A new tool from the International Hydropower Association draws on data from 18 international studies to help developers and others improve sediment management in waterways. The Hydropower Sediment Management Knowledge Hub was developed in partnership with the South Asia Water Initiative, which brings together the World Bank and the governments of Australia, Norway and the UK.
A three-year study of Georgia's Lake Lanier will assess the environmental effect of septic systems. Georgia Tech Research Corp. will carry out the work with others under a Gwinnett County contract, sampling and monitoring groundwater quality and flow, as well as lake water and sediment, in developed and undeveloped areas around the lake.
Action to address algae blooms on California's Lake San Marcos will be in the offing after authorities test the effectiveness of various methods. The problem stems from nitrogen and phosphorous runoff that feeds into San Marcos Creek, which was dammed in 1946 to create the lake.
A standard way to gauge soil health is the first step in a concentrated effort by the Foundation for Food and Agriculture Research to address the rapidly growing loss of the world's topsoil. The foundation is directing $20 million for the effort to three partners -- The Nature Conservancy, the Soil Health Institute and the Soil Health Partnership -- with much of the work to be done in Indiana.
While remaining critical of an Obama-era rule requiring the Environmental Protection Agency to regulate greenhouse gases, current EPA chief Scott Pruitt said the agency will formulate a new rule rather than simply killing the old one. Utilities have been pressing for a less ambitious rule rather than the uncertainty of having no regulation at all.
Attend the last webinar of the year on Dec. 13 to understand the importance of soil health. Poor soil health reduces food production, decreases water quality and increases soil erosion problems. The effects can be lessened or eliminated with the adoption of soil health BMPs which improves the health of the soil. Register now.
Some drivers were upset with the price of dynamic tolling on new express lanes on Interstate 66 in Virginia, but the editorial board at The Washington Post argues that the lanes are altering drivers' behavior and thus doing their job. The lanes help reduce congestion and encourage carpooling and the use of public transportation.
The tolled express lanes on Interstate 580 between Dublin and Livermore in the San Francisco area earned in excess of $9 million in revenue in their first year of operation and have become the leading express lanes in the region. Between October 2016 and October 2017, more than 7.9 million vehicles used the lanes -- more than used other express lanes.
The Virginia Department of Transportation says tolling charges for using the new Interstate 66 express lanes will appear on statements several days after drivers use the lanes. The agency is double-checking charges, making sure drivers are accurately billed, and it says motorists can file complaints if their bills are incorrect.
The government in Indonesia is converting toll roads into open-road tolling, but it has not decided what system to purchase for the final phase. The country hopes to have all-electronic tolling in place by the end of 2018.
