RGISC’s environmental outreach and public advocacy revolves around sound science.
Its staff and board members make decisions, and take public positions affecting environmental issues, based on scientific research and data. For nearly 20 years, RGISC scientists have conducted monthly water quality testing at multiple sites along the Rio Grande.
Data from these sites – between four and eight sites – are submitted to federal and state authorities and is part of the Texas Clean Rivers Program database. Water quality parameters include Total Dissolved Solids, Total Suspended Solids, turbidity, pH, oxygen, temperature, as well as E. coli and fecal coliforms
RGISC was also actively involved in the Laredo Bacteria Study, which took place in May and August 2011, with a final report released in November 2012. The study involved collecting and testing 118 water samples from nearly 49 sites along a 27-mile stretch of river between Laredo and Nuevo Laredo.
Furthermore, RGISC scientists co-authored a study documenting antimony contamination at the mouth of Manadas Creek, where it drains into the Rio Grande, from the former Anzon smelter plant.
