The most effective means of consistently ensuring the safety of a drinking water supply is through the use of a comprehensive risk assessment approach that encompasses all steps in water supply from catchment to consumer. The approach of this book is to promote an understanding of the entire water supply system, including the hazards that can compromise drinking water quality, safety and develops effective measures to assess and manage risks arising from those hazards using spatial model. Comparative evaluation of certain physical, chemical and biological characteristics of raw, treated and potable water at distribution network has been ongoing. Applying a GIS model will provide visual impacts for various hazards using WQI, which has formed a series of prediction maps for risk assessment. The objective of this book is to help researchers, professionals, and end-users working in water supply systems with the identification of relevant hazards by providing a catalogue with potential hazards of technical, environmental or human origin for the entire system.

Different models of Water Quality Indices (WQIs) and Water Pollution Indices (WPIs) were considered as effective tools to assess the water quality and suitability for different purposes. Water and sediments samples were collected monthly from Dec., 2012 to Nov., 2013. Thirty-one water variables were measured to assess the water quality and degree of pollution. Some heavy metals in water and sediments, also TPHs, n-alkanes and PAHs were detected. According to GWQI, DWQI and IWQI ranges, the water can be classified as poor - marginal for general and irrigation use. According to NSF-WQI range the water classified as poor-unsuitable for drinking use. The water can be considered as medium - excellent for aquaculture use according to MOC-WQI range. TSI range referred to mesotrophy- eutrophy water, whereas water can be classified as very high trophic level according to TRIX range. OPI range referred to weak organic -non organic pollution status. HPI range referred to polluted water according to impermissible values of dissolved Pb, Fe and Cd. Source of n-alkanes was mainly biogenic and pyrogenic and at least petrogenic, while the source of PAHs compounds pyrogenic and petrogenic.

The approach of this book is to promote an understanding of surface water quality, including the hazards that can compromise water quality and develops effective measures to assess and manage risks arising from those hazards using spatial and statistical models. Evaluation of 42 drinking water quality parameters has been done on a monthly basis during 6 years. Applying a GIS tool will provide visual impacts for various hazards using WQI, which has formed a series of prediction maps for risk assessment. The results showed that surface water is remarkably influenced by wastewater discharge, especially at drought period. Prediction model proved a practical and economical value that gives an easier and effective solution through selecting the best decisions to enhance water quality, assurance of public health protection can be gained and be providing a comprehensive preventive strategy for drinking water system management can be achieved. The book is written for post-graduates, researchers and professionals involved in water quality monitoring and assessment of surface waters and want to improve the scope and reliability of their systems with using water dynamic prediction models.
