GROUND WATER PROTECTION
The PHMDC staff collects groundwater samples for lab analysis at five closed sanitary landfills in the City of Madison. Groundwater monitoring wells are sampled semi-annually using state-of-the-art dedicated bladder pumps and low-flow sampling techniques. The PHMDC laboratory analyzes the samples for metals, nutrients, and inorganic indicator parameters. Organic analyses are coordinated with an outside laboratory. This work is performed to ensure that the contaminants potentially present in the landfill do not migrate to the lakes and groundwater.
