|STEPS FOR COLLECTING WATER SAMPLES FOR AN IRRIGATION-SUITABILITY TEST: |
- A clean plastic container should be used. Rinse the bottle (including the lid) several times with the water to be tested. If desired, the laboratory will supply sampling kits, including clean plastic bottles.
- To reflect what the water quality is at the time of application, collect sample from the pumping station or within the irrigation system.
- If a system of irrigation wells (ground water) are being used, sample each well separately. This will qualify the water specifically from each well. (This is important if pumping into a holding pond.)
- When collecting sample from the irrigation system, let water run for two to three minutes before collecting the sample. (This will purge static water from the system.)
- When sampling from a pond, collect water from the pumping station. If possible, DO NOT collect the water from the side of the irrigation pond, sediment will act as a contaminant.
- Fill bottle and eliminate all head space. Be sure lid is tight so that samples do not leak out during transit. Laboratory needs at least 100 ml (about 6 ounces) of water.
- If using glass, be sure to use adequate packaging.
- If possible, collect and ship sample/samples the same day.
- Be sure bottles are clearly identified and necessary paperwork is completed before shipping.
