Chapter
Electrokinetic remediation (EKR), also known as electro‐reclamation, electrokinetics, or electrokinetic soil processing, is a promising technique used to treat contaminated soils and sediments. EKR applies low‐intensity direct current to contaminated porous matrices including soils, sediments, and sludge. The electric field enables assembling and t...

The pollution of natural waterbodies with landfill leachate from dumpsites is a severe environmental issue all over the world. Karadiyana semi-controlled dumpsite in the Western province of Sri Lanka is one of the largest dumpsites in the country. The leachate generated in the dumpsite directly flows into Meda Ela canal which is a tributary of Bolg...
Article
Landfill leachate has created significant environmental issues throughout the world. Most of the developed countries have strict guidelines for the management of solid waste landfills as opposed to the open waste dumps commonly used in developing countries. Karadiyana is an open dumpsite which is in operation for nearly 20 years, located in the Wes...
Conference Paper
Water pollution occurs from open dumpsites, typically producing leachate with a very high content of organic matter. The objective of this study is to identify the containing organic matter of landfill leachate produced by Karadiyana open dumpsite, Sri Lanka and to relate it with the measured physicochemical parameters such as BOD/COD ratio, COD an...

Lakes, reservoirs, rivers, and aquifers are important freshwater sources for basic human needs such as drinking, sanitation, and agriculture. The anthropogenic influences on the natural environment, especially on freshwater resources, have increased dramatically during the last few decades. Eutrophication and pollution are major threats to many of...
Conference Paper
Leachate from solid waste landfills is a significant environmental issue throughout the world. Most of the developed countries have strict guidelines for solid waste landfills as opposed to the open solid waste dumps in developing countries. Karadiyana is located in Western province, Sri Lanka having a total area about 25 acres. Several Local Autho...

Coral reef are one of the most valuable coastal ecosystems, yet they are under various threats. Present study was to investigate the growth of Acropora Formosa fragments in in-situ coral nurseries of Matara Pollhena reef located on the southern coast of Sri Lanka. Study was conducted between April to November 2014. Eight different sites representin...
