Statewide Guidance by County
Since 2005, the Well Educated program has provided a means of state-wide ground water quality data collection. This data is processed and ultimately stored in a large-scale database. Certain aspects of the data can be extracted from this database to create data products such as water quality results maps and summary statistics. Currently, program data collected over the years 2015-2017 has been processed and compiled for use in these products.
