Can contaminated groundwater be cleaned up?
Yes, but it can be time-consuming and expensive. Communities whose drinking water source has become contaminated have had to spend millions of dollars to remove contaminants from the water before it can be piped to homes and businesses. The cleanup is effective, but it can significantly affect the cost of providing the water to customers. It is far better to prevent contamination in the first place. What are the dos and do nots for groundwater?


  • Purchase only what you need

  • Use products completely before disposing

  • Recycle whatever you can (oil, batteries, etc.)

  • Recycle surplus paints

Do not:

  • Dump products onto the ground (they can contaminate soil and groundwater)

  • Pour products or wastes into the street (they can contaminate oceans, lakes, and groundwater)

  • Put hazardous or toxic products in the trash

  • Pour products down the drain
