State Results Show High Levels Of Lead In Water At Various Schools

Lab results show unusually high levels of lead were found at several schools in San Diego County during the school year, according to documents obtained Friday by NBC 7. Results for San Diego County from the State Water Resources Control Board show one sample recorded lead at three times the levels acceptable by the state. As schools test for lead in their drinking water, they are required by the state to fix problems if they discover lead in water at levels greater than 15 parts per billion (ppb).

 

BLOG: How Reservoirs Can Adapt To Flooding In a Warmer Climate

Much has been written on the potential effects and adaptations for California’s water supply from climate warming, particularly from changes in snowpack accumulation and melting, sea-level rise and possible overall drying or wetting trends. But what about floods? In a paper in the journal San Francisco Estuary and Watershed Science, we along with coauthors from the United States Army Corps of Engineers review much of the literature to date and examine how the Shasta, Oroville and New Bullards Bar reservoirs might adapt to floods in a warmer climate, including a climate that is either wetter or drier.

How Tough Will It Be To Rebuild Oroville Dam’s Spillway? State Hopes Model Will Help

Anyone who contemplated the wreckage of the Oroville Dam’s main spillway back in February — either while water was pounding down the shattered concrete structure or when the flow was stopped later and the enormity of the damage was fully visible— probably had this thought cross their mind: “That is going to be tough to fix.” Officials with the California Department of Water Resources were apparently thinking something similar.

How Climate Change Could Threaten The Water Supply For Millions Of Californians

When it comes to California and climate change, the predictions are staggering: coastal airports besieged by floodwaters, entire beaches disappearing as sea levels rise. Another disturbing scenario is brewing inland, in the sleepy backwaters of the Sacramento-San Joaquin Delta. It’s a threat to the Delta’s ecosystem that could swallow up a significant portion of California’s water supply. Scientists from government and academia say rising sea levels caused by climate change will bring more salt water into the Delta, the hub of California’s water-delivery network.

California Reservoirs Holding Nearly Twice As Much Water As At The Drought’s Height

California’s reservoirs are brimming after a winter of relentless storms and a late-spring heatwave that thawed the a big chunk of the snowpack. The Golden State’s system of 154 major reservoirs is holding 32,464,000 acre-feet according to the most recent June 12 state report with data pulled from an array of entities that own and manage these bodies of water, including the Department of Water Resources, the Bureau of Reclamation, the Army Corps of Engineers and several city water departments.

 

Environmentalists, Fishing Groups File Lawsuits To Block Delta Tunnels Plan

Kicking off what are expected to be years of legal battles, a coalition of environmental and fishing groups on Thursday filed the first major lawsuits over California Gov. Jerry Brown’s $17 billion plan to build two massive, 35-mile-long tunnels under the Delta to make it easier to move water from Northern California to the south. The Natural Resources Defense Council, Defenders of Wildlife, Bay Institute and Golden Gate Salmon Association filed two lawsuits in U.S District Court in San Francisco.
