Sounds good Paul.  The Sandy Blvd, 230th Ave to 238th Dr project will acquire part of 
Tax Lot 110 at Townsend Business Park for a right turn lane.  Since that area would 
have to be graded for new pavement, ODOT plans to collect surface soil samples this 
month if we can get the right-of-entry.

Yes, thanks Charles. I had something to do with the arsenic change, If you ever feel the need to talk 
about it, give me a call or email. 
Also, I just learned today I will be becoming the DEQ project manager for Townsend farms again, 
starting next week- so I guess I am your guy.  I will clean up the administrative file starting next week, 
and get the history straightened out.

Thanks,

Paul Seidel

Thanks for sending this.  The clean fill screening level (CFSL) for the DDT compounds 
is 21 ppb.  The CFSL for arsenic in the Portland Basin is 8.8 mg/kg which is quite a bit 
different from what everyone was using back in 2006.

Sending you the two most relevant reports.   I would suggest the potential for some low levels along 
Sandy Blvd. are possible,  and it might be prudent to collect a few composite samples for the purpose 
of decision making. 
The results were not consistent, but there were some samples on lot 10 that had low level detections.

Thanks for trying to find the RI.  I don’t see any linked reports at this site.

HI guys, I do have some institutional history on Townsend.
 
As you know, there is a completed RI in ECSI, then there was an owner change and they stopped all 
work.  
The surface soils throughout all of east Multnomah county are affected by low levels of DDx, dieldrin 
and heptachlor (the usual suspects).
 
We can discuss at your convenience.

Hi Kevin, Paul – Multnomah County plans to widen Sandy Blvd between 230th Ave and 
238th Dr adjacent to the Townsend Farms property.  Widening will require taking a strip 
of Tax Lot 110 for new roadway and sidewalk.  
 
Do either of you know if the topsoil on Tax Lot 110 might be contaminated with 
pesticides adjacent to Sandy Blvd?  I suspect it is.  Who is the consultant currently 
working on that site?
 
Thanks,
