Drinking Water Standards and Their Implementation—A Critical Assessment

Drinking water standards in South American countries: convergences and divergences.

In this paper we present a comparative assessment of drinking-water standards from almost all South American countries, using the USA and the Canadian standards and the World Health Organization (WHO) Guidelines as references. Similarities and discrepancies between standards/guidelines were identified through descriptive analyses and, in the case of chemical standards, clustering techniques. In...

Safe drinking water standards for First Nations communities.

Introduction to Drinking Water Risk Assessment

The need for a clean and safe drinking water supply for centers of population has been recognized for over 2000 years. The early Romans recognized that human activities and effluent were a major source of water pollution, and that providing water from relatively unpopulated areas was a solution to the problem. In 312 b.c. the Romans under Appius Claudius began development of an aqueduct system ...

Lifetime risk assessment of Radium-226 in drinking water samples

Background: One of the most significant radionuclides in natural drinking waters is 226Ra and its decay products. It is potential of health problems, including cancer risk. In this study, the effect of 226Ra concentration in 28 drinking water samples collected from the North Guilan province was investigated. Materials and Methods: The activity concentrations of 226Ra were measured by using of r...

Assessment of Drinking Water Quality from Bottled Water Coolers

BACKGROUND Drinking water quality can be deteriorated by microbial and toxic chemicals during transport, storage and handling before using by the consumer. This study was conducted to evaluate the microbial and physicochemical quality of drinking water from bottled water coolers. METHODS A total of 64 water samples, over a 5-month period in 2012-2013, were collected from free standing bottled...
