While water chestnut would literally take over the river from shore to shore, the Mystic River Watershed Association and many partners battled the invasive plant with the help of mechanical harvesters and by organizing volunteer hand-pulling events. Water chestnut (Trapa natans) is native to Asia, Europe and Africa. It was introduced in 1897 by a
New summer, same problem. The weeds in Lake Hopatcong in New Jersey are back and, according to at least one aquatic and watershed management expert, are “some of the worst” in recent memory. Fred Lubnow, director of aquatics programs at Princeton Hydro, has been studying the lake for more than 20 years. He said in
Bioengineering is defined by the Michigan Department of Environmental Quality as “using a combination of native planting and natural, or biodegradable materials to provide shoreline protection.” It also is often referred to as softshore engineering or lakescaping. Many shorelines use seawalls. These are a hard surface, such as wood, metal or concrete, that is installed
Hydrilla and water hyacinth, two of the worst aquatic weeds, have taken over the surface of Tapi River in India just above the pumping stations. This phenomenon of summer, which creates problems in the pumping of water from the pumping stations to Surat city, has occurred this time of the year for the first time.
Heavy metal poisoning is a growing concern in many parts of the country. A new method for removing chromium-6, a highly toxic heavy metal, from waste water has been developed by a group of scientists from India and Ethiopia. They claim it to be low-cost and safe. The new method uses water hyacinth, a weed
Nearly 95% of Malawi’s power is generated by hydropower on the Shire River, but sedimentation and weed infestation hinder efficiency. Today Millennium Challenge Corp Principal Deputy Vice President Kyeh Kim joined U.S. Embassy Lilongwe Ambassador Virginia Palmer to celebrate the commissioning and hand-over of two new weed harvesters by MCA-Malawi to the Electricity Generation Company
