SGS Expands Marine Services as Cruise Industry Growth Raises Onboard Environmental Concerns

# What SGS is doing for cruise ships SGS, a Geneva-based testing, inspection and certification company founded in 1878, has broadened its marine services to meet growing environmental health needs on cruise ships. The company began moving into the cruise sector around 2000 and now works with approximately 85% of the world's cruise lines.

# Why the work matters now

# Services SGS provides SGS's marine services cover a practical range of environmental and public health checks:

• Water testing for ballast systems and onboard treatment plants. These tests are tied to regulatory programs such as the EPA's general vessel permit.
• Legionella testing. SGS has expanded this capability with global labs certified by the U.S. Centers for Disease Control (CDC). Legionella can grow in closed water systems and become airborne via showers, cooling units, and whirlpools.
• Air and mold sampling in passenger and crew cabins and public spaces.
• Noise, temperature, and other environmental exposure measurements for crew and passengers.
• Shore-side water testing at private islands for bacteria and fecal contamination where guests swim.
• Crew wellbeing surveys that include interviews and observations about living and working conditions.

SGS technicians reportedly evaluate about 20 discrete items during ship visits, combining instrument measures with observational checks and interviews.

# Examples of onboard hazards SGS encounters SGS highlights straightforward, avoidable problems that can affect health. One cited example is painting in food-service areas when paint is still wet. Volatile fumes can settle on food surfaces and become an ingestion exposure pathway. Another recurring risk is Legionella in showerheads and cooling systems.

# How regulation fits in

# Practical implications for cruise lines and travelers For cruise operators: routine, documented environmental testing and crew wellbeing assessments can reduce exposure risks, help meet evolving regulations, and flag operational issues such as unsafe maintenance practices.

For travelers: improvements in testing and monitoring mean better detection of hazards like Legionella, contaminated shore waters, or airborne chemical exposure, but the degree of protection can vary by line and by specific ship practices.

# Bottom line SGS has scaled its marine testing and inspection footprint as the cruise industry grows, emphasizing concrete checks — water, air, noise, and crew wellbeing — that address real onboard exposure risks and link to changing regulatory expectations.
