Thank you. Enjoy your time away, okay?!
Hi Linda,
| have attached anupdated list oflabs that have said they can test for GenXand other related
compounds.
There may besome benefits tousing Test4merica.
* d—[if !suppurtLiris]—»«!—[endU]—>Historica| comparison to Dr. Knappe'sdata
w x!—[if !supportLists]—><!—[endif] —>Testprocedures, equipment and reporting levels are similar
to EPA and historical data
However, even though samples were split between only two labs, the first set of trip spikes seems to
support that TestAmericamay generally bebiased onthe high side.
Eurofins has a Raleigh hub and provides pickup and shipping which may be helpful. In addition, Chris has
said he has had very good experiences with Eurofins in the past in terms of transparency and customer
service.
Happy to discuss further.

Interested in your thoughts on which commercial lab we should use if we decide to directly contract
with a commercial lab for GenX work in the future.
