Commercial aquatic plants grown in constructed wetlands (CWs) are being touted as inexpensive, low-technology approaches for treating agricultural, industrial, and municipal wastewater to comply with increasingly stringent environmental regulations.
CWs, or marshes built to treat contaminated water, incorporate soil and drainage materials, water, plants, and microorganisms.
Aquatic Plants Determine Ocean Health
Research at the Department of Civil and Environmental Engineering of MIT suggests that aquatic plants in rivers and streams may play a vital role in the health of oceans and coastal waters.

More effective for greenhouse and nursery operations with limited production space and expensive land are a type of constructed wetland called "subsurface flow".
Subsurface flow wetlands consist of a lined or impermeable basin filled with a coarse medium, typically gravel, and wetland plants.
Finland Town Under Health Crisis Following Water Contamination
Hundreds of people in the Finnish town of Nokia have fallen ill with diarrhoea and vomiting after a worker at a sewage plant mistakenly contaminated the water supply, city officials said Friday.

Robert Polomski and his colleagues at Clemson University investigated the nitrogen and phosphorus removal potential by a vegetated, laboratory-scale subsurface flow system.

Prions are a Threat to Vegetarians too
Infectious prions, the causative agents in mad cow disease and human vCJD can survive wastewater decontamination and potentially contaminate fruit and vegetables.

Over an eight-week period, five commercially available aquatic garden plants received a range of nitrogen and phosphorus that spanned the rates detected in nursery runoff.

Urine Purification to Revolutionize Waste Water Management
Recent research has revelaed that it is better to collect and purify urine separately, rather than simply allowing it to flow into the sewer, from an environmental and cost perspective.

Although more research is necessary to address other variables, the study concluded that the use of commercially produced plants in constructed wetlands has the potential to generate revenue for producers.
