PRECISE MONITORING FOR 1,4-DIOXANE

WHERE DO YOU FIND 1,4-DIOXANE?

Used as a stabilizer for chlorinated solvents such as 1,1,1-trichloroethane (TCA) and tetrachloroethene (PCE), it is used in many products including paint strippers, dyes, greases, varnishes, and waxes. 1,4-Dioxane has also been found as an impurity in antifreeze, aircraft deicing fluids and in some consumer products such as deodorants, shampoos, and cosmetics.

FEDERAL AND STATE STANDARDS AND GUIDELINES

• The EPA calculated screening level for tap water is 0.46 μg/L.
• The EPA calculated residential soil screening level is 5.3 mg/kg and the industrial soil screening level is 24 mg/kg.
• The EPA calculated residential air screening level is 0.56 ug/m3 and has an industrial air screening level of 2.5 ug/m3. (Nov 2015)
• The soil-to-groundwater risk-based soil screening level (SSL) is 0.000094 mg/kg or 0.094 ug/kg.
• The National Institute for Occupational Safety and Health (NIOSH) has set 500 mg/L as the concentration that is immediately dangerous to life or health (IDLH) and recommended 1 mg/L as the airborne exposure limit.
• State regulators often use drinking water action levels and health advisories to establish site cleanup goals, and more and more states are requiring lower limits for 1,4-dioxane. Cleanup levels vary by state, ranging from 3 to 50 μg/L in drinking water.
• Colorado has established an interim groundwater quality cleanup standard of 0.35 μg/L. New Jersey has established an interim groundwater quality cleanup standard of 0.4 μg/L.

DETECTION AND SITE CHARACTERIZATION METHOD

The poor purge efficiency by the conventional 8260 method produces sensitivity levels that are 20-100 times greater for 1,4-dioxane than those of conventional VOCs. As a result of the poor sensitivity by conventional 8260 and ever lower federal and local standards, modifications to existing sample preparation procedures and additional methods have been implemented to achieve increased sensitivity.
