  • Brackish Water as a Resource

    There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although ...

  • December BioCycle World

    Economic Impact Of Recycling In Texas The Texas Commission on Environmental Quality (TCEQ) released its recent study on the economic impact of recycling activities in the state. Approximately 9.2 million tons of MSW designated materials were recycled in Texas in 2015. Typical recyclables (paper, plastics, metal, and glass), organics (yard trimmings, brush, green waste, and food and ...

  • Train derailment prompts contaminated land investigation

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • 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 ...

  • Fluoride levels in drinking water and other surface water of an industrial area belt of Orissa State in India

    The fluorosis problem along with endemicity characterised by high degree of industries releasing fluorides into the environment was studied to quantify the fluoride levels in the different water sources. The analysis showed that out of 17 tube wells monitored, three (17.65%) showed higher fluoride levels. Among the open well monitored, 17 (58.54%) had higher fluoride content out of 41. The ...

  • 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 ...

  • The response of mangrove soil surface elevation to sea level rise

    Coastal ecosystems such as mangroves can reduce risk to people and infrastructure from wave damage and flooding. The continued provision of these coastal defence services by mangroves is dependent on their capacity to adapt to projected rates of sea level rise. This report explores the capacity of mangrove soil surfaces to increase in elevation in response to local rises in sea level. Historical ...

  • Removal of DOC and its fractions from surface waters of the Canadian Prairie containing high levels of DOC and hardness

    In this paper removal of dissolved organic carbon (DOC) and its fractions by chemical coagulation was studied. Raw water was collected from the Red River (Manitoba, Canada). This source water has a DOC concentration ranging from 8 to 12 mg L−1 and total hardness of about 400 mg L−1 CaCO3, which represents a typical surface water quality of the Canadian Prairie. ...

  • 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 ...

  • Surface/bathing water monitoring (Denmark) - Case Study

    In order to find the possible fecal sources to the sporadic high concentrations of bacteria, the municipality of Hjørring (DK) has set up a BACTcontrol in the ditch to monitor the E.coli levels. For this purpose the BACTcontrol is built into a movable trailer and powered by solar panels. This allows the BACTcontrol to run continuously (6 samples per day) for 7-14 days depending on the ...

  • Hydraulic “Fracking”: Are surface water impacts an ecological concern?

    Use of high‐volume hydraulic fracturing (HVHF) in unconventional reservoirs to recover previously inaccessible oil and natural gas is rapidly expanding in North America and elsewhere. Although hydraulic fracturing has been practiced for decades, the advent of more technologically advanced horizontal drilling coupled with improved slickwater chemical formulations has allowed extensive natural ...

  • Common Treatment Technologies for Halogenated VOCs in Ground Water, Surface Water and Leachate

    It may be necessary to know other subsurface information to provide remediation of VOCs in the ground water. Treatability studies to characterize the biodegradability may be needed for any biodegradation technologies. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would ...
