Arsenic Water Filtration in Corpus Christi

Whole-House & Reverse Osmosis Filtration Systems for Nueces County Homes & Businesses

Arsenic is odorless, colorless, and tasteless. You can’t detect it without testing, yet the EPA classifies prolonged exposure above its Maximum Contaminant Level (MCL) of 0.010 mg/L as a serious health concern linked to certain cancers and cardiovascular issues. At Custom Filtration & Plumbing Co., we’ve been installing water filtration systems for Corpus Christi and Nueces County residents since 1996, and our licensed, full-service team handles confirmed arsenic problems with a complete installation process.

We install Point-of-Entry (POE) whole-house filtration systems and reverse osmosis (RO) systems for residential and commercial customers throughout the Coastal Bend. Our background-checked, licensed technicians handle both the assessment and the complete installation as a single-provider solution. Flat-rate pricing is provided upfront, and financing options are available.

Arsenic in Nueces County Water: What Local Residents Should Know

Corpus Christi Water draws from multiple sources, including Choke Canyon Reservoir, Lake Corpus Christi, Lake Texana, and the Colorado River via the Mary Rhodes Pipeline, all treated at the O.N. Stevens Water Treatment Plant. The city’s most recent official testing confirms arsenic levels below the EPA MCL for its municipal supply. Not every district in the county shares that status, however. In January 2026, Nueces County Water Control and Improvement District No. 3 (WCID #3), which serves the Robstown area, recorded arsenic at 0.0115 mg/L, above the EPA MCL of 0.010 mg/L, and TCEQ issued a violation. We serve that area and have detailed that specific event on our EPA violation page linked from our homepage.

Even when municipal water meets legal minimums, some households choose additional filtration. Families with infants, elderly residents, or immunocompromised individuals often want a layer of protection beyond what compliance requires. Whether you’re in the Robstown service area or elsewhere in the Corpus Christi region, certified filtration can address the concern directly.

POE Systems & Reverse Osmosis: Choosing the Right Arsenic Filter

The two most effective approaches to arsenic reduction in residential water are Point-of-Entry filtration and reverse osmosis systems. They work differently and serve different needs. Standard pitcher filters and most refrigerator filters aren’t certified to remove arsenic effectively; these technologies are the right tools for the job.

We don’t apply a one-size-fits-all recommendation. Our technicians assess your water and your home’s plumbing before suggesting a system, because arsenic concentration, water chemistry, and household usage all factor into the right solution.

• Point-of-Entry (POE) Whole-House System: Installed at the main water line where water enters the home, a POE system filters every tap, shower, and appliance. It uses activated alumina media or similar certified filtration to reduce arsenic before water reaches any fixture, making it a comprehensive option for households with broader exposure concerns.
• Reverse Osmosis (RO) System: Installed at a point of use, such as under the kitchen sink, an RO system forces water through a semipermeable membrane that reduces arsenic and a wide range of dissolved contaminants. Treated water collects in a tank and is drawn on demand. One of our customers put it plainly: “I had a reverse osmosis system installed and am extremely pleased with the entire process. Reasonable rates, friendly people, quality work.”

Both system types should carry NSF/ANSI certification for the specific contaminants they claim to reduce. We install systems sized and certified appropriately for your application.
