About Us

Founded on the Promise of Purity

Water touches nearly every part of our daily lives. The bath your child soaks in, the glass they reach for after school, the meals you cook for your family every night. It should be the last thing you have to worry about, and yet for so many families, it has become one of the most overlooked risks inside the home.

That is exactly why I founded Pure Coast Water Company. To cut through the noise, eliminate the worry, and make genuinely safe water accessible to families and businesses at every budget level.

We operate within a 90-mile radius of San Diego, serving communities from San Ysidro to Los Angeles, including all of San Diego County, Temecula, Riverside, and the full I-5 and I-15 corridors. If you are in this region, we are your neighbors, and we are here to help.

Home Base

San Diego

San Diego tap water contains manganese and bromate levels flagged by the EWG as exceeding health guidelines. Whole-house filtration and reverse osmosis systems are the most effective solutions for cleaner, safer water at every tap.

South Reach

San Ysidro

Located at the US-Mexico border corridor, San Ysidro shares San Diego's aging water infrastructure concerns, including disinfection byproducts and elevated TDS levels that affect taste, odor, and long-term health.

South Bay

Chula Vista

Chula Vista water has 9 contaminants exceeding health guidelines including arsenic and hexavalent chromium, with hardness measuring 11 GPG and TDS levels near 740 ppm. A whole-house filtration system is strongly recommended for every home.

North County

Oceanside

Oceanside tap water tests up to 68 µg/L of TTHMs and uranium up to 4.2 pCi/L, with hardness ranging from 8 to 16 GPG depending on the source. Reverse osmosis and water softeners are widely recommended for Oceanside residents.

Inland North

Escondido

Escondido water contains HAA5, TTHMs, arsenic, and uranium exceeding EWG health guidelines. High calcium and magnesium levels create notably hard water that damages appliances, dries skin, and shortens the life of plumbing systems.

I-15 Corridor

Temecula

Temecula's water scores a C overall with 10 contaminants above EPA health guidelines, including chromium-6, arsenic, and radioactive radium from groundwater sources. Whole-house filtration is the most effective protection for Temecula families.

Inland Empire

Riverside

Riverside County water sources carry agricultural runoff contaminants including nitrates linked to infant health risks. Hard water and elevated TDS levels from mineral-rich groundwater make whole-house filtration essential for Inland Empire households.

Desert

Palm Springs

Palm Springs water testing revealed 9 contaminants above health guidelines including chromium-6, bromodichloromethane, and radium, serving over 210,000 Coachella Valley residents. Desert groundwater is among the hardest and most mineral-dense in Southern California.
