Rose City Labs provides water tests for a variety of needs and industries, whether you’re testing your water for Real Estate Transactions, Financing, Regulatory requirements or safety or water quality concerns. We are ORELAP certified for well water testing and accredited for heavy metals testing in drinking water. We can also provide GSA reports for Legionella testing. We test schools and daycare centers for lead in accordance with EPA guidelines. We are NRSB certified for radon in water testing, and ASSE 120-80 certified for Legionnella in water testing.

The most common sources of water contaminants include:

• Naturally occurring chemicals and minerals

• Local land use practices such as fertilizers and pesticides

• Manufacturing processes

• Malfunctioning wastewater treatment systems

WHY DO I NEED MY WATER TESTED?
Testing drinking water quality on a regular basis is an important part of maintaining a reliable and safe water source. Although public water supplies are tested regularly, contaminants in drinking water can come from inside the home’s pipelines. Lead, arsenic, copper, and other substances can enter drinking water through corrosion of plumbing materials, especially where the water has high acidity or low mineral content that corrodes pipes and fixtures. Homes built before 1986 are more likely to have lead pipes, fixtures and solder.

Well testing is required for the sale or transfer of any home in Oregon that gets its drinking water from a well water source. Well water testing may also be required for government loans like VA or FHA loans. We are ORELAP certified to test wells under The Domestic Well Testing Act (ORS448.271) which requires testing for sale or exchange of real estate with a domestic well. The seller must test the well’s water quality for arsenic, nitrate, & coliform bacteria and share the results to comply.

Rose City Labs tests for 59 different pesticides. Pesticides applied to crops and landscaping have the potential to contaminate drinking water. They can make their way into water systems that feed drinking water supplies. The risk posed by your exposure varies based on: types of pesticides used, toxicity, concentrations in the water, and amount of daily exposure.

Abamectin, Acephate, Acequinocyl, Acetamiprid, Aldicarb, Azoxystrobin, Bifenazate, Bifenthrin, Boscalid, Carbaryl, Carbofuran, Chlorantraniliprole, Chlorfenapyr, Chlorpyrifos, Clofentezine, Cyfluthrin, Cypermethrin, Daminozide, DDVP (Dichlorvos), Diazinon, Dimethoate, Ethoprophos, Etofenprox, Etoxazole, Fenoxycarb, Fenpyroximate, Fipronil, Flonicamid, Fludioxonil, Hexythiazox, Imazalil, Imidacloprid, Kresoxim-methyl, Malathion, Metalaxyl, Methiocarb, Methomyl, Methyl parathion, MGK-264, Myclobutanil, Naled, Oxamyl, Paclobutrazol, Permethrins, Phosmet, Piperonyl_butoxide, Prallethrin, Propiconazole, Propoxur, Pyrethrins, Pyridaben, Spinosad, Spiromesifen, Spirotetramat, Spiroxamine, Tebuconazole, Thiacloprid, Thiamethoxam, Trifloxystrobin

We are ORELAP certified to provide well water sampling and arsenic testing required for real estate transactions under the Domestic Well Testing Act (ORS 448.271), and test schools and day care centers for lead in accordance with EPA guidelines. Rose City Labs is also licensed and accredited to test for heavy metals in drinking water. We can perform full heavy metals panels for water, which are also available in our testing kits.

We test for 14 elements:

• Arsenic
• Beryllium
• Cadmium
• Chromium
• Cobalt
• Copper
• Lead
• Manganese
• Mercury
• Nickel
• Selenium
• Thallium
• Uranium
• Vanadium
• Zinc

Coliform bacteria is a family of bacteria that occurs commonly in nature. Fecal Coliform bacteria occur in the intestines of humans and animals. E. coli is a subgroup of fecal bacteria that can cause severe illness. Runoff and flooding can pollute water supplies. Private wells are a greater cause for concern because many don’t have a way to disinfect water. Rural water supplies are the most likely to be contaminated. Although public water systems use chlorine, ultraviolet light or ozone to kill E. coli, some E. coli outbreaks have been linked to contaminated municipal water supplies.

“Groundwater contamination is a serious issue in some areas of Oregon. Many agencies study the quantity and quality of Oregon’s groundwater resources. Ambient groundwater quality studies over the past 20 years and routine monitoring of public water supplies found 35 of 45 study areas show some impairment or reason for concern. Nitrate is the most commonly detected contaminant, followed by pesticides, volatile organic compounds, and bacteria. Data collected show that twenty-four percent of 1156 wells sampled statewide exceed the drinking water standard for arsenic. Sixteen percent of 2187 wells sampled exceed the drinking water standard for nitrate. Thirty-three percent of Willamette Valley rural wells contain at least one pesticide.”

Waste can enter the water through different ways, including sewage overflows, sewage systems that are not working properly, polluted storm water runoff, and agricultural runoff. Wells may be more vulnerable to such contamination after flooding, particularly if the wells are shallow, have been dug or bored, or have been submerged by floodwater for long periods of time. Nearly 23% of Oregonians rely on private wells as their primary source of drinking water. This makes groundwater and well protection important to Oregon's public health. The Domestic Well Testing Act (ORS 448.271) requires testing for sale or exchange of real estate with a domestic well; a well used for drinking, cooking, washing, or bathing. The seller must test the well's water quality for arsenic, nitrate, & coliform bacteria and share the results to comply. Results are good for one year.
