What Can We Learn From How the State Responded to the Last Major Drought?

For the second consecutive year, the state is experiencing extremely low rates of precipitation. As we prepare for what could be an extended period of dry conditions, it is helpful to review how the state responded to the last major drought. Such information can inform—and thereby potentially improve—the state’s current and ongoing response to developing … Continue reading “What Can We Learn From How the State Responded to the Last Major Drought?”

Anthropogenic Stressors and Changes in the Clear Lake Ecosystem as Recorded in Sediment Cores

Sediment cores were collected to investigate multiple stresses on Clear Lake, California, USA, through the period of European occupation to the present day. Earlier workers suggested the hypothesis that the use of mechanized earthmoving equipment, starting in the 1920s and 1930s, was responsible for erosion, mercury (Hg) contamination, and habitat loss stresses. Cores (;2.5 m in depth) were collected … Continue reading “Anthropogenic Stressors and Changes in the Clear Lake Ecosystem as Recorded in Sediment Cores”

Mercury in Abiotic Matrices of Clear Lake, California: Human Health and Ecotoxicological Implications

Mercury (Hg) from Hg mining at Clear Lake, California, USA, has contaminated water and sediments for over 130 years and has the potential to affect human and environmental health. With total mercury (TotHg) concentrations up to 438 mg/kg (dry mass) in surficial sediments and up to 399 ng/L in lake water, Clear Lake is one of the most Hg-contaminated … Continue reading “Mercury in Abiotic Matrices of Clear Lake, California: Human Health and Ecotoxicological Implications”

Pilot Study of Contaminants of Emerging Concern (CECs) in the Russian River Watershed: Lessons Learned

Contaminants of emerging concern (CECs) can be defined as any chemicals that are not regulated or commonly monitored but have the potential to enter the environment and cause adverse ecological or human health impacts. Determining which of the thousands of chemicals in commerce are CECs and whether or not they may be a problem is … Continue reading “Pilot Study of Contaminants of Emerging Concern (CECs) in the Russian River Watershed: Lessons Learned”

Learning from California’s Experience with Small Water System Consolidations: A Workshop Synthesis

California recognizes a human right to “safe, clean, affordable, and accessible water adequate for human consumption, cooking, and sanitary purposes.” However, California’s small and disadvantaged communities in both rural and urban contexts can find it especially challenging to fund the water system infrastructure, operations, monitoring, and maintenance necessary to achieve this goal.  Small water systems … Continue reading “Learning from California’s Experience with Small Water System Consolidations: A Workshop Synthesis”

Synthesizing Conservation Motivations and Barriers: What Have We Learned from Qualitative Studies of Farmers’ Behaviors in the United States?

Since 2011, qualitative studies examining adoption of conservation practices and programs (CPPs) have burgeoned. This article presents a systematic review of all U.S.-based qualitative investigations into CPP adoption since 1996. We found three themes are discussed primarily as motivating adoption: farmer characteristics, environmental awareness, and trust in information sources. Four themes are discussed primarily as … Continue reading “Synthesizing Conservation Motivations and Barriers: What Have We Learned from Qualitative Studies of Farmers’ Behaviors in the United States?”
