A Valuable Process Control Test that is Quick, Easy, and Accurate
The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM).

Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.
