1. A method for detecting, isolating, and flushing contaminated water in a municipal water supply system utilizing a single device, the method comprising: receiving, by a communications subsystem, test data of water flowing through a node in the municipal water supply system;determining whether the water is contaminated based at least in part on the test data;sending, by the communications subsystem, a first signal to a communication facility if the water is contaminated;isolating, by an isolation subsystem, the contaminated water by receiving, by the communications subsystem, a second signal including instructions to shut a valve disposed at least one of upstream and downstream from the node if the water is contaminated; andopening a flushing valve of a flushing subsystem to divert the contaminated water out of the water supply system by activating a flushing device with a controller, the flushing device configured to open and close the flushing valve,wherein the single device comprises a casing, the flushing subsystem, the communications subsystem, and the isolation subsystem, wherein the casing is coupled to the single device and houses the controller and the communications subsystem. 2. The method of claim 1, wherein the step of determining whether the water is contaminated comprises determining whether the water has at least one of a chemical contaminant, a microbial contaminant, and a radiological contaminant. 3. The method of claim 1 wherein the communication facility is a monitoring facility. 4. The method of claim 1 further comprising receiving a response signal to open the flushing valve if the water is contaminated. 5. The method of claim 1, wherein the single device is a hydrant. 6. A system for detecting and flushing contaminated water in a municipal water supply system comprising: at least one device connected to the municipal water supply system;at least one monitoring and detection subsystem connected to the municipal water supply system to detect contaminated water;at least one communications subsystem connected to the at least one monitoring and detection subsystem;at least one flushing subsystem connected to the municipal water supply system, the at least one flushing subsystem comprising a flushing valve and a flushing device configured to open and close the flushing valve, the at least one flushing subsystem responsive to instructions received from the communications subsystem to a controller to flush the contaminated water from the municipal water supply system by activating the flushing device to open the flushing valve; andat least one valve connected to the municipal water supply system,wherein the at least one device comprises a casing, the at least one flushing subsystem, and the at least one communications subsystem, wherein the casing is coupled to the at least one device and houses the controller and the at least one communications subsystem. 7. The system of claim 6 wherein the at least one valve is closed when a contaminant is detected. 8. The system of claim 6 wherein the at least one monitoring and detection subsystem comprises a chemical contaminant detector. 9. The system of claim 6 wherein the at least one monitoring and detection subsystem comprises a microbial detector. 10. The system of claim 6 wherein the at least one monitoring and detection subsystem comprises a radiological detector. 11. The system of claim 6 wherein the at least one device is a hydrant. 12. The system of claim 6 wherein the communications subsystem comprises a wireless transmitter and receiver. 13. The method of claim 1, further comprising determining whether a contaminant contaminating the water is flushable if the water is contaminated. 14. The method of claim 13, further comprising isolating the contaminant in the municipal water supply system if the contaminant is not flushable. 15. The method of claim 13, further comprising flushing the contaminant from the municipal water supply system if the contaminant is flushable. 16. The method of claim 1, wherein the municipal water supply system comprises a monitoring and detection subsystem. 17. The method of claim 16, wherein the monitoring and detection subsystem comprises a chemical contaminant detector. 18. The method of claim 16, wherein the monitoring and detection subsystem comprises a microbial detector. 19. The method of claim 1, wherein the first signal and the second signal comprises a wireless signal. 20. The method of claim 1, wherein the flushing device is an electric motor, and the flushing subsystem comprises the electric motor and a flushing diffuser.
