Local levels: Grade I Treatment License; Grade II Treatment License; Grade III Treatment License; Grade IV Treatment License
Mandatory drinking-water licensing. Official sources establish separate treatment examinations and recommend ABC/WPI preparation materials, but do not explicitly identify standardized WPI exams, customized ABC exams, or state-authored exams. Local grade numbering does not establish WPI class correspondence.
No state-matched course is linked for this stream yet.
Program has been mandatory since 1957; the Drinking Water Advisory & Operator Licensing Committee oversees it.
Sections V and X identify Treatment Grades I–IV. Section IX.D requires separate treatment and distribution examinations for Grades I–IV; it does not name the exam developer or standardized series.
Recommended references are the study manuals referenced in ABC exam-preparation Needs To Know Criteria. Arkansas PWS rules and the Arkansas PWS Compliance Summary are additional recommended materials; no standardized-exam adoption statement appears.
Exam route under review
Program authority: Arkansas Department of Energy and Environment, Division of Environmental Quality (DEQ), Enforcement Branch; Wastewater Licensing Committee
Local levels: Municipal: Apprentice, Class I, Class II, Class III, Class IV. Industrial: Apprentice, Basic, Advanced.
Mandatory treatment-plant licensing has separate municipal and industrial tracks. Apprentice is listed as a license category, not established here as an exam level. Municipal Class IV has a different application lead time, but that does not prove a different exam vendor or standardized exam. No opened source establishes standardized/customized ABC provenance or state-authored exams for any class.
No state-matched course is linked for this stream yet.
Enforcement Branch administers licensing; all wastewater treatment plants must have a properly licensed operator. Lists municipal Apprentice/Class I–IV and industrial Apprentice/Basic/Advanced. Class IV applications require 30 business days rather than five for other exams.
Committee adopts competence criteria for operator classifications and approves training; its executive secretary administers licensing examinations. The provision does not identify a standardized exam series. Official code page last updated October 1, 2026.
Exam route under review
Program authority: Arkansas Department of Health (ADH), under the Arkansas State Board of Health and Drinking Water Advisory & Operator Licensing Committee
Local levels: Small System Distribution License (facility classification: Very Small Water System); Grade I Distribution License; Grade II Distribution License; Grade III Distribution License; Grade IV Distribution License
Mandatory licensing, distinct from treatment. Rules use both Very Small Water System and Small System Distribution terminology. Neither the separate exams nor WPI preparation links establish standardized or customized exam provenance. The small-system route must not be represented as WPI Class 1.
No state-matched course is linked for this stream yet.
Section V.E lists Very Small Water System and Grades I–IV distribution facilities; Section X lists Small System Distribution License and Grade I–IV Distribution Licenses. Section IX requires distinct distribution examinations and a separate very-small-system examination.
Lists Treatment, Distribution, Very Small System - Need To Know and Math Formula Sheets through WPI, alongside Arkansas Public Water System rules and compliance materials. These are preparation links, not an explicit standardized-exam designation.
Exam route under review
Program authority: Arkansas Water Environment Association (AWEA), Voluntary Certification Program Committee (VCPC)
Local levels: Class 1–Class 4, voluntary Wastewater Collection System Operator certification
AWEA offers a separate voluntary collection-system certification program, not the DEQ mandatory treatment license. Its own administering-authority page says ABC reviewed and approved the program, but does not say its exams are standardized ABC/WPI or customized ABC. Do not infer exam identity from program approval or from drinking-water evidence.
No state-matched course is linked for this stream yet.
Identifies an AWEA-sponsored tiered voluntary program administered by VCPC, beginning with Class 1 and ending with Class 4. Says the program was reviewed and approved by ABC; does not identify the exam product.
