Lab staff activities + capabilities

Established in 1972, OWML has been providing service for monitoring water quality of rivers, streams, reservoirs and other waterbodies and environmental samples. OWML is equipped for a variety of matrix analyses, such as drinking water, non-potable water, sediment, and fish samples. Testing areas include:

– Dissolved earth ions and metals

– Inorganic chemical and nutrient laboratory testing (nitrogen and phosphorus)

– Organic carbon (total and dissolved)

– Microbiological testing (total coliform, fecal coliform, E. coli and Enterococci)

– Synthetic organic compounds (SOCs)

– Solids (total dissolved solids, total suspended solids, turbidity)

– Pesticide, and Contaminants of emerging concern (CECs)

OWML ensures that analytical methods applied are in compliance with The NELAC Institute (TNI/National Environmental Laboratory Accreditation Conference), EPA, ASTM, and Standards Methods for Water and Wastewater.

In 2010, OWML was certified by the Virginia environmental laboratory accreditation program (VELAP), under Virginia regulation 1VAC30-46 and TNI 2009 Standard, as a commercial-grade laboratory.
