Few can question the benefits attributed to the ecological approach when used to monitor and evaluate pollution impact and extent. The main benefits attributed to the ecological approach are the holistic approach it provides, the ability to determine long term impact of pollution (including temporal parameter) and its ability to track the effectiveness of remediation measures. Previous few years of implementation proved that the maximum benefit is gained when combining the outcome of ecological, biological and chemical monitoring at the same time. Chemical assessment can’t be neglected since different ecosystems may react differently to different sources of pollution. The major obstacle facing the biological approach is determining the baseline characteristics for biological communities for each type of water bodies.

These results were reached through, investigating the biological and chemical aspects of the ecosystem and the relationsh

Healthy waterbodies exhibit ecological integrity, representing a natural or undisturbed state.

Resident biota function as continual monitors of environmental quality, increasing the likelihood of detecting the effects of episodic events (e.g., spills, dumping, treatment plant malfunctions, nutrient enrichment), toxic nonpoint source pollution (e.g., agricultural pesticides), cumulative pollution (i.e., multiple impacts over time or continuous low-level stress), or other impacts that periodic chemical sampling is unlikely to detect.

Restoration is a broad term that encompasses a number of interrelated activities, including the reconstruction of antecedent physical conditions, chemical adjustment of the soil and water, and biological manipulation which includes the reintroduction of native flora and fauna.
