,Section A - Water Quality AND Protection
Q1.
A beach monitoring program in Hawaii reports enterococcus levels of 130 CFU/100 mL.
According to the EPA's 2012 Recreational Water Quality Criteria, what is the correct
management action for this designated beach area?
A. No action required; enterococcus is not a B. Issue a beach advisory because the
primary indicator. geometric mean exceeds the 30-day
threshold of 30 CFU/100 mL.
C. Close the beach immediately because D. Conduct a sanitary survey to identify
the single-sample maximum of 110 pollution sources before any advisory.
CFU/100 mL is exceeded.
Correct: C - Close the beach immediately because the single-sample maximum of 110
CFU/100 mL is exceeded.
Rationale:The EPA's 2012 RWQC sets a single-sample maximum for enterococcus of 110
CFU/100 mL for marine waters. A level of 130 CFU/100 mL exceeds this, warranting
immediate beach closure or advisory. Option A is false; enterococcus is the primary indicator.
Option B is incorrect because the geometric mean applies to multiple samples over 30 days.
Option D is a secondary step after the advisory.
Q2.
During an inspection of a food establishment, a health specialist observes that raw
chicken is stored above ready-to-eat lettuce in a walk-in cooler. Which food safety
principle is being violated?
A. Time-temperature abuse B. Cross-contamination
C. Poor personal hygiene D. Improper cooling
Correct: B - Cross-contamination
Rationale:Storing raw chicken above ready-to-eat foods allows juices to drip onto the lettuce,
causing cross-contamination. Time-temperature abuse (A) refers to improper temperature
control. Poor personal hygiene (C) involves handwashing or glove use. Improper cooling (D)
relates to rapid temperature reduction after cooking.
Q3.
A community near a former sugarcane plantation reports high rates of birth defects.
Groundwater tests show elevated levels of a persistent organic pollutant. Which chemical
is most likely responsible?
Page 3
, Section A - Water Quality AND Protection
A. Atrazine B. Heptachlor epoxide
C. Arsenic D. Glyphosate
Correct: B - Heptachlor epoxide
Rationale:Heptachlor epoxide is a persistent organic pollutant and a metabolite of heptachlor,
historically used in sugarcane farming in Hawaii. It is known to bioaccumulate and cause
developmental toxicity. Atrazine (A) is a herbicide but less persistent in groundwater in
Hawaii. Arsenic (C) is naturally occurring but not specifically linked to sugarcane. Glyphosate
(D) degrades more rapidly.
Q4.
Which of the following best describes the primary mode of action of malathion when used
in adulticiding for mosquito control in Hawaii?
A. Inhibition of acetylcholinesterase, leading B. Disruption of the insect cuticle synthesis
to neurotoxicity
C. Activation of sodium channels causing D. Blockade of GABA receptors causing
repetitive nerve firing hyperexcitation
Correct: A - Inhibition of acetylcholinesterase, leading to neurotoxicity
Rationale:Malathion is an organophosphate insecticide that inhibits acetylcholinesterase,
causing accumulation of acetylcholine and neurotoxicity. Option B describes insect growth
regulators. Option C describes pyrethroids. Option D describes organochlorines like lindane.
Q5.
A health specialist is evaluating a landfill site in a volcanic region of Hawaii. Which factor
poses the greatest risk for groundwater contamination from leachate?
A. Low annual rainfall B. High clay content in soil
C. Presence of permeable basalt rock D. Deep water table
Correct: C - Presence of permeable basalt rock
Rationale:Permeable basalt rock, common in Hawaii, allows rapid infiltration of leachate into
groundwater. Low rainfall (A) reduces leachate generation, not risk. High clay (B) impedes
infiltration. Deep water table (D) provides more soil filtration, reducing risk.
Q6.
An outbreak of hepatitis A is traced to a food handler at a restaurant. The handler is
asymptomatic but tests positive for IgM anti-HAV. Which period of infectivity is most
relevant for contact tracing?
