Choosing Sulfur Filters

Choosing Sulfur Filters

Water Medic of Cape Coral dropped a detailed blog post that walks homeowners through everything they need to know about choosing sulfur filters for well water. The article starts by explaining that the "rotten egg" smell comes from hydrogen sulfide gas trapped in groundwater, but goes beyond just the odor to cover the real damage happening behind the scenes. The team highlights how the gas corrodes pipes, stains fixtures, and tarnishes silverware, positioning sulfur filters as infrastructure protection rather than just odor control. Water Medic breaks down three main treatment technologies: air injection systems that use oxygen bubbles to convert gas into filterable particles, chemical oxidation systems that inject chlorine or hydrogen peroxide, and catalytic carbon filters that trap sulfur through specialized activated carbon. They dive into total cost of ownership, noting that annual operating costs range from under $150 for low-maintenance air injection systems to over $500 for chemical-intensive units.

EPA to Partially Scrap PFAS Standards

The Environmental Protection Agency just filed a motion asking a federal appeals court to partially throw out its 2023 PFAS drinking water rule, basically admitting it messed up the process. WaterWorld's Bob Crossen reports that the motion targets four specific PFAS compounds (PFNA, PFHxS, GenX, and "Hazard Index PFAS") while keeping the standards for PFOA and PFOS intact. EPA admitted it violated the Safe Drinking Water Act by rushing through both the regulatory determination and the actual drinking water standards at the same time, which didn't give stakeholders a real chance to comment. The American Water Works Association challenged this, arguing the agency imposed costly standards without proper public input. This creates a headache for utilities since many have already started paying for and installing PFAS removal systems to comply with the rule that EPA now wants partially tossed. The motion lines up with EPA's earlier push to extend compliance deadlines from April 2029 to 2031, giving utilities more time to figure out treatment technologies and capital spending.

School-Safe Science Project

PA-based Dierolf Plumbing and Water Treatment put together a blog post that turns school water contamination into a classroom project for middle schoolers. In it, the team writes about real Pennsylvania examples of why this is important; NBC10 found four schools with PFAS above state limits, WHYY reported schools weren't always quick to fix lead problems, and Berks County had to deal with Legionella bacteria in their water systems. The post walks through a 5-step project using EPA's 3Ts framework where kids can map drinking spots around school, dig up their school's water data, organize the results, compare them to safety levels, and suggest what to do next. The team includes a helpful glossary that explains technical terms in ways that actually make sense (like describing parts per billion as 1 second in 31 years). They also cover Pennsylvania's rules, pointing out that schools don't have to test every year but need to hold public meetings if they skip testing, plus they break down different action levels for lead and PFAS.

2025 Buyer’s Guide

Freedom Water Systems published their 2025 whole house filtration guide that leads with market projections, explaining that the filtration market is expected to grow from $14 billion in 2024 to $35 billion by 2034. The team uses the educational content to position themselves as industry experts while highlighting two trends shaping customer expectations: smart monitoring with app reminders and sustainability features that reduce waste and plastic cartridges. The guide covers the usual technology breakdown as well: activated carbon for taste and odor, advanced carbon blends for PFAS reduction, scale control options, and add-on reverse osmosis for drinking water. Freedom Water walks through the practical stuff like sizing systems for peak household demand and planning maintenance schedules, and keeps circling back to their own ECO-X and Platinum series products as top solutions.
