Freshwater and bilge water testing are two important procedures in the marine industry.

Freshwater testing is conducted to ensure that the water used for various onboard applications, such as drinking, cooking, cleaning, and bathing, meets the required quality standards. The testing involves analyzing the water samples for various parameters, such as pH, total dissolved solids (TDS), total suspended solids (TSS), chlorine residual, and bacterial contamination. The results of the testing are used to determine whether the water is safe for use or needs treatment.

Bilge water testing, on the other hand, is conducted to ensure that the water in the bilge, which is the lowest part of the vessel’s hull, is free from contaminants such as oil and grease. The testing involves analyzing the water samples for various parameters, such as oil content, pH, and conductivity. If the bilge water contains excessive oil or other contaminants, it must be treated or disposed of in accordance with applicable regulations.

Both freshwater and bilge water testing are important for maintaining the safety and efficiency of marine operations. Freshwater testing helps ensure that the crew and passengers have access to safe and clean water, while bilge water testing helps prevent pollution of the marine environment. Regular testing of both freshwater and bilge water can also help detect any issues early, allowing for prompt corrective action and preventing more significant problems from developing.
