Chemistry Services


Water Management Laboratories, Inc., is State of Washington Department of Health certified to perform inorganic chemical analyses on drinking water. The following tests are for drinking water only. Water Management Laboratories, Inc., is also State of Washington Department of Ecology accredited for environmental and wastewater samples. Environmental, Wastewater, Raw water, Soil, Food, and Shellfish analyses are also available. The price on these may vary due to the condition and type of sample. Standard Methods for the Examination of Water and Wastewater or EPA methods are used for all analyses. [ ServicesForm pdf, FC28-PC 18.pdf ]
