This is historical.&#8217;\u201d<\/p>\n<p>While the irrigation gates were closed, Lombard and a team took between 100 and 120 samples of ditch sediment to establish a baseline for heavy metal contamination.<\/p>\n<p>\u201cWe took soil samples from ditches that had not had contaminated water in them,\u201d he said. \u201cWe want to get baseline data, to have when we re-evaluate the sediment at the end of the irrigation season. We want to see if any heavy metals were transferred to the ditches when they were running after the spill.\u201d<\/p>\n<p>Consumers\u2019 concern regarding farmers irrigating with the river water after the spill were expressed during a public forum in Farmington on Sept. 1. The biggest concern was whether the water is distributing heavy metals from sediment onto the surface soil and into the plants.<!--more--><\/p>\n<p>\u201cThere is still an unknown of whether the water will spread heavy metal contaminants that could have settled in the river and irrigation ditch bottoms,\u201d Lombard said.<\/p>\n<p>\u201cFarmers have had to decide whether to use the water or not,\u201d Lombard said about the river water, which the New Mexico Environment Department and U.S. Environmental Protection Agency tests indicate is safe to use. \u201cIf they choose to not irrigate, they will lose thousands of dollars or even their sustenance. We are lucky \u2013 we have a well, so we continued our drip irrigation as usual when the irrigation ditches were shut off.\u201d<\/p>\n<p>He added that the farmers market manager in Durango, where he sells his produce, inquired about the protocol used during and after the spill.<\/p>\n<p>During the forum, farmers asked representatives of the New Mexico Environment Department, U.S. EPA and New Mexico Department of Agriculture, along with NMSU agriculture specialists, about the danger and potential impact on their crops and animals.<\/p>\n<p>\u201cThe critical period is over,\u201d said Tim Hanosh, veterinarian and director of New Mexico\u2019s Diagnostic Laboratory. \u201cThe levels may have been high but not extremely high or high enough to cause acute problems.\u201d<\/p>\n<p>He advised livestock growers to keep an eye on their herd for any signs of unexplained illness, which could indicate an accumulation of heavy metals in their system, but from the EPA and NMED reports, he did not expect to see any such signs.<\/p>\n<p>To help alleviate that concern, Richard Strait, state soil scientist with the Natural Resources Conservation Service, contacted David Weindorf, Texas Tech University associate dean of research in the College of Agricultural Sciences and Natural Resources, to help out.<\/p>\n<p>\u201cThey got in touch with me because I use a portable x-ray fluorescence spectrometer extensively,\u201d Weindorf said. \u201cPoint it at the soil, take a reading &#8212; and 60 seconds later, you have information about the soil.\u201d<\/p>\n<p>Weindorf and Lombard worked together for three days taking readings of soil in fields along the Animas and San Juan rivers, as well as the river banks.<\/p>\n<p>\u201cThis equipment is amazing,\u201d Lombard said. \u201cUsing the traditional way of testing soil, it takes weeks to get the results back. Plus it costs between $50 and $100 for each sample tested.\u201d<\/p>\n<p>On the first day, 40 screenings were conducted in six hours. Weindorf said the levels of pollution were well below the level for concern.<\/p>\n<p>\u201cWe were looking for levels of lead, cadmium, arsenic, copper and a lot of other different things,\u201d Weindorf said. \u201cLead is one of the metals used as a tracer for most pollution analysis. The average for our first 40 samples was 20 to 30 parts per million. To give you a context, the U.S. residential danger level for lead in soil is 400 parts per million. This soil is well below that level.\u201d<\/p>\n<p>NMSU College of Agricultural, Consumer and Environmental Sciences is committed to future studies of the Animas and San Juan rivers riparian area to see what effects the Gold King Mine spill may still have.<\/p>\n<p>\u201cNow we have baseline data for future studies,\u201d Lombard said. \u201cIt will be important for us to continue to sample the soil to ensure that heavy metal contamination levels do not increase.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Will the Gold King Mine spill spread heavy metal contaminants that will settle in the river and irrigation ditches?
