Evaluating the extent of pharmaceuticals in surface waters of the United States using a national‐scale rivers and streams assessment survey
To assess the potential exposure of aquatic ecosystems to active pharmaceutical ingredients, the authors conducted a national‐scale, probability‐based statistical survey of the occurrence of these compounds in surface waters of the United States. The survey included 182 sampling sites and targeted rivers with close proximity to urban areas. The 46 analytes reported represent many classes of ...

ESM30 conducts autonomous water sampling and monitoring - Case Study
Background Wuhan is the capital city of Hubei province in central China which has 166 lakes that cover 2,217 square km approximately counting 25% of the city. Its water coverage is one of the world’s highest. The Wuhan Environmental Protection Bureau is responsible for monitoring the surface water quality by surveying a subset of 50 lakes of their temperature, conductivity, pH, ...

Environmental Effects of Acid Rain
Air Pollution Creates Acid Rain Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Acidic deposition, or acid rain as it is commonly known, occurs when emissions of sulfur dioxide (SO2) and oxides of nitrogen (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. This mixture forms a mild ...

Sewer Misconnection Survey - Birmingham UK - Case Study
Background STS was invited independently by the Environment Agency and Severn Trent water to carry out a series of monitoring operations in an area which had a history of issues arising from the misconnection of waste water into a “clean” surface water sewer system. Traditionally surveys of this type are carried out using contractors who are tasked to lift manhole covers along a ...

SMF4 case study 2
Sewer Misconnection Survey Date: March 2010 Location: Edgebaston Birmingham UK Purpose: To test the application of the SMF4 portable fluorimeter in the detection and quantification of organic pollution from faecal matter in Surface water Sewers. Background STS was invited independently by the Environment Agency and Severn Trent water to carry out a series of monitoring operations in an ...

The detection of
Yersinia enterocolitica in surface water by quantitative PCR amplification of theail andyadA genesYersinia enterocolitica has been detected in surface water, and drinking untreated water is a risk factor for infection. PCR-based methods have been used to detect Y. enterocolitica in various sample types, but quantitative studies have not been conducted in water. In this study, quantitative PCR (qPCR)-based methods targeting the Yersinia virulence genes ail and yadA were used to survey the ...

Estimation of surface water quality in a Yazoo River tributary using the duration curve and recurrence interval approach
Pollution of surface water with harmful chemicals and eutrophication of rivers and lakes with excess nutrients are serious environmental concerns. This study estimated surface water quality in a stream within the Yazoo River Basin (YRB), Mississippi, USA, using the duration curve and recurrence interval analysis techniques. Data from the US Geological Survey (USGS) surface water monitoring ...

Detection of enteric viruses in Hungarian surface waters: first steps towards environmental surveillance
Waterborne viruses infect the human population through the consumption of contaminated drinking water and by direct contact with polluted surface water during recreational activity. Although water related viral outbreaks are a major public health concern, virus detection is not a part of the water quality monitoring scheme, mainly due to the absence of routine analysis methods. In the present ...

NMR Can Measure Groundwater Directly – Even in Permafrost Environments
In permafrost landscapes, the ground remains mostly frozen throughout the year and liquid groundwater only occurs in certain locations or during anomalously warm periods. Understanding the spatial and temporal distribution of groundwater in these environments is extremely important as it can affect processes ranging from geotechnical soil stability to the release of greenhouse gases. In a ...
