Biological Instability in a Chlorinated Drinking Water Distribution Network
The purpose of a drinking water distribution system is to deliver drinking water to the consumer, preferably with the same quality as when it left the treatment plant. In this context, the maintenance of good microbiological quality is often referred to as biological stability, and the addition of sufficient chlorine residuals is regarded as one way to achieve this. The full-scale drinking wate...
متن کاملTrihalomethane formation potential in drinking water from Minab Steghlal dam to water distribution network in Bandar Abbas, Iran
Introduction: Organic matters enter to drinking water from a variety of sources, but one of the major sources of these compounds in aqueous solution can be decomposed plant and microbial residues. Chlorination is the most common method for water disinfection, the free chlorine in the water reacts with natural organic compounds and form disinfection byproducts. One of the dangerous byproducts is...
متن کاملEpidemiological evidence of carcinogenicity of chlorinated organics in drinking water.
Concern has recently been voiced over possible chronic toxicity associated with chlorination of public drinking water supplies in the United States. This paper reviews the available evidence and the studies underway to further evaluate hypothesized associations between cancer risk and byproducts of chlorination. Preliminary data from measures of halogenated volatiles and personal exposure histo...
متن کاملIngestion Exposure to Nitrosamines in Chlorinated Drinking Water
OBJECTIVES N-Nitrosodimethylamine (NDMA) is classified as a probable human carcinogen by the United States Environmental Protection Agency (US EPA) and is formed during the chlorination of municipal drinking water. In this study, selected nitrosamines were measured in chlorinated drinking water collected from Chuncheon, Kangwon-do, Republic of Korea, and a risk assessment for NDMA was conducted...
متن کاملMultivariate distributions of disinfection by-products in chlorinated drinking water.
Drinking water disinfection by-product (DBP) occurrence research is important in supporting risk assessment and regulatory performance assessment. Recent DBP occurrence surveys have expanded their scope to include non-regulated priority DBPs as well as regulated DBPs. This study applies a Box-Cox transformed multivariate normal model and data augmentation methods for left-censored and missing o...
