Abstract: Contamination of groundwater with naturally occurringarsenic is widespread throughout much of South and SoutheastAsia and poses a serious health risk to the millions of individualswho consume this water. However, it is unclear why dissolvedarsenic concentrations have reached the high levels currentlyobserved in aquifers throughout the region. In particular, theinfluence of surface water recharge on arsenic contaminationremains unresolved. To address this issue we studied thehydrogeology and geochemistry of an arsenic contaminated site inVietnam (continued on next page).
Hydrogeologic Factors Influencing High Levels of Groundwater Arsenic in
South and Southeast Asia
Cont’d: This field site is located adjacent to the Red River,which presently recharges the aquifer as a result of intensivegroundwater pumping. We find that the effect of riverinerecharge on groundwater arsenic concentrations is controlled bythe geomorphic setting of the river-aquifer interface. Aquifersinland of freshly deposited river sediments are highlycontaminated with dissolved arsenic, whereas aquifers inland ofnon-depositional river segments host low arsenic groundwater.We also observe that the generation of high arsenic requires amuch larger input of organic matter (which fuels arsenicmobilization) in areas of the aquifer not recharged by river wateras compared to areas recharged by the river. These findingssuggest that aquifers throughout the region may be susceptibleto further contamination as a result of hydrologic changesinduced by extensive groundwater pumping for water supply.

President’s MessageDear Hudson Mohawk Geologists,
We had a great meeting last month where Dr. Dax Soule presented his upcoming field excursion to the Bransfield Strait between the South Shetland Island and the Antarctic Peninsula. His excitement for this work is very contagious and we hope that he can come back and present his findings in a year or so.
This month we have Dr. Mason Stahl from the Union College geology department presenting his hydrogeologic study concerning high levels of arsenic in groundwater in south and southeast Asia. With his background as a consultant in environmental engineering in the northeast U.S. this should be an interesting talk that many of us can relate to.
Let’s not forget that Jesse Vollick is working on filling some other speaking slots for upcoming meetings. If you have some research, or a particular project you would like to present to your colleagues, please let us know and we will look for a meeting date for a presentation. Your help in this aspect is greatly appreciated as we do our best to bring intriguing and relatable projects to each meeting.…. Continues on Next Page.

Keep an eye out for volunteer opportunities aswe enter the holiday season and begin to thinkabout the Gem & Mineral Show at the NYSMuseum and then the Howes Cave trips forexample in the second half of our HMPGAseason.
I hope to see you all on the 14th (2ndWednesday due to Thanksgiving).

Mineral of the MonthRhodochrosite
Primary used for a minor value gemstone. Can be found in a range of pink to red crystals and has a perfect cleavage on 3 planes. Crystals forms are not commonly found. It is found world wide but has
nearby notable locations in Massachusett: Betts Manganese Mines, Forge Hill Iron Mine. New Hampshire: The famous Palermo No1 Mine, Parker Mountain Mine, and Stony Mountian.
Calcite Group • Formation: Trigonal crystals. • Localities: Worldwide• Chemical Composition: MnCo3• Hardness: 3.5 - 4
This mineral often occurs in moderate to low temperature hydrothermal veins, and with late stages of hydrothermal minerals in pegmatites.

In 2017, 8.2 Tehuantepec, Mexico quake ruptures both the mantle and the crust! October 25, 2018- Sciencedaily.com
November 2018 8
“Initially, it was believed the earthquake was related to a seismic gap, occurring where the Cocosocean plate is being overridden by a continental plate, in an area that had not had a quake ofsuch magnitude since 1787. Subduction zone megaquakes generally occur near the top of whereplates converge.
The epicenter, however, was 46 kilometers (28 miles) deep in the Cocos plate, well under theoverriding plate and where existing earthquake modeling had said it shouldn't happen, a 13-member research team reported Oct. 1 in the journal Nature Geoscience after an analysis ofdata from multiple sources.
"We don't yet have an explanation on how this was possible," said the study's lead author DiegoMelgar, an earth scientist at the University of Oregon. "We can only say that it contradicts themodels that we have so far and indicates that we have to do more work to understand it."
