Remediation of the harbor basin, including dredging of the sediments heavily contaminated with petroleum hydrocarbons and heavy metals is necessary to convert the harbor for civilian use. Abandoned pollution sources on land still continue to leach contaminants into the harbor basin. Our long-term research objective therefore is to identify transport pathways into the harbor sediments and to assess the in-situ degradation of pollutants in the system. The Liepaja harbor is treated as a complex system, where processes in the water column interact with the sediments and the nepheloid sediment boundary layer. For this research PAHs are used as the model organic contaminant. In this project the seasonal variation in biodegradation of PAHs is measured. This analysis is coupled with total bacterial production to establish the maximum degradation rate. With complex mixing of organic contaminants and need for understanding the ground water circulation it is difficult to determine the contaminant species. For this study a thorough assessment of PAH speciation has been used to determine the variation of sources. Variation in the PAH speciation is coupled with stable carbon isotope analysis to provide additional information on the range of sources in the harbor. Radio carbon isotope analysis of CO2 in the vadose zone from a site at the Naval Station Norfolk is introduced as an approach to survey natural attenuation in this region. The Liepaja harbor is the first contaminated harbor site to be remediated in Latvia. Knowledge gained within the project will help to develop the management of harbors and polluted sites in the country. At the same time, the Liepaja harbor can be regarded as a “typical” abandoned former Soviet army site. Experiences from the Liepaja harbor will be useful in future common efforts between the former Soviet Union and the US Navy.","PeriodicalId":287811,"journal":{"name":"2004 USA-Baltic Internation Symposium","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124850461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A number of larger rivers discharge their waters into this basin, transporting and depositing the residues of industrialised and agricultural developed regions. Nine riparian countries utilise the mostly sandy coastlines and the sea as living areas, tourist centres and as fishing grounds, which make a considerable contribution to the GNP of those states. Sea traffic has played a dominating role ever since in this region and most of the foreign im- and export goes that way, including the transport of hazardous goods, especially oil and oil products. There exist corridors for the safe navigation across the Baltic Sea which are crossed by a relatively high number of ferry lines between these countries. Since 1980 approximately one accident has occurred per year with a discharge of more than 100 t oil. In the case of such casualties even smaller oil slicks will reach one of the many coastlines, causing ecological and economical damage. Some relevant prevention and countermeasures have been and are discussed in the frame of the Helsinki Commission (HELCOM), where all riparian countries are represented, resulting in a number of recommendations. There remain open questions, however, connected to the safe transport of oil and oil products, to the environmental consequences in the case of casualties and to the control of oil spills. This paper will address some of these problems from the German point of view, based on recent German developments and the results of German research programs.","PeriodicalId":287811,"journal":{"name":"2004 USA-Baltic Internation Symposium","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130289793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
