Pulp Mill Wastewater Loads: More about the data

Alberta's seven pulp mills submit monthly monitoring data that is entered into Alberta Environment's Environmental Management System database. The average pulp production per day and the average amount of biochemical oxygen demand released per day (in kilograms) is calculated for each of the seven pulp mills for a given year. The average of all seven mills is added to provide the total pulp produced per day for all mills. The total average of the biochemical oxygen demand released per day (in kilograms) for all mills is also added together.
