The Mohawk Valley Water Authority has a certified laboratory to perform several chemical and microbiological analyses. The lab holds accreditation certificates from both New York and Pennsylvania. Every member of our technical staff has a Bachelor’s Degree, minimally, so you are assured a well-qualified team is analyzing samples on your behalf. The typical laboratory hours are Monday-Friday from 8:30am - 4:30pm. Because of specific method holding times, some analyses can only be performed on certain days. Please refer to the instruction sheets below for detailed information on sample collection, holding times, and analysis. Feel free to contact our office if you have any questions about sampling or results.
