What’s really in your Longboat Key water
Here’s the honest breakdown of the water reaching most Longboat Key homes — and what it means for the system you actually need.
- Provider: Manatee County Utilities (which serves the whole key, both county sides)
- Source: Lake Manatee (surface water)
- Hardness: about 8 grains per gallon — moderately hard; enough to scale fixtures and dull soap
- Disinfection: chloramine (chlorine + ammonia)
- PFAS: Manatee County tested all 29 PFAS in its 2024 UCMR5 round — every one came back below the lab’s reporting level
- Chloramine needs more contact time than plain chlorine — so catalytic carbon is the right filter, not the mixed-bed carbon most companies install.
- Hardness is handled by a properly sized water softener.
- Dissolved solids and taste are polished by reverse osmosis at the drinking tap.
The honest part: published averages are a starting point, not your actual tap — so we test your water free, on-site, before recommending anything.
