Life in Plastic: California Charges Ahead

,

California is blazing new environmental trails again. The State is set to become the first government in the world to issue a standard testing methodology and preliminary health assessment for microplastics in drinking water. The guidelines, originally scheduled for release this month but delayed due to the pandemic, will be published during the fall of 2021. There is considerable interest in the State Water Board’s (SWB’s) upcoming report, both within the water industry and the broader public. With plastic creeping into every facet of modern life, the SWB’s conclusions will likely lay the foundations for further research and policies.

Since the creation of the first synthetic ivory in 1869, plastic has become the invisible backbone of the modern world. Synthetic materials often serve as cheaper, more durable substitutes for rare and expensive natural resources like silk, ivory, and wood. Plastic production also facilitates many modern inventions and comforts, such as…

Pyrethroids—Gardeners Best Friend Versus Fishy Foe

, , ,

Spring is underway, and across California, gardeners and farmers are combating the season’s annual pest problem: insects. But the pesticides that protect our roses and our lettuce may be harming more than just the bugs. Pesticides, in particular pyrethroids, are making their way from our gardens, farms, and houses into our watersheds, where they pose a serious threat to California’s aquatic populations. With annual pesticide use expected to peak in the coming months, now is the time to ask some questions. What are pyrethroids? How are they impacting our water systems? What is being done to mitigate the potential problems associated with their use?

Since the late 19th century, pyrethroids have been around and are similar to some naturally occurring insecticides, called pyrethrins, found in chrysanthemum flowers. But unlike pyrethrins, pyrethroids are manufactured chemicals designed to quickly incapacitate insect nervous systems and simultaneously resist environmental degradation. Their low toxicity to humans, mammals, and birds makes them ideal for a variety of agricultural, public health, and domestic purposes. Pyrethroid compounds are effective insecticides employed on farms and in homes across the US. In particular, pyrethroids are an efficient…

Portantino Leads Effort to Manage CECs in CA

, , ,

Over the last decade, advancements in analytical testing technologies have revealed new categories of previously undetectable substances now dubbed as CECs—Constituents of Emerging Concern. This ever broadening group of chemicals and microorganisms pose unprecedented technical, legal, and financial challenges; but arguably, the biggest hurdle is the lack of available information about the persistence, prevalence, or toxicity of many substances referred to as CECs. In an effort to fill those data gaps, Senator Portantino introduced Senate Bill Number 230 (SB 230) to California’s State legislature this year. The bill, which seems to enjoy wide support from water agencies, would mark the first state-wide effort to address CECs as a category.

While information has grown over the past few years, most research has focused on high-profile chemicals or chemical families. This is partially because CECs are such an immense and diverse category; any new or newly detected and unregulated substance found in California’s waters is considered a CEC. This broad definition encompasses thousands of …
