Test kit directions can be retyped and laminated so that these can be taken out to do the field testing. Data recording - one team Graphing the data requires this team to express the information so that changes occurring over time can be documented. These graphs provide an analytical look at the various chemical factors and their changes seasonally and from human impact.

After the sample is screened, portions of the sample can be analyzed using a stereoscope or a magnifier to find macroinvertebrates. Samples should be kept moist during this examination period so as to not stress any macroinvertebrates. Insect larvae and various types of mollusks are popular in our samples. Grab samples may be refrigerated for further study. It is important that samples are moist while being refrigerated.
