When developing vacant land, you must know the pertinent features to ensure the project can continue successfully. Evaluating groundwater for possible contaminants is especially important, as many sites in Alaska use private wells to source water for drinking and other purposes. Scheduling groundwater sampling is crucial in this regard, but you should also understand what type of contaminants are most likely to be present. 

3 Common Groundwater Contaminants and Their Effects

1. Nitrites

Many types of fertilizers use nitrogen compounds like nitrites to facilitate the healthy growth of plants and grass. While beneficial to nature, nitrites can cause quite a lot of harm to humans if they make their way into the groundwater and end up being consumed. They're particularly harmful to pregnant women and babies, as they're linked to numerous birth defects. Because these effects are so serious, groundwater sampling is crucial to locate nitrites and utilize the correct filtering technology to mitigate the threat. 

2. Microbes 

While naturally occurring, microbes like bacteria and viruses can cause major illness when consumed. For instance, the presence of E.coli bacteria in water can cause significant intestinal distress, such as vomiting and diarrhea. Microbes can be introduced to groundwater due to improperly maintained septic systems or sewer lines. They can also result from runoff from nearby farms and manufacturing plants. Fortunately, microbes can be removed with disinfectant solutions, such as UV light or chlorine treatment. 

3. Volatile Organic Compounds (VOCs)

VOCs are derived from paint, insecticides, cleaning products, medications, plastics, degreasers, and many other products. They're associated with a range of serious diseases and ailments, including cancer and organ damage. They can make their way into the environment via regular household use as chemicals are washed down drains. However, they can also be introduced via industrial plants. Certain types of filtering systems, such as those using activated carbon, can eliminate VOCs from the water supply.
