- County estimate
Water samples from around Bossier City put hardness at about 48 mg/L (2.8 gpg), which would be soft on the USGS scale. Treat this as a rough guide: it is the median of 663 samples taken across Bossier Parish, mostly wells and streams, not a test of Bossier City's treated tap water. One more reason for caution: EPA lists Bossier City's water system as using surface water, which is often softer than the wells behind the county figure.
At 48 mg/L, Bossier City is 54 mg/L below the typical Louisiana figure of 102. Of the 10 nearest cities we track, 3 have softer water and 7 have harder. The range nearby runs from 20 mg/L in Ruston to 211 in Sulphur.
What 48 mg/L means at home
Soap and shampoo lather with very little product. Kettles and showerheads stay mostly free of white crust.
Some people notice that soap feels slow to rinse off in soft water. That slippery feel is normal and harmless.
Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.
What to do about it
Nothing, as far as hardness goes. At 48 mg/L a softener would have almost nothing to remove.
Carbon filter
If the water tastes of chlorine, a pitcher or faucet carbon filter takes care of that. It does not change hardness.
