Cung cấp một nguồn cung cấp nước an toàn là điều cần thiết cho sức khỏe con người. Có một nhu cầu cơ bản nước về chất lượng và số lượng đủ để nó không chỉ duy trì cuộc sống, còn cho phép sự phát triển kinh tế và xã hội tiếp tục. Nước đang được sử dụng trong tăng số lượng. Nó không phải chỉ để uống, mà còn sản xuất thực phẩm, rửa và làm sạch, quy trình sản xuất công nghiệp bao gồm làm mát, vận chuyển, vui chơi giải trí, chuyển hướng, và thủy lợi | 5 Legislation and Water Quality CONTENTS Monitoring Water Indicator Organisms. 54 Coliforms . 54 Escherichia coli .55 Enterococci Faecal Streptococci . 55 Sulphite Reducing Clostridia and Clostridium Heterotrophic Colony Methods Used to Detect Indicator Positive References. 58 INTRODUCTION Provision of a safe water supply is essential for human health. There is a basic need for water in sufficient quality and quantity so that it not only sustains life but also allows for continued economic and social development. Water is being used in increasing quantities. It s not just for drinking but also food production washing and cleaning industrial production processes including cooling recreation transport navigation and irrigation. As rivers lakes and seas which are used for drinking water abstraction and wastewater discharge cross national and international boundaries it is essential that there is cooperation between users of such a vital resource. Pollutants which are put into a river upstream can have health consequences for those abstracting water downstream. There is an increasing awareness of the need for international agreements for the provision of water and management of water resources. The Israelis for example supply 55 million m3 per year of water to Jordan from the Yarmouk Such agreements are also necessary for the protection of the quality of water which transcends international boundaries. To facilitate this there are various international agreements for example the ECE Convention on the Protection and Use of Transboundary Watercourses and International Lakes. In June 1999 a draft protocol on 49 2000 by CRC Press LLC 50 Microbiological Aspects of Biofilms and Drinking Water water and health was drawn up for submission to the Third Ministerial Conference on .
