The primary duties of this position will involve conducting site assessment, file reviews, technical reviews, and field work involving subsurface investigations and remediation.
Are all New Jeresy EPs recommending NJDEP file reviews of HRECs with NFA's? If the contamination on the subject property is below the old standard but above a current standard the HREC rises to the level of a REC. Does this invalidate the NFA? Is a new case number generated with the NJDEP?
Researchers have begun to explore the insecticide group known as neonicotinoids and the effects that they are having on U.S. waterways. Neonicotinoids are similar to nicotine in chemical makeup and includes about half a dozen types of insecticide. While research regarding the effect on waterways is a relatively new environmental trend, the chemicals have been widely used since the 1980s in over 120 nations worldwide.
Most recently, the insecticides have been scrutinized after they began to wipe out entire bee populations across Europe. The European Union eventually ended up banning the use of the neonicotinoids all together in order to protect any remaining bee colonies. Many environmentalists in the U.S. would like the Environmental Protection Agency (EPA) to do the same in order to protect its native bee and insect populations.
Neonicotinoids have become widely used in the Midwestern United States to protect large industrial corn and soybean crops from insects. The chemicals are not sprayed over crops like a traditional insecticide. Instead, the neonicotinoid coats each seed before the crop is planted. Once the seeds are watered they begin to leach the chemical into the groundwater. Neonicotinoids are extremely water soluble and have been found in many Midwestern waterways, including the mighty Mississippi River. The U.S. Geological Survey took approximately 79 water samples from nine waterways in the region. Of those sampled, three quarters of the streams experienced water contamination, testing positively for high levels of neonicotinoids. The insecticide also does not break down easily, so it remains in waterways over a significant period of time.
Critics of the study argue that insecticide levels found in waterways are well below EPA standards and should not be considered an alarming concern. The researchers conducting the study acknowledge that the levels are below EPA environmental regulations, but they feel that neoniconoids can be harmful to insects at far lower levels. Environmentalist stress that an insect may not killed by a chemical but may become completely useless and defenseless. For instance, neonicotinoids attack the nervous system of an insect and may make them unable to eat, fly, crawl, or reproduce. Weak insects are easily consumed by predators and future generations are not replenished without adequate mating.
Neonicotinoids have not been linked to any significant dangers to the health of human beings, but could have a serious effect on smaller animal populations. Proponents of neonicotinoids are quick to point out that they are far less lethal to mammals than traditional insecticides. Despite those claims, bird populations in the Midwest have been on the decline and researchers believe there is a correlation to insect deaths. Birds have far fewer insects to consume due to the pesticide’s devastation of insect populations. The birds are also eating the seeds that were completely coated in the pesticide as well as snacking on exposed bugs. Similarly, fish living in the sampled waterways may have fewer insects to feed on. Researchers feel that there simply is not enough information on how insecticides affect waterways and the associated wildlife and hope continued studies like the one conducted by the U.S. Geological Survey can help toward a healthier environmental future.
Water contamination due to pharmaceuticals has become a major current environmental issue in recent years. The contamination is a result of the increased number of drugs that human beings consume and flushed down the toilet as waste. The drugs enter the water table since they are often not removed in the standard water treatment process. One group of researchers in Sweden decided to study the effects that anti anxiety medication exposure would have on the Eurasian Perch.
The Swedish group tried to look at the experiment with a fresh perspective, not assuming that the exposure to contaminated water would be detrimental to the perch. They accomplished this by changing the variables in the study. First, instead of using lab bred fish in perfect health that would have near perfect survival rates they decided to use both two year old wild fish that had no exposure to pharmaceuticals as well as unexposed eggs.
Researchers then exposed half of the young fish and half of the eggs to oxazepam, a popular anti anxiety medication. Many of the young fish and eggs did not survive from both the control and non control groups. This was expected as mortality rates are high in the wild. The perch exposed to the anti anxiety pharmaceutical surprisingly ended up having a higher rate of survival than the control group.
The explanation for such unexpected findings is due to behavioral changes in the exposed fish. The fish exposed to oxazepam were much more aggressive, more active, and spent much more time alone. It is believed that the anti anxiety medication cause the perch to be much less stressed and therefore much more brave. They then felt unafraid to venture out alone and spend more time finding food. The well fed fish were stronger and more likely to survive. If the fish were in the wild as opposed to the laboratory setting, this bravery could prove dangerous. Lone fish would become a much easier meal for predators.
Despite the seemingly positive results of exposing fish to water contaminated with pharmaceuticals, scientist remind us that an increased perch population could be devastating to the ecosystem of a waterway. The entire food chain could be thrown off. Increased fish populations would require more food, so their prey would dwindle.
Overall, studies like these have revealed jut how little is known about how the introduction of pharmaceuticals into our waterways and how they will affect the environment. The study also shows that there are no simple results; fish are not simply dying in mass quantities making the water contamination obvious, instead evolutionary behaviors are being changed. These changes as small as they may appear can have devastating effects on a delicate ecosystem.
The United State Environmental Protection Agency (EPA) has responded to the Swedish study and the changes that were made to the control group in the research process. While the EPA believes the findings are interesting they do not feel making significant changes to the way in which research is conducted would be appropriate based on one study.
I've uncovered evidence, potentially, of explosives manufacturing at a site from around the turn of the 20th century (ca. 1905). Has anyone ever run into munitions manufacture, use, or disposal dating that far back in the course of property development? Any insight into how such sites have developed and what the primary contaminants were from around this time?
I'm looking to incorporate some technology to streamline the flow of information from EPs in the field and co-workers updating reports in the office. The cStat app looks like it has the potential to facilitate the flow of data, however I just wanted to see what other programs / apps EPs on this forum have had success with and like?
Thanks for your input!
Loving County, Texas has an official population of ninety-five people, but spans about 650 square miles of the Texas Dessert. This highly rural area is seeking a very large payment from the federal government of $28 billion to store radioactive waste resulting from spent nuclear reactors across the nation. The federal government is in a bit of a rush to come up with an alternative storage location after plans to build an extensive storage site at Yucca Mountain in Nevada were abruptly cancelled.
Residents of the rural Texas County feel as though the potential federal money could be put to great use in building roads, shipping in more water, and establishing an official municipal government. Love County would like to grow. Not all ninety-five residents are on the same page, a few feel that despite the potential benefits, inviting nuclear waste into the community is never a good idea. Other residents are more tongue in cheek, stating that the area is perfect since if something catastrophic should occur the county’s population is so small no one will notice.
Love County faces some serious competition in getting the money for a storage site, since two New Mexico communities about fifty mills away from the Texas border, are also in the run. Love County is advocating itself as the best candidate since they have plenty of space to store the hazardous waste material in cement casks, as well as the potential area for those casks to eventually be buried for permanent storage. This would save time, money, and prevent hazards since the radioactive waste would not have to be transferred again.
The Texas Counting has been busy working with the State’s governor as well as other legislators to help convince the federal government that they are the best choice. If the sites in New Mexico are chosen, Texas would not receive any of the benefits but would still be put at risk due to the proximity of the potential sites.
Last week’s ban of water consumption in Toledo, Ohio should come as no surprise since the pollution in Lake Erie has been a current environmental issue for many years. The underlying issue is that huge algae blooms are occurring due to an increased amount of phosphorus in the water. The phosphorous is a direct result from the fertilizer used in farming and is washed into local waterways.
A thick algae has taken over Lake Erie, consuming almost all of the water’s oxygen creating dead zones. Almost nothing can survive in these areas. The algae is also toxic, creating microcystin which causes diarrhea, vomiting, and liver issues in humans. The toxin has proven fate to pets and wild animals that have drank directly from an affected waterway as well.
Toledo and Lake Erie are not alone in this algae bloom. Waterways in several states like Minnesota, Nebraska, California, and Massachusetts have also seen the thick sludge. The Gulf of Mexico experienced an algae bloom the size of New Jersey last year.
It does not appear that much is being done to prevent these blooms, due in large part to the power of the agricultural industry. The federal Environmental Protection Agency (EPA) has had issues implementing the Clean Water Act since the phosphorous is not directly linked to a single source, but rather multiple sources. The U.S. Supreme Court has historically handed down decisions curtailing the breadth of the Clean Water Act as well. Many people feel as though the Act steps on personal freedoms. Without environmental regulations, the EPA must rely on voluntary compliance to standards.
Despite difficulties there have been some efforts made to restore the health of Lake Erie and the other Great Lakes. Congress has given $1.6 billion to the Great Lakes Restoration Initiative. This Initiative helps show farmers more efficient and safer fertilizer techniques. It also helps create additional wetlands, which serve as a natural filter for phosphorous runoff before it reaches larger bodies of water. The state of Ohio has also created several task forces and committees with similar goals of reducing phosphorous runoff.
