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.
Following a recent manufacturers meeting, the industry is focusing on education, best practices and efficiency
According to the Water Quality Assn. (WQA), following a recent meeting with manufacturers over the Arizona Salinity Committee, the industry is emphasizing education, best practices and efficiency.
In April, industry leaders agreed to a set of objectives for the Arizona Salinity Task Force. The committee was established by the state last year. Comprised of public and private stakeholders, it is to report to the legislature with recommendations in September.
Some goals being discussed include:
NGWA said technologies are available to effectively treat arsenic discovered in private household well water
Technologies are available to effectively treat arsenic discovered in private household well water, the National Ground Water Assn. (NGWA) said recently as the federal and state governments conduct testing in Licking County, Ohio.
“While no one wants to have arsenic in the water, the good news is that water well owners who do can treat their water to safe levels with technology that is readily available,” said NGWA Public Awareness Director Cliff Treyens.
The topic of hydraulic fracturing (also known as fracking or hydrofracturing) and its potential effects on groundwater have dominated recent water industry news. WQP Associate Editor Kristin Muckerheide caught up with Marianne R. Metzger of National Testing Laboratories to discuss fracking’s effects and what we can expect in the future.

Located in the heart of Boulder, Colo., the Two Nine North Apartments are eco-friendly luxury units built by Forum Real Estate Group in the late 2000s. Due to the high price per square foot of these apartments, the developer built the residents’ parking garage beneath the complex; however, it is below the water table and posed a threat to the building’s foundation.

Potentially harmful levels of arsenic, uranium, radium, radon and manganese have been found in some bedrock groundwater
Potentially harmful levels of naturally occurring arsenic, uranium, radium, radon and manganese have been found in some bedrock groundwater that supplies drinking water wells in New England, according to a new U.S. Geological Survey (USGS) study.
