Evaluation of a Predictive Water Quality Model

Evaluation of a Predictive Water Quality Model

Identifying times when water is unsafe for recreation, for drinking, or for aquatic life is a major challenge. Traditionally, sampling has been the preferred means of determining whether water is safe. Predictive modeling based on artificial intelligence (AI) is an approach that is becoming more and more popular.

Combined Sewer Overflows in Quebec

Combined Sewer Overflows in Quebec

In October 2015, during the now famous Flushgate, the city of Montreal discharged eight billion liters of wastewater into the St. Lawrence River in order to carry out repairs on the sewer system. Through this article, I intend to provide answers to several questions concerning overflows, such as: “What are overflows?” and “What is their real impact on waterways in Quebec?”

Data Science: 6 Common Data Types

Data Science: 6 Common Data Types

Before any project, it is crucial to understand the difference between the following data types: numerical, categorical, continuous, discrete, nominal and ordinal. This knowledge is key to fully grasp the statistical nature of the available data and to properly handle any given features. Despite its simplicity, this step is essential to achieve a robust and meaningful data analysis. In fact, data types usually dictate which imputation strategies, statistical measurements, plot designs and algorithms are the most appropriate to use.

Explaining the Rise of AI in Our Lives

Explaining the Rise of AI in Our Lives

The rise of Artificial Intelligence (AI) in recent years has become quite apparent and has reached our daily lives. Today, in 2020, we are surrounded by AI applications. It’s present in our web browsers, our social media platforms, our cell phone cameras and it’s even found in our cars.

Water Quality, a Matter of Perspective.

Water Quality, a Matter of Perspective.

We often tend to forget that the idea of “good” water is a matter of perspective. Lakes and rivers are used for a variety of functions such as drinking water, swimming, irrigation and therefore each person’s perspective of “good” water quality comes from how they use it. When assessing the health of a waterway, we need to be able to evaluate these different perspectives as a whole, but not much is known about how these perspectives overlap in terms of safety standards.

Exploring Pathogens In Recreational Waters

Exploring Pathogens In Recreational Waters

As a result of modern water treatment and sanitation methods in developed countries, exposure to pathogens transmitted through contaminated drinking water is uncommon. Through this blog post, I intend to explore the world of pathogens present in recreational waters in greater detail.
