Influence of alkalinity, hardness and dissolved solids on drinking water taste: A case study of consumer satisfaction

Two surveys of consumer satisfaction with drinking water conducted by Taiwan Water Supply Corp. are presented in this study. The study results show that although a lot of money was invested to modify traditional treatment processes, over 60% of local residents still avoided drinking tap water. Over half of the respondents felt that sample TT (from the traditional treatment process) was not a good drinking water, whether in the first or second survey, whereas almost 60% of respondents felt that samples PA, PB, CCL and CT (from advanced treatment processes) were good to drink. For all drinking water samples, respondent satisfaction with a sample primarily depended on it having no unpleasant flavors. Taiwan Environmental Protection Administration plans to revise the drinking water quality standards for TH and TDS in the near future. The new standards require a lower TH concentration (from currently 400mg/L (as CaCO(3)) to 150mg/L (as CaCO(3))), and a lower TDS maximum admissible concentration from the current guideline of 600 to 250mg/L. Therefore, this study also evaluated the impacts on drinking water tastes caused by variations in TH and TDS concentrations, and assessed the need to issue more strict drinking water quality standards for TH and TDS. The research results showed that most respondents could not tell the difference in water taste among water samples with different TDS, TH and alkalinity. Furthermore, hardness was found to be inversely associated with cardiovascular diseases and cancers, and complying with more strict standards would lead most water facilities to invest billions of dollars to upgrade their treatment processes. Consequently, in terms of drinking water tastes alone, this study suggested that Taiwan Environmental Protection Administration should conduct more thorough reviews of the scientific literature that provides the rationale for setting standards and reconsider if it is necessary to revise drinking water quality standards for TH and TDS.     

基于MODFLOW数值模拟法的地下水饮用水源保护区划分

我国城乡居民饮用水安全现状不容乐观,饮用水源污染已经成为较突出的社会问题,其中地下水饮用水源污染更为突出.饮用水源保护区划分是保证水质安全的重要措施,饮用水源保护区划分方法较多,其中数值模拟法能客观并详细地描述含水层结构与水文地质条件,适用于各种背景的地下水水源研究.本文以崇州市城区饮用水源为例,采用MODFLOW软件建立地下水渗流场,应用MODPATH对水源地抽水井进行粒子逆向示踪模拟,根据不同的时间标准确定一、二级保护区范围,并结合区域水文地质条件和地标、地界特点确定各级保护区的界线.     

我国会计准则与国际会计准则无形资产会计处理的比较与分析

在知识经济不断发展的今天,企业无形资产的比例与重要性日益提高,我国现行会计准则中有关无形资产的许多规定与国际会计准则的规定存在明显差异,这便造成无形资产在总体规模、发展水平、经营效率等方面与发达国家有很大差异,而会计信息使用者越来越关注无形资产的状况,以便做出合理的决策。在这种背景下探讨我国无形资产会计准则与国际会计准则的差异具有重要意义。     

秦皇岛市农村饮水安全状况调查与管理对策

秦皇岛市农村饮水安全状况调查结果显示,90％受访户采用家庭分散式浅井取水、100％的用户取水后以漂白粉消毒,但消毒剂的投加不规范。当地政府从未组织对水质进行安全检测,农村缺少污水处理和垃圾处理设施,缺少健全的供水管理制度并且饮水安全意识薄弱。可以从加大水利资金投入推进集约化供水、引进权责明晰的多元化管理制度、建立水源地保护和水质监测的长效机制、推进农村污染综合整治等方面解决农村饮水安全问题。加强饮水安全后续管理,推进社会主义新农村建设。     

A review of the protection of sources of drinking water in China

Water is a natural resource key to human and environmental health. China has suffered serious contamination of its water sources in the past decade, which has had severe consequences on the water supplies of millions of residents. Frequent polluting accidents and the amount of wastewater discharged have caused concern for the safety of drinking water. Fortunately, those at various levels of government have realized the importance of protecting the sources of drinking water and confirmed a list of 175 nationally important sources. Measures have also been adopted to control water pollution, including infrastructural, physical, chemical, ecological, administrative, and legal measures. While helpful, some areas in need of more attention are rural water, groundwater, agricultural pollution, and domestic sewage. Based on the lessons learned from experiences in developed countries, we offer some suggestions for improving, inter alia, funding, legal construction, management, and awareness‐raising, as well as present proposals for the future protection of our sources of drinking water. Future work should focus on water quality standards, quantitative research, high technology and legislation.

A comparison in water quality: The UK and the CIS

Summary A comparison is made of major issues relating to drinking water and river water quality in the UK and the CIS (USSR). Historical and legislative aspects are briefly reviewed. In both countries there is an imbalance between the location of fresh water sources and the distribution of the population. In each country standards are used to define water quality. These standards tend to be more exacting in the CIS. In the UK derogations are used to produce a more relaxed standard. Failure to comply with drinking water standards is common in the CIS (on average 20 percent of samples). In the UK, data are recorded on a different basis, but it appears that deviations from nitrate and pesticide standards are common. In both countries' water supplies, pollution appears to be extensive with few overall signs of significant improvement. This is attributable partly to lack of effective enforcement and weak penalties for transgressors. There is a high level of public concern regarding water quality and health in both the CIS and the UK. As a consequence there are increasing signs in each country of a national determination to implement the legislation more effectively. Needs for further actions are identified.Dr Olga Bridges was born and educated in Russia. Since coming to the UK she has held posts on Soviet Studies in various universities. Dr Bridges' early research was in attitudes to languages and nationality, but more recently it has centred on attitudes to environmental issues. To further her knowledge of scientific aspects of environmental problems, Dr Bridges is currently taking the Advanced Diploma in Environmental Practice at Farnborough College of Technology, UK.

ARE RURAL RESIDENTS WILLING TO PAY ENOUGH TO IMPROVE DRINKING WATER QUALITY?1

ABSTRACT: The concentrations of iron and sulfate in community water supplies are a concern for a number of areas in southwestern Minnesota. This study used the contingent valuation method to determine how much consumers would be willing to pay to improve their drinking water quality. On average, individuals were willing to pay US$5.25 per month (in 1995 U.S. dollars) to reduce the level of iron and US$4.33 per month to reduce the level of sulfate in their water to the USEPA's secondary standards for drinking water quality. Respondents with negative perceptions of their drinking water quality were willing to pay more to improve water quality. The aggregate annual willingness to pay (WTP) for all consumers in community water systems in southwestern Minnesota that were out of compliance with water quality standards were estimated to be US$2.4 million and US$2.0 million (in 1995 dollars) for reducing the levels of iron and sulfate, respectively. Yet the total WTP of consumers who use small community water systems may not be enough to pay the full cost of providing improved water in those systems. Economies of scale in water treatment and difficulties in financing improvements mean that technical innovation, government assistance, or institutional changes may be needed to improve water quality in these areas.
