Choosing the right water treatment for your home this week means understanding the hardness present in your area's groundwater and how it varies over time.

How seasonal or multi-year variation shows in the record

Groundwater samples span 2011 to 2017

Two wells in Connecticut's aquifer 112DFSF were sampled three times between September 2011 and September 2017. This range helps illustrate multi-year variation rather than short-term seasonal changes.

Hardness levels range noticeably but remain consistent

The recorded hardness concentrations vary from 74.7 to 154.0 mg/L with a median of 105.0 mg/L, showing some fluctuation without abrupt spikes or dips over these years.

Sample depths of 19 to 24 feet reflect shallow groundwater conditions

These depths indicate the water quality data corresponds to relatively shallow wells, which may be representative of typical residential well depths in the region.

What happens when this problem is left untreated for years

Hardness minerals can cause scaling over time

Calcium and magnesium hardness minerals tend to precipitate as scale on plumbing fixtures and inside appliances, reducing their efficiency and lifespan gradually.

Accumulated scale may increase water heater energy usage

Deposits impede heat transfer, causing water heaters to consume more energy to meet household hot water demands.

Fixtures and faucets may appear dull or experience reduced flow

Without treatment, mineral buildup can reduce water flow and cause visible scaling on surfaces that contact water regularly.

How the documented treatment technology removes or neutralizes the constituent

Salt-Free Scale Control System alters hardness minerals physically

The C-Series Salt-Free Scale Control System employs a technology that changes the behavior of hardness minerals so they do not form scale deposits inside plumbing.

No salt or chemicals are added to the water

This system does not rely on salt for ion exchange but uses a salt-free method that preserves existing mineral balance while controlling scale formation.

Ships ready to configure for residential use

The equipment comes ready to connect to home water lines without requiring specialized plumbing services.

What 'detected', 'median' and 'range' mean in the sampling record on this page

Detected means the instruments measured hardness minerals

All three sampled results detected hardness minerals; none were below the reporting limit, confirming their presence in the aquifer but not indicating any safety issue.

Median represents the middle value of measured concentrations

A median hardness of 105.0 mg/L indicates half of the samples measured below this and half above, providing a balanced summary of concentration levels.

Range shows the spread between lowest and highest values

Values from 74.7 to 154.0 mg/L define the observed minimum and maximum hardness concentrations during the sampling period, indicating variability.

None of the results exceeded federal health-based thresholds

The samples did not exceed any federal limits related to health, emphasizing that these levels are typical for the aquifer and not unsafe.

What the reader should write down before asking anyone for treatment advice

Your well's water test results for hardness

Obtain a certified laboratory test of your own water to determine specific hardness levels and other constituents.

The depth and age of your well

Note the well characteristics to compare with the sampled wells’ data from your aquifer.

Any noticeable effects of hardness in your home

List observations like scale buildup, appliance performance changes, or water flow issues.

Maintenance rhythm of the documented technology in plain terms

Periodic system checks recommended

The C-Series system requires routine attention to maintain optimal scale control performance, with intervals depending on household water usage.

Simple upkeep without salt replenishment

Since this technology is salt-free, it avoids the regular salt recharging that traditional water softeners need.

Component replacements as indicated by manufacturer guidance

Certain parts may need occasional replacement to keep the system functioning efficiently, ensuring continued scale control.

Do not conclude your household water hardness level or treatment needs solely from the area's groundwater data. A specific water test of your own well is essential to make an informed decision about salt-free water softening.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2017-09-06. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
