UCMR4 Sampling Instructions

(Click here to view these instructions as a PDF) (Click here to see video sampling instructions)

 

Contact us with any questions before sampling.  Samples will be rejected if improperly submitted.

 

Clearly label each sample container. Use a permanent marker (Sharpie or similar) to indicate the sampling location and the date and time collected.

Use the proper container to collect your sample and do not rinse out any preservatives present. Specific sample containers are required for all UCMR4 analyses. Samples will be rejected if collected in the incorrect container and will require re-sampling. If you have any questions, please contact us before sampling (1-208-883-2839).

Refrigerate samples or place samples on ice immediately after sampling prior to shipping to lab. Samples must be submitted to the lab within 48 hours of sampling.  UCMR4 protocols have strict preservation and temperature requirements thus samples must arrive at the laboratory cold (<10oC) and in the correct containers or samples will be rejected.

Before submitting your samples to the lab, complete a chain of custody form for each point (EP), distribution system (DS), and water source (SR) .  The additional ‘two bottles per water system’ noted on some tests are collected to allow the laboratory to run matrix spike samples required by UCMR4.
