Recreation Benefits

Water pollution control policies generally direct sources (i.e., industry, agriculture) to reduce loadings of certain pollutants. Thus, evaluating the relative net recreation benefits of policies to improve water quality requires establishing a linkage between the sources, the resultant water quality degradation at the affected water bodies, and, ultimately, the effect on recreation behavior. This linkage is rarely present in the empirical literature which is, thus, deficient for water pollution control policy assessment purposes. In this paper, we estimate the relative recreational swimming benefits that may result from controlling point and nonpoint sources of pollution, respectively, in New Hampshire's lakes. We use a repeated discrete choice framework to model swimming behavior as a function of each lake's level of eutrophication, bacteria, and oil and grease. For each pollutant, at each affected lake, we identify which source is responsible for the pollution, and we conduct scenarios controlling each pollution source independently, and then, taken together. Seasonal benefit estimates are presented for each scenario. Coupled with information on the most cost effective means of generating the scenarios, these estimates provide a useful starting point for a quantitative assessment of the net recreation benefits of policies to improve the quality of New Hampshire lakes.

Luanhe River Basin

The analysis of river pollution and assessment of spatial and temporal variation in hydrochemistry are essential to river water pollution control in the context of rapid economic growth and growing pollution threats in China. In this study, we focused on hydrochemical characteristics of the Luanhe River Basin (China) and evaluation of 12 hydrochemical variables obtained from 32 monitoring stations during 2001–2010. In each study year, the streams were monitored in the three hydrological periods (April, August, and October) to observe differences in the impacts of agricultural activity and rainfall pattern. Multivariate statistical methods were applied to the data set, and the river water hydrochemical characteristics were assessed using the water quality identification index (WQIIM). The results showed that parameters had variable contribution to water quality status in different months except for ammonia nitrogen (NH4-N) and total nitrogen (TN), which were the most important parameters in contributing to water quality variations for all three periods. Results of WQIIM revealed that 18 sites were classified as 'meeting standard' while the other 14 sites were classified as 'not meeting standard', with most of the seriously polluted sites located in urban area, mainly due to discharge of wastewater from domestic and industrial sources. Sites with low pollution level were located primarily in smaller tributaries, whereas sites of medium and high pollution levels were in the main river channel and the larger tributaries. Our findings provide valuable information and guidance for water pollution control and water resource management in the Luanhe River Basin.

Lake Päijänne

Estimation of water quality impacts plays an important role in the planning of water pollution control. In this paper the connection of water quality aspects with the rest of the planning procedure is examined in the light of a case study area, Lake Päijänne in Finland. For this area an integrated water resource development plan was made by the Finnish water authorities. In order to diminish the adverse effects resulting from effluents of pulp and paper mills and municipalities, different pollution control alternatives were drawn up. Next, forecasts about the development of water quality in different alternatives were made. The most important parameters from the point of view of the different modes of water utilization were taken into account. These parameters were oxygen, phosphorus, COD, lignin and colour. In addition, in assessing the impacts, toxity of effluents was taken into consideration. The impacts of these parameters on the usability and utilization of water areas were analyzed. The forecasts of impacts on vacation settlement, water supply and fisheries were made. In the comparison of the alternatives, numerous intangible factors were involved. In the assessment of the alternatives the costs of water pollution control measures, the benefits and the adverse effects were taken into consideration. The impacts of intangible factors were assessed in each alternative by comparing the water use possibilities with the goals that had been set.

Through to analysis the influence of the effluent from the sewage treatment plant to the river water quality of Fangshen-Habaqi stream segment in lower reaches comprehensively, in order to achieve water pollution control and water function zone protection. This paper use QUAL2K model to simulate the influence to lower reaches water quality, and the simulation factor is BOD. The result showed that the downstream BOD concentration cannot reach the water quality standards Ⅲ. This paper provides some corresponding control measures, so as to provide the scientific basis of the water pollution control planning research.
