  • Remote Sensing Techniques to detect Surface Water Quality Constituents in Coastal and Inland Water Bodies from Point or Non Point Pollution Sources

    This study demonstrates that point and non-point pollution sources in coastal and inland water bodies can be identified and monitored using remote sensing techniques so early corrective action can be take to prevent or minimize Harmful Algae Blooms (HAB’s). By tracking these changes in the remote sensing images could be very beneficial in establishing cleanup and restoration efforts for improving ...

  • Technological approaches to providing safe drinking water for rural and remote areas

    Provision of safe drinking water is one of the key drivers in our technological pursuits. A number of habitations are suffering from a variety of water quality problems such as excess salinity, iron, arsenic, fluoride, nitrate and microbial contamination. Simplicity of operation, less dependence on external sources of power supply, minimisation of wastewater, etc., are some of the ground rules to ...

  • Chignik Lake, Alaska: Remote Community Water Treatment Plant Pilot Testing

    Chignik Lake, Alaska is a small community located on the south side of the Alaska Peninsula. The community’s only potable water source is one groundwater well, which is located within close proximity to potential contamination sources. Due to this threat of contamination and per the recommendations contained in the sanitation facilities master plan completed on behalf of the community in 2000, ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • Map Algal Blooms with Satellite Remote Sensing Technology

    The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae. Algal blooms can result in ecological, ...

  • Remote monitors track river restoration success

    The Norfolk Rivers Trust has installed a remote river monitoring station that has been tracking water quality and flow before and after river restoration work at an area of ecological importance on the River Nar. Rising in chalk hills to the east of the village of Tittleshall, the river flows south for 2.5 km until it reaches Mileham, then predominately west for 39.5 km through the villages of ...


  • Water Quality Monitoring and Testing Using an Environmental Logger

    Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

  • Energy and clean water coproduction in remote islands to face the intermittent character of wind energy

    In many small- or medium-sized remote islands, there is a significant electrical power shortage, where the water resources are quite limited. This unfavourable situation results in the operation of high cost autonomous thermal power stations and the transportation of fresh water of questionable quality at extremely high prices. Wind energy can definitely contribute on solving these problems at a ...

  • A new approach to solar desalination for small- and medium-size use in remote areas

    A conventional solar still produces 6 litres of fresh water per square metre per day of collector surface. With heat recovery and air mass circulation we can reach up to 20 litres m3/d. The quality of the processed water is always very high so that the investment costs are justified. This depends on the material used and the price of the solar stills. The advantage of the solar still is ...
