Satellites monitor algae toxin levels to ensure drinking water safety
Imagine that your daily routine is disrupted by a sudden ‘do not drink’ advisory for your local tap water because of elevated toxin levels. This scenario became a reality for cities like Toledo, OH in 2014, affecting more than 400,000 residents. The source? Microcystins - toxins produced by cyanobacteria, commonly referred to as blue-green algae. As climate change and human ...

How the Portable Quadrupole Analyser (pQA) Can Be Used in Climate Change Studies
Climate change studies have been increasingly common and important in recent years. The impact of human activities on the environment, global warming, and sea level rises have been well documented and debated, and whilst we have gained a deeper understanding of these issues in recent years, there is still so much more to learn. In this article, we discuss how the pQA from Hiden Analytical can be ...

Project - Database and Groundwater Model Analysis of the Oak Ridges Moraine, Ontario
Project Description: Land development in the Greater Toronto Area (GTA) is encroaching on the high recharge areas of the Oak Ridges Moraine (ORM). The ORM provides drinking water for over 2 million residents and headwater streamflow for all the major rivers in the GTA. As part of provincial efforts to protect the moraine, Earthfx was hired to develop a database, regional scale groundwater flow ...

Water Crisis in Jordan
Facing severe drought and needs of refugees, the country is digging deep for freshwater resources Jordan, one of the driest countries on earth, is said to be experiencing its worst drought in 900 years. Its baseline water supply is inadequate and becoming worse with climate change. And, since the eruption of war and political unrest in the region, it has been difficult to name another country on ...

Water Flow Monitoring Helps Avoid Costly Fines
Water Distribution Company Refines Pumping System Many water distribution companies use a similar process for Water Flow Monitoring: Collect water from a well with the help of water pumps, utilize a pond or reservoir to temporarily store the water and maintain a loading center to fill water trucks for transport. The problem is how to pump the maximum allowable volume of water on a day-to-day ...

TSCA Reform: An Analysis of Key Provisions and Fundamental Shifts in the Amended TSCA
On June 22, 2016, President Obama signed into law the Frank R. Lautenberg Chemical Safety for the 21st Century Act (Lautenberg), which makes important changes to the Toxic Substances Control Act (TSCA). Lautenberg results in fundamental shifts in the requirements and approach under TSCA, while introducing important new concepts and approaches. It is our view that the body of changes, including ...

The impact of low-flow season on source drinking water quality, Rosetta branch, Egypt
The present work was conducted to document the problems raised regarding low-flow in the Rosetta branch, Egypt and to develop management options to protect drinking water sources. The water quality was monitored during low-flow periods at four drinking water intakes. Results showed an increase in electric conductivity (EC), ammonium (NH4), nitrite (NO2), phosphate (PO4), and total organic ...

Radon-222 from different sources of water and the assessment of health hazard
Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56–98.57, 0.88–25.49, 0.73–1.35 and 0.24–1.03 Bq.L−1 for borehole, well, packaged and utility water, respectively. Samples from boreholes had the highest radon concentrations with about 67% ...

Removal of aluminium and iron from surface water by conventional water treatment
Detailed source water monitoring showed large variations in the total concentrations of aluminium and iron in the Vaal Dam, South Africa, which were highlighted as a specific concern for one of the largest drinking water treatment plants in South Africa. This study aimed to better understand the presence of these metals in the source water, removal of these metals through the conventional ...

Preparation and characterization of polymeric phosphate-aluminum sulphate for source water treatment
Aluminum sulphate (AS) as a common coagulant has been widely used in water treatment. Pre-hydrolysed AS (PAS) has higher molecular weight, presenting stronger water treatment performance; however, its poor stability has greatly limited its application. Therefore, there is still a need to obtain a stable PAS. In this study, a method for stabilizing PAS product was proposed and a new coagulant, ...

12 strategies for moving from water scarcity to abundance
How did a country that’s 60 percent desert achieve water security? In about 10 years, beginning shortly after the new century, Israel went from scarcity of water and fear of drought to abundance and independence from climate conditions. This dramatic change was made possible by the 70 years that preceded it in which a cadre of often brilliant engineers, scientists and policy-makers ...
