Sewage Effluent Testing

Joshtek Marine Provides Sewage Effluent Sampling Services to Identify and Mitigate Environmental Risks

Marine pollution caused by the substandard discharge of domestic sewage from ships has received considerable attention in recent years. 80 percent of the world trade depends on sea trade. A single cruise ship with 3,000 passengers and crew can generate between 55,000 and 110,000 Liters of untreated or inadequately treated sewage water per day. This Sewage water can contain harmful bacteria, viruses, parasites, and sewage nutrients that can cause fish kills, elevate algae blooms, and disrupt the aquatic ecosystem’s food chain.

What are the current regulations?

The USCG has adopted the IMO's MARPOL Annex IV standards. But the limits are more stringent if Ships that discharge sewage into US waters must comply with the VGP regulation.
