SUMMARY: With new legislation regarding the waste sector we have studied changes in the average compostion of leachate from municipal solid waste (MSW) landfills from 1998 to 2002, compared to 2005 to 2010, based on standard monitoring programmes from six landfiills. As expected the concentrations of BOD and phosphorous have been reduced in the studied period, but not COD. Nitrogen and sulphur seem to have increased. As intended also Cd, Cr and Hg whereas Pb seems to have been increased. Also salt elements, such as Na and K, increased. Most organic parameters are reduced except for oil and pesticides. The treatment at the six locations seems to be as effective as expected

The collapse of the Soviet Union in the Central Asian countries has led to enormous challenges for them in ensuring a sustainable environment. Weak economies and lack of expertise in environmental sciences were important reasons for the Norwegian support to the environmental sector in this region. The State Forest Service of the Kyrgyz Republic and the Norwegian Forestry Group initiated the TEMP project, later renamed TEMP-CA, in the Kyrgyz Republic in 2004. Activities in the Republic of Tajikistan were included in 2007 and in the Republic of Uzbekistan from 2008. The forestry sectors in the Kyrgyz Republic and neighbouring countries in Central Asia, surrounding the Fergana Valley, are closely linked to the environmental and emergency planning sectors. Overgrazing and overharvesting have contributed to a dramatic decline in forest cover. The TEMP-CA project contributes to a better understanding of environmental problems and sustainable forestry in Central Asia. The TEMP-CA project has promoted institutional co-operation between Norway and the Central Asian countries as well as between different institutions both within and between the countries of Central Asia. Increased expertise for scientists, fieldworkers, laboratory staff and staff in different forest departments as well as institutional development in general are important outputs from the TEMP-CA project. The Umalak monitoring site in Tashkent region, the Republic of Uzbekistan, was the tenth of ten monitoring sites established in forests in Central Asia: 1: ”Kara-Koi” in the Osch oblast, the Kyrgyz Republic. 2: ”Sogot in the Jalal-Abad oblast, the Kyrgyz Republic. 3: “Dugoba” in Batken oblast, the Kyrgyz Republic. 4: “Besh-Tash” Talas oblast, the Kyrgyz Republic. 5: “Sary-Chelek”, in Jalal-Abad oblast, the Kyrgyz Republic. 6: “Navobod” in Sogdi oblast, the Republic of Tajikistan. 7: “Gauyan” in Batken oblast, the Kyrgyz Republic. 8: “Zaamin” in Djizak region, the Republic of Uzbekistan. 9: “Urumbash” in Jalal-Abad oblast, the Kyrgyz Republic. 10: “Umalak Teppa”, Tashkent region, the Republic of Uzbekistan.

Tracers can be used to monitor emisions of leachate from landfills, in order to detect hydrological pathways and to evaluate environmental pollution. We investigated the occurrence of the stable carbon isotope ratio (13C measured in dissolved inorganic carbon, or d13C-SCO2) and tritium (3H), in addition to parameters commonly found in relatively high concentrations in leachate such as chloride (Cl), organic matter (COD), nitrogen (Total and NH4-N), iron (Fe), electrical conductivity and pH. The sampling was performed at seven landfills in the south-eastern part of Norway during a period of 5 years. The objective was to evaluate the potential for tracing leachate in the environment with emphasis on groundwater pollution. By analyzing the d13C-SCO2 ratio in leachates, ground waters and surface waters the influence of leachate can be identified. The content of d13C-SCO2 varied from -5.5 to 25.9‰ in leachate, from -25.4 to 14.7‰ in groundwater, and varied between -19.7 to -13.1‰ in creeks. A comparison of the content of carbon isotope ratio with the concentrations of the compounds COD, electrical conductivity, Total- and NH4-N, Cl and Fe showed that d13C-SCO2 is a good tracer for leachate due to higher sensitivity compared to other parameters. The mean concentration of all the studied parameters was higher in the leachate samples, however, only the carbon isotope ratio showed significant differences between all of the groups strongly and weakly polluted and unpolluted samples, showing that it can be used as a practical tracer for lechate in groundwater and surface water. The carbon isotope ratioshowed strong correlation between nitrogen and electrical conductivity, and bicarbonate, but not with pH. Tritium was only found sporadically in low concentrations and is considered not suitable as a tracer at the sampled locations.
