More than a billion people in the developing world lack safe drinking water – an amenity those in the developed world take for granted. Nearly three billion people live without access to adequate sanitation systems necessary for reducing exposure to water-related diseases. The failure of the international aid community, nations, and local organizations to satisfy these basic human needs has led to substantial, unnecessary, and preventable human suffering. This paper argues that access to a basic water requirement is a fundamental human right implicitly and explicitly supported by international law, declarations, and State practice. Governments, international aid agencies, non-governmental organizations, and local communities should work to provide all humans with a basic water requirement and to guarantee that water as a human right. By acknowledging a human right to water and expressing the willingness to meet this right for those currently deprived of it, the water community would have a useful tool for addressing one of the most fundamental failures of 20th century development.
Glyphosate and AMPA in drinking water
Carcinogenic or not? The broad-spectrum herbicide glyphosate is used all over the world in agriculture. Alongside farming, the chemical is also used for weed-killing in domestic gardens and in public and private spaces kept free from «vegetal invasion», such as railway tracks. Glyphosate has been used since the 1970s in pesticides and was hitherto thought to be harmless at typical levels of exposure. However, since the International Agency for Research on Cancer (IARC) – the specialized cancer-re...
Monitoring Nitrates in Drinking Water and Wastewater
Nitrate is present in high levels in wastewater due in part to the high nitrates present in human sewage but also from some types of industrial effluent entering the municipal sewer system. Nitrate is also a very common contaminant in both surface water and ground water. Nitrate occurs naturally in source water as a result of decaying plants. However, there are other manmade sources of nitrate than can increase the presence of nitrate in source waters to dangerous levels. Agricultural sources of nitrates include...
Adsorption of methylene blue using modified adsorbents from drinking water treatment sludge
This study aims to explore the preparation and application of alum sludge (AS) and mud sludge (MS) from a drinking water treatment plant to remove methylene blue (MB) dye from aqueous solution. The sludge (MS and AS) was treated by chemical and physical activation to obtain new adsorbents. The adsorption experiments were carried out under different conditions of initial dye concentration (50–100 mg/L) adsorbent dosage (0.05–0.25 g), solution pH (3–9), temperature (20–60 °C) and contact time (20–90 min). Scanning...
How Does Lead Get into Drinking Water? How Can Local Municipalities Remove It?
In light of the Flint water crisis—when, in 2014, Flint officials changed the city’s water source from the Detroit Water and Sewerage Department to the Flint River, leaching unsafe levels of lead into the public water supply due to improper treatment—many people are wondering if the same thing could happen in their own communities and homes. Some folks believe this could be the tip of the iceberg, and that with older piping carrying municipal water to local houses, schools, and workplaces, more...
Water Reuse Terminology
All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology allow communities to capture and reuse water for many different purposes. The level of treatment employed depends on the...
