Not knowing your DO measurement method (Clark cell, optical probe, Winkler titration), it is hard to say if the collection method would have an impact greater than the measuring method&#8217;s accuracy. You&#8217;d have to do a lot of splashing and sloshing to exceed the Clark cell accuracy of most meters (anywhere from 0.2 mg\/L to 0.5 mg\/L for the better cells). Don&#8217;t remember off the top of my head the Winkler accuracy and precision. What I do remember is that the quality of the reagents and lighting to see the color change is important to that method.<\/p>\n<p>If you have to have non-surface DO, then, yes, a collection bottle is needed.<br \/>\nI just hope they rinse the bucket in stream water if they are also collecting nutrient chemistry samples.<\/p>\n<p>Just my 2 cents. \ud83d\ude42<br \/>\nAnn Schenk<br \/>\nNatural Resource Biologist III<br \/>\nMaryland Department of Natural Resources<br \/>\n580 Taylor Ave., C-2<br \/>\nAnnapolis, MD 21401<br \/>\nphone: 410-260-8609<\/p>\n<p>&nbsp;<\/p>\n<p>Date: Fri, 23 May 2008 13:19:12 -0400<br \/>\nFrom: Jeffrey Schloss<br \/>\nSubject: Re: [volmonitor] Fwd: seeking homemade water sampler<\/p>\n<p>With regard to collecting a proper DO sample for titration. If you carefully deploy a bucket that is fitted with a spout and tubing that allows you to fill a BOD bottle (specially designed not to trap air bubbles when closed) from the bottom up- and you count how long it takes to fill the bottle up and allow for 2 to 3 full volumes of water to flush through you should have a reasonably uninfluenced\/disturbed sample to work with. Just remember that this sample only represents the surface water conditions if you are dealing with a system that has any temperature, current, or density (do to dissolved solids\/salts) stratifications.
