Incentivizing Groundwater Recharge: A Berkeley Law Symposium

September 10, Berkeley

Groundwater aquifers continue to be depleted as pumping exceeds recharge in many regions of the world, adversely affecting human and environmental systems. Managed Aquifer Recharge (MAR) is one crucial strategy to bringing these groundwater resources into sustainable balance. However, understanding is sorely lacking about how to effectively incentivize MAR, and how to navigate the institutions relevant to MAR.

This symposium will seek to fill these knowledge gaps, addressing key questions including: Who benefits from groundwater recharge? What conditions are necessary for a recharge project to succeed? How can implementation be incentivized? How should recharge projects be governed? What emerging and novel techniques hold promise for future MAR?

The symposium aims to move the conversation on MAR forward. To this end, presenters will highlight successful and novel recharge projects from across the U.S.. Experts will also speak to scientific, legal, and management issues in recharge, and how they influence potential incentive schemes. These insights will help inform practitioners and scholars about recharge and chart a path towards developing a broadly applicable framework for enabling recharge.

GRA SACRAMENTO BRANCH MEETING: Factors Affecting 1,2,3-Trichloropropane in Groundwater in California

September 11, 5:30pm

1,2,3-TCP is a volatile organic chemical of eminent concern due to its carcinogenic, mutagenic, and reproductive effects, and its frequent occurrence at concentrations of concern worldwide. California recently established a maximum contaminant level (MCL) for 1,2,3-TCP of 0.005 μg/L.

Statewide, 1,2,3-TCP was detected at concentrations above the MCL in 6.5% of 1,237 wells sampled by the U. S. Geological Survey (USGS).   … Most of the detections occurred in the San Joaquin Valley, where 1,2,3-TCP was detected above the MCL in 16% of USGS sampled wells and 18% of DDW wells. In the San Joaquin Valley, 1,2,3-TCP occurrence and concentrations are related to legacy nonpoint source fumigant inputs and hydrogeologic factors.

The highest concentrations of nonpoint-source 1,2,3-TCP are in young, shallow, oxic groundwater beneath primarily orchard/vineyard crops. These areas are in coarse-grained sediments that promote rapid recharge. 1,2,3-TCP frequently co-occurs with 1,2-dibromo-3-chloropropane (DBCP), 1,2-dichloropropane (1,2-DCP), simazine, and high nitrate concentrations. Analysis of groundwater age dates and temporal changes in 1,2,3-TCP indicate that 1,2,3-TCP is persistent throughout modern age groundwater, showing little evidence of degradation.
