Elevated levels of arsenic, iron and manganese prompted the Resort Village of Kannata Valley in Saskatchewan, Canada — a community of 149 households situated on the north shore of Last Mountain Lake, approximately 50 km northwest of Regina — to seek a treatment solution for its drinking water. The community water system is served by an artesian well that provides drinking water for approximately 250 residents. In November 2009, AdEdge Water Technologies LLC was selected by the community to supply an arsenic, iron, manganese and turbidity treatment system.

The resin removes hexavalent chromium from groundwater
ResinTech Inc. received the Water Quality Assn.’s Gold Seal of approval for its chromate-selective resin, ResinTech SIR-700. ResinTech SIR-700 now meets NSF/ANSI-61: Drinking Water System Components — Health Effects for use in all potable water applications.
SOR has achieved the IP68 rating in up to 100 ft of continuous submersion for the 805PT electronic pressure transmitter. The transmitter will provide precision depth measurements in liquid applications such as well monitoring, groundwater and surface water measurement, as well as municipal and industrial applications. It comes with a three-year warranty.
Foundation hopes to raise $3 million over 18 months
The National Ground Water Research and Educational Foundation (NGWREF) has launched a major fundraising campaign to underwrite national and international groundwater projects.
“This is the first major campaign the foundation has undertaken in nearly 16 years. Our ultimate goal is to raise at least $3 million over the next 18 months,” said Steve Schneider, MGWC, president of NGWREF. Schneider stressed that 100% of funds raised will go to foundation programs.
Alley will assume his post in mid-November
William M. Alley, Ph.D., has been named director of science and technology for the National Ground Water Assn. (NGWA).
Alley recently retired after 18 years as chief of the Office of Groundwater at the U.S. Geological Survey (USGS). He will assume his NGWA post Nov. 13, 2012.
A congressional briefing led by the U.S. Geological Survey (USGS) has spotlighted the importance of monitoring the nation’s groundwater quantity and quality.
Representing USGS at the July 27 briefing was Bill Cunningham, acting chief of the USGS Office of Groundwater.
Groundwater is often referred to as an out-of-sight, out-of-mind resource, yet 78% of community water systems, nearly all of America’s private household wells and 42% of agricultural irrigation water is supplied by groundwater.
Many of the public and private wells sampled contained natural or manmade contaminants
At least one contaminant was found at levels of human health concern in about one-third of untreated groundwater samples collected from wells in the Cambrian-Ordovician aquifer system, according to a recent report by the U.S. Geological Survey (USGS). When radon concentrations greater than 300 picocuries per liter are included, 64% of wells sampled contain a contaminant concentration above a human health benchmark.
The state of Ohio is collecting water samples from homes and public water systems to determine arsenic levels throughout the region
The state of Ohio is determining regions with elevated arsenic levels in groundwater by collecting water samples from homes and public water systems. State health officials are using workshops to educate the public about the dangers of ingesting arsenic and offering tests for arsenic contamination in well water. The U.S. Environmental Protection Agency (EPA) regulates public water systems, but it does not have the authority to regulate private drinking water wells.
Statewide study surveyed groundwater for more than 300 contaminants
Nitrate was detected at high concentrations in one-quarter of the aquifer system used for the Inland Empire public water supply. Additionally, high concentrations of perchlorate were found in 11% of the aquifer system, and in moderate concentrations in 53%. This aquifer system includes the Upper Santa Ana Valley, San Jacinto and Elsinore groundwater basins in California. High nitrate and perchlorate concentrations were not found in the Elsinore groundwater basin.
