What’s in Your Water Pt. 2
Last week we talked about three of the most common contaminants in the Lincoln, NE water system. For a quick refresher, visit last week’s blog. This week, we’re diving into the six other contaminants found in the EPA’s latest assessment which took place from January to March of 2017.
Note: Information from this article and last week’s article comes from the Environmental Working Group (EWG). The EWG’s website states: “We are a non-profit, non-partisan organization dedicated to protecting human health and the environment.” Their work created a free online database which publishes information from public water tests. All recommended contaminant levels come from the California Office of Environmental Health Hazard Assessment or the EPA. For Lincoln, NE, all tap water contaminants were in accordance with federally mandated levels during its latest assessment.
There are a couple ways Chromium (hexavalent) enters drinking water. Typically, contamination is due to pollution from industrial factories or mineral deposits in systems which utilize groundwater. This carcinogen has been linked to cancer; fortunately, Lincoln’s water system tested at 14 times lower than the national average.
Small amounts of this contaminant are found in certain types of oceanic algae, but it is most often found in chlorinated water. Chlorine is a fairly standard treatment for drinking water, so this cancer-linked contaminant is found very commonly. The Lincoln, NE level of dibromochloromethane exceeds the national average by 5.83 ppc. At a recorded 8.79 ppb, the level of dibromochloromethane is eight times higher than the recommended level.
Dichloroacetic acid can cause pregnancy issues and increase cancer risks in some. It is one of five kinds of haloacetic acids regulated by the federal government. The levels of dichloroacetic acid in Lincoln, NE were 2.18 ppb higher than the national average and 4.14 ppb higher than the state average.
The facility tested positive for Radium-228. The EWG site did not specify the level to which Radium-228 was detected, but did mention that radiological contaminants have been linked to cancer risks and poor fetal development. It also mentioned that radiological contaminants are typically the result of minerals or mining operations.
Total trihalomethanes (TTHMs)
Another contaminant linked to cancer, the amount of total trihalomethanes refers to a group of 4 chemicals. The amount of total trihalomethanes was bad but not horrible, coming in at 45.6 ppb less than the legally mandated levels. Unfortunately, the Lincoln, NE level was also 26.84 ppb above the national average.
Like dichloroacetic acid, trichloroacetic acid is a type of haloacetic acid linked to cancer risks. Lincoln tested below the national average of 4.92 ppb by only .44 ppb.
