Students will state and describe the steps of the water treatment process that must occur before water can be safely used by community residents. Students will compare and contrast the water treatment guidelines used in different water treatment plants. (Some water treatment plants are less stringent on regulations than others). Students will question the practices of their own community water treatment plant with regards to safe water treatment.
Groundwater 1. How deep down is the water intake? If it is a shallow well (less than 30 m or 100 feet) then chances are that the quality of water is very different from a deep well (can sometimes be more than 100 m deep). The water from a shallow well can often have low levels of salt and other contaminants.
