Patent ID: 7424399

Claim:
A method of monitoring fluid quality, comprising the steps of: receiving, by a computer system controlled by a service provider, first fluid test data generated by a first sensor unit controlled by first entity, wherein the first sensor unit is configured to establish communication with the computer system via one or more communication networks, and wherein the first fluid test data includes first location information identifying where the first fluid test data was taken, storing the first fluid test data, receiving, by the computer system controlled by the service provider, second fluid test data generated under the control a second entity different from the first entity, wherein the second fluid test data includes second location information identifying where the second fluid test data was taken, storing the second fluid test data permitting a first user authorized by the first entity to access aspects of the first fluid test data from the computer system controlled by the service provider via the Internet using a graphical computer interface at a first computer operated by the first user, and permitting a second user authorized by the second entity to access aspects of the second fluid test data from the computer system controlled by the service provider via the Internet using a graphical computer interface at a second computer operated by the second user, wherein permitting the access to the first user allows the first user to visualize first information associated with the first fluid test data overlaid on a geographical map displayed on the graphical computer interface of the first computer, and wherein permitting access to the second user allows the second user to visualize second information associated with the second fluid test data overlaid on a geographical map displayed on the graphical computer interface of the second computer.
