I work at the Faculty of Applied Sciences, University of Sri Jayewardenepura, Sri Lanka as an Academic and Researcher. My focus is on pollution monitoring and remediation in soil and water. Special attention is given to landfill leachates, nutrients and toxic metals. I work with many collaborators from different countries including India, South Korea, Japan, Denmark, Australia and USA as well as in Sri Lanka. Other than research, I prefer writing about science in Sinhalese, mother language.

Special Issue on Cross-cutting approaches for tackling water security of the Anthropocene
Water crisis exists in discrete sectors inducing water quality degradation and water shortage, which have led to considerable economic losses and social conflicts in communities on every continent. These discourses on water has prompted the concept, “water security”. Water security has emerged as a critical issue of concern in global, regional and national discussions and helped in conceptualization of SDG 6 in the UN Sustainable Development Framework. The Special Issue (SI) is intended to bring the focus on water availability, management, governance, water quality, biotic or abiotic emerging contaminants and policy development in the Anthropocene, and particularly the integrated, cross-cutting approaches to tackle them. We want to encourage the submission regarding newer global trends of water management, wastewater reuse, monitoring emerging contaminants, and their novel integrated technologies for mitigation strategies and policy development for the future water sustainability in the Anthropocene. SI will collate a number of studies that consider topics including:
+Occurrences of viruses and PPCPs +CSO overflow and surface water quality +Innovations for water quality management +Nanomaterial and wastewater treatment +Redox process and geogenic contamination +Decentralized water supply and stakeholder awareness +Emerging contaminants in agricultural runoff +Urban water vulnerability and resilience +Real world water sustainability analyses +Evaluation of sewer leak in groundwater using molecular marker +Incubation Experiments of Groundwater Hydrologic +Modeling and water availability +Droughts and floods: Problem and Perspectives +End-water use and its application for urban water crisis +Per and Polyfluorinated compounds in water and their removal +Submarine groundwater dischargeWater security and CKDu +Biochar efficacy for contaminant removal +Novel, low energy consumption processes for wastewater treatment +Coastal Water Issues

Arsenic and fluoride removal from water using bone char
Globally, over 200 million of people are affected by fluoride in drinking water and a similar number by arsenic at toxic levels; in some cases both contaminants occur together. Our research aim is to investigate the efficiency of modified bone char for removing As(III), As(V) and F- from groundwater. The scope of the project is to investigate the characteristics and efficiency of bone char and its composites produced from lamb bone in removing As(III), As(V) and F contaminants from water. This research will investigate: How do the chemical and physical characteristics of the bone char and its composite facilitate the adsorption of As, and F- individually and in co-adsorption, and contaminant removal from water and what are the impacts of co-existing anions on the ability bone char to remove As and F- from water?
Mechanistic understanding of arsenic and antimony removal in mining and rice ecosystems using biochar
Elevated concentrations of toxic metal(loid)s; arsenic (As) and antimony (Sb) in environmental, biological and geochemical systems originating from natural, geological and anthropogenic sources are of significant global concern. The Sb released from mostly geogenic sources is of similar toxicity as As and can negatively impact on both environmental and human health. Therefore, respective accelerated research on speciation, bioavailability, toxicology and remediation are essential for providing the growing world population As and Sb -safe freshwater and food. Hence, this research project investigates the mechanistic and kinetic related aspects on applications of invasive plant derived biochar for the immobilization of toxic species of As and Sb in mining and rice ecosystems in Australia.
Thio-arsenic complexes and the environment: Formation, speciation and quantification
Arsenic (As) and sulphur are often interrelated in their biogeochemical cycles. Arsenic species where the oxygen-bonded As is substituted by sulphur are known as thio-arsenic compounds which are considered as the third major group of naturally-occurring As species. Many key aspects of thio-As related compounds including, geochemistry, mobilization mechanisms, and quantification in different environmental systems still remain poorly understood. Hence, this research project aims to investigate the formation mechanisms, speciation and quantification of thio-As complexes in mining and paddy field environments in Australia.
