Frequently Asked Questions

Lead is a naturally occurring metal that is harmful if inhaled or swallowed. Lead can be found in air, soil, dust, pottery, food and water.

Lead can cause a variety of adverse health effects if too much enters your body from drinking water or other sources. These effects may include increases in the blood pressure of some adults; delays in normal physical and mental development in babies and young children; and, deficits in the attention span, hearing, and learning abilities of children. The greatest risk of lead exposure is to infants and pregnant women.

Structures built before the lead ban will be at a higher risk. The lead ban went into effect in Texas in 1988. Plumbing installed before 1988 can have lead in the solder, pipes, faucets, or fixtures, which can leach into the water supply over time. 

Developments built in the past 35 years would have neither lead service lines nor private plumbing lines that are lead, but plumbing fixtures in the home or business could contain lead. From 1986 to 2014, plumbing fixtures could contain up to 8% lead to be categorized as, “Lead free.” However, current standards for “lead-free” fixtures allow no more than 0.25% of lead content.

The City of Sugar Land has no information on the type of material used in private plumbing lines inside homes and business. Customers who think their home or business could be at risk can hire a licensed plumber to perform an inspection. 

Customers may also be able to identify their plumbing material themselves using a key or coin and a refrigerator magnet:

Use a Key or coin to scrape a small area on the pipe. Check to see if a magnet will stick to the pipe. 

• If the scraped area is the color of a penny, the pipe is copper. A magnet will not stick to a copper pipe.
• If the scraped area remains a dull gray, and a magnet sticks to the surface, the pipe is galvanized steel.
• If the scraped area is shiny and silver, the pipe is lead. A magnet will not stick to a lead pipe.

Currently, in Sugar Land, we have no known lead service lines. Staff has completed an initial Lead Service Line Inventory for the each of the city’s four water systems. 

Staff conducted an extensive review of historical records to help determine service line construction materials. This review of historical records included construction and plumbing codes, city ordinances, county appraisal district records, capital improvement plans, water system maps, and all maintenance, inspection, and repair records pertaining to the water systems. 

In addition to the records review, Public Works staff gathered data on service line material through normal operations, such as repair and replacement of service lines and meters. Staff also utilized field investigation methods, such as excavation on both sides of the meter, to help identify unknowns where documentation of construction material could not be located. Field investigations were also used to verify the accuracy of historical records. Public Works staff completed approximately 11,500 field investigations on service lines that were installed prior to the 1988 lead ban.

No lead service lines were identified on either the customer-owned or city-owned portions of the service lines in any of the water systems. However, staff identified 110 service lines that are classified as Galvanized Requiring Replacement (GRR) in the City’s Main water system. All other service lines have been identified as non-lead.

If the service lines at your address are suspected to contain lead, you will receive a letter with additional information. 

Corrosive water can dissolve lead from plumbing materials in service lines and home plumbing. By using chemicals to control the corrosivity of the water, lead exposure can be reduced. The City of Sugar Land has a corrosion control plan, as part of the Lead and Copper Rule. The system’s corrosion control technique is to adjust pH so the treated water is non-corrosive to metal. Over time, this process has resulted in Sugar Land’s treated water forming a protective scale on the inside of pipes that prevents the leaching out of materials such as lead.

In 2021, TCEQ approved optimal pH ranges for the system to operate within at all times. Monitoring is performed every two weeks at the point where the treated water leaves each treatment plant and quarterly at locations throughout the distribution system. Results of this monitoring are reported to Texas Commission on Environmental Quality.

The City of Sugar Land conducts lead and copper testing, as required by the TCEQ. Samples are collected and analyzed every three years from each of the city’s water systems. The City of Sugar Land was awarded a reduced sampling schedule of every three years because we have repeatedly demonstrated that the water systems meet the federal government's requirements. To date, the 90th percentile results for all of the city’s sampling events have been well below the Action Level of 0.015 mg/l for lead. 

The City of Sugar Land is responsible for providing drinking water that meets all federal and state standards but cannot control the variety of materials used in plumbing components found in homes and other buildings. If you are worried about lead exposure, here are some steps you can take:

• Flush your tap water by letting the water run for several minutes if it has been sitting in your pipes for several hours, such as first thing in the morning or upon returning from work
• Use only cold water for drinking, cooking, or preparing baby formula
• Remove and clean faucet screens or aerators
• Use a filter certified to remove lead
• When replacing plumbing components or faucets, make sure the products have been tested and certified to “lead-free” standards

If you’re concerned your home plumbing may contain lead, you may want to have your water tested by a state-certified laboratory. 

A list of certified laboratories is available on the TCEQ website (TX Drinking Water Public Labs - Lead and Copper Testing - Google My Maps). Contact labs directly for information on cost and sampling bottles.

Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline 800-426-4791 or EPA’s website (https://www.epa.gov/ground-water-and-drinking-water/basic-information-about-lead-drinking-water). 

The Environmental Protection Agency identifies a Galvanized Requiring Replacement line as a galvanized service line that is or was at any time downstream of a lead service line. If the water system is unable to demonstrate that the galvanized service line was never downstream of a lead service line, it must presume there was an upstream lead service line. The lines identified as GRR in the city’s initial inventory are galvanized, customer-owned lines in the original part of Sugar Land, at homes built between 1905 and 1965. While the city-owned portions upstream of them have been identified as non-lead currently, records are unable to demonstrate that the city-owned portions were always non-lead.

Galvanized service lines that have absorbed lead can contribute to lead in drinking water. People living in homes with a galvanized service line that has absorbed lead may have an increased risk of exposure to lead from their drinking water. You can use the tips below to reduce your possible lead exposure.
