Testing the waters: 1,4-dioxane in North Carolinas Cape Fear River Basin

Environmental engineer Detlift Kanape investigates the presence of 1/4 dioxane, a probable carcinogen, in the Cape Fear River Basin, North Carolina's largest watershed. Supported by a National Science Foundation grant, Kanape's team confirms high contamination levels, posing health risks. Current water treatment technologies fail to remove the chemical, prompting efforts to collaborate with industries to address pollution at its source. The team also explores the effectiveness of home filtration systems and works with policymakers to enhance water testing and treatment standards.

What is the primary concern associated with 1/4 dioxane in the Cape Fear River Basin?

• It is a natural component of the watershed.

• It is a probable human carcinogen.

• It is a nutrient for aquatic life.

• It enhances the taste of water.

Why is it difficult to remove 1/4 dioxane from water using current technologies?

• It is beneficial for water quality.

• It is resistant to typical water treatment processes.

• It is not detected by standard tests.

• It is too expensive to remove.

What is one of the goals of Kanape's team in addressing the 1/4 dioxane issue?

• To increase the production of 1/4 dioxane.

• To develop methods to treat the chemical at its source.

• To ban all industrial activities in the area.

• To promote the use of 1/4 dioxane in cosmetics.

What is being investigated as a potential solution for removing 1/4 dioxane from home water supplies?

• High-cost industrial filters.

• Low-cost carbon filters.

• Chemical additives.

• Boiling water.

Who is Kanape collaborating with to improve testing and treatment standards for 1/4 dioxane?

• International environmental organizations.

• Water treatment plant managers and state policymakers.

• School teachers and students.

• Local farmers and fishermen.
