Study Notes
Lesson 6: Monitoring and Measurement
- Monitoring and measurement are systematic processes that observe, track, and quantify environmental aspects to assess performance and compliance. A good example is monitoring air emissions from a manufacturing facility to ensure adherence to regulations.
- Learning objectives include understanding the importance of monitoring and measurement, developing effective monitoring programs, and collecting and analyzing environmental performance data.
- Monitoring programs are structured plans that systematically observe and assess environmental aspects of an organization. An example is designing a program to track water usage and discharge in a wastewater treatment plant.
- Data collection methods include direct measurements like the use of specialized instruments to measure parameters such as air quality, noise levels, or water quality. Automated meters and sensors can also be used for continuous monitoring.
- Examples include air quality meters, noise level meters, water quality meters, flow meters, temperature sensors, and humidity sensors.
- Sampling methods include grab sampling (collecting samples at specific points in time), composite sampling (combining multiple samples over a period), and passive sampling (using devices to accumulate pollutants over time).
- Passive samplers can measure air or water pollutants.
- Scientists can use them to study pollutants like volatile organic compounds (VOCs).
- Technological solutions include remote sensing (using satellite or aerial-based technologies to collect data over large areas) and geographic information systems (GIS) (integrating spatial data to analyze and visualize environmental information).
- Data logging is using electronic devices to record environmental data at regular intervals. Data loggers can record temperature, humidity, and energy consumption.
- Environmental monitoring networks deploy networks of sensors and monitoring stations to collect real-time data across multiple locations (e.g., air quality monitoring in urban areas).
- Documentation review involves examining permits, incident reports, and other documentation to assess historical environmental performance.
- Performance indicators and key performance indicators (KPIs) define specific metrics to measure and monitor environmental performance. Examples include energy consumption, greenhouse gas emissions, waste generation, and water usage.
- Interviews and stakeholder engagement involves conducting dialogue with employees, stakeholders, or community members to gather qualitative insights (e.g. perceptions of environmental aspects).
- Surveys and questionnaires gather information on environmental awareness, attitudes, and behavior (e.g., surveys on employee knowledge of environmental policies).
- Data analysis and reporting involve the systematic examination of environmental performance data to identify patterns and trends, and to communicate findings to stakeholders. Key approaches include statistical analysis, trend analysis, and comparative analysis.
- Comparative analysis looks at environmental performance over time, between locations and/or between organizations to understand best practices (e.g. benchmarking water usage for a business).
