Meeting/Event Information

Technical Talks: The Minnesota Section of AIPG holds technical talks September through May, generally the first Tuesday of the month. The talks are designed to fulfill 1 Professional Development Hour (PDH). Professional Geologists, as licensed in the State of Minnesota, are required to complete 24 PDHs every biennium licensing period, including 2 PDHs of ethics.  The technical talks feature important subjects of interest to professional geologists.

The cost includes a buffet lunch and is $21 for non-members, $16 for members, and $0 for students when registering in advance.  We have limited same-day registration for $25. 

*During the pandemic, we are webcasting our Technical Talks.  The cost is $10 for non-members and $5 for members. You must register by 11 AM the day of the talk to be sent the login link/information. Students may attend free of charge. Fees go toward supporting the online meeting platform and the Education Fund. Your contribution to the Education Fund helps support many activities, please see our Giving Back page.

As always, non-members and non-geologists are welcome to attend!

Micropollutants in Groundwater Downgradient from Wastewater Land Application Sites

by Sarah Elliott, US Geological Survey


Presentation Abstract

Methods of wastewater land application, such as on-site treatment systems, are currently used in Minnesota. Wastewater discharges can contain micropollutants such as pharmaceuticals, personal care products, and other organic wastewater chemicals, which can affect soil and shallow groundwater. We evaluated the presence of micropollutants in shallow groundwater near wastewater land application sites. Two types of sites were targeted: (1) large subsurface treatment systems (LSTS) and (2) rapid infiltration basins (RIB). Thirty-four micropollutants were detected, 18 of which were pharmaceuticals. Maximum concentrations ranged from 1.1 (glyburide) to 960 (sulfamethoxazole) nanograms per liter. Results indicate that these land application methods can contribute to micropollutant loading of surface waters and domestic wells via groundwater discharge.
