The sample date listed on lab paperwork is a suggested sample collection date. You have the entire month of your given sample month to take your DBP sample. Please note, though, that DBP samples must arrive at KHEL no later than Wednesday within the same sample week, with only 24 hours in transit. Samples therefore must be collected on a Sunday, Monday, or Tuesday in any given week of your sampling month. Also, samples must be completed within your assigned sampling month. Samples collected outside of your assigned sampling month are only allowed if operational procedures (such as a chlorine burnout) coincide with your sampling schedule and if KDHE is notified of these procedures before they occur.
