Naturally occurring metals in unregulated domestic wells in Nevada, USA
<p>The dominant source of drinking water in rural Nevada, United States, is privately-owned domestic wells. Because the water from these wells is unregulated with respect to government guidelines, it is the owner's responsibility to test their groundwater for heavy metals and other contaminants. Arsenic, lead, cadmium, and uranium have been previously measured at concentrations above Environmental Protection Agency (EPA) guidelines in Nevada groundwater. This is a public health concern because elevated levels of these metals are known to have negative health effects.</p> <p>We recruited individuals through a population health study, the Healthy Nevada Project, to submit drinking water samples from domestic wells for testing. Water samples were returned from 174 households with private wells. We found 22% had arsenic concentrations exceeding the EPA maximum contaminant level (MCL) of 10 mg/L. Additionally, federal, state, or health-based guidelines were exceeded for 8% of the households for uranium and iron, 6% for lithium and manganese, 4% for molybdenum, and 1% for lead. The maximum observed concentrations of arsenic, uranium, and lead were ~80, ~5, and ~1.5 times the EPA guideline values, respectively. 41% of households had a treatment system and submitted both pre- and post-treatment water samples from their well. The household treatments were shown to reduce metal concentrations, but concentrations above guideline values were still observed. Many treatment systems cannot reduce the concentration below guideline values because of water chemistry, treatment failure, or improper treatment techniques. These results show the pressing need for continued education and outreach on regular testing of domestic well waters, proper treatment types, and health effects of metal contamination. These findings are potentially applicable to other arid areas where groundwater contamination of naturally occurring heavy metals occurs.</p>

InSAR stack of the 2008 Wells, Nevada earthquake from Envisat descending track 399 processed with Gamma
<p>A stack of unwrapped interferograms on Wells, Nevada for the <a href="https://earthquake.usgs.gov/earthquakes/eventpage/nn00234425/executive">2008 Wells earthquake</a>.</p> <p>Sensor: Envisat ASAR descending track 399 frame 2871</p> <p>Time: 2007.07.09 - 2008.09.01, 11 acquisitions, 51 interferograms</p> <p>Processor: GAMMA</p> <p>A minimum coherence of 0.3 is chosen during phase unwrapping, thus the low coherent pixels are assigned the zero phase value (green in the unwrapPhase_wrap.png).</p> <p>Tropospheric delay estimated from ERA-5 using PyAPS is attached.</p> <p>This is an input dataset for the time series analysis with <a href="https://github.com/insarlab/MintPy">MintPy</a>.</p>
