Hammond water quality

Northshore · Tangipahoa Parish Water District / City of Hammond · PWS ID LA1105008 · Southern Hills aquifer (groundwater)

The short answer

Hammond water is soft, chloramine-disinfected aquifer groundwater. The fix: a whole-home catalytic carbon filter plus reverse osmosis for drinking water.

Most Hammond addresses are served by the Tangipahoa Parish Water District, with the rest on the City of Hammond system. Both are soft aquifer water disinfected with chloramine. We confirm which one serves your address, then match the system to it.

Here is your system: whole-home catalytic carbon for the chloramine at every tap, plus reverse osmosis at the kitchen sink for the water you drink and cook with. It is the setup we put in most Hammond homes, and it earns its keep every single day.

Easier on the parts that wear out

Sediment settles in your water heater and lowers its efficiency, and chlorine and chloramine embrittle the rubber seals, gaskets, and hoses inside your appliances over time. Filtering the whole house is gentler on all of it.

The public recordInventory-deadline paperwork only

EPA shows a Lead and Copper Rule item for the Tangipahoa Parish Water District dated October 2024. This was the federal service-line inventory reporting deadline that thousands of systems nationwide missed. It is a reporting deadline, not lead found in the water, and it was resolved. State surveys have flagged finished-water-storage deficiencies, which are findings, not violations.
