The article deals with water quality assessment in the upper Vltava basin, i.e. as far as Solenice. Both linear and areal investigations have been made. The Czech State Standard 757221 water quality classification has been used. The areal results are based on the balance of specific substance load. The research has been carried out in close cooperation with Wassergutestelle Elbe Hamburg within the framework of the Elbe Project. Basic data from 23 hydro-stations on Vltava (period 1990 - 1994) was provided by the Czech Hydrometeorological Institute.

Quality Assessments

Lake water is important to all life and surroundings with multiples benefits and forms either in natural or man-made conditions. One of the most well-known tools for assessing the water quality is Water Quality Index (WQI) and widely used including Malaysia. Lake water quality should be represented in lucid way like other surface water regarding to the WQI standards for water quality assessment on lakes. This paper aims to review on lake water quality classification and its uses based on WQI standards in Malaysia. In this review, the uses of WQI for assessing the lake water and functioned of lakes are discussed. Results on pH from 5.0 to 9.2, BOD in mg/l from 0 to 180, COD in mg/l from 5 to 150, SS in mg/l from o to 1800, DO in mg/l from 0 to 8 and AN in mg/l N from -1 to 26. Variety of numbers is due to different loading of pollutions and location. With used of WQI on lake water quality assessments, further action can be taken for the uses on water resources by maintaining the quality. It also will broaden the uses of lake water as alternative of water resources in Malaysia.

The water quality assessment of Arges River and its tributary Dambovita River is presented in this paper as second part of an extended study on the evaluation of some freshwater resources quality located in Bucharest and surrounding areas [1]. This case study was carried out mainly for the water in the confluence area of Arges and Dambovita rivers, where a water and sediment sampling campaign was organized in June 2018. 21 quality parameters were determined for water samples and for the sediment samples the heavy metals content was evaluated. The results of the water samples analysis allowed the framing in quality classes, and for sediment samples the values obtained were compared with the chemical quality standards for sediments, according to the current national regulations. Following the assessment, it was established that the freshwaters in both Arge� River and Dambovita River, downstream the confluence with the Dambovita River are loaded with different pollutants, such as organic substances and nutrients leading to a lower water quality classification.

Water Quality Classification

Considering that the limits with determined water quality classification using maximum degree criteria in traditional fuzzy comprehensive evaluation method, a improved fuzzy comprehensive evaluation method for water quality assessment is established based on confidence criteria. The method can effectively avoid the problems that include the water quality unclear classification and the unreasonable result, etc. Finally, the water quality of Chaping River is taken as a case study and the assessment results show that the sections in Chaping River water area can be described into 3 “category Ⅰ”, 5 “category Ⅱ” and 2 “category Ⅲ” states in 2008.
