Rancho Cucamonga Tap Water

Rancho Cucamonga tap water is contaminated with every potential toxin and contaminants that the health of those who live there could be adversely affected. This includes things like lead, herbicides, pesticides, radium, cysts, prescription drugs, and thousands of other contaminants that are known to cause various ailments in those who consume them, as well as carcinogenic agents that have been found in significant amounts. These things are not only found in the water. They’re in the air, which is why the county has implemented such a stringent air quality regulation. The irony is that this area suffers from one of the worst smog problems in the nation because the prevailing winds blow over large amounts of land surrounded by the Los Angeles and Santa Ana valleys. As a result of all of this, many of these people’s indoor air purifiers either break down or run poorly because of all of the pollutants they’re trying to filter out.

Lead poisoning is a severe problem in both children and adults, and it can often be life threatening. Testing done by the California Health Department shows a significant level of lead in the local well water, although no exact number has been determined. In addition to this, an alarming report suggests that there might be a high level of lead in the drinking water as well. This is because the pipes used to deliver the tap water to the homes also contain lead. Besides, when you shower in the house, some of the water that drips into the shower and flows out of the faucets have lead.

Because of all of these dangers, many cities and well owners are moving away from well water from Rancho Cucamonga, building units that use reverse osmosis or another filtering system. Not only do these systems cost more money upfront, but they require the installation of expensive pumps that can also add significantly to the cost of homeowners’ water use, as well as wastewater disposal systems. It is undoubtedly better to invest your money into an effective filtration system that can eliminate all tap water pollutants. Still, the reverse osmosis systems are far more costly than the other systems. Therefore, if you live in Rancho Cucamonga or have family members who do, you should consider investing in a good filtration system that removes toxins from the water.
