Partnerships between the U.S. Geological Survey (USGS) and the Minnesota Department of Health (MDH) enhance the State's ability to evaluate human-health risks from chemicals of concern (CECs). MDH considers CECs for toxicological review and development of drinking-water guidance. The human-health information generated by the MDH puts the chemical data into an environmental health context.
A new U.S. Geological Survey (USGS) report summarizes the major findings of national and regional assessments of groundwater quality in 40 Principal Aquifers in the United States. Knowledge of contaminant occurrence and the factors that control contaminant concentrations can ensure the availability and quality of this vital natural resource in the future.
The U.S. Geological Survey (USGS) and the U.S. Environmental Protection Agency (EPA) are collaborating on a field-based study of chemical mixture composition and environmental effects in stream waters affected by a wide range of human activities and contaminant sources.
U.S. Geological Survey (USGS) scientists determined that endocrine disrupting chemicals (EDCs) were present in wastewater treatment plant (WWTP) effluent, water, and fish tissue in urban waterways in the Great Lakes and upper Mississippi River Regions (Indiana, Illinois, Michigan, Minnesota, and Ohio) during 1999 through 2009.
Based on a multi-agency, multi-year study of one of the most complex river systems in Pennsylvania, the two most likely causes for the population decline of smallmouth bass in the Susquehanna River are endocrine-disrupting compounds and herbicides; and pathogens and parasites.
Pharmaceuticals, hormones, personal care products, and other contaminants of concern associated with everyday household activities were found in adjacent shallow groundwater near two septic system networks in New York (NY) and New England (NE). Factors influencing movement to shallow groundwater and the types of chemicals found include population served by a septic system, site conditions such as soil permeability, and the properties of the chemicals.
Neonicotinoid insecticides (neonicotinoids) were present in a little more than half of the streams sampled across the United States and Puerto Rico, according to a new U.S. Geological Survey (USGS) study. This is the first national-scale study of the presence of neonicotinoids in urban and agricultural land use settings across the Nation and was completed as part of ongoing USGS investigations of pesticide levels in streams.
In order to properly maintain your well and septic system, you should know the location of all components on your property. You should have a map showing the location of the well, septic tank, distribution box or pump tank, and leach field/absorption area or sand mound along with other underground utility lines.
In places around the world, supplies of groundwater are rapidly vanishing. As aquifers decline and wells begin to go dry, people are being forced to confront a growing crisis.
The question of whether it is environmentally correct to buy a real Christmas tree has been asked repeatedly in recent years, and an expert in Penn State's College of Agricultural Sciences wants to lay it to rest permanently.
Soil acidification from acid rain that is harmful to plant and aquatic life has now begun to reverse in forests of the northeastern United States and eastern Canada, according to an American-Canadian collaboration of five institutions led by the U.S. Geological Survey.
Urban environments struggle with contaminated water running off, causing pollution and algal blooms. In response, cities often use natural landscapes of soil, grasses, and trees. These biofiltration systems capture and filter the runoff. Researchers measured how well tree species grew when watered with stormwater, and how well they took extra nutrients out of the stormwater.
Results of a 15-year study of factors affecting populations of Eastern brook trout with climate change show high summer air temperatures have a large influence, in particular on the smallest fry and eggs, which are most important to wild trout abundance in streams. Findings are expected to help nonprofit watershed conservation groups and state and federal wildlife managers identify, prioritize and protect habitat at sites most likely to have fish in the future.
Looking for a new way to engage community members in streamside restoration efforts? The Penn State Agriculture and Environment Center (AEC) and Penn State Extension have worked to develop a citizen science monitoring protocol that can easily and quickly show volunteers the good that comes from installing best management practices.
A new article has identified escape from aquaculture facilities, releases in the wild due to pet/aquarium trade and stocking activities as the main pathways of alien species introduction in European lakes and rivers. Germany, the UK and Italy are the main entry gateways. The authors recommend tightened controls, and improved prevention and management measures in order to halt the increasing trend of freshwater alien species introductions in Europe.
The Penn State Master Well Owner Network (MWON) recently added 17 new volunteers who completed the Fall 2015 online training courses. These volunteers join nearly 700 others who are dedicated to providing unbiased, research-based education on the proper management of private water wells, springs and cisterns.
The over-tapping of the High Plains Aquifer's groundwater beyond the aquifer's recharge rate peaked in 2006, new research shows. Its use is projected to decrease by roughly 50 percent in the next 100 years.
Do you teach about water? Could you teach about water? – Dive Deeper is the Summit for You!
Penn State Extension Educator, Jim Clark, received the 2015 Outreach and Education Award from the North American Lake Management Society (NALMS) Award Program Chair, Dick Osgood, at their annual conference in Saratoga Springs, NY, on Thursday, November 19.
The Penn State Extension Water Resources team recently reported their annual program impacts related to drinking water education.
