The latest trends in tourism indicate the emergence of a new segment of visitors looking for accommodation in private residences. The increase in second-home residents has led to efforts to improve knowledge of the preferences of this new type of tourist in those destinations where their presence is considerable. As one of the key variables affecting the choice of residential tourists is the environmental quality of the area, this paper focuses on testing for the existence of an inverse correlation between the loss of coastal water transparency, viewed as a measure of environmental quality, and beach aesthetics in Santa Ponça Bay, a Mallorcan coastal area containing two urban beach zones of intensive recreational use, where the proportion of second-home residents is high. The results show that the willingness to pay for improvements in water transparency diminishes in a non-linear way when transparency deteriorates, resulting in no statistically significant differences between first- and second-home residents.

New Type

As the lake water of Yuyuantan Park of Beijing has became micro-polluted water after the cycles of social landscape and the micro-polluted water run into the Kunyu River, the research adopts a method of manual simulation to treatment the micro-polluted water with a new-type of compound pattern we call landscape-designed ecological barrier which consists of ecological pond and constructed wetland . In order to weak the adverse effects of micro-polluted water on natural water, this new-type of compound pattern forms a landscape-designed ecological barrier. After 5 months experiment, results show that the landscape-designed ecological barrier has a better removal of pollutants. The removal rates of COD, TN and TP respectively reached 65.2% ~ 73.6%, 62.5% ~ 66.0% and 70.0% ~ 80.0%. And the effluent quality can reach III - IV water-quality of environmental quality standards for surface water(GB3838-2002). In Autumn, the concentration of CODCr, TN and TP in effluent sustain at IV water-quality of environmental quality standards for surface water(GB3838-2002), and at the same time create artificial landscape water with environmental aesthetic and ornamental value, bring the benefit of water resources as well as positive ecological environment effects into full play synthetically.

Effluents from the treatment plant of Saint Jean de Monts and Saint Hilaire de Riez have been injected into a confined ground water for twelve years. This ground water is connected with the sea. Effluent floats on the surface of the aquifer and it disperses by dilution at the freshwater/salt water interface. The aquifer acts as a direct overflow pipe. The injection of effluent has preserved the quality of waters in the coastal area and in the Breton Marsh.

Environment Protection

Esso’s Long Island Point facility has been operating for more than 40 years beside Western Port in Victoria, and has discharged treated wastewater and storm water to the bay for most of these years. The 2001 State Environment Protection Policy Schedule F8 for Waters of Western Port is part of Victoria’s Environment Protection Authority’s (EPA) legal framework for licensing discharges to the waters of Victoria, and requires that discharges ‘cause no detrimental change in the environmental quality of the receiving waters, as determined by an environmental monitoring program’. As part of Esso’s ongoing commitment to continuous improvement, a major upgrade to the water treatment facility was completed to further improve the quality of waters discharged to Western Port. In conjunction with this upgrade, Esso is undertaking a study on the effects of the discharge on the environmental quality of Western Port. This peer-reviewed paper presents an example of the practical application of managing discharges to ensure that the stated environmental values of a receiving environment are protected. The environmental study focuses on four key aspects of marine-environment quality relevant to key Western Port ecosystem values in the vicinity of the facility’s effluent discharge, which are: ambient water quality; seagrass biomass; jetty pile epibiota; and, ecological risk through toxicity testing. The study demonstrates the implications of basing regulatory requirements on the quality of the site-specific environmental characteristics, rather than merely effluent quality and generalised water quality objectives. Furthermore, it validates the need for sound science to underpin regulatory limits and industry practices when operating in sensitive environments.

This paper provides evidence of the effects of urban wastewater discharges on the trophic state and environmental quality of a coastal water body in a semiarid subtropical region in the Gulf of California. The concentrations of dissolved inorganic nutrients and organic matter from urban wastewater primary treatment were estimated. La Salada Cove was the receiving water body and parameters measured during an annual cycle were temperature, salinity, dissolved oxygen, nitrite, nitrate, ammonia, orthophosphate, and chlorophylla. The effects of sewage inputs were determined by using Trophic State Index (TRIX) and the Arid Zone Coastal Water Quality Index (AZCI). It was observed that urban wastewater of the city of Guaymas provided 1,237 ton Nyr−1and 811 ton Pyr−1and TRIX indicated that the receiving water body showed symptoms of eutrophication from an oligotrophic state to a mesotrophic state; AZCI also indicated that the environmental quality of the water body was poor. The effects of urban wastewater supply with insufficient treatment resulted in symptoms of eutrophication and loss of ecological functions and services of the coastal ecosystem in La Salada Cove.

Water Quality Deterioration

ABSTRACT Artificial lakes play an important role in water availability in tropical semi-arid Northeastern Brazil. However, in addition to the negative effects that dams have on the water quality of rivers, other practices such as discharge of untreated wastewater, intensive crop fertilization and fish farming have been contributing to water quality deterioration. Climate change may be another driver of water quality decrease. Increases in precipitation and drought intensities as well as temperature increase may redefine the dynamics of planktonic communities and favour species more adapted to the new environment. Water samples were collected in two reservoirs selected based on the recurrence of positive results for saxitoxins, Acarape do Meio (AM) and Sitios Novos (SN). In general, diversity in SN (1.08) was higher than in the AM (0.60). Phytoplankton dynamics in these reservoirs differ from other reservoirs in the same region of Brazil, in the sense that filamentous cyanobacteria are dominant. Furthermore, lower diversity, concentration and richness of chlorophyceae and bacillariophyceae were found in both reservoirs. Increase in diversity was observed during the intense rainy season of 2011, suggesting a slight improvement of water quality. A close inverse correlation between Cylindrospermopsis sp and other cyanobacteria was found in SN (R2= –0.862) and in AM (R2= –0.997) and the data collected demonstrates that a season with intensive rainfall may lead to lower cyanobacteria concentrations probably due to water dilution and higher flushing rates.
