Every drop of rain that falls on the landscape has several possible destinations. Some water evaporates back into the atmosphere. Some is absorbed by plants and later released through transpiration. Some flows across the land as stormwater runoff into ditches, streams, rivers, and lakes. Another por…

When stormwater professionals encounter an unexplained discharge, a suspicious pipe, or a drainage system that does not behave as expected, one of the most effective investigative tools available is dye testing. Used by municipalities, engineers, environmental consultants, utility operators, and reg…

One of the greatest challenges facing municipal stormwater programs is finding meaningful ways to engage residents in protecting local waterways. Public education campaigns are important, but brochures, websites, and social media posts often struggle to create lasting behavioral change. People are f…

The Adirondack Watershed Institute, often referred to as AWI, has become one of the most important environmental organizations working to protect New York’s lakes, rivers, and wetlands. Based at Paul Smith’s College in the northern Adirondacks, AWI blends scientific research, on-the-grou…

Floating wetlands are emerging as an innovative and increasingly popular tool for improving water quality in stormwater systems, ponds, and urban waterways. By replicating many of the functions of natural wetlands without requiring extensive excavation or shoreline restoration, these systems offer m…

When most people think about stormwater pollution, they think of sediment, nutrients, oils, trash, or road salt. However, heat itself can be a pollutant. Thermal pollution occurs when stormwater runoff becomes significantly warmer than the natural receiving waters it eventually enters. Elevated wate…

Most storm drain inlets quietly collect and convey runoff without attracting much attention from the public. To many residents, a storm drain is simply another opening in the curb or grate in the pavement. What many people do not realize, however, is that storm drains in most municipalities discharg…

Stormwater runoff can cause fish kills through a combination of physical, chemical, and biological mechanisms that alter aquatic environments beyond the tolerance limits of fish and other aquatic organisms. These impacts are often rapid, episodic, and closely tied to precipitation events, especially…

Street sweeping rarely gets much attention. It is slow, repetitive work, often done in the early morning hours, and the equipment itself can be temperamental and expensive to maintain. Sweepers are subject to constant wear, from abrasive debris, dust, and the mechanical strain of brushes, conveyors,…

Fire hydrant flushing is a common and often necessary practice for maintaining water distribution systems. Municipalities flush hydrants to remove sediment, verify system performance, and ensure adequate flow for firefighting. While these objectives are important, the practice can carry a range of u…

Understanding Natural vs. Problematic Foam in Streams, Channels, and Lakes If you spend enough time around streams, roadside ditches, or lakes, you will eventually notice patches of foam collecting along the edges or drifting in slow-moving water. For many people, the immediate assumption is that th…

For decades, the ideal suburban yard has been defined by a single image, a uniform carpet of bright green grass, edged with ornamental shrubs and kept pristine through fertilizers, pesticides, and frequent watering. It is neat, predictable, and widely accepted as a symbol of care and success. But fr…
