  • Train derailment prompts contaminated land investigation

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • Error analysis for river water quality prediction using back propagation modelling

    The purpose of this research is to describe the errors of Back Propagation (BP) technique that could be applied in river water quality prediction. ANN was trained by using the upriver data to forecast the downriver quality in two approaches of long-distance forecasting and short-distance forecasting respectively. It showed that the predicted results from short-distance approach were more accurate ...

  • Assessment of the quality, effectiveness, and acceptability of ceramic water filters in Tanzania

    Globally, approximately two billion people drink contaminated water. Use of household water treatment (HWT) methods, such as locally manufactured ceramic filters, reduces the diarrheal disease burden associated with unclean water. We evaluated the quality, effectiveness, and acceptability of ceramic filters in two communities in Arusha, Tanzania, by conducting: 1) baseline household surveys ...

  • Prediction of the quality of public water supply using artificial neural networks

    The Health Surveillance Program was established by the Regional Health Authority of Alentejo to control the quality of public water supply. This authority divides the water quality parameters into three distinct groups, namely P1 (pH and conductivity), P2 (nitrate and manganese) and P3 (sodium and potassium), for which the sampling frequency is dissimilar. Thus, the ...

  • Full scale evaluation of diffuser ageing with clean water oxygen transfer tests

    Aeration is a crucial part of the biological wastewater treatment in activated sludge systems and the main energy user of WWTPs. Approximately 50 to 60% of the total energy consumption of a WWTP can be attributed to the aeration system. The performance of the aeration system, and in the case of fine bubble diffused aeration the diffuser performance, has a significant impact on the overall plant ...

  • Comparison of two multivariate classification models for contamination event detection in water quality time series

    This paper explores two applied classification models alerting for contamination events in water distribution systems. The models perform multivariate analysis of water quality online measurements for event detection. The developed models comprise an outlier detection algorithm and a following sequence analysis for the classification of events. The first model is an unsupervised minimum volume ...

  • Confronting allegations of air quality non-compliance

    A facility with an air quality permit must comply with all the conditions of that permit and demonstrate its compliance on an on-going basis. Unfortunately, no matter how diligently the facility and corporate staff strives to assure continuous compliance, unexpected compliance challenges can occur. For example, new equipment fails the emissions guarantees provided by equipment vendors; new staff ...
