More sample points needed. Control costs by manual samples using handheld gps meters for exact locations. Gas Chromatography testing for pesticides and herbicides. Atomic Absorption Spectroscopy for heavy metals. Do not miss chance to get river rate of flow at time of sample m3/s. Take many notes on river. Try to keep change of custody if possible. Take lab tech. sample tests at time of collection. Labs that do GC and AA may not be close. Ice in containers. Take photos of river. Next sample point may change. Handheld gps meter and photo is best at same time. You may be by yourself so get it your best.
