The City of Sunnyside has released its 2010 water quality report, which customers will find in their utility billing for June.
The report, released annually, is to assure residents they are receiving safe and reliable drinking water, according to Sunnyside officials.
The report explains where city drinking water comes from and what substances can be expected to be found in the water, as well as how the water is treated.
A table will be included with the report, comparing Sunnyside's drinking water to standards set by the Environmental Protection Agency (EPA) and the Washington State Department of Health.
Residents, according to officials, will see in the report that drinking water in Sunnyside meets all federal and state requirements.
Some small contaminants will be indicated in the report, however the presence of those contaminants does not pose a health risk, according to Sunnyside officials.
Residents concerned with the information can call the EPA's safe drinking water hotline to find out more information about the contaminants at 1-800-426-4791.
The report provides levels of iron, manganese, sodium, fluoride, sulfate, nitrates and several other minerals and elements found in each well in parts per million.
With nitrate levels being a concern of Lower Valley residents, the EPA standard is no more than 10 parts per million in drinking water. The highest level of nitrates were found in well 11. That level was 1.6 parts per million, well below the standard.
Sodium levels were the closest to standards set by the EPA. Well seven and well eight were found to have 18 parts per million, and well nine was found to contain 19 parts per million. The EPA standard is 20 parts per million. It is believed the sodium levels are high due to natural geology of the location of the wells.
Bacterias like Giardia, E. Coli and Coliform were not found in the Sunnyside drinking water. Also absent was Asbestos and Cryptosporidium.
