A natural water treatment choice
Active treatment solutions often require large quantities of equipment, chemicals and electricity to manage condition variability and achieve the required discharge quality.
Semi-passive and passive treatment solutions can take longer to implement but can result in lower overall cost by applying natural processes to remove certain constituents such as ammonia and selenium. They are also designed with site closure in mind.
Working on the leading edge of biochemistry and geosciences has enabled us to successfully implement passive water treatment systems. Start leveraging our experience today:
Passive & Semi-Passive Water Treatment
Any form of passive water treatment requires a site-specific water management plan that accounts for the ambient water quality, mine life cycle, stability of treated constituents, constructible land area, climate, material availability, and geological makeup.
By evaluating these data points, we build the scientific case for the performance treatment system, be that Gravel Beds Bioreactors (GBR), constructed wetlands, Saturated Rock Fill (SRF), or other in-situ treatment.
Critically, our processes combine field investigations, laboratory column trials, and technical desktop reviews to reduce in-field testing costs. Below are just some of the studies and regulatory assessments we can assist with to better understand your mine waters:
Assessment and Feasibility Services
- Aqueous Chemical Modelling
- Laboratory scale climate-controlled testing
- Stress-testing conditions simulation
- Remote monitoring units
- Hydrology and hydrogeological evaluations
- Water resource and Aquatic habitat assessments
- Regulatory applications & consultation
- Technology Selection
Passive Water Treatment Best Practices
Passive water treatment is vastly more effective with water containment prevention, and decentralized treatment – i.e., treatment as close to the source as possible.
Minimizing interaction between types of mine water de-risks your project by applying the most cost-effective in-situ approach to each development plan phase.
Managing Risk and Accountability
- Diversion Structures and Contouring
- Natural variable evaluations (climate, flow, etc.)
- Covers & revegetation
- Redox Buffering
- Water Resource Infrastructure
- Treatment Train Evaluation
- Water Transportation
- Drilling and injection well testing
- Water Repurposing
Maintaining Treatment Compliance
Experience with the permitting process is key to any water treatment project’s success. Without working knowledge of discharge criteria, and the impact on the receiving environment, you may be unnecessarily committed to expensive treatment limits.
Working with us will not only expose you to our experience working with regulators to negotiate discharge limits and navigate permitting processes; but will also provide you with the water monitoring services required to monitor and maintain compliance.
Monitoring & Support Services
- Tracer tests
- Aqueous chemistry modelling
- Geomatics support
- Hydrological and hydrogeological evaluations
- Personnel training
- Remote monitoring program software

- Emissions tracking & ESG reporting
ESG Support Services
Now more than ever, environmental, social, and governance (ESG) risks and opportunities must be considered at an early stage in project development. Several jurisdictions have already mandated climate disclosure, and it is anticipated to come into effect in Canada and the United States as early as 2023.
There also continues to be momentum in standardized global sustainability reporting that will have an impact on all industries. We are proactively monitoring the regulatory and reporting landscape so that your company provides ESG reporting that is comprehensive and accurate while ensuring it meets the most current regulations and standards.
We offer a comprehensive range of ESG services in support of your regulatory journey.
- ESG materiality assessments & benchmarking
- Climate change consulting
- ESG reporting & compliance
- Insurance, financing, and carbon credits
- Social inclusivity studies
- Opportunities in the energy transition
- Corporate governance advisory
