Julie, Molalla will take 1 sample this afternoon during the rise of this upcoming rain event. A second sample will be taken tonight at the time we get turbidity alarms, that usually correlates with the peak of the event. If we see no alarms, we will take the sample tomorrow morning, 7:30am. The third sample we will take during the tail end of the event tomorrow afternoon. Molalla will use 1 Litre non-autoclaved Nalgene samples bottle, and place them on ice (or refrigerator). We will also provide hourly raw water turbidity information. River flows are measured on the USGS gauge station in Canby, which I’m sure Kurt has already. We also have a monitoring station on Trout Creek if he needs additional information. Kurt can pick up the bottles tomorrow afternoon, I expect they will be here at the City Shops, 920 Toliver, Molalla. But call ahead to confirm. My number is below.

Respectfully,

Andy Peters

Guys,

They need samples taken and it is after hours stuff. I just spoke with Julie (503.867.5999) and she said that Kurt can deliver bottles today if needed. They would also like a sample taken now before the rain event starts if possible. Call Julie or Kurt if you have any questions. Thanks.

Hi Gerald and Ryan –

USGS and other local partners are working with water systems affected by the wildfires to collect samples to characterize the impacts on drinking water systems and their source watersheds. With the rains expected today/tonight, they are hoping to collect “first flush” samples and wondered in Molalla could collect samples for USGS analysis. As you can imagine, resources are spread pretty thin right now as they are responding in multiple watersheds along the cascade crest.

Would you be willing to collect the following samples tonight/tomorrow:

• * 1 L samples during rise, peak, and fall in flow
• * Record turbidity as available
• * USGS (Kurt Carpenter) would pick up samples tomorrow, just keep on ice

Samples would be analyzed for things like turbidity, suspended sediments, organic carbon, nutrients, trace ions, nutrients, DOC, TOC.

USGS contact is Kurt Carpenter, Research Hydrologist – he is copied on this email. Kurt also is a part of the NRCS NWQI assessment Technical Advisory Team. Email is kdcar@usgs.gov

Please contact me to discuss or if you have any questions . You can reach me on my cell at 503-867-5999 or via email.
