The EGLE Drinking Water Laboratory has improved its testing methods for these test groups, requiring additional laboratory instrumentation and an additional bottle to perform the testing. The laboratory is changing to a 2-bottle test kit on April 1, 2024 for these test groups to improve quality control and testing efficiency.
In addition to this bottle change, the CPM2 test group will now use the Unit 36ME bottle, and the Unit 32 bottle will now be used in place of the larger Unit 33 sample bottle for other test groups.
