We receive our drinking water from either groundwater or surface water sources. Both groundwater and surface water are constantly moving. Therefore, contamination that occurs outside of your community could eventually reach your tap.
Here are some ideas:
The maps below are examples taken from the SWA online database. They exemplify why cooperation with your neighbors in paramount to source water protection!
The map above is taken from DEQ’s online SWA database for the City of Shoshone. It shows the direction and time-of-travel zones for groundwater being captured by Shoshone’s wells. As the map shows, drinking water for the City of Shoshone first passes under the City of Richfield. If there were any pollution occurring in Richfield, it could eventually reach the intake for Shoshone’s wells.
The map shown above, is from the SWA online database for the City of Teton. Similar to the map for Shoshone, it shows that Teton’s drinking water passes under the City of Newdale.
