There are a vast number and types of water bodies throughout Florida, each with its own unique set of properties and characteristics. We can provide everything needed to create a successful water quality monitoring program. Our vast array of instruments includes multi-parameter meters, submersible data sondes, continuous recording water level dataloggers, tipping bucket rain gauges, rainfall collection systems, portable refrigerated sampling systems, Doppler flow meters, and data telemetry systems. From collecting samples for analysis to evaluating the results, our team has the knowledge, experience, technology, and expertise to meet our clients’ needs. Our established relationships with several state certified laboratories provide our clients efficiency without sacrificing quality.
Florida groundwater provides us with vital drinking and irrigation water. Water quality monitoring provides assurances that the integrity of this supply is maintained. Our experienced team specializes in designing and implementing groundwater quality monitoring programs based on a strong knowledge of water quality regulations, and a client’s particular project needs. We enjoy strong working relationships with local regulatory agencies and can expertly and efficiently carry out their monitoring requirements. From measuring conductivity to collecting samples for laboratory analysis, our team can handle the monitoring needs throughout the life of a project, allowing our clients to successfully address regulators’ concerns and manage their project’s groundwater resources in a sustainable manner.
In a state with over 2,200 miles of shoreline, Florida’s coastal waters require special attention to protect these fragile ecosystems. The estuaries along our coasts are comprised of many different habitats including mangroves, tidal flats, sea grass beds and oyster reefs. Each of these different habitats is a vital part of the overall health and stability of our coastal waters. Our team of environmental and coastal scientists understands the complexities of these marine environments. Our monitoring experience within Outstanding Florida Waters and national estuaries strengthens our ability to meet the regulatory needs of our clients efficiently and effectively.
Our clients’ water quality monitoring needs sometimes extend beyond the actual water bodies themselves. State-issued Environmental Resource Permits (ERP) often require sediment samples to be collected from lake bottoms, in addition to traditional water quality samples, to assess deposition. Our team of scientists has assisted clients with a variety of projects including channel dredging and marina expansions. Our strong working relationships with regulators and familiarity with FDEP sediment assessment regulations allow us to efficiently carry out successful monitoring programs. We maintain a variety of vessels and sampling equipment in-house, which allow us to quickly and thoroughly meet the needs of each project.
Many of Southwest Florida’s water bodies have been listed as “impaired” by FDEP, meaning they fail to meet one or more state water quality standards. As a result, the FDEP will establish Total Maximum Daily Loads (TMDL) for those water bodies. We help our clients approach the TMDL process in a proactive manner. By developing scientifically sound water quality monitoring programs, we can evaluate the impacts of a project on the watershed basin. We then make recommendations as to how these impacts can be reduced through a variety of Best Management Practices (BMP) tailored to suit our clients’ needs.
The Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection (FDEP) offer cost sharing programs to assist clients with funding for certain types of water quality projects. Two such programs are the Section 319 Nonpoint Source Grant and the State Water-quality Assistance Grant (SWAG). The rules governing those programs vary and require a great deal of understanding to be used effectively. Our team is familiar with the eligibility requirement for each of these funding mechanisms and can help our clients match their needs to the funding program that is best suited for their project. We can then help them to prepare a proper application that includes the parts needed to be considered for funding.
Federally funded projects often require the development of a comprehensive Quality Assurance Project Plan (QAPP). We have vast experience preparing and implementing these plans for clients throughout Florida. As a requirement of the Grant Work Plan, the QAPP is instrumental in explaining how monitoring and water quality sampling will be used to determine the project’s success. The sampling locations, parameters to be tested, frequency, and duration of sampling are critical components that are outlined as part of this document.
Numerous rivers, streams, and lakes throughout Florida have been labeled “impaired” based on water quality criteria for bacteria indicator organisms. However, bacteria come from many sources, which may or may not pose a serious health hazard to humans. Tracking the source of the bacteria is crucial to addressing the problem. By sampling for specific substances used by humans, along with extracting DNA from the samples to be tested and compared to the DNA from animals, birds, humans, and other known markers, we can help our clients determine the source of impairment so that they can take appropriate action.
Determining the source of pollutants in water is relatively simple if you can point to the end of a pipe where the polluted water is coming from. Unfortunately, most of the water quality issues we face today are much more complex and require sophisticated methods of testing and analysis to help evaluate the sources of pollution. Our experienced water quality scientists work in conjunction with laboratories equipped to analyze samples for a vast array of chemicals, including isotopic forms of nitrogen that can help determine sources of nutrient pollution. Proper sampling and analysis is critical to providing this non-point source evaluation.
