  • Effective Techniques for Arsenic Removal from Water

    Arsenic is a tricky substance because it is colorless and odorless, making detecting its presence and ensuring its removal at a contaminant site tricky. However, high levels of arsenic can have drastic, fatal effects on wildlife as well as humans if left untreated. If it isn’t properly and fully extracted, serious problems can result. If you’re considering the best industrial ...

  • What You Should Know about Arsenic Treatments

    The nutrients that you put into your body directly impact your health. If you consume water with harmful substances, bacteria, or metalloids, it could create serious issues. While not a metal, arsenic is considered a metalloid because it contains many of the same properties as metallic elements. Typically found in soil, arsenic is harmful when ingested. Unfortunately, many Americans unknowingly ...

  • Groundwater level response to hydrogeological factors in a semi-arid basin of Beijing, China

    In this study, the mode of groundwater level fluctuations is analyzed by statistical approaches for 51 monitoring wells located in a semi-arid basin in Beijing from 1998 to 2013. Firstly, a geostatistical method was performed to characterize the spatial and temporal behaviors of data sets and analyze the responding mechanism of groundwater level to hydrologic features using the Geostatistics ...

  • The best way to restore environments in the face of climate change

    Florida’s Kissimmee River once flowed freely. Fish, birds and other wildlife dwelled in the wetlands it fed. But in the 1960s, spurred by public outrage over flooding, the U.S. Army Corps of Engineers straightened the winding waterway and turned it into a drainage canal. Flip forward a few decades and the river is returning — at least in part. The U.S. Army Corps of Engineers has ...

  • Concrete Construction Health Effects

    It’s no secret that working in Concrete Construction is dangerous. The immediate safety hazards are well known. Getting speared or cut on rebar, sore from the hard physical labor; cuts or punctures from nails; and struck by tools, materials or equipment can all cause injuries. Add to that possible falls especially at the leading edge; cuts or shock from powered equipment; burns or explosion ...

  • Efficient removal of some anionic dyes from aqueous solution using a polymer-coated magnetic nano-adsorbent

    For the efficient removal of some anionic dyes, a novel adsorbent was developed. The adsorbent was prepared by coating a synthetic polymer on magnetite nanosphere surface as a magnetic carrier. The synthesized nano-adsorbent was fully characterized using Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometer, X-ray diffractometer, scanning electron microscope, and ...

  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • Is Wired Monitoring Still Relevant? Wired vs. Wireless

    Environmental monitoring is a crucial practice for ensuring the safety of critical equipment and can be used in optimizing and automating environmental control systems for efficiency.  In recent years, IT managers, facility managers, and SCADA operators are now able to monitor and detect a wide range of environmental conditions in real-time. This data provides an ...

  • Extreme rainfall statistics in the Marche region, Italy

    A statistical analysis of the rainfalls is carried out for detecting a possible trend in the observed data. The rainfall dataset refers to the historical series collected in the hydrographic basins of the Marche region. On the one hand, the annual maximum daily, hourly and sub-hourly rainfalls have been analysed, on the other hand Climate Change Indices by Expert Team on Climate Change ...

  • Enhanced Bio-Remediation of Wastewater

    Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

  • Measuring sporadic gastrointestinal illness associated with drinking water – an overview of methodologies

    There is an increasing awareness that drinking water contributes to sporadic gastrointestinal illness (GI) in high income countries of the northern hemisphere. A literature search was conducted in order to review: (1) methods used for investigating the effects of public drinking water on GI; (2) evidence of possible dose–response relationship between sporadic GI and drinking water consumption; ...

  • Systematic risk management approach of household drinking water from the source to point of use

    The water safety plan (WSP) approach is being widely adopted as a systematic approach to improving the safety of drinking water. However, to date, the approach has not been widely used for improving the safety of drinking water in those settings where people have to collect water away from their home. Most rural areas in South Africa still consume unsafe water despite WSP implementation and ...

  • This polluted lake shows why we are all stakeholders when it comes to clean water

    When environmental protection gets short shrift, the price we pay can be staggering. When I visited Onondaga Lake in 1999 as part of research I did as a student at Cornell, there was no evidence the lake was once home to vibrant waterfront resorts. Yet, in the late 1800s and early 1900s, Onondaga was considered “ ...
