Our scientists and engineers offer a host of surface water evaluation services to help gauge the health of creeks, streams and rivers. Hydro-Terra Group scientists have broad experience in measuring total stream flow, bedload sampling, suspended sediment sampling, channel mapping, long-term monitoring of temperature & stream stage as well as many other physical factors that affect stream health.
For compliance monitoring for maintenance of nominal Streamflow, HTG can site, design, permit, and construct stream gauging stations with flow capacities ranging form a few gallons per minute to over 100 cubic feet per second.
In addition to the physical stream characteristics, our staff tests, monitors, and samples for various important chemical quality parameters. Our field data collection includes dissolved oxygen, salinity, pH, iron, hardness, free chlorine, dissolved solids, and temperature as well as developing specific testing procedures for other chemicals suspected of being introduced into streams. In this, HTG provides grab and automated sampling services.
HTG staff have designed, permitted, and constructed numerous water pumping and treatment systems. These have included commercial systems for shopping centers and manufacturing plants, municipal pump houses and treatment facilities, manufacturing plants, and assumption systems for supply and management of irrigation water. Parameters we have successfully treated include pH, hardness, nitrates, iron and manganese, volatile organic compounds, and radon.
