  • Biological active groundwater filters: exploiting natural diversity

    In the Netherlands, biological trickling filters without chemical pre-oxidation are generally applied to treat anaerobic groundwater, containing methane, iron, ammonium and manganese. Previous research showed that all compounds can be removed in one filter step and that not only the ammonia oxidation (by nitrification), but also the iron oxidation is often a biological process, despite oxygen ...

  • Effectiveness of oxidative filter materials for manganese removal from groundwater

    The experiments reported in this paper were conducted at a pilot plant consisting of filtration columns filled with oxidative filter materials. The installation was supplied with water containing manganese in concentrations ranging from 0.2 to 1.4 mg/L. The aim of the experiments was to determine the effectiveness of manganese removal on the three filter media as a function of their internal ...

  • In Search of Ideal Groundwater Treatment

    As surface water supplies become increasingly polluted and difficult to treat, the use of groundwater continues to increase. Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption. Worldwide, groundwater makes up 95% of available freshwater, and nearly half of the U.S. population receives all or part of its drinking water from ...

  • Serological responses to Cryptosporidium antigens among women using riverbank-filtered water, conventionally filtered surface water and groundwater in Hungary

    ABSTRACTWe compared serological responses to Cryptosporidium parvum antigens using surplus sera from females undergoing routine screening for pregnancy from three counties in Hungary where bank-filtered surface water, conventionally filtered and disinfected surface water, and groundwater from either a karst or confined aquifer are commonly used for drinking water. The primary purpose was to ...

  • Pacific place contaminated groundwater treatment facility

    Location: Vancouver, B.C. Owner: B.C. Ministry of Environment, Lands and Parks Description: This $1.5 million facility is capable of treating 135 L/min of contaminated groundwater, removing primarily BTEX and PAH. Through aeration, pH adjustment, and polymer addition, flocculation and settling, the majority of the contaminants are removed. ...

  • More efficient alkalisation with ground limestone in groundwater treatment

    Most Finnish groundwater must be alkalised before use as municipal drinking water because it is corrosive. The corrosiveness is due to low pH and softness of water. Groundwater also often contains aggressive carbon dioxide (CO2), so there is more free CO2 than is required to keep calcium and hydrogen carbonate in solution. The most popular alkalisation method in the past was addition of ...

  • Groundwater pump & treat and SIPEX skimmimg system

    GRS has supplied and installed a system for the abstraction of free-phase floating creosote contamination. The system comprises frequency controlled submersible pumps for precise hydraulic control and our motorised interface tracking system which, due to large local water table fluctuations, was modified to provide a product/water interface tracking range of 5m.Abstracted groundwater is pumped to ...


  • The effectiveness of arsenic remediation from groundwater in a private home

    Abstract Private wells are the source of drinking water for approximately 15% of households in the United States, but these wells are not regulated or monitored by government agencies. The well waters can contain arsenic, a known carcinogen that occurs in groundwater throughout the nation at concentrations that can exceed the Maximum Contaminant Level defined by the U.S. Environmental ...

  • Mathematical model predicting arsenic bioleaching in groundwater treatment

    In the Southeast Asia region, arsenic contamination of groundwater has been reported in several countries and a large number of arsenic treatment units were installed in many regions. Microbial activity can greatly affect the mobilization of arsenic under anaerobic conditions when coupled with the oxidation of organic matter. In this study, a mathematical model was developed to predict the ...

  • Monitoring groundwater resources for Municipalities - Case Study

    Background The City of Tucson is located in the Sonoran Desert in southwest United States (U.S.), approximately 100 km north of the Mexico-U.S. border. Tucson Water operates more than 215 groundwater wells, covering more than 300 square miles, providing more than 37 billion gallons (140 million m3) of potable water to its 730,000 inhabitants each year. The region receives only 12 inches of ...

  • A new no-purge, non-displacement groundwater sampler

    What Is It? The HydraSleeve sampler is designed to collect representative water samples from monitoring wells without purging. The disposable sampler collects a discreet sample from only the 'fresh formation' water in the screened interval of the well. It is fast, inexpensive, simple to use, generates no purge water and collects a sample suitable for all analytical parameters. Why It Works The ...

  • Occurrence of norovirus and other enteric viruses in untreated groundwaters of Korea

    A total of 39 water samples from 23 different groundwater wells in Korea were collected and analyzed in order to monitor the occurrence of norovirus (NoV) and other indicator microbes as the first part of a national survey of groundwater. More than 500 L of untreated groundwater were filtered through 1MDS filters. Following elution and concentration by organic flocculation, PCR and sequence ...
