Containers must be clean and free of any residue from former contents. One-gallon plastic drinking water jugs make good containers for water chemistry testing. After the container is empty, rinse it two to three times with the water that will be tested. Containers with residues of milk, juice, bleach, etc. may alter test results. Plastic containers are preferred, and should have a secure, tight fitting lid.
Samples for chemistry testing are accepted
Monday-Friday from 8 a.m. to 2 p.m.
Approximately 8-ounces is needed per test. A one-gallon container is adequate to do all 22 chemistry tests available.
Water samples must have the name of the owner, or the submitter on the container. Multiple samples from different locations should be clearly marked.
All samples should be kept cool until they are brought to the lab. Samples may be refrigerated or kept at a normal room temperature of less than 80 ° F until they are brought to the lab. It is not necessary to put them on ice. Samples should not be frozen.
All samples should be received in the lab within 24 hours of the sample collection time. Some tests, such as hydrogen sulfide, chlorine, and pH, have critical time constraints.
