EPA Method TO-17 / TO-15

Beacon Environmental can target a broad range of compounds using multi-bed sorbent tubes with low flow pumps or syringes to measure the concentration of VOCs and SVOCs in soil vapor or indoor air in accordance with EPA Method TO-15 and TO-17.  Method TO-17 describes the procedures for collection of samples with sorbent tubes and Method TO-15 allows for the collection of samples by use of a canister or sorbent tube (See Section 1.6 of Method TO-15).

With one sample, highly volatile compounds, such as Vinyl Chloride, can be targeted at the same time that low volatile compounds such as Naphthalene, 2-Methylnaphthalene, Acenaphthene, Fluorene, as well as other PAHs, are targeted.

The use of sorbent tubes expands the capability of what compounds can be targeted in a vapor intrusion or indoor air assessment as compared to collecting samples with evacuated canisters. Data are reported in units of concentration (i.e., ug/m3 or ppbv) with low-level detection limits in the sub ppbv range.

Beacon Environmental’s sorbent tubes coupled with low flow pumps or 100 ml syringes are used to target both chlorinated and petroleum compounds, including diesel range organic compounds at a broad range of sites, including dry cleaning facilities, daycare centers, gas stations, as well as residences.
