We have accredited the sampling according to ISO 5776-10 however, there is an obligation to perform the PT in next 5 years. What are your experiences?
Suzana - you may be familiar with these already but the following links might help:
1. http://fapas.com/proficiency-testing-schemes/leap/index.cfm. This might be a very useful site to visit.
2. The following database may also be very useful http://www.eptis.bam.de/en/index.htm
3. Recent poster at EuroChem (copy and paste the full link)

Dear Suzana, I also think this document may be useful:

a great number of proficiency samples are available from

Dear colleagues,
I thank you very much for your answers.
However, maybe I did not pose the question clearly enough.
As for the PT for particular parameters, I am very well acquainted, we are participating intensively, the last 7 years especially. We did different things like, Fapas, also have ordered from Sigma Aldrich their PT samples, participated in some regional Balcan (PT Aquas) testings etc. We do get very nice results and we are confident since the Institute is well equipped and the technicians are well educated, while the engineers are following every step of the procedures.
However, what the BATA (Bosnian accreditation body) is asking us for is the "sampling technique PT". As far as I understand, this would be the kind of PT where few participants would set up their equipment at the same location (for example some effluent discharge place or the river), and than perform the sampling at the same time.
Than, the same set of the parameters (usually, the basic physico/chemistry and nutrients) will be analysed in the lab and compared statistically.
This way, all the participants would prove that they are following the certain standard (for us the ISO 5776-10) and that they are performing the sampling with certain measurement uncertainty.
If somebody has some information, I would be very thankful. We are even thinking about organizing one at one of our rivers in next year which is quite realistic.
The PT from the LEAP Scheme EFF:
Effluent, Wastewater, Contaminated Land and Hazardous Waste

The principal problematic situation with the sampling is that the sample is an heterogeneous situation because that the famous phrase says "the water on the river never is the same". On our experience the best PT as from ielab oDpto Comercial

The proficiency testing of wastewater sampling is organized by the National Institute of Chemistry in Ljubljana (Slovenia) each year. Link is Magda Cotman ([email protected]).
There is an article "Proficiency testing of wastewater sampling: What did we learn?" in Accreditation and Quality Assurance.

Dear Alenka, thank you for the very useful information.
We will consider the participation soon.
We provide profiency testing schemes at our institute - maybe we can help you or others. We provide also sampling PT schemes (at a swimming pool). see http://www.kwrwater.nl/page.aspx?id=10123 Good luck!
