Water monitoring: Standard operating procedures

Standard operating procedures (SOPs) reflect how agency staff and contracted partners complete agency-funded field activities. The SOPs provide step-by-step instruction on water quality monitoring for everything from determining water chemistry in lakes or streams to biological monitoring procedures. The agency has also developed steps to avoid the transfer of aquatic invasive species.
