  • Any resident with new information to report, including any dead animals in or near the lake, should contact Thurston County Public Health at 360-867-2626. 

  • The Summit Lake Community Association is forming a Water Quality Team to develop water quality related projects and solutions going forward. To stay informed about this team's work, or to get involved, please email the Association at summitlakeslca@gmail.com and ask to be put on the Water Quality Team email list.         

Private Lab Testing Available to Residents

  • There are different methodologies for testing non-potable water and drinking water. Ask to be sure the lab is accredited for the test you are looking for. For drinking water samples the method is EPA 545. This method used for clean tap samples but is not appropriate for thick blooms. Discuss your particular situation with the lab. Typically the laboratory will supply the correct sample bottle and directions which are likely to include keeping the sample cold and dark during shipping, ship overnight to the lab, and letting the lab know if there is chlorine in the sample.
