Drinking Water - Compliance Monitoring

Compliance monitoring involves the collection of water samples from public drinking water systems to insure compliance with all State and Federal Regulations. This monitoring is based upon the type, size and water source of the public water system.

A public water system is defined as (1) any public or privately owned waterworks system which provides drinking water, whether bottled or piped, for human consumption, including the source of supply whether the source of supply is of surface or subsurface origin. (2) All structures and appurtenances used for collection, treatment, storage or distribution of drinking water delivered to customers.  (3) Any part or portion of the system and including any water treatment facility which in any way alters the physical, chemical, radiological, or bacteriological characteristics of drinking water; provided that public water system shall not include a drinking water system serving a single private residence or dwelling.  A separately owned system with its source of supply from another waterworks system shall be a separate public water system.

Listed below are the four types of Public Water Systems.
