I have established a new website, which will contain nothing but math practice tests for introductory-level water treatment facility operator certification exams. I am personally writing all of the test questions on this site, so the questions will be completely original and will not be the same questions that are found on standard water school practice test handout sheets.
The site address is http://water-treatment-math-practice-tests.blogspot.com/
