In the 1930s, there was so much sewage off the coast that it was corroding the hulls of Navy ships and driving away tourists. For years, the city intentionally dumped untreated sewage into San Diego Bay, hoping the tides would take it away. San Diego has long struggled to deal with its sewage problems. That imported water is less and less dependable, thanks to climate change, overuse or stricter environmental regulations.īut the recycling project is perhaps possible only because of compromises made after years of legal wrangling over sewage which, unlike drinkable water, the city has often had too much of. Right now, San Diego is largely dependent on a tiny bit of rain that falls locally, a plant in Carlsbad that makes some ocean water drinkable and a lot of water imported from hundreds of miles away. The project is sold as a major leap for the region’s water supply. Last week, state lawmakers approved a bill meant to end the dispute and get the recycling project, now known as Pure Water, back on track. The latest was a dispute among contractors, labor unions and the city. There have been innumerable hurdles along the way – in the court of public opinion, and in actual court. Now, after years of scientific progress, regulatory wrangling, political ups and downs, and searching for the money, the city is getting ready to put shovels in the ground and get to work on a multi-part, multibillion-dollar project that will eventually provide a third of the city’s drinking water.

The first stab at recycling wastewater involved a series of ponds in Mission Valley that grew hyacinths, long-rooted plants that gobble up sewage and leave relatively clean water behind. San Diego water officials have looked at turning sewage into drinking water for nearly 40 years. Inside of the North City Pure Water Facility / Photo by Megan Wood
#Pure water free#
Ultrapure water dispensed by ELGA’s water purification systems has been shown to be free from trace contaminants to meet the demands of instruments used for trace element analysis.A Brief History of Pure Water’s Pure Drama | Voice of San Diego Close As such, the reliability of trace element analysis must be protected using ultrapure water that is virtually free from impurities. This includes causing errors in blanks and calibration samples, or artificially high sample concentrations. This requires highly sensitive and accurate analytical techniques, with detection resolutions being as low as parts per trillion!īut the downside of this highly sensitive detection is that the data outputs can be adversely affected by even tiny amounts of contamination by additional elements or ions. Trace element analysis involves detecting very low (trace) concentrations of certain chemical elements in a sample. How does Ultrapure Water Help Trace Analysis?
