  • Using FTIR spectroscopy to measure hydrocarbon pollution in water

    According to the World Health Organization (WHO) and UNICEF’s 2015 Progress on Sanitation and Drinking Water report almost 700 million people around the world don’t have access to clean drinking water [1]. Poor water quality is beginning to return to the developed world too. The strain of population growth, intensified agricultural practices and continued industrial expansion have are ...

  • How Tire Shredding Protects Wildlife

    One of the most revolutionary inventions in the history of mankind was the wheel, and the best upgrade to that invention was the rubber tire, which overcame the limitations of wooden or metal wheels and made it possible to have smooth rides at fast speeds. However, there is a significant drawback to using rubber tires: eventually, they get too worn out to be useful as tires anymore and have to ...

  • Locating Groundwater Wells for Fracking Operations in West Texas - Case Study

    In June 2014, our clients used AGI resistivity imaging tools to successfully locate a 125-gallon-per-minute groundwater well in West Texas as well as geohazards that could, if left unlocated, cause significant damage to property and increase costs. Process Our clients used the ...

  • Waste water: Skimming the surface

    A walk on the wild side gave the founder of a Calgary service company a new appreciation for clean water, indirectly laying the foundation for his own future. Years ago, while on the island of Borneo, Jason Snydmiller learned the super-major he was under contract to would promptly fine any contractor that left oil in local waters. Although it seemed harsh then, the rule was necessary, since ...


  • Surface Runoff

    Surface runoff is the water flow that occurs when soil is infiltrated to full capacity and excess water from rain, snowmelt, or other sources flows over the land. This is a major component of the hydrologic ...

  • A review on interaction of groundwater and surface water

    Interactions between groundwater and surface water play a fundamental role in water resources management. The movement of water between groundwater and surface water should be investigated in view of both quantity and quality aspects of water resources. In this paper, an attempt is made to define the primary concepts of this interaction and to illustrate a case study undertaken in ...

  • Phosphorus control protects surface waters

    Phosphorus is the decisive factor for excessive algae and plant growth in water bodies, that’s why quality standards require reductions in the amount of phosphorus released from wastewater treatment plants into rivers and lakes. In recent years, the outlet limit values have not only been reduced on national levels. Depending on the vulnerability of ecosystems, especially low target values ...

  • Containment for Ground Water, Surface Water, And Leachate

    Containment measures are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards ...

  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Trihalomethane formation in ozonated and chlorinated surface water

    Abstract The relatively recent discovery of disinfection by-products has driven the main regulatory organisms to set maximum contaminant levels for certain substances in drinking water. Trihalomethanes can be deemed as the most important group of by-products in chlorinated surface waters. The present work has focused on trihalomethane formation in a full-scale water treatment plant. We studied ...

  • UV Experience for Inactivating Cryptosporidium in Surface Water Plants

    The disinfection of pathogenic microbes in drinking water has been largely successful over the last century due to the use of chlorination. However, research conducted in the 1970's revealed that by-products formed during the chlorination process are potentially carcinogenic and that there is a direct correlation between the concentration of chlorination by-products and the probability of certain ...

  • Assessment of heavy metal pollution in surface water

    A total of 96 surface water samples collected from river Ganga in West Bengal during 2004-05 was analyzed for pH, EC, Fe, Mn, Zn, Cu, Cd, Cr, Pb and Ni. The pH was found in the alkaline range (7.21-8.32), while conductance was obtained in the range of 0.225-0.615 mmhos/cm. Fe, Mn, Zn, Ni, Cr and Pb were detected in more than 92% of the samples in the range of 0.025-5.49, 0.025-2.72, 0.012-0.370, ...

  • Rainfall and surface water resources of Rajasthan State, India

    The water resources in Rajasthan State are facing a crucial stage even after average/good rainfall. Temporal distributions as well as the spatial variability of rainfall within the state were investigated by applying an analysis of variance (ANOVA) test. The effect of change in catchment characteristics and anthropogenic activities on overland flow are also investigated in this paper by ...

  • Keoladeo National Park: highlighting surface water tensions

    Keoladeo National Park in Rajasthan, India is a world-class bird sanctuary and world heritage site experiencing serious ecological stress due to drought and upstream dam construction. In response to this reoccurring scarcity of water, Indian authorities have announced a new 17 km pipeline to divert water to the wetland. Both the dam-induced water shortage and proposed pipeline solution raise the ...

  • Feasibility assessment of surface water disinfection by ultrafiltration

    Ultrafiltration (UF) has been presented as an alternative to chemical disinfection to obtain safe drinking water, for its ability to remove microbiological contamination. Hollow-fiber UF membranes are designed as an effective barrier to microorganisms, for their high manufacturing integrity and for the ‘potting’ method adopted to seal fibers to the feeding/extraction manifold. ...

  • Photochemical fate of the vasodilator drug pentoxifylline in surface waters

    This study is the first to comprehensively investigate the photochemical fate of pentoxifylline in natural water systems. Among all attenuation processes, indirect sunlight photolysis is very likely the primary process for pentoxifylline degradation. The combination of dissolved organic matter (represented by fulvic acid), NO3− and ...

  • Application of the membrane technology to control ammonia in surface water

    Amnonium ion is effectively removed by Reverse Osmosis membranes (Brackish water, BW; Saline water, SW). The removal efficiency of ammonium ion from a solution containing ammonium ion which is not complexed is varying in the range of 5–60%. On the contrary, ammonium ion forms complexes with other ions in water and wastewater removal efficiency was as high as 99% for the synthetic solution which ...
