Bangkok: The Pollution Control Department (PCD) has initiated an investigation into the recent oil spill on Rama III by analyzing "oil fingerprints" to ascertain the source of the leak. Officers were dispatched to the site to ensure safety and collect samples after a reported leak in the oil pipeline in Khlong Toei District.
According to Thai News Agency, Dr. Surin Worakitthamrong, Director-General of the PCD, explained that officers were sent to measure volatile organic compounds (VOCs) and Leakage Limit (LEL) levels in the area. These measurements aim to assess the risk and provide necessary warnings to the public if harmful levels are detected.
The PCD plans to collect and compare oil samples from the recent leak site with those previously found in the drainage system. The Petroleum Institute of Thailand will assist in examining these "oil fingerprints" to determine if the samples match and originate from the same source.
Dr. Surin emphasized that further investigation is required to confirm whether the recent leak is the source of the spill. Initial observations suggest that the most recently found oil appears old, whereas the oil initially discovered in the drainage system did not seem as aged, necessitating the fingerprint comparison to accurately identify the source.
The PCD has been continuously monitoring the situation, measuring VOCs and LEL levels in the drainage system and collecting oil samples to determine their type and source. On September 9, the highest VOC level recorded was 626 ppm, which decreased to 153 ppm by September 10, indicating a significant reduction in potential risk.
