Coastkeeper says well sub-surface intakes are better option than 50 years of coastal and marine life damage
ORANGE COUNTY – January 15, 2016 — Orange County Coastkeeper says a new Independent Science Panel study to analyze the use of subsurface wells for the proposed Poseidon Huntington Beach desalination plant shows that wells can produce the water needed to run the plant.
Poseidon has contended for fifteen years that wells could not produce enough water to supply the source water needed to operate the plant. The report released yesterday (username: “public”, password: “ocean03”) by the Independent Coastal Commission Panel shows that wells can supply the amount of water needed to run the desalination plant. Coastkeeper says the Orange County Water District should consider wells over irreversible damage to coastal waters and accept the small impact wells would have on the aquifer as part of the cost of the plant.
“If Orange County must build this desalination plant that it doesn’t need, then wells shouldn’t be disregarded as acceptable options for building responsibly,” says Garry Brown, President and founder of Orange County Coastkeeper. “The way this plant is currently planned is not responsible and puts Orange County’s coastal communities, marine life and economy at risk.”
Desalination plant intakes draw in seawater to send through a process that removes the impurities and salt from the water. Currently, there are two categories of widely used desalination plant intakes: open intakes and subsurface intakes (wells and infiltration galleries).
Surface intakes catch and kill countless amounts of marine life, fish and larvae on a daily basis. The environmental impacts of using a surface ocean intake are significant and well documented. The State Water Board has required power plants to quit using these methods and, according to the new statewide desalination policy, the State Board does not want desalination plants using them either.
By installing subsurface intakes, marine-life mortality is eliminated.
The most recent report showing that using wells can supply the water needed to run the plant adds to the last report from the Independent Coastal Commission Panel, which stated that infiltration galleries for the Huntington Beach desalination plant were too expensive. Coastkeeper said this was another reason why the location is a bad idea and alternative site studies need to be conducted.
The issues related to the plant’s proposed intake options join the following reasons why the Huntington Beach desalination plant is not worth the risk:
- The plant is still proposed to be built on an earthquake fault in a tsunami run up zone
- The brine discharge from the plant will still degrade water quality and marine life
- There is no proven need for the water
- Poseidon has not adequately considered alternative sites for the plant
- Poseidon has not adequately considered the impacts of the plant on Marine Protected Areas
- Poseidon has not adequately addressed the greenhouse gas footprint
“As it stands the proposed Poseidon—Huntington Beach facility will damage the three E’s of Orange County: environment, economy and energy,” said Brown.
