Impacts of the 2014 severe drought on the Microcystis bloom in San Francisco Estuary

Harmful Algae (Elsevier) | February 17th, 2017

Summary

The increased frequency and intensity of drought with climate change may cause an increase in the magnitude and toxicity of freshwater cyanobacteria harmful algal blooms

The increased frequency and intensity of drought with climate change may cause an increase in the magnitude and toxicity of freshwater cyanobacteria harmful algal blooms (CHABs), including Microcystis blooms, in San Francisco Estuary, California. As the fourth driest year on record in San Francisco Estuary, the 2014 drought provided an opportunity to directly test the impact of severe drought on cyanobacteria blooms in SFE. A field sampling program was conducted between July and December 2014 to sample a suite of physical, chemical, and biological variables at 10 stations in the freshwater and brackish reaches of the estuary. The 2014 Microcystis bloom had the highest biomass and toxin concentration, earliest initiation, and the longest duration, since the blooms began in 1999. Median chlorophyll a concentration increased by 9 and 12 times over previous dry and wet years, respectively. Total microcystin concentration also exceeded that in previous dry and wet years by a factor of 11 and 65, respectively. Cell abundance determined by quantitative PCR indicated the bloom contained multiple potentially toxic cyanobacteria species, toxic Microcystis and relatively high total cyanobacteria abundance. The bloom was associated with extreme nutrient concentrations, including a 20-year high in soluble reactive phosphorus concentration and low to below detection levels of ammonium. Stable isotope analysis suggested the bloom varied with both inorganic and organic nutrient concentration, and used ammonium as the primary nitrogen source. Water temperature was a primary controlling factor for the bloom and was positively correlated with the increase in both total and toxic Microcystis abundance. In addition, the early initiation and persistence of warm water temperature coincided with the increased intensity and duration of the Microcystis bloom from the usual 3 to 4 months to 8 months. Long residence time was also a primary factor controlling the magnitude and persistence of the bloom, and was created by a 66% to 85% reduction in both the water inflow and diversion of water for agriculture during the summer. We concluded that severe drought conditions can lead to a significant increase in the abundance of Microcystis and other cyanobacteria, as well as their associated toxins.

Implementing a Public Goods Charge for Water

California Public Utilities Commission (CPUC) | July 12th, 2010

Summary

Our client asked for recommendations on how to implement a public goods charge (PGC) on water, as per the “Water Energy” section of the Assembly Bill 32 (AB 32) Scopi

Our client asked for recommendations on how to implement a public goods charge (PGC) on water, as per the “Water Energy” section of the Assembly Bill 32 (AB 32) Scoping Plan. Before considering “how,” we considered whether a public goods charge for water is the right tool. The problem we wanted to address is the negative externalities of high water consumption, including greenhouse gas emissions from the energy used to pump, transport, treat, and heat water. We gave serious consideration to two alternate strategies but ultimately decided the public goods charge for water is the best tool. We recommend a public goods charge for water because: A public goods charge for water creates a price signal for water conservation. A public goods charge for water would provide a stable, sustainable funding mechanism to support the full list of conservation and efficiency activities specified in Assembly Bill 32. The dual energy and water conservation programs specified in AB 32, which could not be fully funded through the other mechanisms we considered, will be effective to both mitigate and adapt to climate change. Our proposed implementation strategy will help institutionalize regional water agencies, which are necessary for the state’s long?term water?planning effectiveness. We then make specific recommendations about the design of the public goods charge: We recommend passing state legislation requiring all water providers to assess volumetric surcharges on each water bill where metered, or by alternate means in the short?term for areas not metered. We recommend that the funds be managed by regional joint power authorities to implement Integrated Regional Water Management Plans (IRWMPs), which must institutionalize their operating structure before this can be put in place. This will provide the necessary regional organization for effective project choices, and will reduce the number of water agencies that need oversight from thousands to 50. We recommend that the Department of Water Resources (DWR), which already has jurisdiction over the IRWMPS, provide direction and oversight to ensure that specified state goals are met and that funds are well?managed, with assistance from the WETCAT members. We recommend that the fees initially be set to raise $680 Million per year. That level of funding can be used to meet the water supply targets of Senate Bill X7?7, and to exceed the greenhouse gas emissions goals of Assembly Bill 32. We recommend that the legislation be structured with maximum flexibility to allow for future rate changes.
