  • Reducing Wasted Food In Tennessee

    About 15 percent of Tennessee households are food insecure, and almost 1.2 million tons of food are landfilled annually. The state is moving quickly to address both realities. It is increasingly apparent that food waste and food insecurity in the United States is a problem, and it has especially hit home in Tennessee. An estimated 15.1 percent of Tennessee households are food insecure, which ...

  • Water quality in healthcare

    Rivers are important freshwater resources for many countries and human beings around the world. Social well being, economics and political development have been largely related to the availability and distribution of these freshwater resources. In many parts of the world the adverse health impacts of water supply from rivers, dam construction, irrigation development and flood mitigation have led ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Derivation of water quality standards for carbamazepine, metoprolol and metformin and comparison with monitoring data

    Environmental quality standards (EQSs) for three pharmaceuticals in surface water were derived: carbamazepine (epilepsy), metoprolol (heart failure) and metformin (diabetes). During the past years, these pharmaceuticals have been detected frequently in Dutch surface waters. The proposed standards are based on ecotoxicity data from national and European authorisation dossiers and additional ...

  • Heterogeneity of water quality in Huai River, China by using bio-monitoring data

    A new approach by combining bioindicators (BiI) and biotic indices (BIs) for evaluating water quality is presented in this paper. It is then applied to the Huai River Basin (HRB), China, which is well-known globally for its heavy anthropogenic influences. Results indicate that the spatial distribution of BI-indicated water quality has roughly the same pattern as that shown by BiI, but the ...

  • A method for deriving water‐quality benchmarks using field data

    The authors describe a methodology that characterizes effects to individual genera observed in the field and estimate the concentration at which 5% of genera are adversely affected. Ionic strength, measured as specific conductance, is used to illustrate the methodology. Assuming some resilience in the population, 95% of the genera are afforded protection. The authors selected an unambiguous ...

  • Water quality measurement extreme

    Background The characteristics of the Rio Tinto in the south-west of Spain, near Sevilla, are his ruby colour and the extremely sour pH-value between 0 and 2 pH-units. The river carries a mixture between poisonous heavy metals like copper, nickel, arsenic, iron and cadmium, dissolved in high-percent sulphuric acid. It’s not proved where these unusual conditions come from. As per current ...

  • Water Quality in South Asia

    Abstract:There are significant differences in the water chemistry of the Himalayan and southern peninsular rivers. Large and small rivers also show different types of water quality. Liquid and solid waste definitely contribute to water quality in urban centres such as Delhi and even coastal regions, as near Mumbai, are affected by waste discharges. The sub-continent also suffers from problems ...

  • Assessment of data and parameter uncertainties in integrated water-quality model

    In integrated urban drainage water quality models, due to the fact that integrated approaches are basically a cascade of sub-models (simulating sewer system, wastewater treatment plant and receiving water body), uncertainty produced in one sub-model propagates to the following ones depending on the model structure, the estimation of parameters and the availability and uncertainty of measurements ...
