At last nights City council meeting Mr. Corbin addressed the council about needing data for a sewage system. Well here you go.
Mr. Corbin had it half right. But when you compare drinking water to ground water there are 2 sets of standards.

RE: Joint Use Sewer Treatment Plant.
A Closer Look At A Perceived Problem
Winzler & Kelly looked at the issue of nitrate contamination in the groundwater. Based upon monitoring performed by the Twentynine Palms Water District, the concentrations of nitrates appears to be stabilized at levels that are safely below the maximum contamination level (MCL) established by the State’s drinking water standards. Therefore, the need for citywide wastewater treatment facilities does not appear to be imminent. However, the Regional Water Quality Control Board, which is the State agency responsible for regulatory authority of wastewater discharges, has consistently expressed concerns and has required three recent subdivisions to install package treatment systems.
