Toward a Satellite-Based Monitoring System for Water Quality

In an article published by Pahlevan et al. on March 5th 2018, (see the link below) information is presented on the use of satellite imagery for water quality monitoring, which was introduced in the Water Quality Workshop for End Users, which was held in Maryland on the 27th September, 2018.

Free Webinar: Paradigm Shifts in Water Quality Sensor Design

Data from continuous water quality monitoring networks inform critical activities across every sector of the surface water industry today, from meeting federal and state water quality standards and ensuring safe recreational waters, to researching and managing the effects of climate change. As such, continuous water quality monitoring networks must produce results that meet the data quality objectives for a given program while operating within the constraints of limited human resources and budgets.

Until now, however, deploying and cost-effectively maintaining an autonomous monitoring network has been limited by lack of advancements in sensor technology.

Join David A. Bossie for a free online training webinar exploring how innovations in water quality sensor design are challenging old beliefs about the ability of autonomous, long-term monitoring networks to produce representative, comparable data at a price point within reach of most organizations.

Specifically, we’ll learn how you can operate pH sensors hands-free for months that previously required calibration every 1-2 weeks.  We’ll see how turbidity sensor accuracy is no longer worrisome due to improved linearity across the range of 0-4000 NTU, and how the use of LEDs and filters provide stability not found with incandescent light sources.  Finally, we’ll explore how you can deploy conductivity sensors in biofouling environments without loss of accuracy thanks to an innovative, open-faced design that allows wiping.

Learning Objectives
Attendees can expect the discussion and education of the following learning objectives:

  • Learn how limitations of existing technologies in continuous water quality-monitoring networks affect data quality and network maintenance costs.
  • Explore how the evolution of the pH sensor design results in improved stability, data quality and reduced calibration frequency.
  • Discover how improved turbidity sensor design increases linearity and accuracy in clear and high sediment environments.
  • Examine how improved conductivity sensor design coupled with anti-fouling systems improves performance in high biofouling environments.

On the Pulse – Smart meters and acoustic sensors limit non-revenue water loss.

The town of Olds in Alberta, Canada, faced a daunting task. The public works and utilities department, serving the town of approximately 8,000, set out in 2007 to decrease the municipality’s total water usage by 10% by January 2017, using the amount of water it consumed in 2006 as a baseline.

To meet this goal, town officials knew that they would have to address the water that leaked out of Olds’ water delivery system each year. And in this challenge, Olds is far from alone.

According to information published by energy and water resource management company Itron, more than 32 billion cubic meters of treated water leak from urban water supply systems across the world every year. That is equal to more than $18 billion of non-revenue water.

Tsunami Warning! Caribbean

I was able to get my hands on a very lovely little booklet highlighting tsunamis and the Caribbean, in order to inform young persons about tsunamis, the resulting dangers and what should be done to save lives and property. The original book was created by Dr. George Pararas-Carayannis, Ms. Patricia Wilson and Mr. Richard Silcox, with the original illustrations being created by Joe Hunt.

The booklet was adapted for the Caribbean through the Tsunami and Other Coastal Hazards Warning Systems Project, under the Caribbean Disaster Emergency Management Agency (CDEMA), with co-funding from the United States Agency for International Development (USAID), and the story was adapted for the Caribbean by the University of the West Indies Seismic Research Centre. The Caribbean-themed illustrations by Ms, Isiaa Madden-Brownie.

I must say I was very pleased with my find, since many of the books, that can be sourced on the internet for free (a great way to acquire books as a result of budget cuts) are not based on a Caribbean perspective. However, I must say that the Office of Disaster Preparedness and Management (ODPM) and the Caribbean Disaster Emergency Management Agency (CDEMA) do a great job at providing relevant information through their website.

This book is colorful, easy to read and just a joy to behold. So next time you want an easy read to help you dispense information on tsunamis with a Caribbean perspective, just send me an email or check me by my desk.
