Ground Water: Field Water Quality Measurements Mobile App

The Ground Water: Field Water Quality Measurements mobile app provides you with easy-to-use, recommended procedures for consistently collecting quality, representative groundwater samples and measurements. Before going out in the field, you should develop a sampling plan and a QA/QC plan. All sampling personnel should use the related ground water apps. This app offers an easy to use Field Water Quality Measurements Checklist. Remember you device needs to validate your credentials against the server at least every 7 days.
