Drinking Water Analysis
Colorado Analytical Laboratory maintains certification by the Colorado Department of Public Health and Environment (CDPHE) to analyze drinking water for inorganic contaminates (metals including copper & lead), cyanide, fluoride, nitrate & nitrite, and coliform bacteria.  All test methods have been approved by CDPHE.  Our state certification requires us to successfully analyze blind performance evaluation samples and submit to routine on-site inspections.  A strict quality control plan must be maintained and adhered to in order to retain certification.  Sample results can be forwarded to CDPHE upon request.

Colorado Analytical offers a number of test packages designed to evaluate the overall quality of well water.  The Domestic Water Quality test package is normally requested by homeowners for this purpose.  Standard Nutrient/Irrigation water test packages are also offered for greenhouses and agronomic uses.  The Complete Nutrient package provides the primary nutrients contained in the standard analysis along with additional trace elements.
