Go to the EPA Ground Water and Drinking Water webpage. Under “Consumer Confidence Reports,” click on the “Find your local CCR” link on the right. Select California as your state. Enter the name of your water system or the city, town, or county you live in, such as San Diego. Click on the “Search” button. Once the information loads, scroll down to locate your water system or district that serves your area by clicking on the blue link in the "CCR Website" column. Alternatively, search Google with phrases like “CCR Water San Diego, California.” If you cannot find a report or if you use a private well, identify the nearest city with at least 10,000 residents. Review the water quality data and any violations mentioned in the report. Write a short essay of at least one page discussing issues related to groundwater in California and specifically in the San Diego area. Include your city and state in the paper.

Groundwater plays a vital role in California's water supply, especially in urban areas like San Diego. As a semi-arid state, California heavily relies on groundwater sources, which provide about 35% of the state's water needs under normal conditions and up to 40% during drought periods (California Department of Water Resources, 2021). However, the increasing demand for water, climate change, and pollution pose significant challenges to groundwater sustainability and quality.
In San Diego, groundwater is a critical component of the local water supply system, supplementing imported water from the Colorado River and Northern California. According to the San Diego County Water Authority’s Consumer Confidence Report (CCR) for 2022, the groundwater in the region largely meets regulatory standards, but there are concerns about certain contaminants such as nitrate, arsenic, and volatile organic compounds (VOCs). These issues are linked to urban runoff, agricultural activities, and natural mineral deposits, which can leach into aquifers and degrade water quality (San Diego County Water Authority, 2022).
One major issue facing groundwater in California, including San Diego, is over-extraction. Excessive pumping of aquifers depletes water reserves, leading to land subsidence, which damages infrastructure and reduces the natural recharge capacity of aquifers. The California State Water Resources Control Board reports that over half of California’s aquifers are either under severe stress or overdrafted, making sustainable management imperative (State Water Resources Control Board, 2021). Overdrafting not only diminishes water availability but also concentrates pollutants, further compromising groundwater quality.
Pollution concerns are compounded by urbanization and industrial activities. In San Diego, proximity to military bases, industrial facilities, and urban runoff contributes to the presence of pollutants like pesticides, pharmaceuticals, and heavy metals in groundwater sources (Luh et al., 2020). Nitrate contamination from agricultural fertilizers and septic systems also poses health risks, especially to infants and pregnant women, as high nitrate levels can lead to methemoglobinemia or "blue baby syndrome" (USEPA, 2018).
Climate change exacerbates these challenges by altering precipitation patterns and reducing recharge rates. Periods of drought lead to increased reliance on groundwater, intensifying over-extraction and risking long-term aquifer health. Moreover, higher temperatures can accelerate chemical reactions in soil and water, potentially increasing the concentration of certain pollutants (Gleick, 2014).
Efforts to address groundwater issues in San Diego include increased monitoring, implementing recharge projects, and advancing water conservation initiatives. Recycled water and stormwater capture are also being promoted to reduce dependence on over-stressed aquifers. The San Diego Water Authority emphasizes integrated management strategies that balance water use with recharge and pollution control to protect groundwater resources for future generations (San Diego County Water Authority, 2022).
In conclusion, groundwater in California and San Diego faces numerous challenges, including over-extraction, pollution, and climate impacts. Protecting this vital resource requires sustainable management practices, innovative water treatment and recharge techniques, and stringent pollution controls. Public awareness and regulatory measures are crucial in ensuring groundwater remains a reliable and safe water source for the future.
