Why is desalination bad?
What are the environmental impacts of desalination? … Desalination has the potential to increase fossil fuel dependence, increase greenhouse gas emissions, and exacerbate climate change if renewable energy sources are not used for freshwater production. Desalination surface water intakes are a huge threat to marine life.

Will California build desalination plants?
Conclusion. Many Californian coastal communities are planning to make seawater desalination a permanent part of their water portfolio within the next five to ten years. More than 20 seawater desalination plants supplying up to ten percent of California’s total water demand are projected to be built by 2020.
Is fire hydrant water safe to drink?
Hydrant flushing is necessary to test the hydrants to make sure adequate flow and pressure is available. Flushing is also done to remove sediment from the pipes in order to maintain water clarity and quality in the distribution pipes. Your water is safe to drink.
