Tap Water Quality in Ventura

In and around Ventura, the biggest problems with drinking water generally stem from issues with the surface water supply. Depending on the season and the climate, surface water can require extra treatment to make sure it’s safe to drink, and this process can often leave your water tasting less than its best.

There are also many minerals and impurities that municipal treatment doesn’t remove, or doesn’t completely remove. Some of these include potentially harmful contaminants like lead, hexavalent chromium (chromium-6), arsenic, and others.

Because Ventura uses a surface water system for most of the city, with the exception of a few wells to supplement supply here and there, there’s typically a greater risk of contamination because water doesn’t pass through a natural filtration system the way groundwater does.

"The reverse osmosis taste is, again, delicious. I used to love going to work for the great water, now I fill up my water bottle before leaving the house because I prefer our waters taste over everyone else. Yeah, I've become a water snob. It's a luxury that I appreciate." - Oscar G., Carpenteria

It took me 2 years to decide on the company and I can say that this is a great company, with an amazing customer service. My water tastes excellent and I don't think I could have had it better. Clara B., Studio City

Frequently Asked Questions about Culligan Reverse Osmosis Systems

I have heard a lot about Chromium 6 in drinking water in the news. What is Chromium 6 and can Culligan equipment filter out Chromium 6?

Yes, chromium six (or hexavalent chromium) has recently been discovered in limited amounts in some water supplies. Chromium six is suspected of being a carcinogen, and should not be ingested at amounts above the federally mandated limits.  We have never been alarmists, but if you are concerned about the quality of the water you drink, you might want to consider a reverse osmosis system.  Reverse Osmosis is the only readily available system that removes up to 97% of chromium six.

  1. What is Reverse Osmosis (R.O.)?

Reverse osmosis is a sophisticated multi-stage filtration system that is capable of removing up to 97% of all the dissolved minerals from your water.  It is designed to make water that is at least as good as the water you buy in bottles.  Many times, it’s even better.  This reduces waste in landfills by using less bottled water, making reverse osmosis environmentally friendly.

  1. Is Reverse Osmosis water really as good as bottled?

Yes - The system uses multiple processes including Reverse Osmosis to make great tasting, low sodium drinking water. Reverse Osmosis removes about 97% of the TDS (Total Dissolved Solids) including salt and sodium from the water. Read the labels on bottled water and you will discover Reverse Osmosis is the same process used by most bottlers ... so in effect ... you really are getting ... "bottled water ... without the bottle".

  1. I already have a filter in my refrigerator? Why do I need anything else?

Refrigerator filters are typically just carbon, and while carbon filtered water is better than no treatment at all, it is limited in what it can remove. Only reverse osmosis is capable of removing dissolved minerals and chemicals from your water.
