Rapid Urbanization

Lake Sapanca is the drinking water source of the Sakarya province of Turkey. Intensive urbanization in the region is the main obstacle to implementing appropriate physical planning and measures to adapt to rapid change. The monitoring of the water quality parameters in the planning and management of the lakes is significant. The Artificial Neural Network (ANN), a mathematical representation of the human brain’s functioning, was employed to estimate the Lake’s Dissolved Oxygen (DO) concentration. pH, Magnesium (Mg), Temperature (Temp), Chemical Oxygen Demand (COD), Orthophosphate (o-PO4), Nitrite Nitrogen (NO2-N), and Nitrate Nitrogen (NO3-N) were used as independent parameters. The successful ANN model gives better results compared to the traditional multiple linear regression (MLR) analysis. The developed model can be used for forecast purposes to complete the missing data in the future and support the decision process for pollution reduction through sustainable environmental management. The eutrophication threat for Lake Sapanca has been revealed. The main objective is to create the scientific infrastructure that will draw attention to the rapid urbanization problem with ANN and eutrophication models’ outputs. It has been understood that the protection of the water budget of Lake Sapanca is the primary solution method in terms of ecological sustainability to eliminate the existing pollution.

Water quality is of great importance due to its impact on human health and aquatic systems. Since Islamabadand Rawalpindi get their drinking water from Simly dam, this makes it an important drinking water source. In thisstudy water quality parameters of Simly dam were determined and water quality index (WQI) using Arithmeticweighted method was calculated. Collection of water samples from different locations of dam and the filtration plantinstalled in the facility was done. Twelve physicochemical parameters of water quality including: pH, ElectricalConductivity (EC), Total Dissolved Solids (TDS), alkalinity, hardness, Biological Oxygen Demand (BOD), DissolvedOxygen (DO), Total Chloride, Calcium, Nitrates, Potassium and Sodium (Na) were measured to estimate the sentientand water quality of the Simly dam. WQI of both raw dam water and filtered dam water was determined using WorldHealth Organization (WHO) standards for drinking water. The water quality index of raw dam water was found to be62.79 while that of filtered dam water was 49.43. The WQI of the unfiltered raw dam water was found to be in class Cthat is poor category, while the filtered dam water was falling in Class B that refers to good category according to waterquality index categories. Regular monitoring of water quality is recommended to ensure safe water supply toconsumers.

Critical Success

The success of source protection in ensuring safe drinking water is centered around being able to understand the hazards present in the catchment then plan and implement control measures to manage water quality risk to levels which can be controlled through downstream barriers. The programs in place to manage source protection are complex sociotechnical systems involving policy, standards, regulators, technology, human factors and so on. This study uses System Theoretic Process Analysis (STPA) to analyze the operational hazards of a typical drinking water source protection (DWSP) program and identify control measures to ensure safe operations. To validate the results a questionnaire was developed and distributed to specialists in DWSP in Taiwan, Australia and Greece. Using Principle Components Analysis (PCA) of the questionnaire responses, the study identified four critical success factors (CSFs) for DWSP. The four factors identified are ‘Policy and Government Agency Support of Source Protection’, ‘Catchment Risk Monitoring and Information’, ‘Support of Operational Field Activities’ and ‘Response to Water Quality Threats’. The results of this study provide insight into the approach of grouping of source protection measures to identify a series of targeted CSF for operational source protection programs. Using CSF can aide catchment management agencies in ensuring that the risk level in the catchment is managed effectively and that threats to public health from drinking water are managed appropriately.

Abstract Chronic Kidney Disease of uncertain etiology (CKDu) is a fatal disease that causes death from kidney failure due to unknown risk factors and has already affected more than 400,000 people in the rural agricultural landscape (dry zone) of Sri Lanka. The major drinking source in Sri Lanka is groundwater and it is suspected that the pollution of groundwater sources due to agricultural means has a major impact on CKDu. The primary objective of this study is to determine whether rainwater can be used as an alternative safe drinking water source in Girandurukotte area, Sri Lanka, which is known to be an area endemic for CKDu. The physical, chemical, and biological analyses were performed to compare the water quality parameters of three water sources (groundwater, surface water, and rainwater) for Girandurukotte area. The most common storage tanks in polyethylene (PE) and ferrocement (FC) were compared to assess the influence of the material of rainwater tank on water quality. The results showed that there is a significant difference in rainwater in terms of water quality compared to groundwater and surface water. Rainwater in FC and PE tanks showed significant differences (p < 0.05) for some parameters however, they were still within accepted potable drinking water standards.

An investigation was carried out to assess the water qualities and extents of impurities in groundwater and surface water (Padma river water) in Rajshahi City area. Water samples from a total of 330 tube wells and five spots of the river Padma were analysed for physicochemical, biological and hydrological parameters with standard methods. Among all considered parameters of ground water, concentrations of arsenic, iron, manganese, total hardness, and total coliform and faecal coliform bacteria were found above the permissible limits for potable water. In case of the river Padma, biochemical oxygen demand, chemical oxygen demand, total coliform, faecal coliform and suspended solids exceeded permissible limits. Both ground and river water must be treated properly before distribution for drinking purpose. Finally, the Padma is recommended as the most sustainable drinking water source for Rajshahi City Corporation area. Keywords: Rajshahi City; Ground water; Surface water; Quality control. © 2010 JSR Publications.
