M&A’s support of the 2017 Arroyo continues a longstanding tradition of sponsoring a summer internship for a University of Arizona student who is interested in gaining experience writing about environmental and water resource issues. The Arroyo is the annual newsletter of the UA’s Water Resources Research Center (WRRC). This year’s edition, published June 1, looks at Arizona’s history of […]

M&A’s work featured in Leapfrog case study
The New Zealand-based company Leapfrog recently featured M&A’s work in the Salta Province of Argentina, where we have been investigating lithium brine resources since 2012. M&A has been working in collaboration with our client Eramine Sudamerica S.A. to develop drainable and extractable resource estimates for brine aquifers in the Ratones and Centenario salars based on […]
Upcoming California conferences
The Groundwater Resources Association of California (GRAC) is holding a special conference on May 3–4 to address the needs of the state’s new Sustainable Groundwater Management Act (SGMA), which requires the development of a Groundwater Sustainability Plan (GSP). Tim Leo, one of our principal hydrogeologists and lead for California projects, will be giving a talk […]

M&A hosts AHS intern
Each year, the Tucson chapter of the Arizona Hydrological Society (AHS) awards an intern scholarship — named after Leonard Halpenny, who initiated the award — to a deserving UA student. This scholarship provides an opportunity for students to gain some practical experience and exposure to many facets of the water resources industry. Participating employers typically […]
Challenging a paradigm: What we learned by comparing three common groundwater sampling methods
As a result of this analysis, M&A obtained regulatory approval to use low-flow sampling methods for long-term monitoring, reducing sampling costs by 75 percent. M&A recently had the opportunity to challenge a long-established practice that hydrologists have applied when collecting groundwater samples. This practice, which has been largely driven by environmental regulators, involves “purging” three […]
