EPA LEAD INSPECTOR EXAM 2026/2027 ||
ENVIRONMENTAL SAFETY & HAZARD CONTROL REVIEW ||
VERIFIED QUESTIONS & ANSWERS || COMPLETE STUDY
GUIDE || HIGH-YIELD TEST BANK || GRADED A+
Lead-based paint (LBP) - CORRECT ANSWER -Any varnish, shallac, or
coating that contains either- 1.0 mg/cm2 - 0.5 % by weight - 5000 ppm - Older
instruments could not read accurately at 0.7, so the lead standard was updated to
1.0
Dust sample clearance values - CORRECT ANSWER -- Floors: 40 μg/ft2 >
10 μg/ft2 (10 μg/ft2 in NY) - Windows: 250 μg/ft2 > 100 μg/ft2 (50 μg/ft2 in
NY) - Window wells (troughs): 400 μg/ft2 (100 μg/ft2 in NY) - Samples must
be at 1 sq ft > 2 sq ft (can be reduced to 1 sq ft if within 10 μg)
EPA Soil Regulations - CORRECT ANSWER -- 400 ppm for
playgrounds/children's areas - 1200 ppm for rest of yard - There must be 9 sq ft
of soil to classify with soil testing - At 5000 ppm, MUST remediate/abate
(remove & replace, paving, or bioremediation)
Lab sampling technique - CORRECT ANSWER -- AAS (Atomic
Absorption Spectrometry) - Sample is placed into a furnace and vaporized ...
light is shone through to give a quantitative result
XRF - CORRECT ANSWER -- X-ray fluorescence - Utilizes radioactive
isotopes (unstable material trying to reach stability) - Cobalt-57 (half-life of 9
months) and cadmium-109 (half-life of 15 months) are the two sources (where
radiation originates) - Emits gamma rays but will read X-rays (backscatters) -
Ionizing radiation from the removal of electrons due to interactions with
radiation
LBP Hazard - CORRECT ANSWER -ANY condition that causes exposure
to lead
, LBP inspection - CORRECT ANSWER -a surface-by-surface investigation
to determine the presence of lead
CPSC - CORRECT ANSWER -- Consumer Product Safety Commission -
Set a lead paint standard: cannot contain 0.06% lead by weight ... updated to
0.009% - The commission banned lead-based paint in 1978
True/False: Dust sampling only done for hazard assessments - CORRECT
ANSWER -True; only risk assessors take samples to determine likelihood of
coming into contact with contaminants
What kind of sampling must be done for inspections? - CORRECT
ANSWER -Random ... repeats must be annotated then you move onto the next
HUD Guidelines for abatement - CORRECT ANSWER -Must last 20 years.
Includes the following procedures: - Removal - Enclosure - Replacement -
Encapsulation Painting over is a temporary fix!
Water standards for lead - CORRECT ANSWER -- 15 ppb under the Clean
Water Act (CWA) - 5 ppb under the FDA standard (bottled water) *These are
the ONLY instances where ppb is used
Why was lead used so much? - CORRECT ANSWER -- Durable - Colorful
- Anti-corrosive - Anti-fungal - Drying agent
What does RRP do? - CORRECT ANSWER -- Renovation, Repairing, and
Painting program - Provided enforcement to Title X in 2010 ... $37,500 fines for
violation - Dust sampling technicians can only sample for RRP projects
