Water Quality in Norman, OK- Is Norman Water Safe to Drink?
If you’re wondering about the water quality in Norman, you’ve come to the right place. Generally speaking yes, Norman water is safe to drink, however there are many contaminants such as arsenic, that could lead to suboptimal outcomes for your health over time. The City of Norman has had ongoing struggles to keep naturally occurring levels of arsenic down. Some homeowners also notice hard water deposits, chlorine/chloramine taste or smell, cloudy water or iron staining while other contaminants may go undetected.
Where Does Norman, OK Get Its Water?
Norman’s municipal water is sourced from three places: Lake Thunderbird’s surface water, ground wells from the Garber-Wellington aquifer, and Oklahoma City tap water. The water from Lake Thunderbird is treated at the Campbell Water Treatment Plant through a combination of coagulation, ozonation, filtration, chloramines, and UV light to make it safe to drink. It is also softened. While it meets the EPA’s safety regulations, some contaminants may be unregulated, have outdated limits or may impact taste or smell.
Does Norman Water Contain Arsenic?
Yes, Norman water contains naturally occurring arsenic along with many other central Oklahoma municipalities that depend on the Garber-Wellington aquifer for water. When the EPA lowered the maximum contaminant level for arsenic in drinking water in 2006 from 50 ppb to 10 ppb, the City of Norman lost about half of its well field due to high levels of arsenic because some wells exceeded 40 ppb. The City of Norman took action in 2007 to pilot an arsenic removal system which utilizes an iron based absorption media. It has since been successful at keeping arsenic levels below the EPA maximum contaminant level but private well owners are responsible for testing their water.
Arsenic
EPA Max contaminant level: 10.0 ppb
EWG Health Guideline: >.004 ppb
National Average: 0.624 ppb
What Contaminants Are In Norman’s Water?
According to the EWG tap water database, Norman’s water also contains Radium, Nitrates, Fluoride, and Haloacetic acids (HAA5) which is a disinfection byproduct. While these substances are within the EPA’s maximum contaminant limits (MCL), the numbers could be significantly reduced or removed with reverse osmosis (RO) filtration.
Uranium
EPA Max contaminant level: 20 pCi/L
EWG Health Guideline: >0.43 pCi/L
National Average: 1.03 pCi/L
Chromium (hexavalent)
EPA Max contaminant level: 100 ppb
EWG Health Guideline: >.02 ppb
National Average: 0.44 ppb
Does Norman, OK Have Hard Water?
Yes, Norman water is hard depending on the source. Water coming from Lake Thunderbird is hard but it is softened by the city. Whereas private well water can range from 18-100 grains hard. If the water is imported from Oklahoma City’s Lake Hefner, we typically see it around 18 grains hard. A water test will allow us to give you an exact hardness for your home or business.

The Proof
Why Do Norman
Homeowners LOVE Us?
We recently went on well water and even though it’s good water, it’s very hard. The Culligan salesman was easy to work with and the techs were very fast and efficient at installing / setting up the softener.
These guys saved the day for us. Our hard water was so bad it was destroying all of our faucets and appliances. They were fast, friendly, and extremely professional.
We have had Mollman’s residential water softener service for over two years, and it’s great. We have well water, and before having the softener our dishes came out of the dishwasher looking terrible, with deposits all over them. You could also tell there was long term build-up in many of the faucets, some which we had to replace. Since having the softener our dishes come out sparkling and we don’t see residue on any appliances or faucets. We haven’t had any issues with the service, and the company is prompt to answer any questions.
