  • Chromium detection in water and soil...

    What is chromium? Chromium is a metal that is widely distributed in the earth’s crust (soil and rocks), air and water. Naturally occurring chromium occurs mainly in the chromium (III) form as chromite ore, which contains oxygen, chromium (III) and other metals such as iron. Chromium (VI) compounds are produced commercially from chromite ore for a wide variety of uses. ...

  • Fate of effluent organic matter during soil aquifer treatment: biodegradability, chlorine reactivity and genotoxicity

    Hydrophobic acid (HPO-A) and transphilic acid (TPI-A) fractions of dissolved organic matter (DOM) were isolated from a domestic secondary wastewater effluent that was polished via soil aquifer treatment (SAT). Fractions were isolated using XAD resin adsorption chromatography from samples obtained along the vadose zone flowpath at a full-scale basin recharge facility in Tucson, Arizona. Changes in ...

  • Potential impacts of on-site greywater reuse in landscape irrigation

    This study investigated the effects of irrigation with different types of waters on soil, plants, and public health. The test plant was ryegrass grown in 12 planters filled with sandy loam soil and irrigated with three types of waters (4 planters for each type): freshwater, raw domestic light greywater (GW), and treated domestic light GW. The sodium adsorption ratio (SAR), EC, pH and alkalinity ...

  • Expanded HPLC Method for N-Methyl Carbamates post-column analysis of pesticides in food and potable water samples

    Carbamate pesticides are widely used around the world to protect crops. In addition, they are used as biocides for industrial or other applications and in household products. Though carbamates are biodegradable compounds and bioaccumulation usually happens only to a low extend it is important to monitor produce to make sure enough time has elapsed between harvest and applying pesticides. Also, ...

  • A pilot study on suspended activated sludge process augmented with immobilized biomass for simultaneous nitrification and denitrification

    Concurrent nitrification and denitrification (CND) are natural phenomena in the soil environment that can be applied in wastewater treatment for enhanced total nitrogen removal. However, significant renovation is necessary for existing plants to equip them for nutrient removal. At a domestic wastewater treatment plant, we performed a pilot test by installing bioplates with entrapped biomass in a ...

  • Identification of Naegleria fowleri in warm ground water aquifers

    Received for publication February 16, 2009. The free-living amoeba Naegleria fowleri was identified as the etiological agent of primary amoebic meningoencephalitis that caused the deaths of two children in Peoria, Arizona, in autumn of 2002. It was suspected that the source of N. fowleri was the domestic water supply, which originates from ground water sources. In this study, ground water from ...

  • Is Radon & Radiation from Granite Countertops a Concern?

    Over the past several years there have been numerous media reports about possible health concerns regarding granite countertops emitting radiation and radon gas into people’s homes and businesses.  Granite’s durability and decorative appearance have made it a popular building material in many homes and buildings. Almost any type of rock could contain naturally occurring ...

  • Effects of environmental lead contamination on cattle in a lead/zinc mining area: Changes in cattle immune systems on exposure to lead in vivo and in vitro

    The Republic of Zambia is rich in mineral resources, such as zinc (Zn) and lead (Pb), and mining is a key industry in Zambia. A previous study of Pb pollution in Kabwe, one of the main mining areas, found that soil was contaminated with high levels of toxic metals over a substantial area. In the present study, the authors focus on toxic metal pollution in cattle, one of the most important ...

  • Linkage of Conservation Activity to Trends in the U.S. Economy

    Abstract: As an economy grows, natural capital such as timber, soil, and water is reallocated to the human economy. This conflict between economic growth and biodiversity conservation creates a conundrum for conservation biologists because traditional forms of conservation action require money. We hypothesize that conservation spending in the United States is highly ...


  • Establishment and growth of two willow species in a Riparian zone impacted by mine tailings

    Received for publication April 2, 2008. A field study was initiated to determine survival, growth characteristics, and metal uptake of two montane riparian willow species, Geyer (Salix geyeriana Andersson) and mountain (S. monticola Bebb) willow, grown in amended fluvial mine tailing deposits. Revegetation was done with staked and previously rooted cuttings to determine if planting method had an ...

  • NORMs contamination treatment using Ivey-sol technology

    NORMs (naturally occurring radioactive materials) are found almost everywhere, and many natural materials, such as the earth’s crust, contain such radioactive materials. So what happens when oil and gas activities such as petroleum refining and natural gas extraction, disturb such radioactive material? They can alter the natural background radiation — the radiation that we are naturally exposed ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
