Arsenic contamination of ground water is found in many countries throughout the world, including the US. [2] The World Health Organization recommends limiting arsenic concentrations in water to 10 μg/L, although this is often an unattainable goal for many problem areas due to the difficult nature of removing arsenic from water sources. [3]
For example, median levels in Nevada were about 8 μg/L [15] but levels of naturally occurring arsenic as high as 1000 μg/L have been measured in the United States in drinking water. [16] Groundwater associated with volcanics in California contain As at concentrations ranging up to 48,000 μg/L, with As-bearing sulfide minerals as the main ...
Other states that have issued PFAS standards include Michigan, New York and Vermont. [79] Between 2016 and 2021 the U.S. Geological Survey (USGS) tested tap water from 716 locations across the United States, finding PFAS levels exceeding the EPA advisories in approximately 75% of samples from urban areas and in approximately 25% of rural areas ...
NMED said 20,000 water users in Sunland Park and Santa Teresa are served by the Camino Real Regional Utility Authority, a water district that tested positive for arsenic in 2023.
On March 15, the state pulled 10 drinking water samples. ... one of 10 drinking water samples had levels above the federal drinking water maximum contaminant level for arsenic. The sample that ...
KEYPORT — A slag-like material on the beach in Keyport contains high levels of arsenic and should be avoided, state environmental officials warned.
This is a list of Superfund sites in Washington State designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to ...
Increased levels of skin cancer have been associated with arsenic exposure in Wisconsin, even at levels below the 10 ppb drinking water standard. [147] According to a recent film funded by the US Superfund , millions of private wells have unknown arsenic levels, and in some areas of the US, more than 20% of the wells may contain levels that ...
