Drinking water bacteria analysis
In 1974, Congress passed The Safe Drinking water Act which requires EPA to regulate contaminants which may be health risks and may be present in drinking water. Septic systems are the largest of all contributors of wastewater to the ground and among the most frequently reported sources of contamination. Wastewater from septic systems may include many types of contaminants such as nitrates, harmful bacteria and viruses. Chemical substances commonly used by homeowners such a pesticides, paints varnishes and thinners can also end up in the groundwater. Chemical contamination is especially dangerous since it may be permanent. Some chemicals are almost impossible to remove from the groundwater. Bacteria and viruses generally are removed in the unsaturated zone. But in fractured rock where groundwater flow rates can be high, these bacteria and viruses may be transported very rapidly and could contaminate nearby drinking water. It is critical that your well casing is sealed and separated the required distance from the septic system’s absorption field. This will keep the contaminated water from seeping into the drinking water. Some of the diseases caused by unsafe drinking water are Hepatitis A, Gastroenteritis, Encephalitis, Typhoid, Shigellosis, Cryptosporidiosis, and Giardiasis.
