Foam in Waterways

Thu, 09/14/2023 - 09:52

Where is the foam from?

It is common for organic matter naturally found in our waterways to decompose, releasing fatty molecules (lipids) that produce the foam we see on the surface of the water. This happens every year, usually during the spring runoff season, but it can also occur during periods of high precipitation and high temperatures in summer and fall months. The foam is most apparent at locations where the water is naturally agitated by flowing over rocks or discharging from pipes. The foam produced may be more than a foot deep!

It’s Time to Talk About Dog Poop

Thu, 02/25/2021 - 15:58

In the United States, pet dogs produce 21.2 billion pounds of poop each year. All that poop is polluting water sources, both in urban areas and the backcountry, largely because dog owners aren’t doing a good enough job picking it up. Let’s look at the reasons why dog poop has become such a problem, and examine what we can do about it.

Why Dog Poop Matters

Research shows that most dog owners pick up after their pets in the street and at the local park, but often don’t take along a plastic bag when out hiking in the backcountry, assuming it’s no big deal. But Wes Siler, a contributing editor to Outside Magazine, tells host Steve Curwood that all that dog poop does add up to potential harm by introducing foreign bacteria and nutrients to forests, fields, and streams.

Satellite images of rivers across the U.S. have revealed a troubling color-changing trend: Over the past three decades, one-third of formerly blue rivers have turned a shade of yellow or green. The discovery comes after an analysis of nearly 235,000 images taken from 1984 to 2018. Amongst the rivers that changed color, 56 percent were mostly yellow and 38 percent were mostly green.

Water-Saving Technology You Should Care About

Mon, 09/28/2020 - 10:32

Did you know 70% of the Earth’s surface is covered with water, but only 1% of that is available for humans to use?

The pace of our global society is moving too fast for water to fulfill its potential as a renewable resource. We have made fresh water into a finite resource. Water resources, like groundwater, are being depleted because they aren’t able to recharge at the same rate of our growing population and increased agricultural activity. Basically, we consume water at a highly unsustainable and concerning rate.

Q.  How much water do landscapes use in California?
A.  Landscape irrigation accounts for only about 9% of total statewide developed water use, but the percentage varies widely among communities.  Water applied to landscapes is estimated to account for about 50% of residential water consumption statewide, but the amount varies from about 30% in some coastal communities to 60% or more in many inland suburban communities.
