Aging infrastructure’s effects on safe urban drinking water delivery
Extensive additional contamination was discovered after the 1996 cleanup plan
The U.S. Environmental Protection Agency (EPA) is proposing to modify a cleanup plan originally issued in 1996 to address soil and groundwater at the AVX property at the Olean Well Field Superfund Site in Cattaraugus County in Olean, N.Y.
Water that enters the soil and flows downward likely will be used again by society. The most common scenario would be that the downward-flowing water recharges the groundwater reserves that are then used as a source of drinking water or for irrigation. Groundwater also often has a hydrologic connection with surface water bodies, so the characteristics of the groundwater can influence aquatic habitats in a lake or river, which then may be used as a source of drinking or irrigation water.
Soil’s benefits as a filter for a variety of contaminants
NSF/ANSI 419: Public Drinking Water Equipment Performance – Filtration evaluates the performance of municipal water filtration technologies in removing Cryptosporidium
Global public health organization NSF Intl. published the first consensus-based American National Standard to evaluate the performance of municipal water filtration technologies in removing Cryptosporidium from public drinking water supplies. The new standard—NSF/ANSI 419: Public Drinking Water Equipment Performance – Filtration—incorporates state and federal regulatory requirements, assisting state regulators in verifying compliance while reducing time and costs for manufacturers by streamlining the testing process.
The H-300-NXT Everpure line of luxury residential water filtration products is certified to NSF/ANSI Standard 401 for the removal of contaminants such as pharmaceuticals, over-the-counter medications and chemical compounds including bisphenol A. The pleated filter membrane is 30% larger than the standard H-300 and provides 50% greater dirt-holding capacity and contaminant reduction capability while maintaining longer filter life. The drinking water system can be installed in kitchens or wet bars and can be connected to appliances.
New facility will help Rwanda's capital city meet current & projected drinking water needs
The Water and Sanitation Corp. Ltd. (WASAC) in Rwanda awarded Culligan Intl. a contract to design and install a water treatment plant to provide drinking water to Kigali, that country’s capital city. WASAC is a government company that provides water to Kigali City and all urban centers of the country.
“Kigali needs about 100,000 cu meters of water per day while water supplied is 65,000 cu meters per day, which implies a shortage of about 35,000 cu meters per day,” said James Sano, CEO of WASAC Eng.
Project for city of Delano will implement biottta technology
AdEdge Water Technologies announced it was awarded and is implementing a biottta (biologically tailored two-stage treatment approach) nitrate removal project for the city of Delano, Calif.
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 treatment system will operate for one year before further evaluation
The U.S. Environmental Protection Agency (EPA) announced that construction of a groundwater treatment system will soon begin at the Smalley-Piper Superfund Site located at 719 Piper Street in Collierville, Tenn. Land clearing and other site preparation activities are currently underway.
