The Modesto Water Contamination Lawsuit is an active lawsuit
See If You Qualify

Per- and polyfluoroalkyl substances (PFAS), often called “forever chemicals,” can remain in the environment, and the human body, for extremely long periods. In turn, long-term exposure to these chemicals can pose potential health risks. PFAS has been linked to serious conditions such as kidney, liver, and testicular cancers, thyroid disease, ulcerative colitis, and more. Regrettably, these contaminants have been found in Modesto, California’s water supply. As a result, there are ongoing concerns about the safety and quality of the area’s drinking water.

Many Modesto residents exposed to PFAS and other contaminants in the water have filed lawsuits against manufacturers. With the help of King Law, they are seeking compensation for the harm they may have suffered. If you believe you are one of them, King Law may be able to help you, too.

Modesto, California Water Contamination Overview

Located in the heart of the San Joaquin Valley, Modesto has deep roots in agriculture. Indeed, Stanislaus County is one of California’s largest agricultural regions. Still, Modesto’s proximity to Silicon Valley and Sacramento has also made it a hub for industry.

Modesto’s motto, “Water Wealth Contentment Health,” highlights the role of water in the city’s agricultural legacy. Like much of arid central California, Modesto relies on a secure and clean water supply. In recent years, though, concerns about the safety of the city’s water have grown. Pesticide use, industrial runoff, spills, and pollutants have introduced contaminants to the local water. In turn, these contaminants may pose significant health risks. The Environmental Protection Agency (EPA) has even designated certain areas around Modesto as superfund sites. These areas require extensive cleanup due to hazardous pollution. Among the most pressing water contamination concerns is the presence of PFAS chemicals. King Law is helping many Modesto residents affected by PFAS to seek compensation.

About Modesto, California Water Contamination:

History of Water Contamination in Modesto, California

Modesto, California, has experienced longstanding challenges related to air quality, water contamination, and other environmental problems. The area’s water issues are closely related to its status as a large agricultural producer. Pesticides, fertilizers, and agricultural runoff in the area have added contaminants, such as nitrates, to the area’s water. Bad irrigation practices and animal waste are contributors to the area’s water contamination.

Also, contaminants from local industries may infiltrate the water supply. Industrial waste can seep into water sources in often unexpected ways. EPA-designated superfund sites have appeared in the area for many years. More recently, however, long-lasting PFAS chemicals have become a greater cause for concern. These chemicals, used in products such as non-stick cookware and firefighting foam, are linked to cancer, thyroid disease, and other serious issues.

Sources of Water Contamination in Modesto

Many of the contaminants in Modesto’s water come from the area’s agricultural industry. Chemical fertilizers and pesticides frequently contain nitrate and other chemicals that may contaminate the water. Storm runoff and improper irrigation can add other contaminants to the water. 

Chemical contaminants may also enter the water supply from industrial sources. Many of these chemicals can harm those who experience long-term exposure. For example, a dry cleaning facility in the area substantially contaminated local groundwater with tetrachloroethylene (PCE). PCE may increase your risk of various cancers, organ damage, nervous system problems, and more. As a result, the EPA designated the affected area a superfund site. Receiving a superfund area means that the EPA knows that the area requires substantial cleanup and monitoring.

Modesto Water Contamination Map

Water contaminants, including PFAS chemicals, continue to affect Modesto’s water supply. This water contamination map shows various sites of pollution affecting the area.

Contaminants Found in Modesto Drinking Water

On the one hand, the contaminants in Modesto’s water meet various safety standards. However, the Environmental Working Group’s (EWG’s) Health Guide demonstrates that many of these contaminants far exceed their recommended safety limits. Some of the contaminants present in Modesto’s water include:

Arsenic

Arsenic — a known carcinogen and poison — is a naturally occurring mineral. It enters water naturally, as well as from agricultural and industrial sources. Long-term exposure to arsenic may increase your risk of skin cancer, bladder cancer, lung cancer, diabetes, and heart disease, among other conditions. Arsenic has been found in Modesto’s water at a level 228 times higher than the EWG’s health guide.

Chloroform

Chlorine is commonly used in the water treatment process. However, when Chlorine reacts with natural substances and decaying matter in the water, chloroform may form. Prolonged exposure to chloroform may increase your risk of cancer, kidney problems, liver damage, and nervous system harm. It may also cause problems with pregnancy and result in birth defects. Chloroform levels in Modesto’s water have been found to be 45 times higher than the EWG’s recommended levels. 

Per- and poly-fluoroalkyl substances (PFAS)

For years, manufacturers have used PFAS chemicals in various consumer products. Products that might contain PFAS include nonstick cookware, cleaning chemicals, firefighting foam, and food packaging. These chemicals can remain in the environment and the human body for many years, even decades). Even low-level exposure to PFAS contaminants may increase your risk of cancer, thyroid disease, ulcerative colitis, and other health issues. In children, the chemicals may also cause weakened immune systems. Testing on Modesto’s water has revealed PFAS levels that exceed proposed safety limits. For instance, water samples show a concentration of the chemical PFOS at levels up to 11.0 ppt. However, the recommended safe level is 4.0 ppt or lower.

Nitrate

Nitrate is a nitrogen compound. It often appears in wastewater, chemical fertilizers, septic tanks, and animal manure. Given the widespread use of fertilizers, the risk of nitrate contamination entering local water is a risk. Exposure to nitrate may raise someone’s risk of multiple cancers, including colorectal, ovarian, thyroid, kidney, and bladder cancer. In Modesto, nitrate has been detected in the water at a level 35 times higher than the EWG’s recommended safety limits.

Other Contaminants

Various other contaminants have appeared in Modesto’s drinking water. Each presents potential health risks. These chemicals include:

  • Bromodichloromethane: Bladder cancer and other cancers, fetal development problems
  • Chromium: Stomach cancer, liver damage, reproductive system damage, lower body weights in children
  • Dibromoacetic acid: Cancer, problems with pregnancy
  • Dibromochloromethane: Cancer, problems with pregnancy
  • Dichloroacetic acid: Cancer, problems with pregnancy
  • Haloacetic acids (HAA5 & HAA9): Cancer, harm to pregnancy
  • Radium: Cancer
  • Trichloroacetic acid: Bladder cancer, skin cancer, harm to fetal development
  • Uranium: Cancer, kidney damage

Current Water Quality in Modesto, California

Modesto, California’s water meets all federal water safety standards. However, PFAS and other contaminants threaten the area’s water supply. Just because contaminants meet safety standards, that does not mean it is contaminant-free. As a result, locals will likely need to continue to use caution when consuming local water.

Water Treatment Efforts in Modesto

To address water contamination from agriculture, runoff, industrial waste, and other pollutants, Modesto has implemented various treatments. For example, the city has undertaken reverse osmosis and ion exchange to help remove nitrate from the water. In addition to nitrate, ion exchange can also remove PFAS from the water. However, ongoing monitoring may likely remain necessary as the area addresses the effects of PFAS.

Health Risks and Symptoms Linked to Drinking Water at Modesto

Even with advanced testing and treatment, PFAS contaminants and other chemicals continue to threaten Modesto water. Even at trace levels, many of these contaminants may increase individuals’ risks of:

  • Kidney problems
  • High cholesterol
  • Thyroid disease
  • Weakened immune systems
  • Endocrine and hormonal disorders
  • Kidney cancer
  • Testicular cancer
  • Prostate cancer
  • Skin cancer
  • Lung cancer
  • Ovarian cancer
  • Liver disease
  • Pregnancy-related high blood pressure
  • Low birth weights
  • Birth defects
  • Neurological problems
  • Cardiovascular disease

Those vulnerable to illness, such as pregnant women, the elderly, and children, may face increased health risks from water contamination. People with pre-existing conditions and weakened immune systems may also be at risk. Still, anyone who experiences ongoing exposure to such chemicals may develop health problems.

Regular checkups and screenings can help detect conditions potentially associated with PFAS exposure. However, such care — especially for a serious condition — is likely to be expensive (even if you have health insurance). Still, if you file a PFAS lawsuit, you may be able to recoup compensation to help with your medical bills.
