Wineries: don’t waste the wastewater

The recycling of wastewater at large-scale production facilities such as wineries is considered by some to be a sustainable and innovative response to the harsh climate and water shortages many areas are currently facing. However, the question of what impact this wastewater will have on both the facilities and the surrounding environment is still up for debate. Recent research has investigated the effect that irrigating vineyards with wastewater has on the crops, the soil, and the wine produced by several wineries in California.

Wastewater and wetlands: a friendship for the ages?

Today’s wastewater is not what it once was. Pharmaceuticals, personal care products, and other lifestyle products are contributing compounds to wastewater that have emerged as harmful contaminants in the environment. In order to combat these contaminants, which are not being effectively treated by conventional wastewater treatment plants, some places have incorporated constructed wetlands as an additional treatment method meant to eliminate emerging contaminants before they enter into the environment.

Rejuvenating Agricultural Soils

Soils play an important role in the global carbon cycle because they can absorb carbon from and emit carbon into the atmosphere. Currently, agricultural soils are not home to very large carbon pools. Recent research investigated the effects of adding carbonized crop residue to soils in agricultural environments in the hopes of finding ways to increase the amount of carbon retained by these soils.

The fate of our waste: nitrogen removal in residential wastewater

Residential wastewater serves as a major source of nitrogen to coastal watersheds. Increased nitrogen loads can harm coastal ecosystems, so advanced onsite wastewater treatment systems have been designed in order to reduce these loads and protect coastal waters.
