Historically, Corona, California is the location of the Nation’s first lemon-processing plant, but it would also eventually become the location of some of the worst tap water in the United States. In this article we’ll explore more about Corona’s drinking water problems. 

So, first of all, where does Corona’s tap water come from? Actually, it comes from a few different places. Water found in Corona’s tap is a blend of well water, groundwater and water that is imported from the Metropolitan Water District of Southern California. 

Currently, the city of Corona serves more than 150,000 residents out of three water treatment facilities. The city’s goal is to develop its existing infrastructure of water wells and to build storage reservoirs that will better serve the community. But that’s in the future. What’s helping Corona’s water supply now?

Unfortunately, not much. The city’s water supply contains a host of impurities that are above federal health limits. Corona’s city water supply was found to be contaminated with 1,2,3-Trichloropropane, Bromodichloromethane, Bromoform, Chloroform, Chromium (Hexavalent), Dibromochloromethane, Nitrate, Radiological contaminants, Trichloroacetic Acid and Fluoride. All of these contaminants were found, by 3rd party independent testing, to exceed health guidelines for drinking water. And that’s not all. 

After traces of toxic chemicals like perfluoroalkyl and polyfluoroalkyl substances (PFAS) were found in nearly 300 of California’s drinking water wells - in an area affecting almost 9 million Californians - Corona’s water authority was forced to send water from their affected wells through a water treatment plant. This was done in lieu of shutting down the entire Corona city water facility. At the time, eight of the water wells tested were found to contain impurities that exceeded EPA health limits.  

According to an Los Angeles Times article, the contamination was left in “pockets,” which occur when chemicals seep into specific areas of the public water supply. Back in the day, PFAS chemicals were used in industry, manufacturing and in normal household products. 

A Consumer Reports article states that California’s Latino-majority communities are hardest hit by its contamination issues, with an estimated 5 million people drinking water above the federal EPA limits for nitrates. What’s worse is that advocates estimate even more people could be at risk from contaminated water because of  private wells, which aren’t tested - or even regulated - by the EPA.

For those who live in Corona, California, an at-home water filtration device will give your family access to clean, quality drinking water, and give you the power over your tap. Simply put, we can’t trust that water supply agencies will get the job done when it comes to decontaminating our water. City water authorities work to remove contaminants but often fall short in the long run. In the end, impurities and contaminants slip through the cracks and find their way to residential taps all too often. Further down we’ll talk more about water filtration and how a water filtration system can provide your family with cleaner, healthier water, but first, let’s talk about how Corona’s water supply became so bad in the first place. 

How did this happen?

There are a few different factors that combine to create the perfect storm that makes a state’s water quality substandard. 

1. Deteriorating infrastructure - The first reason deals with the infrastructure of the municipality supplying the water. In a perfect situation, public water pipes would remain in tip-top condition but in the real world, they don’t. Here’s a common example seen in deteriorating pipes: If a water pipe becomes old and starts to leak it can create a vacuum-like situation pulling untreated water in with treated water. When you turn on your faucet, your water would be both treated and untreated. 
2. Deteriorating infrastructure (part 2) - Another problem with old pipes is that they can seep copper, lead and additional heavy metal impurities - inviting a dangerous and unhealthy cocktail of contaminants into your drinking cup.  
3. Hazardous runoff - Hazardous tap water is also caused by runoff from farms and manufacturing plants, like car-making plants and coal mining plants. Runoff seeps into our water bodies and then gets into our water supply. 
4. Adding chlorine - Municipalities often add chlorine to the water supply in order to improve the taste or smell of the water; but it’s not safe. 

How can I find out if my home has bad tap water in Corona, CA?

Ask your provider.

The first thing you should do is call or email your local water provider and ask them to give you a copy of the most up-to-date water quality report they have. This report will detail the exact tests done to the water in your area with the dates the tests were performed and the results of the tests. The test results will give you insight into what contaminants may have been detected in your water. After that you can decide to have further testing done or you could move forward satisfied with what the report says - either way now you have information about the likely contaminants in your water.  

Send samples for testing.

The most thorough testing will occur when you send out a sample of your tap water - this will also give you the most accurate results. You should always send your sample to a certified water-testing lab because they hire experts who will know what to look for. As an example: some chemical contaminants are hard-to-detect and can be overlooked by novice testers. Professional water labs will check for bacteria, chlorine, lead and pesticides as well as any specific contaminants you request. 

Test your water at home. 

You can also do it yourself and if that’s something you enjoy, there are water testing kits that can be purchased to make that happen. Professional lab testing is the most accurate and thorough way to test water - but with that said, at-home water testing kits can provide you with crucial information on your drinking water. 

You can buy a kit online or in your local hardware store. The test strip kit will give you instructions on how to perform a test at home. Here’s an important tip: when testing your water at home, yourself, do it twice. Testing your water two times will ensure that your results are accurate. If you find that impurities are present, consider investing in a good water filtration device. A good water filtration system will help you to eliminate many contaminants and bring your drinking water to its most healthy and pure state. Finding a good, reliable water filtration system may be a daunting task - so let’s talk about the best system available to you.
