Forever Chemicals In San Marcos Drinking Water

Polyfluorinated alkyl substances (PFAS), also known as 'Forever Chemicals' have been found in the tap water of various locations across the United States, including parts of Texas, there's a valid concern about potential exposure and its long-term effects on public health. Monitoring and managing PFAS contamination in water sources is crucial to ensure the safety and well-being of the community.

PFAS are persistent chemicals that can accumulate in the human body over time through exposure to contaminated water, food, or air. These substances have been linked to various health issues, including liver damage, immune system disruption, thyroid disorders, and an increased risk of certain cancers.

What Are The Best Water Treatment Solutions For San Marcos?

With this combination of water resources, San Marcos water quality often faces our share of water filtration and treatment issues:

Surface water, like rivers and lakes, absorb contaminants that can be harmful for consumption as well as annoying around the home. Most of these contaminants include naturally occurring bio materials and minerals. This means water quality can worsen seasonally when warming temperatures contribute to algal blooms, or heighten water sensitivity to microorganism growth.

Ground water presents its own treatment challenges and filtration issues, so San Marcos residents with primarily ground water service may see different water problems than those using water from San Marcos’s surface water sources. Most often, these manifest as hard water problems which cause buildup on faucets and fixtures, and can be hard on appliances and plumbing.

Like many cities and towns, San Marcos draws its water water from rivers, lakes, streams, ponds, reservoirs, springs, and wells.

With surface water sources serving so much of the area, there are several factors that you should be aware of. Surface water, like water that comes from rivers and lakes, can absorb contaminants that can be harmful for consumption. Most of these contaminants contain naturally-occurring biomaterials and minerals. This will cause your water quality to worsen seasonally when warming temperatures contribute to algal blooms or heighten water sensitivity to microorganism growth.

Many of these contaminants you can not see or smell, and a typical pitcher or faucet-mount filter isn't the answer. Regardless of the water problems you’re experiencing, Culligan of San Marcos has a solution that is customized to your home -- softening, filtration, and whole home treatment.
