Water Quality in the State of Indiana

Located in the Great Lakes region, Indiana has a population of 6.7 million people, with the most populous city being Indianapolis. The state has a deep history with motorsports, hosting the first long-distance auto race in the year 1911, and is well known today for the annual Indi 500 races. Indiana has an abundance of waterways, with more than 35,000 miles of rivers, 100,000 acres of lakes and reservoirs, and Great Lake, bordering the upper eastside.


Indiana's primary surface water sources are provided to industry, agriculture, and energy as a crucial part of operations. Residents subsequentially depend on groundwater for their potable water usage. 


Water Hardness by City

Indiana has very hard water. The average water hardness for the state is 262 PPM. Indianapolis, the largest municipality in Indiana, has a water hardness level of 274 PPM. Some of the hardest water in the state comes from South Bend (370 PPM), Lafayette (382 PPM) and Sommerset with an extremely hard number of 400 PPM.


For more information on the water hardness in specific cities, please see the table below.

Indianapolis 274 PPM (mg/L) or 16 gpg
Fort Wayne 113 PPM (mg/L) or 7 gpg
Evansville 124 PPM (mg/L) or 7 gpg
South Bend 370 PPM (mg/L) or 22 gpg
Carmel 137 PPM (mg/L) or 8 gpg
Elkhart 342 PPM (mg/L) or 20 gpg
Bloomington 339 PPM (mg/L) or 20 gpg
Lafayette 382 PPM (mg/L) or 22 gpg
Gary 144 PPM (mg/L) or 8 gpg
Somerset 400 PPM (mg/L) or 23 gpg
Muncie 284 PPM (mg/L) or 17 gpg

Advanced Manufacturing and Water Hardness

Indiana has been the leading steel producer in the United States for more than four decades. They produce more than twice the second steel-producing state in the US (Ohio), contributing to more than a fourth of the nation's steel. Steel requires a great deal of water during processing.


With water hardness levels as high as 400 PPM in some Indiana cities, steel manufacturing equipment can rapidly clog up with hard scale deposits and necessitate costly facility-wide shutdowns for maintenance and repairs. Often times, chemical treatment can be inconsistent and facility managers are required to look outside of their regular chemical regimen for a more permanent and dependable solution to protect their equipment and maximize process run time.


Solutions to your Water Quality Problems

Fixing your water quality issues in the state of Indiana will depend on your specific water source. It is best to test your potable water supply in order to get a better understanding of your water quality. Testing is relatively cheap. The test results will allow you to understand if your potable water has issues that need to be addressed. Common solutions to water contamination problems may include a water filtration system, a reverse osmosis system or other whole home water treatment solutions.


A problem that almost all Indiana residents will have to deal with is hard water. One old-fashioned, inefficient, expensive and unhealthy method to treat hard water is with a salt-based water softener. Most people don’t realize that if you’re using a water softener you are basically removing calcium and magnesium from your drinking water and adding salt to your diet. In addition, many states are banning the use of salt-based water softeners. 



Alternative water treatment solutions such as “water conditioners” have been gaining popularity in recent years because they are cheap to operate and the best eco-friendly solution for hard water. Hydropath technology, which powers the HydroFLOW water conditioners is by far the most efficient and cost-effective eco-friendly solution to deal with hard water problems.
