Sometimes water gathers in depressions where soils drain poorly, these depressions range from puddles to lakes. Surface water is a major source of drinking water for the coastal edges of Michigan. Layers of sediment or bedrock completely saturated with water are called aquifers . The place where the aquifer begins is called the water table. These aquifers are a source of groundwater, which is in turn pumped out of the soil or bedrock, via a well, for human consumption.
Water returns to the atmosphere through evapotranspiration .
The water then condenses, falls as precipitation and restarts the entire process. There are countless activities homeowners can do to protect their drinking supply. This includes composting organic materials and taking other products to recycling centers. Recycling means less water used, so contaminants are less likely to be drawn to wells. Native plants are adapted to Michigan's climate and its pests, so there is a minimal need for water, fertilizer and pesticide applications.
