Most local water municipal post reports online. These results do not reflect the water quality directly from your faucet but as it leaves the water treatment center.
They give results in common units. For instance, they can give you a number like 3.5 – 7.0 meaning moderate hard. To learn how to interpret the units
Soft: 0-3.5 grains per gallon (gpg),
moderate: 3.5-7.0 gpg,
hard: 7.0-10.5 gpg, and
very hard: over 10.5 gpg

Fill your clean bottle one-third full and add few drops of liquid soap close the bottle and shake for few seconds. If there are no bubbles and water appears milky/ fluffy then your water is hard.
