Science in the Parks: Filtering Water

filtering water 4Filtered water is an important part of the water system here in Berkshire County. The water we drink comes from a water treatment plant that first filters our water for big bulky things like leaves, branches and live animals such as fish and frogs. This is a filter with big holes. Next the water is filtered through a finer medium like sand and finally it is filtered through an even finer medium to remove even smaller particles.
