Source Water Protection
Source water is untreated water from streams, rivers, lakes or underground aquifers that is used to provide public drinking water, as well as to supply private wells used for human consumption. Some water treatment is usually necessary, so public utilities treat most of the drinking water before it enters the home. However, the cost of this treatment, as well as the risks to public health, can be reduced by protecting source water from contamination.1 The idea of preventing contamination from entering the source water before it is treated is known as 'Source Water Protection'. The protection of our source water is not only important to maintain a clean supply for human consumption, but to ensure that our environment is healthy for all uses of water.

Source Water Protection ResourcesPlanning Tools
A wide variety of technical and managerial source water protection practices are available for use, including management practices for point and nonpoint pollution sources; stormwater management; wastewater treatment plant upgrades and maintenance; rules and assistance for maintaining septic systems; agricultural management practices, incentives, and land stewardship programs; erosion and sediment control for construction projects; land-use controls; source water monitoring (including early warning monitoring and chemical and microbial pollutant source tracking); and watershed protection, management, and stewardship programs.
In order for a water utility to implement source water protection practices they must have a plan in place. The following two planning tools will help guide a utility in their decision making processes.
Source Water AssessmentPurpose
The objective of a source water assessment is to identify point-sources and non-point-sources of potential contamination to drinking water source(s). For example, a point-source may be a business' discharge pipe or a septic system. Examples of non-point-sources may be chemically treated agricultural land or disturbed land on a construction site.Review and revision
A source water assessment addendum must be provided for each new water source added to the system.
Source Water/Wellhead Protection PlanPurpose
Virtually every stream, lake, river and aquifer in the United States is used as (or is connected to) a drinking water source. Protecting these source waters from contaminants is a major national priority in protecting public health through ensuring a clean, safe drinking water supply. The source water protection plan will respond to the priorities identified in the source water assessment (see above).Considerations
Writing the plan will normally require a project team including representatives from not only the water system, but also agricultural/commercial/industrial/development businesses, any local/state/federal/tribal entities with authority to make regulatory or land use decisions in the source water protection areas, other water providers, conservation/environmental/watershed groups, teachers, and citizens.Review & revision
A source water protection plan addendum must be provided for each new water source added to the system. Otherwise, source water protection plans and implementation should be reviewed annually, but no less than once every five years.
