Dog Deaths Raise Algal Bloom Alarm As States Report More Toxins

/in , /by /Bloomberg Environmentby Alex Ebert and Stephen Joyce

A high-profile series of dog deaths has awakened the public to the growing problem of toxic algal blooms, spurred by rising temperatures and pollution.

The blooms are emerging as a national, not just regional, concern, according to preliminary data reported to the U.S. Environmental Protection Agency through July. Samples taken from New Jersey to California, and from Texas to Washington state, all show evidence of toxins given off by the blooms.

Since 2018, when the EPA started collecting the latest batch of data, algal blooms have been documented near the intakes of water treatment plants at least 130 times.

City Links Golf Course To Recycled Water

/in , /by /The Sun - Gazzete by Reggie Ellis

As the deadline for groundwater sustainability approaches in California, one Tulare County city has taken another step toward eliminating its need for landscape irrigation.

At its Aug. 19 meeting, the Visalia City Council approved a notice of completion to replumb the waterlines used to irrigate the Valley Oaks Golf Course to carry recycled water instead of groundwater. The project installed 2-inch potable water lines and 8-inch irrigation lines at four locations throughout the golf course, with backflow preventers and water elevation sensors to separate drinking water from mixing with irrigation water.

How California Wildfires Can Impact Water Availability

/in , , /by /Phys.Orgby Julie Chao

In recent years, wildfires in the western United States have occurred with increasing frequency and scale. Climate change scenarios in California predict prolonged periods of drought with potential for conditions even more amenable to wildfires. The Sierra Nevada Mountains provide up to 70% of the state’s water resources, yet there is little known on how wildfires will impact water resources in the future.

How Much Water Do Plants Need?

/in , /by

It’s important to assess how much water your outdoor plants need to stay healthy. The heat and humidity in San Diego County is far from over, with the official start of Fall September 23. Irrigation needs are generally highest during these warm months.

Did you know that plants can be classified by their water needs?

Landscaping professionals use a resource called the Water Use Classification of Landscape Species, or WUCOLS, to classify plants according how much water they need to thrive.

It might sound complex, but it’s very useful because it breaks down the water requirements for each type of plant. There are four categories: Very Low, Low, Moderate, and High. These water requirements are also called Plant Factors. They are an important tool for transitioning to a more water-efficient landscape. By knowing exactly how much water your plants need, you can cut down on your water usage while also keeping your plants happy.

Calculating water requirements for outdoor plants

To calculate a Plant Factor, compare the plant’s water use to cool season grass in a given climate zone.

Why is that? Turf is among the thirstiest of all types of plants. When you replace turf areas with climate-appropriate plants with lower water requirements, and irrigate them with more efficient systems, you can greatly increase your water efficiency. You don’t have to turn your landscaping into a dry moonscape to do it.

Plant factors, or PF, categories:

Plant Factor categories from high to low water use. Graphic: Water Authority

High: Plants need from 60 to 100 percent of the water needed for a grass lawn (PF of 0.6 – 1.0)

Moderate: Plants need 30 to 60 percent of the water needed for a grass lawn (PF of 0.3 – 0.6)

Low: Plants need 10 to 30 percent of the water needed for a grass lawn (PF of 0.1 – 0.3)

Very Low: Plants need 10 percent or less of the water needed for a grass lawn (PF of less than 0.1)

Group plants by PF to irrigate more efficiently

In the Water Authority’s Sustainable Landscaping guidebook, plant selections are color-coded to identify their water needs under this system. That approach provides an easy way to group plants by their water requirements in your landscape, so you can irrigate more efficiently.

This article was inspired by the 71-page Sustainable Landscapes Program guidebook available at SustainableLandscapesSD.org. The Water Authority and its partners also offer other great resources for landscaping upgrades, including free WaterSmart classes at WaterSmartSD.org.

How-To Replace Your Turf And Get Paid

Did you know that outside landscaping consumes around 50-70 percent of water used at a single property? Not only does that take precious resources, but it also costs you, the homeowner, money. You may qualify for a rebate program that pays to save! Elsinore Valley Municipal Water District and the Metropolitan Water District of Southern California are offering a rebate program for removing grass turf and replacing it with a water-wise yard.

Crystalline Nets Harvest Water From Desert Air, Turn Carbon Dioxide Into Liquid Fuel

When Omar Yaghi was growing up in Jordan, outside of Amman, his neighborhood received water for only about 5 hours once every 2 weeks. If Yaghi wasn’t up at dawn to turn on the spigots to store water, his family, their cow, and their garden had to go without. At a meeting last week here, in an-other area thirsting for freshwater, Yaghi, a chemist at the University of California, Berkeley, reported that he and his colleagues have created a solar-powered device that could provide water for millions in water-stressed regions.

Senate Bill 1 Continues To Move Through The California Legislature

Last week California Senate Bill 1 (SB 1) continued with its forward momentum, advancing from the California Assembly Appropriations Committee by a vote of 13 to five.  The legislation that some environmental groups are referring to as ‘Trump insurance’ is now headed to the California Assembly floor.  The California Environmental, Public Health, and Workers Defense Act of 2019 known as SB 1 seeks to uphold specific federal policy as it pertains to water.

Proposed EPA Rules Could Limit State And Tribal Power To Block Infrastructure Projects

/in , /by /KLCC (Eugene, Ore.)by Jes Burns

The Trump administration is proposing new rules that would limit state and tribal power to block projects that they deem harmful to water quality.

The rules specifically would restrict these non-federal governments’ authority to review the water quality impacts of projects that require a federal permit or license. These projects range from pipelines to hydropower facilities to dredging — any development that result in “discharge” into U.S. waters.

Under the Clean Water Act, states have the power to regulate water quality within their borders. In Oregon, that authority falls to the Department of Environmental Quality.

Hydropower Giant Bonneville Power Is Going Broke

/in , /by /E&E Newsby Jeremy P. Jacobs

Nearly a century ago, America embarked on a great social experiment in the Pacific Northwest, charging up the Columbia River and erecting dams.

It worked. Construction jobs pulled the country out of the Great Depression. Cheap electricity spurred the growth of cities like Seattle, Portland and Boise. And hydropower fueled the military effort to defeat the spread of fascism in World War II.

Now the system is buckling.

The Bonneville Power Administration, the independent federal agency that sells the electricity produced by the dams, is careening toward a financial cliff.

The calendar has flipped to September, but Sacramento is still experiencing August heat.

Following a Labor Day high of 98 degrees, the latest National Weather Service forecasts show a slight cool-down on the way. Tuesday and Wednesday are expected to hit 96 and 95 degrees, respectively, before temperatures cool to the low 90s or high 80s by the end of the week.

The Delta breeze will help bring nighttime relief, with low temperatures expected in the low- to mid-60s through Friday.
