EAI Changes Low Level 1,4 Dioxane Reporting Limit

The State of New Hampshire adopted the legislative statute RSA 485-C:4, III to lower the Ambient Groundwater Quality Standard (AGQS) for Low Level 1,4 Dioxane (CAS# 123-91-1) from 3.0 ppb (ug/L) to 0.32 ppb (ug/L) (See Env-Or 603.03(c) intro, Table 600-1 below). This new standard went into effect on September 1, 2018. In response, Eastern Analytical, Inc. (EAI) has lowered their Low Level 1,4 Dioxane reporting limit from 0.25 ppb (ug/L) to 0.2 ppb (ug/L) for all projects required to meet the new AGQS standard. View Table Background Information The compound 1,4-Dioxane has been used as a stabilizing agent in the production of chlorinated solvents to prevent breakdown during manufacturing processes such as textile products, paper, cotton, and automotive coolant. It is also present in many household products like baby lotions, cosmetics, soaps, and shampoos and is part of EPA’s proposed Unregulated Contaminant Monitoring Regulation 3 (UCMR3) list. The New Hampshire Department of Environmental Services (NHDES) added a 1,4 Dioxane sampling requirement to all groundwater discharge permit renewals beginning in 2010. The data gathered since then revealed that about one half of the discharge sites have 1,4 Dioxane at levels above 0.32 ppb far below the existing 3.0 ppb standard limit. The State of New Hampshire took steps to lower the 1,4 Dioxane standard because of the known health risks associated with this compound. Let’s Get Started!
