All of the water supplied by the District is produced by five deep groundwater wells. The water produced by the District’s wells is of superior taste and quality. Unlike many of the regional surface water systems, there are no chemicals added to the District’s water for disinfection purposes. Since disinfection is not required, the District’s water is generally less expensive than disinfected surface water. The cost savings from this is passed on directly to our customers.
In 2006 a new arsenic level standard went into effect for public water systems. The allowable maximum contaminant level for arsenic was reduced from 50 parts per billion (ppb) to 10 ppb. Arsenic is a naturally occurring element in the earth’s crust. As a result of the new standard, the District studied the arsenic levels in the District wells. It was determined that water from its Wells 3 and 4 occasionally exceeded the maximum contaminant level. Therefore, the District decided to be proactive and build an arsenic removal facility.
The District recently constructed a new 0.5 MG reservoir, booster pump station and arsenic removal facility just north of the Crest development. The reservoir is buried and the arsenic removal and booster pump station are located on top of the reservoir. Water from Wells 3 and 4 is now routed directly to the arsenic removal facility prior to entering the distribution system. As water is filtered through the media, arsenic particles passively adsorb or adhere onto the iron surface without the use of chemical additives.
The District’s water continues to be tested to the Department of Health requirements and with completion of the arsenic facilities, meets all water quality standards.
