Healy — "An observation-well network has been established throughout Florida to evaluate the status of ground water resources in each aquifer." As shown in the key, the red numbers represent continuous ground water stage recorders, the blue represents annual water level measurement, the orange shows semiannual, the black is bimonthly or other frequency and the green numbers are sample and chemical analyses which may include wells in the preceding categories.
