Emerging Contaminants

LimnoTech is at the forefront of confronting the nation’s most vexing water quality challenges, including new threats to our aquatic ecosystems and water resources. Emerging contaminants, including pharmaceuticals and personal care products, pose a suspected or known risk to human health and the environment. Emerging contaminant issues often garner sensational headlines but the problems are complex, the scientific understanding is often incomplete, and a one-size-fits-all solution is inadequate. With our multi-disciplinary staff of proven innovators, we have the expertise to understand emerging contaminant problems and the creativity and resourcefulness to develop effective and workable solutions for our clients.

Compounds of emerging concern, such as pesticides, pharmaceuticals, and personal care products threaten the health of aquatic biological communities and may also pose a risk to humans. Cyanotoxins, such as Microcystins, are produced by cyanobacteria (also called blue-green algae) and can threaten our drinking water supplies and limit our opportunities for recreation. Poly- and perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and their breakdown products pose a threat to public health. Excess slime, foam and trash creates objectionable aesthetic conditions that may result in economic consequences. These are just a few examples of the emerging contaminant topic areas that fall under the umbrella of “emerging contaminants” that LimnoTech has worked on for our clients.

LimnoTech has the capability to deliver effective and feasible solutions to the wide-ranging and complex problems caused by emerging contaminants. Our work, and the solutions we develop for our clients, is based on the most current scientific research, is tailored for each site’s specific risk, and is innovative, cost-effective, and able to withstand rigorous scientific and regulatory review. We offer a deep toolbox based on current science to identify and distill each problem and situation down to the critical core issue(s) and then develop sensible solutions. Our tools include advanced statistics, models, spatial analysis, monitoring and real-time sensors. With over 40 years of experience and renowned industry expertise, LimnoTech provides solutions to meet your needs.
