A new study conducted by Penn State’s College of Agricultural Sciences showed that shallow disk injection compared to the surface broadcast of manure into the soil considerably lowered estrogen in biosolids runoff. The former biosolids application method may be an effective strategy in controlling the mobilization of estrogen thereby significantly improving downstream water quality. The […]

Nitrogen exists in many forms in the environment and can enter aquatic systems from fertilizer run-off and wastewater discharges. Treated domestic sewage sludge will have varying levels of nitrogen, depending on the method of treatment used. Most treatment plants decrease the level of total nitrogen in sewage sludge via cell synthesis and solids removal. However, […]

One of the more difficult challenges facing waste management in water treatment is the removal of fat aggregations or fatbergs. Fatbergs are congealed lumps of fat that come from a variety of sources which then bind to other wastes that do not degrade in water such as sanitary napkins, wet wipes, condoms, and diapers to […]

Plastic has been one of the most significant inventions ever developed because of its versatility and relatively low cost in production. You will see it in used in almost every facet of life since the 1950s, but one growing concern is the contamination of microscopic plastic fibres that have only been recently discovered in our […]

Barcelona has over 1500 km of sewage passageways traversing beneath the city and inspecting it can be a very daunting task. The tunnels in the system are very narrow and vary in size. They are also slippery, not well lit, and often contain pungent gases. FCC, a Madrid-based company, has pioneered a project that could […]

There has been a renewed commitment between the US and Canada to reduce nitrate and phosphorous loading into the Great Lakes River Basin and maintain soil nutrients levels through the Great Lakes Water Quality Agreement. Conservation Authorities (CAs) have been set up in Ontario to act as the primary mover in watershed management programs. They’ve […]

Water is one of the most important elements for life and its role in shaping Canada cannot be overlooked. Whether in the form of ice, snow, rivers, or lakes, water has had a huge impact on Canada’s identity. In celebrating its 150th anniversary, Canada needs to find a new perspective in treating this valuable resource, […]

A new research study published by the Canadian Journal of Fisheries and Aquatic Sciences investigated the phosphorus loading in Canadian fresh waters. It aimed to understand the geographic patterns and environmental drivers of this vital process in aquatic ecosystems. The journal’s article “Internal Phosphorus Loading in Canadian Fresh Waters: A Critical Review and Data Analysis” […]

Historically, wastewater has been regarded as a human health risk and environmental hazard, but a shift in current attitudes now values wastewater as a potential source of recyclable materials and energy. It plays an important role in recovering resources that are becoming increasingly scarce. Wastewater contains tissue paper fibers and this material can be harvested […]

The Great Lakes are an important and vulnerable resource that supplies safe, potable drinking water, which promotes better quality of life and economic prosperity. Ontario collaborates with government and community stakeholders to preserve the Great Lakes’ water quality and ecosystems. In 2014, the new Canada-Ontario Agreement (COA) identified 5 major priorities, which includes the following: […]
