rocks that have empty space
rocks that are tough and brittle
rocks that do not allow water to pass through them
rocks made up of granite
How can aquifers become polluted?
chemicals seeping through the porous rocks
oil running in with water
runoff from streets containing pollutants infiltrating the aquifer
all of these
Farmers use pesticides, herbicides, and fertilizers on their crops to enhance their yield. During a hard rain these chemicals can run off and chemically pollute the water.
