### >> Reducing the volume of hazardous substances discharged into water



 

 

 



**OUR CLIENT'S CHALLENGE -** Wastewater disposal zones can release significant amounts of micro-pollutants into aquatic environments. Laws aiming to reduce the amounts of these substances discharged, lost and emitted have been reinforced, and the project manager must be familiar with and consider such emissions within their assigned area. Several local councils contacted Veolia and its engineering office OFIS to meet regulations on monitoring hazardous substances discharged into water (RSDE).

**OFIS' SOLUTION -** OFIS can provide its clients with documented research results on pollutant emissions achieved using a methodical and disciplined approach, involving:

- Identifying and mapping potential sources of significant volumes of pollutants upstream from treatment plants;
- Proposing a sampling strategy to confirm any assumptions;
- Drafting a council-level action plan to reduce these emissions.
