From: "Chrismarlowe"Date: June 24, 2009 10:29:20 AM EDT Subject: RE: [DCHAS-L] Wastewater testing Julie: The analytical cost for multi-metals analysis may seem high, but I usually find it a bargain. If you need to meet the usual regulatory limits, you'll need a method, like AA, that determines analytes at a low detection limit. You probably don't intend to run samples often enough to acquire, equip, train, and operate such a device at a monthly cost lower than the lab charges you. I suggest that you conduct a full-cost analysis before you buy anything. You may find that commercial labs are your best friend. NOTE: I am a user like you, not a laboratory shill.

Date: June 24, 2009 10:33:31 AM EDT Subject: RE: [DCHAS-L] Wastewater testing Julie, Your first step should be to contact your state environmental regulators to learn what, if any, certifications will be necessary for your laboratory to acquire. Are you monitoring solely for internal company use or will the results be used for discharge permit reporting? Will you be performing work just for your company or will you be soliciting additional work from other companies? If you'll need to be certified, the regulators can provide a listing of which procedures they've deemed as suitable for your analytes. If this work is already being done for your company by a contractor, you could speak with the laboratory director and possibly visit their facility.

The question is what detection limits you need, what type of cost are you willing to pay, and how skilled is your analyst? We have used Graphite Furnace AA, ICP-AES, and ICP-MS (currently what we are set-up for). EPA methods are 200.9 (GFAA), 200.7 (ICP-AES), and 200.8 (ICP-MS). I know that most state's require analysis by approved method listed in 40 CFR Part 136. This was updated in 2007 or 2008 and I know 200.7 and 200.8 are still in there. I'm not sure about SW846 methods. The methods are available on line in PDF format. Standard Methods may also be used and a copy of the methods may be purchased through WEF or AWWA. Lance A.
