Irrigation water testing is important in determining suitable crop types.
Water Sampling Instructions
See below for some sampling guidelines
Water should be collected in a clean 16oz plastic bottle if a general irrigation suitability test is required. Fill the bottle completely and avoid air space. Annual sampling may be necessary to monitor trends. A sampling at the end of summer may indicate water quality at its worst.
Well Water: Collect only after pumping for at least 10 minutes, to allow for a representative sample. It should be taken directly from a good source before any contamination can take place. On occasion, it may be necessary to test the water at different points along the line: before and after the injector pumps and filter station, or at the end of the line to determine residual chlorine or pH for instance. Sample accordingly.
Surface Water: Avoid taking samples directly from the sides of the holding area. They will not be representative of the total body of water.
Identify each sample with an identifying name for the well or water location. Avoid numbering samples simply as 1,2,3 … as it may lead to confusion later. Indicate the analyses desired and provide information that may be of use to the lab in determining problem areas. Other tests may be recommended.
Keep the sample cool (do not freeze), tightly sealed, and ensure that the sample arrives at the laboratory within 24-36 hours. Include a completed water analysis information sheet or cover letter with instructions within the same package. Processing will be delayed if sent separately. Also, include payment if you do not have an established account.
