Abstract
Increasing public concern about deleterious effects of contamination on the environment and human health has led to legislative actions aimed at controlling and regulating the emission of potential contaminants into the environment, but there is still a plethora of territories historically contaminated with different contaminants within the territory of Latvia.
The purpose of the present study is to give an overview of the formerly and presently contaminated areas and give some recommendations for remediation. 242 first category contaminated territories (the contamination exceeds the acceptable normative 10 times or more) are mentioned in the National Register of Contaminated Territories, a lot of them are known as contaminated with hazardous contaminants such as heavy metals, oil products, organic compounds and other contaminants in different amounts and concentrations. An overview of soil contamination in Latvia is provided, the planned and recommended research, as well as the planned remediation in pilot case studies, are described, giving a review of the historical contamination situation and of applications of the planned remediation technologies.
