The usage and exploitation of water resources brings the people to problem of providing pollution free environment. It could be achieved when exploiting technology is safe and specially designed under environment requirement. Some examples illustrate the necessity of such approach. Sea polluting by damaged oil tankers (Exxon Valdez Tanker $ 6.0 Billion in 1989 and Prestige Tanker $ 4.0 Billion in 2002). Sea polluting by damaged BP Deepwater Platform 2010 in Mexican Gulf – over$ 42.0 Billion. Similar examples could be mentioned in other areas such as oceanography/marine chemistry, biology, etc. The proposed Special Issue would accelerate the exchange of advanced technologies and implementation of best science solutions in practice.
