Pollution control philosophy with relation to Water Pollution
One aspect of environmental protection are mandatory regulations but they are only part of the solution. Other important tools in pollution control include environmental education, economic instruments, market forces and stricter enforcements.
Standards can be "precise" (for a defined quantifiable minimum or maximum value for a pollutant), or "imprecise" which would require the use of Best Available Technology (BAT) or Best Practicable Environmental Option (BPEO).
Market-based economic instruments for pollution control can include charges, subsidies, deposit or refund schemes, the creation of a market in pollution credits, and enforcement incentives.
Moving towards a holistic approach in chemical pollution control combines the following approaches: Integrated control measures, transboundary considerations, complementary and supplementary control measures, life-cycle considerations, the impacts of chemical mixtures. Control of water pollution requires appropriate infrastructure and management plans.
The infrastructure may include wastewater treatment plants, for example, sewage treatment plants and industrial wastewater treatment plants. Agricultural wastewater treatment for farms and erosion control at construction sites can also help prevent water pollution.
Effective control of urban runoff includes reducing speed and quantity of flow. Water pollution requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells).
