Pyxis Laboratories provides testing for private industrial and municipal treatment plants requiring periodic waste water permit compliance. The laboratory operates a program including composite and grab sampling as required by discharge permits. We maintain specific permit information and we provide sampling containers for those who perform their own collection, or we can schedule sample collection by our laboratory personnel.
