The failure to provide safe drinking water and adequate sanitation services to all people is perhaps the greatest development failure of the 20th century. The most egregious consequence of this failure is the high rate of mortality among young children from preventable water-related diseases. This paper examines different scenarios of activities in the international water arena and provides three estimates of the overall water-related mortality likely to occur over the next two decades.
Guide to Removing Arsenic from Drinking Water
It’s said that the human body is made up of almost 60 percent water. Is the water you’re putting into your body pure? Many people are unaware of the chemicals and compounds that are seeping into their drinking water and wreaking havoc on their internal systems. Arsenic, for example, can be found in many different areas. In the Northeast especially, well water is more likely to be contaminated with this deadly element. Arsenic removal is possible with the right system and information. Here is everything...
How to Remove Arsenic from Your Water
Do you know what’s in your drinking water? You might be surprised to find that dangerous chemicals and elements are coming out of your kitchen tap. In most areas, arsenic can be found in drinking water. Regions in the Northeast usually have a higher level of arsenic found in drinking water due to the bedrock. While it might not seem like a big deal, arsenic can cause major problems. Here is everything you need to know about this dangerous chemical and arsenic water treatment systems. The Dangers of...
The Benefits of Biological Treatment for Drinking Water
The biological treatment of drinking water is undertaken using both organic and inorganic contaminants, and can be used to treat groundwater and surface water. These contaminants, contrary to what the name implies, are applied to strip away the factors that make the water unsafe for drinking until it is potable—meaning drinkable. If you would like to learn more about the benefits of biological water treatment, then read on to discover more about why it is a good treatment option and what obstacles are...
Nitrate Analysis of Water Samples Using a Benchtop UV-Vis Spectrophotometer
Nitrogen is naturally found in groundwater and surface water in the form of nitrate, nitrite, or ammonium. The EPA has established a maximum contaminant level of nitrate-nitrogen in potable water of 10ppm. This application presents results of UV-Vis analysis of nitrate concentrations in drinking water, ground water, and industrial wastewater, showing that the manual colorimetric method is suitable for analysis of nitrate contamination in water systems. The data included is part of a data set being used to...
[Technical Paper] Biomass Evolution in Full-Scale Drinking Water Filters
After nearly two-years of work, we could advance our understanding of ATP measurement in drinking water biofilters. I will describe some of the background and key results from the study below – more information is provided in the Journal AWWA December 2016article. Background of the Study. Amina Stoddart, a PhD student at our Water Studies lab at Dalhousie, led a project that collected weekly ATP samples from full-scale filters. Her monitoring program was used to evaluate the start-up of full-scale anthracit...
