Lake Chabot Machine Gun Range
With the start of World War II, the Navy established a gunnery range on a watershed area adjacent to the Lake Chabot Reservoir.
The Navy built a circuit training range on which gunners would fire turret mounted machine guns that were built onto the beds of light trucks, rail cars, and fixed firing platforms. Gunners would engage targets that were on an automated circuit on small rail cars. This would simulate firing in air-to-air combat.
In addition to the automated circuit range, there was a shotgun range that was used for the primary training of aerial gunners. This was basically a skeet range in which trainees would learn the fundamental techniques of aerial gunnery, such as proper sighting of fast moving targets.
The base ceased operations in 1947.

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the California State Water Resources Control Board, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the U.S. EPA (January 2019 - March 2019), tap water provided by this water utility was in compliance with federal health-based drinking water standards.
Legal does not necessarily equal safe. Getting a passing grade from the federal government does not mean the water meets the latest health guidelines.
Legal limits for contaminants in tap water have not been updated in almost 20 years.
The best way to ensure clean tap water is to keep pollution out of source water in the first place.
