Water officials seek input on chloride removal

A meeting is scheduled tonight for public comment on methods for removing chloride from the Santa Clara River.

Under consideration will be a total of six options regarding possible methods for treating wastewater discharged into the river.

Although levels of chloride in the water have dropped - thanks in part to the removal of more than 7,300 water softeners in the Santa Clarita Valley - detected amounts of the naturally occurring salt are still over the limit of 100 milligrams per liter of water, according to information from the Sanitation District.

District officials said there are three course of action: construct a chloride-removal plant to meet the 100-milligram limit; build a facility in Ventura County to offset a higher 117-milligram limit; or face steep fines from the Regional Water Control Board for noncompliance.

Levels of chloride higher than 100 milligrams per liter are thought to be harmful to crops downstream that draw their water from the river.

There are total of six options to avoid noncompliance, according to district officials: using ultraviolet light to remove micro-organisms instead of using more traditional methods that add chloride; building an advanced wastewater-treatment facility that uses micro-filtration and reverse osmosis to remove chloride; building a pipeline that would transport water treated by reverse osmosis to blend with other treated water before being discharged to the Santa Clara River; building a deep well injection system; building a pipeline to flush the chloride-tainted water out to sea; or using a large amount of recycled water, which could drop the amount of treated wastewater runoff to the Santa Clara River.

In making their comments, residents are asked to consider air quality and climate change, biological resources, cultural resources, energy, transportation and traffic, greenhouse gas emissions, land use, noise and hydrology and water quality.

Tonight's meeting will be held at the city of Santa Clarita Activities Center at 20880 Centre Pointe Parkway, with a question-and-answer session beginning at 6:30 p.m. and the meeting beginning at 7 p.m.
