Hydrologic Associates
personnel have decades of experience collecting and analyzing surface water data throughout Florida. This experience includes design and construction of surface water gages, stream gaging (discharge measurements) in streams and at water level measurements, development of rating curves, statistical analysis of hydraulic data, storm water modeling, basin (watershed) modeling and tidal flushing analysis.

Hydrologic Associates has in-house capabilities to complete the tasks listed above and has the following types of equipment and instrumentation:

  • Water level recorders: Analog, digital, and electronic.
  • Current meters (discharge): Price Current Meters, Pygmy Meters, Marsh-Mc Birney, Flow meter.
  • Boats, cranes, bridge boards, A-Reels and Wading Rods for discharge measurements.
  • Staff gage installation.

Surface Water Installation in South Miami-Dade County

Hydrologic Associates
personnel have decades of experience in the collection and analysis of groundwater data throughout Florida, Mexico, and the Caribbean. Our experience includes conducting long and short term aquifer tests (the latter mainly consisting of step-drawdown and specific capacity tests) on single or multiple wells. Using the proper analytical solution (such as confined or unconfined aquifer, leaky aquifer, fractured rock aquifer, etc.) derivation values of aquifer transmissivity, hydraulic conductivity, leakage, specific capacity, and storage coefficient can be calculated.

Hydrologic Associates has in-house capabilities to complete the tasks listed above and has the following types of equipment and instrumentation for quantitative analysis of groundwater.

  • Pressure Transducers: In Situ Trolls, In Situ Multi Channel Hermit
  • Centrifugal Pumps: With intake 2-inch, 3-inch, 6-inch discharge hoses
  • Downhole Pumps: Grunfos 5, 10, and 20 horsepower for various flow rates and head
  • Line Shaft Pumps - (3) 8, 12 and 16 inch
    • With diesel PTO rated at 1000 to 10,000 gallons per minute
  • Borehole Camera Black and white
  • Flow Meters
    • Haliburton in-line (2)
    • Marsh- Mc Birney
    • Cross Correlation (capable of measuring large pipes to 60 inches and volume)


Hydrologic Associates have over 30 years experience in the collection and analysis of water quality data. Sampling media includes surface waters (streams, lakes, and canals), groundwater, soil, subsurface geologic material, bottom sediments and tidal areas. HAI operates under a quality assurance/quality control (QA/QC) plan approval by the Florida Department of Environmental Protection (FDEP). HAI utilizes selected state and federally certified analytical laboratories for sample processing and analysis. HAI personnel collect water quality data from various media on nearly a daily basis. HAI has the following equipment and expertise to accomplish the tasks listed above.
