1. An apparatus to monitor halohydrocarbon presence in a water distribution system, the apparatus comprising:
circuitry to communicate with a network;
a sample extraction mechanism to from-time-to-time draw water samples from the water distribution system;
a reservoir for a standard;
a measurement system to obtain measurements of halohydrocarbon concentration in respective ones of the water samples;
an electronic control system to
control the sample extraction mechanism and the measurement system so as obtain the measurements,
control the apparatus so as to from-time-to-time perform calibrations using the standard, and
renew the measurement system for ensuing ones of the measurements;
wherein the electronic control system is to control the apparatus to obtain the measurements according to timing that is externally dictated via the network.
