What we're building next for H2O CERT
Practice questions and exam prep for Water Distribution operator certification. Grades 1-2 now live (system components, maintenance, safety, laboratory, administration, and math); grades 3-4 in progress.
Practice questions and exam prep for Water Treatment operator certification.
Expanding beyond South Carolina to other states whose certification programs follow ABC (Association of Boards of Certification) standards.
Full practice question bank, exam simulations, and math templates for Class I–IV Wastewater operators (Physical/Chemical and Biological tracks), covering administration, maintenance, laboratory, safety/chlorine, and process-specific content at every grade level.
In-app tools to report bugs or flag questions that need review, so the question bank keeps improving.
