ALERT: Required Chlorine Testing

To our valued customers:

To be TNI (The NELAC Institute) compliant as of 2009, all water samples must have a chlorine residual test performed and recorded on the sample form. All public samples including Distribution, Raw, Special, and Construction must have had a chlorine test performed and recorded prior to turning in their sample for testing.   The result of the chlorine test can be zero but it must be recorded on the test form. Any public sample that does not meet the requirement cannot be accepted by the lab for testing. Private samples that do not show a chlorine test having been performed can be tested but the sample result will show on the test form that the sample is unsatisfactory to TNI because no chlorine test was done.
