AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
UNICEF to deliver 1,000 tons of chlorine across all 14 governorates in Syria
A large-scale operation is underway in Syria to secure safe water supplies for more than 10 million people — close to half the population, according to UNICEF.
The first four trucks, carrying 80 tons of sodium hypochlorite water chlorination supplies, crossed the Jordanian border into Syria on Feb. 3, heading for Homs, Aleppo, Hama and Idleb. Over the coming weeks, UNICEF will deliver 1,000 tons of chlorine to cities and communities across all 14 governorates in Syria.
Homeowners with a private well as their primary drinking water source are responsible for ensuring the safety of their water. According to the U.S. Environmental Protection Agency (EPA), well owners should test their water at least once a year for bacteria, nitrates, total dissolved solids, pH and any other suspected contaminants. Additional testing should be considered if there have been any repairs to the well, the wellhead gets flooded, there are recurring gastrointestinal problems in the household, or there are any noticeable changes in color, odor or taste.
Procedures for chlorinating a private residential well
Chlorination remains a cornerstone of waterborne disease prevention
This article will focus on three popular forms of chlorine: gas, sodium hypochlorite and dry calcium hypochlorite tablets. Each has advantages and disadvantages relative to cost, convenience, effectiveness, storage and regulatory issues. A look at the pros and cons of each can answer many questions about what's right for your application.
Tablet Chlorination Proves a Viable Alternative
Alternatives to the use of chlorine have received increased interest since concerns over the formation of disinfection byproducts (DBPs) have emerged. However, most of these alternatives (i.e., chloramine, chlorine dioxide and ozone) also produce DBPs. Chlorine still is the most common drinking water disinfectant used today and the one we have the most information about. On balance, the health risks of not chlorinating water appear to be greater than risks associated with DBPs.
Purification of drinking water containing microbiological contamination requires some form of disinfection treatment to kill or render microbiological organisms harmless.
