Some of you will soon be getting a call (if you haven’t already) from Tony as he sets up Split Sampling for the 2005 season. Split Sampling is one of the ways that we monitor the quality of work that you, the volunteers, are doing. By showing that the data generated through volunteer efforts are of high quality, we can ensure the continued use of LMVP data by the state to meet monitoring requirements of the Clean Water Act.

Participating in a Split Sample is easy; Tony will schedule a time for someone from the University to meet with you during a scheduled sampling. The LMVP representative will accompany you out to your site and observe as you make field readings and collect your composite sample. Once you have filled your bottle from the composite container (a.k.a.—the bucket), the LMVP staffer will also fill their bottle from the composite container. From here you will process and store the sample as you normally would, while the split will be brought back to the University for processing and storage.

Once data are generated, comparisons will be made between the Split Samples. Differences in results would suggest that there was a problem with processing or storage that has had a negative impact on the data. Similar results in Split Samples would show that procedures used by volunteers do not influence the data. The state currently considers LMVP data to be of the highest quality. By being careful, diligent and a just a bit retentive, volunteers can collect high quality data. The results from Split Sampling will hopefully provide proof of that quality.
