Hammond city core water, explained

The short answer

Hammond city core water is chloramine-disinfected groundwater. The recommendation for this water: a whole-home catalytic carbon filter plus optional reverse osmosis at the kitchen sink.

Chloramine is easier to miss than chlorine because its smell is less obvious. Hammond city core water carries chloramine at 1.8 parts per million. For perspective, chloramine in drinking water typically runs from 0.5 to 2 parts per million. At 1.8 parts per million, this system is near the high end of that range. Unless a pitcher or refrigerator filter specifically lists chloramine reduction, do not assume it removes it.

Chloramine is easier to miss than chlorine because its smell is less obvious. 8 parts per million.

What you may notice in your waterBeneath the surfaceWhat gets your attention?
Why it is easy to miss

Chloramine can be present without a strong smell

The report confirms chloramine in this water even if you do not notice the obvious pool smell associated with chlorine. Ordinary pitcher and refrigerator filters should not be assumed to reduce it unless chloramine is specifically listed.

  • Skin that feels tight or dry afterward
  • Hair that feels dry or harder to manage

What this report does not rule out

PFAS cannot be seen, smelled, or tastedPFAS are a large family of long-lasting manufactured chemicals. They are often called “forever chemicals” because they break down very slowly.

This report does not include a usable PFAS result. No result is not the same as no PFAS. Certified kitchen reverse osmosis reduces PFOA and PFOS in the water used for drinking and cooking.

chloramine at 1.8 ppm, near the high end of the typical 0.5 to 2 ppm range · Made to last longer and often less noticeable than chlorineCatalytic carbon removes it throughout the house
Chloramine is made by combining chlorine with ammonia. It lasts longer than chlorine and can be much less obvious at the tap. These numbers come straight from your water utility's published report.
What we'd install

Based on the report, whole-home catalytic carbon for the chloramine at every tap. Add reverse osmosis at the kitchen sink if better drinking water is part of why you're calling. If it isn't, the catalytic-carbon system remains the whole-house recommendation, and RO stays off the quote.

What this does for your home
  • Reduces chloramine throughout the house, including showers and the water used for coffee, tea, and cooking
  • Filtered drinking water from its own kitchen faucet
Cutaway of a water heater with sediment settled at the bottom
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.

What this means at your house

Your water arrives with chloramine in it, at 1.8 parts per million. Utilities make chloramine by combining chlorine with ammonia so it remains effective farther through the distribution system. It can be less obvious than chlorine: some people notice a faint chemical taste or odor, while others notice nothing at all. Ordinary pitcher and refrigerator filters should not be assumed to reduce it unless chloramine is specifically listed. Catalytic carbon reduces it before the water reaches the house.

The water here is groundwater, pumped from the aquifer under your feet.

How the report becomes the recommendation

It cannot say what is causing dry skin at your house. Hot water, soap, weather, and the disinfectant can all contribute, and the report only establishes that the disinfectant is present.

It publishes no hardness figure, so any softener conversation starts with a test at your tap, never with this page.

It cannot speak for the pipes inside your own walls. Lead sampling covers a handful of homes across the whole system, and your service line, solder, and fixtures are yours alone.

It says nothing about sediment at your particular faucet; annual reports do not measure what collects in one house.

Before anything goes on a quote, we ask what you are actually noticing and test whatever the published data cannot answer.
