Greenwater Services

Greenwater Services (also referred to as Green Water Solutions) is a United States-based water treatment company that specializes in the remediation of contaminated lakes, reservoirs, rivers, and other water bodies. Its core offering is a patented NanoBubble Ozone Technology (NBOT) system, which the company describes as a chemical-free, all-natural disinfection platform that uses ozone infused into nano-bubbles to generate hydroxyl radicals. According to the company, these radicals oxidize and destroy organic compounds, reduce algae, microcystins, nitrates, and phosphates, and leave only oxygen as a by-product, thereby returning contaminated water toward its natural state. The company markets its technology to agriculture, data centers, government agencies, and municipalities — sectors that depend on clean water and are increasingly affected by harmful algal blooms (HABs). Greenwater Services provides both portable NBOT units for small-scale or temporary treatment and permanent installations for ongoing, large-scale water quality management. Supporting products include high-efficiency ozone generators, nano-bubble diffusers, and water quality sensors for continuous monitoring. Beyond hardware, the company offers consulting, customized solution design, and full project management for water remediation projects. Greenwater Services states that its NBOT system has been deployed in several locations, including the Lock at Port Mayaca in Florida, Lake Sylvan, and lakes in Ohio, with reported improvements in both chemical makeup and visual clarity. The company emphasizes the efficiency of its nano-bubbles — which are buoyantly neutral, do not rise to the surface, and achieve an ozone absorption rate of 95–98% — as well as the safety of the process for humans and marine life. It also claims that the hydroxyl radicals generated are over 20,000 times stronger than chlorine. Ownership of the company is recorded in Wikidata as the J.J. Cafaro Investment Trust. Greenwater Services continues to promote its technology at industry events, such as the 13th U.S. Symposium on Harmful Algae, where it planned to exhibit and help sponsor in 2026. The company positions itself as a green, research-backed alternative to conventional chemical water treatment, with a mission summarized on its website as "Making Water Healthy for All."

Greenwater Services is a water treatment company that has developed and commercialized a patented NanoBubble Ozone Technology (NBOT) platform. The company's public history is primarily documented through its own website and a Wikidata entry. It is owned by the J.J. Cafaro Investment Trust, an entity associated with the Cafaro family, a prominent business family in the United States known for shopping mall development. The company operates from the United States and focuses on water remediation projects across the country. Greenwater Services states that its NBOT system is the only water purification system in the world whose patented technology is backed by both government and academic research. The technology was developed to address harmful algal blooms (HABs), which have become a growing environmental challenge in freshwater and marine systems across the United States. The company reports that its system has been successfully applied in various locations, including the Lock at Port Mayaca in Florida, Lake Sylvan, and lakes in Ohio, resulting in significant improvements in water quality and visual clarity. The company's approach is centered on a chemical-free process that uses ozone infused into nano-bubbles. These nano-bubbles are buoyantly neutral, meaning they do not rise to the surface, allowing for an ozone absorption rate of 95–98% and comprehensive treatment throughout the water column. The process generates hydroxyl radicals, which the company claims are over 20,000 times stronger than chlorine, to oxidize and destroy organic compounds. The only by-product is oxygen, which also increases dissolved oxygen levels beneficial to aquatic life. Greenwater Services offers a range of products and services, including portable and permanent NBOT installations, ozone generators, nano-bubble diffusers, and water quality sensors. It also provides consulting, customized solution design, and project management. The company targets agriculture, data centers, government agencies, and municipalities. It continues to engage with the scientific and environmental community, for example by participating in the 13th U.S. Symposium on Harmful Algae in 2026. As of the available evidence, the company remains active and privately held.
