. Furthermore, severe ecosystem damage may be caused if water abstraction rates exceed natural renewal rates, leading to a depletion or salinization of stocks … Environmental impacts of desalination plant operations From: superfund.ciesin.columbia.edu The National Research Council (NRC) 2008 analysis identified three major categories of environmental impacts associated with operation of a desalination plant that are relevant to the Haverstraw Bay, NY project proposed by United Water New York: (1) Impacts associated with the water intake; (2) Impacts … Without careful planning, the associated increase in water withdrawal has the potential to adversely impact aquatic life in the vicinity of these intakes. Project Researchers & Authors: Harim Lee, Andy Meechukant, Gabriela Alcala, Alexander Sanchez, and Alex Forest. However, desalination as any human-based process has resulted in many impacts on the environment. Selim Riveill. The EIA considers all environmental parameters and criteria. However there are effects more specific to desalination plants such as impingement and entrainment of marine organisms due to the intake of seawater, the Green House Gases GHG) The goal of our research topic is to weigh the pros and cons of desalination and find out the impacts of desalination on the environment. The environmentalists argue that desalination is relatively expensive, pollutes the environment and long term impacts of the pollutants are yet unknown. Additionally, the removal of salt from water results in a byproduct of saline brine: a highly concentrated salt solution that is pumped back into the ocean and can cause damage to ocean … desalination plants even though they have opposed by environmental groups. Desalination of seawater accounts for a worldwide water production of 5000 million m³/year. Almost 16,000 desalination plants worldwide produce bigger-than-expected flows of highly salty waste water and toxic chemicals that are damaging the environment, a U.N.-backed study said on Monday. 2. When it goes through the filtration steps necessary to remove the extra sodium from the liquid, the water becomes usable for agriculture, industrial needs, and for drinking purposes. This white paper focuses on impacts of major desalination projects and their mitigation and investigation by environmental impact assessment. It evaluates the potential impacts to air, land, and marine environments and also proposes mitigation measures to reduce environmental impacts. Environmental Impacts Assessment There many potential environmental impacts of desalination process in GCC countries similar to any other industry.
