Common CA Tap Water Contaminants: The Concerns That Affect Everyone

DU JOSIP - Updated January 11, 2024
The adage “You do not appreciate the value of something until it is no longer available” is accurate. There have been many safety issues with tap water in recent years, directly affecting the lives of the local population.The Environmental Protection Agency aims to decrease the lead action level from 15 to 10 parts per billion.
Environmental Working Group (EWG) analysis reveals that about 218 million individuals consume tap water with varied levels of contamination from the hazardous hexavalent chromium. The number of distinct contaminants present in our drinking water is evident.
Awareness about the safety and purity of tap water is growing steadily. We must take immediate action regarding the quality of the water we consume daily. From which source does the tap water originate? What kind of pollutants are generated throughout the process? Where can I get the information? What is the appropriate way to manage or deal with it?

Is Tap Water Safe to Drink?

Identifying the origin of the water is necessary before we can have a complete understanding of the answers to the problem of water pollution.
The majority of the water that is used for drinking comes from either surface water or groundwater. In order for water to reach our taps, it must first travel from several sources, including but not limited to ponds, lakes and rivers, springs, reservoirs, streams, and wells. Following the collection of water by filters at water treatment plants, the water is subsequently supplied by water pumps and distributed by pipes to all of the outlets in our homes.
However, there are many pollutants involved in this process. The presence of microbiological pollutants, heavy metal contamination caused by old pipes and equipment, chlorine that is left over following water treatment, and pollution from industrial and agricultural effluent that reaches the water source are all causes for concern.
As we can see, it is not easy to deliver pure water suitable for human consumption using this technique. Sometimes, even the purest water from faucets is not safe to consume.

Which Common Contaminants Are in Tap Water?

The primary pollutants in our daily drinking water may be classified into four groups: inorganic substances, such as toxic metals like lead and mercury, and microorganisms. The mentioned substances include bacteria, viruses, parasites, radioactive elements such as uranium and radium, and chlorine, which results from the water treatment process. In addition, organic pollutants include industrial and agricultural contamination, such as pesticides and herbicides, as well as leachate from home items, such as PFAS .
Nevertheless, the ingestion or proximity to certain compounds may elicit very precise physiological responses in our bodies.
Chlorine is often used to sanitize municipal water systems. While small quantities may not cause damage, excessive volumes of chlorinated water or its byproducts may have detrimental effects on your well-being. Prolonged exposure to the byproducts may heighten the likelihood of developing cancer and induce irritations of the skin and eyes.

Lead is present in older pipe networks and facilities, especially those that have undergone pipe replacement or ancient infrastructure projects. While a little increase in lead levels in the body may be considered within the normal range, higher levels of lead in water may lead to adverse effects such as learning impairments, delays in development, and even hearing impairment in children. In addition, they have the potential to induce gastrointestinal discomfort, constipation, and weariness.

Chemical plants and areas with industrial pollution are familiar sources of PFAS contamination in water. It exhibits resistance to decomposition and finds use in firefighting foams, anti-fouling paints, and other compounds used for waterproofing and preventing fouling. This substance has the potential to alter the endocrine disruptor and has been associated with several health problems, such as immune system dysfunction, thyroid disorders, elevated cholesterol levels, and other related difficulties. It increases the likelihood of some types of malignancies. Prolonged intake has been linked to health complications in pregnant women and their infants.
Most natural water sources naturally contain Fluoride. However, many local areas supplement their water supply with additional Fluoride to prevent tooth decay. When taken in moderation, Fluoride is advantageous for dental health, but excessive use may lead to dental fluorosis or skeletal issues. A home water filtration system addresses the issue of removing Fluoride from water and obtaining water free from Fluoride.

How Can We Find Out What Pollutes the Water in Our Neighborhoods?

Several methods are available for local residents to monitor the real-time water quality. Although these approaches include some reference value, they need to be revised in comparison to professional evaluation departments and organizations.
If you possess a pragmatic mindset. Subsequently, you have the option to acquire water test strips for assessing the quality of your home’s water supply via Internet platforms or physical specialized shops. The color of the test strip changes during immersion in tap water, following the instructions, therefore providing a general indication of the extent and type of water pollution.
In comparison, a diverse selection of home water test kits are available for purchase. These tests often assess for prevalent contaminants such as lead, chlorine, and hardness, which refers to the presence of calcium and magnesium ions. These tests will provide more precise findings than a conventional test strip. If you possess the necessary funds, you have the ability to collect a water sample and dispatch it to an authorized laboratory for a more comprehensive examination.
To expedite and simplify the process of obtaining the necessary information, it is advisable to use the websites of your state and municipal health or environmental protection authorities. At that location, you may get water quality data and relevant health notifications about your vicinity.

Additionally, you may expect the forthcoming development of a webpage on our official website that will enable you to search for toxins in close proximity based on your zip code. Currently, we are in the process of testing this functionality. However, shortly, you will be able to use our interface and utilize the query function to determine the presence of contaminants in the water supply within your local area promptly. Information openness is crucial for obtaining accurate data on drinking water quality.

Ideal Resolution - Purchase an RO System to Remove Contaminants From Your Water.

The reverse osmosis system is sometimes referred to as a water purifier. The cartridge is primarily composed of PP cotton, activated carbon, and reverse osmosis water membrane, among other elements. The water purified using reverse osmosis (RO) is drinkable, indicating that it consists only of H2O molecules, and the filtering precision is 0.00001 microns.
Reverse osmosis (RO) is a very effective technique for removing bacteria, viruses, scale, heavy metal ions, smells, sludge, colloids, suspended debris, and humus from water. The total dissolved solids (TDS) content is often reduced in water filtered by a reverse osmosis (RO) water purifier. Both boiling and consuming directly from the RO filter are viable choices for this kind of water. The most prominent characteristic is that the kettle or electric heater will no longer accumulate mineral deposits.
Consuming water purified by a reverse osmosis (RO) cartridge for an extended period will not adversely impact the body. This is because the water is filtered via a membrane, ensuring the removal of dangerous chemicals.
