PFAS regulations are rapidly evolving as governments expand reporting requirements, develop new testing strategies, and establish stricter standards for protecting public health and the environment. With increasing attention on PFAS contamination in drinking water and other environmental media, businesses across multiple industries must stay informed as federal and state regulatory frameworks continue to develop.
Ethylene oxide (EtO) is a widely used industrial chemical whose high reactivity makes it valuable in manufacturing but also poses significant health risks, including respiratory effects, neurological impacts, and cancer from long-term exposure. As industries seek to monitor EtO at increasingly lower concentrations, advanced technologies such as infrared absorption analyzers and cavity ring-down spectroscopy are providing faster, more sensitive detection capabilities than traditional monitoring methods.
The City of Steamboat Springs partnered with Spheros Environmental to address complex Yampa River temperature issues threatening cold-water aquatic life through regulatory support, monitoring, modeling, and restoration strategies. LRE supported the City in securing a temporary temperature modification and developing innovative water quality trading approaches that could improve river health, reduce compliance costs, and provide broader environmental benefits.
As part of a Clean Water Act 316(b) study, in-river ichthyoplankton samples were collected by the client to characterize baseline fish community populations in the river throughout the year. Entrainment samples were collected by filtering water in the plant behind the intake screen.
The NARS surveys are designed to assess the status and changes in the quality of the nation’s coastal waters, lakes and reservoirs, rivers and streams and wetlands.
James Adamson and fellow researchers Thomas LaVanchy, PhD and Michael Kerwin, PhD recently published an article to draw attention to the confluence of water security factors in Cape Town.
The Metro and South Platte Basin Roundtables strongly advocate for the development of additional surface and groundwater storage, further research of aquifer storage and recovery (ASR), and investigation into additional off-channel storage and reservoir sites in the basin.
We have heard a lot about global warming and its impact on tropical rainforests - however, this phenomenon can have dramatic effects on temperate rainforests as well. A recent study published in BioScience examined the repercussions of glacier melt in temperate rainforest ecosystems, and how climate change will drive the future of nearshore aquatic ecology.
Measuring the health and conditions of an ecosystem is a complex, involved and daunting task that can be tackled in one of many ways. Bioassessment services have long been utilized for just this purpose, and increased understanding of the structure and function of ecosystems has driven advancement and acumen in the field. That may be why so many ecological research and assessment organizations are turning to bioassessment as a means for determining the integrity of ecosystems and establishing what steps need to be made for preservation purposes.
Nutrient pollution in the Mississippi River basin and surrounding waters has been an issue of great importance for water quality consultants, regulatory bodies and other invested parties. One organization that holds a stake in the efforts to curtail such pollution is the Hypoxia Task Force, which recently announced that it has created new strategies to speed up the reduction of nutrients in the waterways of the Mississippi-Atchafalaya River Basin.
