Environmental Considerations
Andover’s climate influences local environmental initiatives. The city participates in the National Pollutant Discharge Elimination System (NPDES) Phase II Program to maintain the health of lakes, rivers, streams, and wetlands. This program addresses challenges such as increased urban development, which can lead to soil erosion and higher runoff into water bodies. Residents are encouraged to adopt practices like minimizing exposed soils, planting native vegetation, and properly disposing of waste to support these efforts.
Additionally, the Minnesota Pollution Control Agency (MPCA) has been monitoring groundwater contamination in the Eastbrook Terrace area of Andover. Contaminants like 1,4-dioxane and per- and polyfluoroalkyl substances (PFAS) have been detected in some private wells. The MPCA is providing bottled water to affected homes and continues to investigate the contamination sources to ensure safe drinking water for residents.
Understanding Andover’s climate and participating in environmental stewardship can enhance the quality of life for all community members. Staying informed about seasonal changes and local environmental issues empowers residents to make proactive decisions throughout the year.
