She will be responsible for programming, quality assurance, field support, troubleshooting and more
Tobey Strauch recently joined AdEdge Water Technologies LLC as control systems engineer. She will be responsible for programming system control panels, quality assurance, process management, field support, troubleshooting and designing mechanical and electrical interfaces for water treatment systems to remove arsenic, iron, manganese and other contaminants from groundwater.
The conference will cover several topics related to public water issues
The National Ground Water Assn. (NGWA) will offer “Public Water Issues: A Conference for Communities, Contractors and Consulting Professionals,” in Garden Grove, Calif., on May 9.
This one-day conference will address, among other topics:
Source water contains arsenic concentrations above recommended WHO levels
AdEdge Water Technologies recently shipped an arsenic treatment system to the Arica – Pago de Gomez Water Treatment Plant in Chile to reduce arsenic levels of 18 ppb in the water source to below the arsenic maximum contaminant level set by the World Health Organization of 10 ppb.
Companies must continue to monitor groundwater contamination and supply alternate water source if needed
The U.S. Environmental Protection Agency (EPA) has reached an agreement with three oil production companies operating on the Fort Peck Reservation in Montana requiring the companies to address groundwater contamination threatening the city of Poplar’s public water supply system.
Results show effects of industry and agriculture on groundwater quality
Organic solvents were detected at high concentrations in 18% of the aquifer system used for public supply in the San Fernando and San Gabriel basins in California in a U.S. Geological Survey (USGS) study. However, this groundwater treated before delivery to customers to ensure compliance with water quality standards.
By comparison, in most of the California areas previously studied, organic solvents were often detected in groundwater, but not at high concentrations. Statewide, high concentrations of organic solvents were found in less than 2% of the groundwater.
Pennsylvania DEP will host four online sessions in March and April
The Pennsylvania Department of Environmental Protection (DEP) will host online information sessions on implementing Act 13, which Gov. Tom Corbett signed into law in February to further protect the environment and place more stringent regulations on the natural gas drilling industry.
“Act 13 reaffirms our strong commitment to safe, responsible, environmentally sensitive and transparent natural gas development here in Pennsylvania,” said DEP Secretary Mike Krancer. “Our intent with these sessions is to explain the law and answer whatever questions people may have.”
Wellpoint dewatering is the process of removing groundwater temporarily from soils in a localized area to complete the construction of a foundation, pipeline or other below-ground structure or to perform soil remediation.
Typical wellpoint dewatering applications include:
Pump selection and planning for successful wellpoint dewatering
EPA launches website as central information resource on anniversary
This year is the 40th anniversary of the Clean Water Act, the nation’s law for protecting our most irreplaceable resource. Throughout the year, the U.S. Environmental Protection Agency (EPA) and others will highlight the tremendous progress in reducing pollution since 1972, the many milestones along the way, the ways that the job is far from over and the tough challenges faced today and in the future. EPA has set up a webpage, www.epa.gov/cleanwater40, as the central location for information, activities, news and networking.
Four courses will take place before and after event
Four short courses for hydrogeologists will be offered by the National Ground Water Assn. (NGWA) this May in Garden Grove, Calif. Taking place before and after the 2012 NGWA Ground Water Summit, May 6 to 10, the scheduling of these courses will help maximize attendees' travel time and dollars, according to Kathy Butcher, CMP, NGWA's director of professional development.
USGS study used 20 years of data to create new statistical models
A new model predicts that atrazine and its breakdown product deethylatrazine have less than a 10% chance of exceeding the U.S. Environmental Protection Agency’s (EPA) standard for public drinking water supplies in shallow groundwater in about 95% of the nation’s agricultural areas. Atrazine is a commonly used herbicide for weed control in corn and sorghum production.
These findings are based on new statistical models developed from almost 20 years of nationwide water quality monitoring data collected by the USGS National Water Quality Assessment Program (NAWQA).
