The Word on Wells

The U.S. Geological Survey (USGS) released a report in August revealing that 20% of untreated water samples from wells across the U.S. contain concentrations of trace elements exceeding human health benchmarks. Raissa Rocha, editorial intern for Water Quality Products, spoke with Joe Ayotte, USGS hydrologist and lead author of the study, about the report and the occurrence of trace elements in groundwater.

Raissa Rocha: What was the purpose of this study?

Arsenic & Activated Carbon

In 1986, California voters approved an initiative to address growing concerns about exposure to toxic chemicals. That initiative became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known Proposition (Prop) 65. The act requires the state to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 800 chemicals since it was first published in 1987.

Contaminant Removal for Industrial Applications

When the McGraw Hill Data Center in East Windsor, N.J., was being built, the local municipal authority informed the company that it did not have the capacity to support the makeup water for the data center’s condensers or chill water plant. A new well was drilled to serve the plant; however, the groundwater supply had iron and manganese levels that exceeded regulatory limits.

A Modular Treatment Solution

Elevated levels of arsenic, iron and manganese prompted Brandywine Elementary School in Greenfield, Ind., a small town just east of Indianapolis, to seek a treatment solution for the school’s drinking water. The water system is served by one well that provides drinking water for approximately 330 students in kindergarten to fifth grade.

In July 2009, Ladd Eng. Inc. contacted AdEdge Technologies Inc. to provide a proposal for the Brandywine Elementary School in the Southern Hancock School District.

Arsenic Advances

Arsenic and its compounds have been known to be toxic for millennia. Arsenic trioxide (As2O3), often referred to as white arsenic, was a favored poison in the Middle Ages because it had little odor or taste, enabling it to be easily incorporated into the food or drink of a victim. As little as 300 mg can be fatal to an average person.
