  • 5 ways to conserve water this winter

    Water conservation is something we harp on during the summertime, but what about during the winter? When the irrigation systems shut down, it’s easy to put conservation on the back burner while indoor water waste continues to occur. According to the U.S. Geological Survey, the average person uses 80-100 gallons per day for everything from cooking, to showering and flushing the ...

  • Tech Tip: Deploying Sea-Bird CTD in Ice

    Large numbers of Sea-Bird conductivity instruments have been used in Arctic and Antarctic programs. Special accommodation to keep temperature, conductivity, oxygen, and optical sensors at or above 0° C is advised. Often, the CTD is brought inside protective doors between casts to achieve this. Conductivity Cell When freezing is possible, we ...

  • Mapping sedimentation features in an alluvial valley

    Sediments of the Rhone river are characterized by strong heterogeneity between clay, sand and gravel units. To map these units, we employed an electromagnetic instrument (DualEM421). This instrument das the advantage that no contact to the ground is required and it can be carried on foot. With the interpreted data it was possible to map different geologic units to a depth of up to 4.5m. ...

  • Knowledge, attitudes and practices on use of Fossa Alternas and double vault urine diverting dry (DVUDD) latrines in Malawi

    Fossa Alternas and double vault urine diverting dry (DVUDD) latrines have been extensively promoted as ecological sanitation (EcoSan) latrine options in Malawi, but little is known about whether they are used properly. A qualitative study of EcoSan users was conducted in Blantyre and Chikwawa districts, Malawi. Data were collected using in-depth interviews (IDIs). Twenty-eight (28) and ...

  • Instrumentation and Operational Considerations for On-Line pH Measurement in Samples Below 10µS/cm Conductivity

    Ordinarily pH measurements are made in water with 1,000 to 10,000 µS/cm conductivity. The conductivity comes from dissolved solids which are typically salts but also acid or base. These dissolved substances are in the solution in ion form which makes such solutions conducting. With conductivities of 1,000 µS/ cm or more, an ample supply of mobile ions provides pH electrodes with a ...

  • Degradation of gestodene (GES)–17α-ethinylestradiol (EE2) mixture by electrochemical oxidation

    Evidence of the negative effects of several pharmaceutical molecules, such as hormones and steroids, on the environment can be observed throughout the world. This paper presents the results of the anodic oxidation of the mixture of gestodene steroid hormones and 17 α-ethinylestradiol present in aqueous medium. The tests were conducted in an undivided cell containing a working volume of 50 mL, ...

  • Sustainable groundwater modeling using single- and multi-objective optimization algorithms

    This study presents the first attempt to link the multi-algorithm genetically adaptive search method (AMALGAM) with a groundwater model to define pumping rates within a well distributed set of Pareto solutions. The pumping rates along with three minimization objectives, i.e. minimizing shortage affected by the failure to supply, modified shortage index and minimization of extent of drawdown ...

  • Oxocarbon Salts for Fast Rechargeable Batteries

    Oxocarbon salts (M2(CO)n) prepared through one-pot proton exchange reactions with different metal ions (M=Li, Na, K) and frameworks (n=4, 5, 6) have been rationally designed and used as electrodes in rechargeable Li, Na, and K-ion batteries. The results show that M2(CO)5/M2(CO)6 salts can insert two or four metal ions ...

  • Microbiological water quality of the Nišava River

    Microorganisms are the ideal indicators of the organic pollution of the surface waters because of their ability to promptly respond to environmental changes. Due to poor economic situation and lack of law implementation, most wastewaters in Serbia are released directly into a surface water recipient without any, or a limited, treatment. This practice has created numerous highly polluted ...
