May is American Wetlands Month!

The Environmental Protection Agency (EPA) has deemed May American Wetlands Month, drawing attention to the significant impact wetlands have on our nation’s ecological, economic, and social health. By definition, a wetland is just what it sounds like: an area saturated by water. This type of land is commonly referred to as a marsh or bog. The EPA points out that wetlands are “areas where water covers the soil” for either varying periods of time, or throughout the entire year. Wetlands affect many of the things we may take for granted: they improve water quality; increase water storage and supply; reduce flooding; and provide habitats for plants, fish, and wildlife.

In addition, wetlands can be engineered to treat wastewater, which is called a Constructed Treatment Wetland or CTW. Here at Roux Associates, CTWs are a large part of our patented Engineered Natural Systems (ENS®) technologies. Our systems have been approved by both state and regulatory agencies, including the EPA and the US Army Corps of Engineers.

Roux has been actively involved in developing and applying CTW technologies since 1993. We are internationally recognized experts and leaders in the design, installation, and operation of CTWs. Our award-winning ENS® Group focuses on the application of these technologies to treat groundwater and surface water contamination, stormwater runoff, landfill leachate, and industrial/municipal wastewaters. Our use of carefully selected media, sequencing, and passive hydraulic controls has resulted in state-of-the-science designs that are cost‑effective, reliable, and sustainable—even under extreme environmental conditions. Roux’s ENS® designs operate passively, require little to no power, and thus reduce operation and maintenance requirements and costs. Our company has applied these technologies to tackle some of industries’ most challenging environmental issues, while achieving sustainable goals, such as water reuse and zero discharge.

Nitrogen Pollution: Impacts and Solutions

Nitrogen pollution is a major environmental and public health issue for Long Island, NY. A leading cause of nitrogen pollution in groundwater and surface water is the large number of cesspools and septic systems in Suffolk County. These systems do not remove nitrates from sanitary waste, allowing nitrates to leach into aquifers and eventually into surrounding estuaries and bays. Nitrogen pollution results in many negative complications which impact Long Island’s resiliency to storms, ecosystem health, and the economy. Negative impacts of nitrogen pollution include:

  • Contamination of drinking water.
  • Erosion of shorelines and destruction of wetlands.
  • Decline in seagrass beds.
  • Declines in shellfish and commercial fishing.
  • Recreational use limitations in estuaries and bays.
  • Algal blooms that (1) produce neurotoxins causing turtle mortality, and (2) consume oxygen from the water (i.e. Hypoxia) resulting in fish kills. Evidence of this has been prevalent in the Peconic River and Flanders Bay region of the Peconic Estuary.

“Long Island Sees a Crisis as it Floats to the Surface”

How we may address the nitrogen pollution problem will be discussed at the Long Island Water Quality Forum, to be held on June 23rd from 8:00am-11:00am at the Charles B. Wang Center, Stony Brook University. The forum, sponsored by the New York League of Conservation Voters Education Fund, Stony Brook University and Roux Associates, will examine technological solutions to nitrogen pollution and discuss proposals to fund these upgrades.

Principal Scientist, Amanda Ludlow of Roux Associates, will be a panelist at the forum and will be discussing Constructed Treatment Wetlands as a tool to confront nitrogen pollution; a community based natural system approach.
