A water sample should always be taken from a non-swing, non-spray cold water tap, with the aerator removed. Except for a first draw lead or copper test, all samples should be taken after the water has run hard for 5-10 minutes. If a house has been recently vacated, the water should be run long enough to draw in fresh water from the well. If the house has been vacant for an extended period of time, the well should be exercised repeatedly over a few days before taking a sample.

Adsorption Filters utilize a special media that is designed to adsorb dissolved materials from the water. They are especially configured without a backwash as the media type is one that will not release the contaminant that is removed from the water.
