    The Water Hardness Directory is a community that allows any user to enter values for any city in the directory. Nothing but a user account is needed. The system is practically self-monitoring, since anyone can transmit a value and the average degree of hardness is determined from all values. Nevertheless, all information is not guaranteed and should be checked in case of doubt.
