Abstract: An example system for bacteria, algae and/or bacteria detection is provided. The system includes a database configured to electronically store data. The data includes a detection model trained based on historical bacteria, algae and/or cyanobacteria identification and cell count data. The system includes a processing device in communication with the database. The processing device is configured to receive as input an electronic image of a water sample, electronically detect bacteria, algae and/or cyanobacteria in the electronic image, execute the detection model to identify an organism responsible for the detected bacteria, algae and/or cyanobacteria, and estimate a cell count of the responsible organism based on the electronic image.
