Water Quality SondesHydrolab Series 5 with Hach LDO Helps Louisiana Department of Environmental Quality Assess Post-Katrina Situation
In the aftermath of hurricane Katrina, when the levies broke around New Orleans, the Louisiana Department of Environmental Quality (LADEQ) was pressed into service. The agency relied on its inventory of water quality monitoring instruments to track where water was, and what areas were contaminated. The department owns as many as 80 separate Hydrolab water quality monitoring instruments between all of its divisions, and they have typically been able to use Hydrolab instruments for 8 to 10 years. The instruments in the department's inventory include Minisonde 4a and Series 5 instruments with Hach LDO. Read More.
Hydrolab DS5OTT and Hydrolab Provide Integrated, Turnkey Solution for the River Tyne
In August 2003 Posford Haskoning, a leading Engineering Consultancy in the UK, contracted OTT Hydrometry Ltd (OHL) to design, deploy, and manage a system of four water quality monitoring buoys on the lower tidal reach of the River Tyne in northeast England. The system is based on an integrated solution that combines the strength of products from Hydrolab and OTT to provide a complete turnkey solution for the site.

Pressure Sensor and LoggerOTT Orpheus Mini and ITC Provide Remote Access to Water Level Data Critical to Monitoring Levee Repairs
In late August of 2005, the storm surge from Hurricane Katrina damaged two sections of the back levee near Braithwaite and Scarsdale, two towns located Southeast of New Orleans, Louisiana. The substantial damage to the Caernarvon outfall area and the Breton Sound estuary prompted the Interagency Advisory Committee and the Caernarvon Technical work group to discuss changes to the operational plan that would benefit the affected area. The changes need to allow for discharges up to 7,500 cubic feet per second for 20 days during a portion of the year. Read More.
Integrated SystemsLake Oswego, Oregon – Storm Water Runoff
For the City of Lake Oswego, Oregon, quantifying the effects of watershed urbanization upon Oswego Lake – an important local fresh water reservoir – is instrumental for proving the future success of up-stream pollution prevention programs. Hach Environmental supplied the instrumentation that allowed Lake Oswego to create two compact and unobtrusive water quality monitoring stations that leave a small footprint and have low impact to the surrounding natural environment. In addition, the Hach Environmental instruments deliver data in a repeatable, low-cost way that was necessary for the long-term success of the monitoring program.
