| Area | Key Points |
|---|---|
| Monitoring | Oil pollution monitoring uses measurements from water, soil, sediment, and other environmental media. |
| Organic Indicators | BOD, COD, TOC, oil and grease, and UV absorption provide different measures of organic contamination. |
| Petroleum Indicators | Total petroleum hydrocarbons help estimate petroleum contamination and guide remediation planning. |
| Additional Indicators | Metals and radioactive compounds may require investigation where petroleum-related wastes create additional contamination concerns. |
| Prevention | Maintenance, training, cleaner technology, risk assessment, regulation, surveillance, and emergency planning help prevent spills. |
| Remediation | Dispersants, skimmers, sorbents, microbial degradation, and controlled burning can assist oil spill response under suitable conditions. |
| Management | Continuous monitoring verifies pollution extent, supports treatment decisions, and evaluates remediation effectiveness. |
