Oftentimes customers wish to analyze deposits that have formed within a well, pump, piping or water handling system. When submitting such a sample, try to capture a good representation of the deposit and make note of the location of the sampling. If possible, try to preserve the sample in the manner in which it existed – for example, if the deposit was wet, include some of the water and seal in a sufficient container for transport. This will aid in preserving the natural state of the deposit.
Collect a minimum of 25 grams of a deposit. Be sure to note the point at which the sample was collected and any treatment currently performed. Ship in an expedited manner similar to that outlined above. In a similar manner, filter media is often analyzed to better identify the fouling mechanisms present. Collect the media with sufficient water for the sample to remain wet during transport. Filter media samples should be collected when the filter is offline and the media has settled. Ideally, larger filter beds would be sampled in multiple locations to observe the change in mineral and biological conditions throughout the filter. Sample the media in a minimum of two locations: first, near the surface of the media and a second at the mid-point of the total depth of the media. If the media is greater than 3 foot in depth, a third sample at the deepest mark should be collected. Gather approximately 200 grams (0.5 lb) of media per sample, and seal in a container with sufficient water from the filter to keep the media moist and wetted. The sample container should be marked with the filter id, depth of sample, and date sampled. You should not use any type of preservative in the sample and of ship to our lab immediately.
Pressure or kettle type filters should be sampled in a manner that allows an effective representation of fouling present to be observed. Please contact our office to discuss the best sampling procedures for these types of filters.
Exceptions to this sampling method can be made, but should be noted. You may also want to draw a water sample to represent the static conditions within the filter, or pre and post treatment water samples, for more information as needed.
Schedule sampling to occur for shipments to be received Tuesday through Friday.
