You see, the people of Chicago installed lead lines in their homes until 1986. There are almost 4,00,000 houses in Chicago city that still use those lead lines. When purified water from the plant passes through those lines to the houses, it gets contaminated with lead.

The City of Chicago has emphasized making people aware of lead contamination. They understand, until all those lead lines are replaced, tap water in Chicago will not be safe. For this reason, they have launched the lead service Line Replacement Program. Under this program, they are testing water for lead-free cost. They are offering free lead service line replacement to low-income homeowners. You can call 311 to get a free water testing kit from the dept. of water management.

4) Can you drink tap water in Chicago without filtering?

No, the Chicago water department never recommends drinking unfiltered tap water in Chicago. They prefer everyone in Chicago to use a water filter in their home.

5) Is Chicago tap water hard or soft? Do you need to use water softener in Chicago?

As mentioned at the beginning of this article, Chicago tap water is extremely hard. Since softening millions of gallons of hard water at a water purification plant is practically impossible, it becomes an individual homeowner’s responsibility to do it. So, if you want to protect your water pipes, washing machines, water heaters, and other home appliances from scale build-up, you have to use a water softener in Chicago. You can either opt for a salt-based water softener, a salt-free water conditioner, or an electromagnetic water descaler.

We have reviewed 2 of the Best Water Softeners for Chicago so that you can choose one for your home.

Water Softener For Chicago

Fleck 5600SXT Salt-based Water Softener

Our first choice to soften hard water in Chicago would be the Fleck 5600SXT, 32000-grain salt-based water softener by Pentair Water. It is one of the most popular and budget-friendly water softeners in the USA.

The Fleck 5600SXT gained popularity due to its high salt efficiency, reliability, and its unique features like smart regeneration, smart programming, and easy maintenance.

Fleck 5600SXT uses ion exchange technology to remove hardness-causing ions like calcium ions, magnesium ions from hard water. It does not only prevent future limescale build-up in water lines but also clears previously built scales.

It comes in various sizes, from 24000 grains to all the way up to 64000 grains. For a family of 4-5 people, a 32,000-grain water softener will be enough. But if you have a bigger family, you might choose the 40,000-grain version or higher. The system itself can pay for itself in just 3.5 years with up to $517+ in real annual savings.

Fleck 56000SXT comes with a programmable control valve which is considered the brain of this system. It controls the regeneration process on-demands making it a highly efficient salt-based system. Once you program the system to your needs, you are all set to get a steady flow of soft water for the next 10+ years. The control valve will control, diagnose and maintain the system for you. All you need to do is to add new salt every few months.  

The Fleck 5600SXT comes with a 5-year warranty for the control valve and a 10-year warranty for the water tank. For peace of mind, you will also get a month’s money-back guarantee with it. 

Yarna CWD4, Capacitive Electronic Water Descaler System

The third item you can use to soften Chicago tap water is the Yarna CWD24, Capacitive Electronic Water Descaler System. It is a standard bottled-sized electronic water descaler that turns hard water into soft water using electric impulses.

Yarna CWD24 was designed based on a thermodynamics principle. The principle states that the frequency of electric fields can increase the velocity of calcium ions in water.

The increased movement doesn’t give enough time for the ions to form calcium carbonate, the sticky white substance we all see inside water pipes and known as limescale. The electric impulse forces the ions to form vaterite, instead of calcium carbonate, smooth crystals that can not stick to water pipes.

Thus, Yarna CWD24 prevents the effects of hard water on your home appliances.

Yarna CWD24 Capacitive Electronic Water Descaler System

Using Yarna CWD24 is easy. It comes with an electronic unit and ultra-flat impulse bands. You will need to wrap the band around your incoming water pipe just like the way you see it in the picture. And then connect it to any electrical source. The computerized microchip inside Yarna CWD24 will produce electrical impulses and send them via those bands to the water to make it soft. It takes about 15 minutes to completely install the descaler in your home.

You won’t need to cut your water pipe to install the system, making it the easiest method of dealing with hard water.

Yarna is so confident about their water descaler that they give a whole year money-back guarantee with it. If you are not satisfied with Yarna CWD24, you can return it for a full refund.

6) Is there chromium 6 in Chicago drinking water?

Chromium 6, also known as Hexavalent Chromium, is an unregulated water contaminant. That means the Environmental Protection Agency has not yet set the standards for Chromium 6 present in drinking water. Still, the Chicago Water Management Board (WMB) monitors the levels of chromium 6 in Chicago’s tap water. Their monitoring report helps EPA determine whether they need to regulate chromium 6 in the future or not.

Under the Unregulated Contaminant Monitoring Rule 4, Chicago WMB tests for Chromium 6 four times a year, The latest report published at the end of 2020 shows that Chicago water samples contain chromium 6 in trace amounts. The contamination level varies from time to time and location-to-location. For example, a water sample taken from the Field Reagent blank area contained 0.15 micrograms of chromium 6 per liter in Q1,2020 and 0.07 micrograms per liter in Q4,2020. The entire monitoring report is attached here. Do take a look.
