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.
The Water Quality Assn.’s Guidelines for Disinfection and Sanitization of Water Treatment Equipment recommend that equipment be disinfected every six months, when it is serviced, after installation and when there is a contamination issue with the source water. If water treatment equipment is not properly sanitized, bacteria can grow and multiply on the inside surfaces of tanks and hoses.
Options for sanitizing RO and softener equipment
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
There are many forces driving water treatment and quality assurance practices: efficacy, reliability, health and safety, cost, practicability, aesthetics and government regulations from government agencies such as the U.S. Environmental Protection Agency. Though effective, there are alternatives to the traditional testing methods prescribed for characterizing and monitoring water quality, saving time and money.
Using ORP to accurately measure disinfectant efficacy
Water is the most important natural resource in our environment, and it is used daily. If water was a pure substance it could be used without concern—but water is far from pure. It contains microorganisms and dissolved minerals, both of which need to be controlled before water can be used safely. Because of its effectiveness against a broad range of microorganisms, chlorine is the primary disinfectant used.
