Long Island Sound Water Quality Improving In Response To Significant Reductions In Nitrogen Pollution

Long Island Sound Water Quality Improving In Response To Significant Reductions In Nitrogen Pollution As summer approaches, EPA officials are highlighting water quality improvements in Long Island Sound resulting from almost 50 million pounds of nitrogen pollution kept out of the Sound each year. A peer-reviewed study from the University of Connecticut published earlier this year showed that improved water quality can be attributed to successful programs in Connecticut and New York to upgrade wastewater treatment plants to remove nitrogen before treated sewage is discharged into the Sound. These two state-led programs have reduced millions of pounds of nitrogen pollution from being discharged into Long Island Sound, which has led to increased oxygen concentrations in the Sound in the summer months and, as a result, improved ecological conditions for fish and other organisms.

Lead levels in urban soil are declining but hotspots persist

E-Mail DURHAM, N.C. - Decades after federal bans ended widespread use of lead in paint and gasoline, some urban soils still contain levels of the highly toxic metal that exceed federal safety guidelines for children, a Duke University study finds. To conduct their study, the researchers analyzed and mapped soil lead concentrations along 25 miles of streets in Durham, N.C., a city of about 270,000 people. They found that while soil lead levels have generally decreased since the 1970s, they have decreased much less near residential foundations than along streets. The researchers collected soil samples near foundations of houses built before 1978. Samples within a meter of the older homes averaged 649 milligrams (mg) of lead per kilogram (kg) of soil, more than three times the average level detected near streets, which was 150 mg/kg.

Decades after ban, lead in soil still puts kids at risk

Decades after federal bans ended widespread use of lead in paint and gasoline, some urban soils still contain levels that exceed federal safety guidelines for children, a new study finds. Researchers analyzed and mapped soil lead concentrations along 25 miles of streets in Durham, North Carolina, a city of about 270,000 people. They found that while soil lead levels have generally decreased since the 1970s, they have decreased much less near residential foundations than along streets. The researchers collected soil samples near foundations of houses built before 1978. Samples within a meter of the older homes averaged 649 milligrams (mg) of lead per kilogram (kg) of soil, more than three times the average level detected near streets, which was 150 mg/kg.
