Water Quality in the State of Delaware

Delaware residents get their drinking water from either groundwater or surface water sources, depending on where they live. About two-thirds of Delaware households are connected to public water systems that use groundwater sources; the remaining one-third obtains water from surface water sources. The major sources of groundwater are the Columbia Aquifer, the Cheswold Aquifer and the Piney Point Aquifer. All surface water plants for Delaware reside in northern New Castle county. The major sources of surface water are the Brandywine River Basin, Christiana River Basin, Red Clay Creek and White Clay Creek.

 

Water Hardness Summary

Delaware water is considered hard to very hard. The average water hardness for the Delaware resident is 100-300 PPM. Wilmington is the most populous city in Delaware with a population of just under 71,000 people. Wilmington has relatively hard water with 127 PPM.

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

 

City	Water Hardness in Data
Wilmington 19801 |19802 | 19803 | 19804 | 19805 | 19806 | 19807 | 19808 | 19809 | 19810	127 PPM (mg/L) or 7 gpg
Dover 19901 |19904	64 PPM (mg/L) or 4 gpg
Newark 19702 |19711 | 19713 | 19716 | 19717	122 PPM (mg/L) or 7  gpg
Middletown 19709	119 PPM (mg/L) or 7 gpg

PPM = Parts Per Million

mg/L = Milligrams Per Liter

gpg = Grains Per Gallon

Farming and Water Hardness

The farming and food processing industry are thriving sectors in Delaware. The largest farming product is broiler chicken, producing $946 million in gross product a year. This stems from the fact that large chicken corporations like Perdue Farms and Mountaire Farms call Delaware home. Field Corn (which is used for livestock feed and ethanol) is another large agricultural industry for Delaware, attributing to $108 million of Delaware’s yearly revenue. Other top agriculture products from Delaware are soybeans, chicken eggs, wheat, dairy products, sweet corn, watermelon, cattle and barley.

As a great deal of Delaware has water rich in calcium (the primary source of water hardness), many farms and food processing plants experience issues related to scale buildup in their irrigators, production and processing equipment. In addition, contaminants polluting soil and waterways has increased greatly over the past few decades and there is a greater need for waste and chemical control. Many farmers are looking for eco-friendly solutions that can increase the quality and yield of their crops while saving water. Read more about how HydroFLOW can increase crop yield.

Solutions to your Water Quality Problems

Fixing your water quality issues in the state of Delaware 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 Delaware 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.
