A hydrogeologic study must be performed first. Key factors in the study will include wastewater flow rate, depth to groundwater, direction of groundwater flow, type of soil, distance to sensitive receptors such as drinking water supplies, wetlands, and surface water bodies, and the proposed level of wastewater treatment.
Groundwater moves very slowly and can take years to naturally cleanse itself even if the source of the pollution is removed. It is possible to employ sophisticated treatment processes to remove contaminants, but that can be very expensive. Rather than clean contaminated groundwater, it is better to prevent the pollution from happening in the first […]
Rivers and streams are called surface water bodies. Groundwater provides much of the flow for surface water bodies, contributing approximately 492 BILLION gallons per day to U.S. surface waters and habitat. If the groundwater is polluted, it can impact the use of these surface water bodies for drinking water. High levels of nutrients, such as […]
There are many potential sources of contamination to groundwater. Improperly treated wastewater from malfunctioning treatment facilities and on-site systems is one major source. Other sources include: Leaking underground storage tanks Landfills Hazardous waste sites Excessive use of road salts and fertilizers
Approximately one-half the population of the United States uses groundwater as a drinking water supply. Most groundwater is naturally clean and free of pollutants, but contamination of groundwater can cause serious health effects from harmful bacteria and nitrates. Elevated nitrate levels can pose a risk to infants. Babies under six months of age are particularly […]
