Ecological diagnosis
and water quality.

Understanding what's affecting your lake or waterway. A rigorous diagnosis to identify the causes of a water quality issue and design an effective, tailored action plan.

Overview

A complete diagnosis, not just numbers, but causes and solutions.

An ecological diagnosis of a body of water establishes an overall picture of its health: physico-chemical water quality, watershed condition, human and natural pressures, and aquatic habitat quality. It's the essential tool for understanding why a lake or waterway is degrading, and for designing targeted, effective interventions.

Our team measures, in the field and in an accredited laboratory, the essential parameters needed to obtain an accurate picture of a body of water's trophic state. Results are put into context with the watershed analysis to identify pressure sources and prioritize the actions that will sustain the ecosystem over the long term.

What it includes

A complete picture of the body of water and its watershed.

  • Measurement of all the physico-chemical and biological parameters needed, in the field and in an accredited laboratory, to build a complete picture of the water body's health
  • Watershed analysis: land cover, diffuse and point pollution sources
  • Assessment of aquatic habitat quality (HQI) and targeted wildlife inventories
  • Diagnosis report with prioritized action plan and management recommendations
Sampling and water quality analysis at a lake
Our method

From sampling to protection strategy, a structured approach.

  1. Identification of potential issues

    Analysis of land use in the watershed based on photo-interpretation and available geomatic data. Inventory of potential sources of nutrients and contaminants, and documentation of diffuse inputs (runoff, septic systems, agricultural activities, urbanized areas, etc.).

  2. Work plan

    Development of a sampling plan tailored to the targeted issues: choice of parameters to measure, location of stations and scheduling of campaigns according to critical periods.

  3. Data collection

    Field campaigns: in situ measurements using calibrated equipment and samples analyzed by an accredited laboratory.

  4. Interpretation and diagnosis

    Correlating analytical results with field observations and the watershed portrait. Comparison with MELCCFP quality criteria, identification of the primary and secondary causes of the observed issues, and recommendations for protecting the body of water.
