Lead Service Lines at GROSSO KRESSER WINERY

GROSSO KRESSER WINERY serves about 3,600 people in California. Like all water systems in the US, it is required to identify and report on lead service lines—the pipes that connect the main water line under the street to homes and buildings.

What we know about this water system

GROSSO KRESSER WINERY draws water from groundwater sources. The utility has not yet completed or made public a full inventory of lead service lines in its system. This means the number of lead, galvanized, or other types of service lines remains unknown.

An incomplete inventory is common, especially for smaller systems. Many water utilities across the country are still in the process of identifying their service lines, which can take years.

What happens next

Water utilities must complete lead service line inventories by specific federal deadlines set under the Safe Drinking Water Act. Once GROSSO KRESSER WINERY finishes its inventory, it will be required to:

  • Share the results publicly
  • Develop a plan to replace lead service lines
  • Prioritize replacement in areas with the highest risk (especially homes with children and pregnant women)
  • Secure funding to pay for replacements

If you're concerned about lead in your home

Lead can enter drinking water through corroded service lines or household plumbing. The most reliable way to know if you have a lead service line is to:

1. Contact GROSSO KRESSER WINERY directly and ask about your property's service line material. 2. Request a free water test if you're worried about lead levels in your tap water. 3. Check your home's records or have a plumber inspect the service line on your property.

If you have young children or are pregnant, the CDC recommends having your water tested. A pediatrician or your local health department can also advise on next steps.
