Certified Erosion Sediment Storm Water Inspector 2026

This Certified Erosion Sediment Storm Water Inspector (CESSWI) practice test includes 27 exam-style questions focused on real construction-site inspection decisions. It is aligned to the CESSWI exam scope used across erosion, sediment, and stormwater compliance roles, reflecting common requirements from state NPDES Construction General Permit programs and SWPPP expectations. You’ll practise core competencies in erosion and sediment control fundamentals, inspection procedures and BMP maintenance, and inspection reporting and recordkeeping. This exam prep is built for inspectors, superintendents, and environmental staff who need confident, defensible field judgments under permit conditions. Use this practice test to quickly identify knowledge gaps, reinforce correct BMP applications, and build test-day accuracy.• Cover erosion and sediment control fundamentals, including terminology, stabilization intent, and practical field indicators of erosion versus transported sediment impacts.• Practise dewatering controls and non-stormwater discharge responses, including concrete washout actions and compliant handling under NPDES CGP non-stormwater provisions.• Master inspection procedures and BMP maintenance, focusing on installation deficiencies like silt fence trenching, repair urgency, and follow-up verification steps.• Assess sediment basin and sediment trap maintenance and performance, including cleanout triggers, dewatering outlet function, and runoff management effectiveness during storms.• Apply sediment control BMP selection and limitations, comparing silt fence, inlet protection, perimeter controls, and understanding where each BMP commonly fails.• Strengthen storm drain inlet protection inspection and maintenance, including purpose/function, clogging indicators, bypass risks, and timely corrective maintenance actions.• Improve SWPPP amendments and change management plus reporting/recordkeeping, using dated photos, corrective-action logs, and inspectio
