Printable FE Environmental Lookup Map
FE Environmental Handbook 10.6 Page Guide
Use this as a compact navigation sheet while you practice. It does not reproduce the NCEES handbook. It points you toward the official handbook sections that are most likely to matter for FE Environmental problems, then gives you search cues so you can find the right equation faster.

Pages Worth Memorizing by Location
- Environmental Engineering pp. 324-366: the main FE Environmental lookup lane for water, wastewater, air, groundwater, waste, risk, and environmental chemistry.
- Fluid Mechanics pp. 187-214 and Civil Engineering pp. 271-323: use these with hydraulics, hydrology, open-channel flow, pumps, and groundwater setups.
- Chemistry and Biology pp. 92-100: useful for pH, equilibrium, stoichiometry, biology, and chemistry-heavy treatment questions.
- Ethics, Safety, and Economics: small page ranges that can turn into quick points if you know where they live.
Sections People Waste Time On
- Searching the whole PDF for broad words like "water" or "air" instead of using terms like "BOD," "Manning," "Darcy," or "Gaussian plume."
- Looking only in Environmental Engineering when the controlling flow relation lives in Fluid Mechanics or Civil Engineering.
- Starting calculator work before converting concentration, flow, detention time, and mass-rate units.
- Reading the handbook passively instead of solving with the handbook open and timing each lookup.
First-Week Lookup Drill
- Open your official NCEES FE Reference Handbook 10.6 copy beside your practice set.
- Before solving each problem, name the lane: water/wastewater, hydraulics, hydrology, groundwater, air, solid waste, chemistry, risk, or shared FE.
- Jump directly to the page range above. Avoid global search until you have tried the likely section.
- Write down the shortest useful search term: "BOD," "Manning," "Darcy," "Gaussian," "alkalinity," "detention."
- After 20 problems, circle the three terms that cost the most time. Those become tomorrow's drill.
How FE Test Prep Uses This Workflow
Our practice problems label the problem type, include quick formula references, and show calculator steps when they matter. The point is not to memorize every page. The point is to recognize the setup, know where to look, and then execute cleanly under time pressure.
