B--R10 SEMD: Selenium Speciation Sample Analysis

The US Environmental Protection Agency’s Region 7 Contracting Office is seeking information from laboratories capable of performing specialized selenium speciation analysis on environmental samples from the Ballard Mine Superfund Site. The required services include the detection and quantification of both organic and inorganic selenium species in matrices such as filtered and unfiltered water, sediment, soil, and plant tissue or periphyton, with a key performance requirement of achieving aqueous detection limits of 4 ng/L or 0.004 ug/L. This request is for market research purposes only and does not constitute a solicitation, quotation request, or binding procurement; responses are not offers and will not be accepted as such. All submissions must be sent electronically to Lindsay Savage at savage.lindsay@epa.gov with a specific subject line format and must include a completed Vendor Response form and supporting technical documentation or literature. The opportunity is identified under solicitation number 68HE0726Q0033 and is classified under NAICS code 541380 for environmental consulting services. The deadline for responses is July 21, 2026, at 9:30 PM ET, and all information must be submitted by that time to be considered. The contracting office is located in Lenexa, Kansas, but the work will be performed at the Ballard Mine site in Seattle, Washington. Point of contact for questions and submissions is Lindsay Savage, who can also be reached by phone at 913-551-7565. Participation in this market research will assist the EPA in planning future acquisition strategies for analytical services related to selenium speciation in complex environmental matrices.
