dissolved solids in water

What are Total Dissolved Solids in Water?

A total dissolved solid, also known as TDS, measures the total amount of inorganic and organic substances in a liquid.

A high level of TDS typically indicates hard water, which can result in scale build up in appliances, pipes, and hot water tanks. In addition to reduced lifespan, scale buildup can increase maintenance cost and impact performance.

Furthermore, consuming water with a high TDS can impact your health (more on this below). 

Many of the most common dissolved inorganic water contaminants exist as ions in water. Some of these include:

  • Calcium
  • Magnesium
  • Sodium
  • Iron
  • Manganese
  • Bicarbonate
  • Chloride
  • Sulfate 
  • Nitrate
  • Carbonate

Generally speaking, these water contaminants have no impact on human health, making it okay to use water supplies with inorganic water contaminants. However, if present in large quantities, some types of contaminants can be toxic. This is why it’s important to protect against all contaminants.

In addition to inorganic contaminants, water can also contain organic contaminants, which includes anything that enters the water as the result of human activity. Examples include pesticides and insecticides. 

Should You Measure TDS Levels?

If you have any concerns about your home’s water quality – and even if you don’t – it’s good practice to regular measure TDS levels. 

When TDS levels reach 1,000 parts per million (ppm) or higher, you should take immediate action. This means the water is not fit for consumption. 

Upon professional investigation, you’ll gain a better understanding of why your TDS level is high and what you can do about it. 

For peace of mind, regardless of your current TDS level, consider installing a whole house water purification system. With this in place, you’ll have peace of mind in knowing that every ounce of water you come into contact with has been purified. 

Tip: even if you have a purification system in place, continue to regularly monitor for TDS. 

The water you come in contact with should never have a negative impact on your health. If you have any concerns about water contaminants, don’t wait another day to take action.

What Our Customers Say

We were extremely pleased with the service provided by Dan R from CGC Home Services. He arrived on time and was very thorough in checking out our system, identifying the problem and fixing it. It was a pleasure having him here, and he is the guy we would want to come if we ever need service again.

Services performed by CGC were as promised and performed professionally by Matt, the service representative. We was quick and carefully explained everything regarding the water treatment system he installed and answered any questions we had. I have very comfortable dealing with CGC and I am confident that all the techs we have had over the years represent the same performance level as Matt.Thank you CGC

Excellent experience with CGC! Abraham was amazing to work withvery knowledgeable, professional, and easy to talk to. He made the process simple, took time to educate us without being pushy, and made sure we felt comfortable every step of the way. You can tell he genuinely cares about his customers. Highly recommend asking for Abraham if you work with CGC!

Great service

Shane came this afternoon to service our water system. He did a great job. Told me some things I wasn't aware of about when to change the water filters. He was very nice and polite. I would recommend CGC Homes Services if anyone had a water system issues or plumbing problems.

Very friendly and professional

As a new resident of Ponte Vedra Beach, I was unfamiliar with the water quality in St Johns County. We were noticing an odor from our faucets and buildup on our fixtures. I began asking my neighbors about water systems and time and again they mentioned CGC Home Services. I called for an in home evaluation and quote. Abraham Rukab arrived promptly and provided an informative and honest assessment of our current system and addressed our concerns. He was very knowledgable and patient with all of our questions. We decided to get a new softener with whole house filter as well as a reverse osmosis drinking faucet. Abraham and CGC went above and beyond our expectations...fitting us in for a new system the very next day! The installation went just as smoothly! Our tech explained our new system, how to change the filters, when to add salt and where to look if we have questions. It's been 2 weeks and we couldn't be happier with our new system! No smelly water, clean fresh drinking water and beautiful soft water! I highly recommend Abraham and CGC for all your water needs!

Prompt service. Jordon explained everything while he was troubleshooting and making repairs. Very nice and friendly technician. The repair was under warranty.

Thanks to Dan at CGC for confirming that our water softener and air oxidizer are working as intended! Best of all, you didn't try to sell me something that we didn't need This has helped me narrow down the rotten egg smell to a degraded anode rod in the water heater Thanks again, Scott
