At first glance, this issue of Water Quality Products might seem to have a rock ‘n’ roll theme, with phrases like “rock on” and “heavy metal” peppering the article titles — but unfortunately the issue at hand is anything but rock ‘n’ roll.
The focus of these articles is heavy metals, contaminants that lately have been making more waves than usual within the industry. Between the quickly approaching deadline for the new federal low-lead law and the recent release of California’s proposed chromium-6 limit, it is one that will continue to be a concern.
The town of Newport Center, Vt., is a small community of approximately 1,500 residents located just south of the U.S.-Canada border. A combination of drought and increased water use required the drilling of a new well for the community to supplement the two wells already in service. Water quality testing of the new well found arsenic levels at 20 ppb, well above the drinking water standard set by the U.S. Environmental Protection Agency (EPA) and the state of Vermont of 10 ppb.

Study finds that conditions in some aquifers enable contaminants to remain in groundwater longer
Key factors have been identified that help determine the vulnerability of public supply wells to contamination. A new U.S. Geological Survey (USGS) report describes these factors, providing insight into which contaminants in an aquifer might reach a well, and when, how and at what concentration they might arrive.
About one-third of the U.S. population gets its drinking water from public supply wells.
The SenSafe Water Metals Check test is a quick, accurate, inexpensive way to determine toxic metal levels in tap water. This patented test strip develops red in the presence of toxic metals above 10 ppb in only two minutes. It detects toxic +2 valence metals found in tap water. Because of its detection sensitivity, it confirms the need for water filtration or remediation. The test can be purchased for $19.99 for 50 tests or $5.99 for six tests with instructions and a color chart.
EPA to cleanup Nassau County groundwater contaminated with harmful VOCs
The U.S. Environmental Protection Agency (EPA) announced its proposed plan to clean up an area of contaminated groundwater within the New Cassel/Hicksville Ground Water Contamination Superfund site in the towns of Hempstead, North Hempstead and Oyster Bay in Nassau County, N.Y. Groundwater throughout these areas is contaminated with harmful volatile organic compounds (VOCs), which are often found in paint, solvents, aerosol sprays, cleaners, disinfectants, automotive products and dry cleaning fluids.

New reports of contaminant point to need for "final barrier" protection
With news reports about possible spikes in nitrate levels in drinking water, residents can ensure protection with final barrier systems in the home, according to the Water Quality Assn. (WQA).
According to reports, Burkburnett public works in Texas is investigating a possible spike in nitrate levels in the city’s drinking water.
CH2M Hill treated 1.4 billion gal of groundwater between October 2012 and June 2013
U.S. Department of Energy (DOE) contractor CH2M HILL Plateau Remediation Co. (CH2M HILL) has exceeded this year’s goal for treating 1.4 billion gal of contaminated groundwater at the Hanford Site in Washington state.
Tetrachloroethylene and other volatile organic compounds are polluting groundwater
The U.S. Environmental Protection Agency (EPA) announced a proposed plan to clean up soil at the Ellis Property Superfund site in Evesham Township, N.J., which is contaminated with tetrachloroethylene and other volatile organic compounds (VOCs) that are polluting groundwater underlying the site.
Industrial water treatment can be classified by the following categories (not including wastewater treatment, which is a separate topic):
- Process water treatment;
- Boiler water treatment; and
- Cooling water treatment.
Water treatment is used to optimize most water-based industrial processes, including heating, cooling, processing, cleaning and rinsing, so that operating costs and risks are reduced.
