LOS ANGELES (CBSLA) — The water quality in Los Angeles is not great, but a new study shows it is improving.

UCLA gave Los Angeles County an overall C+ grade in its annual water report that was released Wednesday.

The report included a C+ grade for water supply and consumption even though 60 percent of the water in L.A. County comes from outside of the region.

The quality of drinking water, however, has risen to a B+ grade.

According to the report, the L.A. water infrastructure was at a C+ while surface water received a D grade due to pollution.

Many of these grades are expected to improve in the future with $300 million recently set aside for better water capture efforts that would L.A. to source more water locally.
