Phosphorus is the second-most-regulated pollutant in stormwater runoff after total suspended solids. However, engineers and regulators are still learning how to

As we return to work after the Christmas break, we can’t help but look forward to 2023 and what the future holds for stormwater management. We reached out to several Contech associates to get their insight. Here is what they had to say.

Public parks benefit the community by providing places for recreation, gathering, education, and relaxation. Often, they provide benefits in the form of

Bioretention has been the principal form of Low-Impact Development (LID) used to slow, treat, retain and infiltrate stormwater runoff, mimicking a site's natural, pre-development hydrology. One aspect of bioretention that has some scientists and regulators concerned is the phenomenon known as nutrient leaching. Nutrient leaching occurs when the bioretention media, which often contains compost, breaks down and releases phosphorus to downstream receiving waters.

It's hard to believe, but it has been almost twenty years since Filterra bioretention was introduced as a high-flow stormwater treatment system. For those that
