About Clean Streams, Rivers and Lakes

A Virginia Nonprofit 501(c)(3) Charity

Who We Are

Clean Streams, Rivers and Lakes is a Virginia Nonprofit 501(c)(3) charity, effective January 2021. Our mission is to research, educate, engineer, manufacture, remediate, and perform all activities needed to achieve safer, cleaner water quality on our planet Earth.

We are led by Matthew J. Rainoff, President/Treasurer, with Jeffrey C. Stahle as Secretary and Mark L. Tull as Vice President. Together, our board of directors has over 120 years of business operation experience!

How We Clean Water Without Toxic Chemicals

Whenever possible, we use aeration, beneficial bacteria in ceramic carriers, a patented diatom promoter, and mined granular calcium silicate. All of our water treatment programs use only non‑toxic, safe‑to‑handle components.

• Bio‑remediation to break down excess nutrients
• Diatom blooms to outcompete nuisance algae
• PhosClear - Buffered Aluminum Sulphate and EutroSORB WC lanthanum based treatments to bind and reduce phosphorus
• Aeration to improve dissolved oxygen, accelerate Beneficial Bacteria growth, mix water column, and ecosystem health

These natural methods reduce nitrogen and phosphorus, improve clarity, reduce odor, and support long‑term restoration.

When Herbicides Are Necessary

When exotic or troublesome weeds must be removed, we use the highest‑quality, shortest‑life aquatic herbicides available—and only when necessary. We are licensed by the Commonwealth of Virginia: Pesticide Business License #15812.

Experience Behind the Mission

Clean Streams, Rivers and Lakes is run by Matthew Rainoff, who has over 30 years of scientific experience designing, integrating, and supporting cost‑effective solutions for nonprofits, governments, commercial clients, and individuals.

Today, Matt focuses on natural nutrient‑removal techniques to restore water quality. Our suppliers’ PhDs, biologists, and scientists support every aspect of design, technical development, and product engineering.

From Studying the Problem to Taking Action

The time for endless studies of excess nutrients—water pollution—has passed. It is time for safe, actionable plans.

We have working plans to treat and prevent hazardous algae blooms, cyanobacteria, clarity issues, and other water problems at reasonable costs, while also improving oxygen and helping offset carbon issues as water becomes healthier.
