Weekly Chlorine Residual Average
The Kansas Department of Health and Environment (KDHE) requires Kansas municipalities to take daily water samples from different water zones within their water distribution systems to monitor changes in chlorine levels.
Water operators take water samples every day from Spring Hill's four zones to test for chlorine residuals from strategically predetermined locations within these zones. KDHE requires a chlorine residual range between 1.0 and 5.0.
The City's residual average for the week of June 4 through June 10 is 2.1 mg/l (this number is updated weekly).
Annual Consumer Confidence Report
Every year, laboratory analysis testing of contaminants in our water is completed and results of these tests are compiled into a water quality report. The results are made available to all residents, businesses, and industrial customers within the Spring Hill Water District (District map). For more information on water quality testing results within the City of Spring Hill, please view the 2017 Consumer Confidence Report.
Monthly Bacteriological Testing
Monthly water samples are also taken from within the different water zones and mailed to the KDHE laboratory to test for bacteria, which is an indication of possible contamination. If a test result is positive, further bacteriological testing is required, and City residents would be notified to boil their water until bacteriological testing was completed and the water was deemed safe to drink by KDHE.
Lead and Copper Testing
Due to the use of lead and copper in pipelines and plumbing solder in past years, these contaminants have the possibility of leaching into the drinking water. Spring Hill's water systems are monitored for lead and copper on a scheduled basis to ensure that our water meets federal regulations for both lead and copper in drinking water. In 2014, organic chemistry reports of analysis have shown all local samples to have well below to not detectable results for these heavy metals.
Trihalomethane and Haloacetic Acids Testing
Chlorine introduced into potable water systems kill bacteria. This is necessary to provide safe water to drink. As a result, the dead bacteria (disinfection byproduct) remains in the water.
The Environmental Protection Agency (EPA) developed two federal rules regulating disinfection byproducts. The Stage 1 Disinfectants and Disinfection Byproducts Rule (Stage 1 DBPR) establishes maximum contaminant levels (MCLs) for Total Trihalomethanes (TTHM) and Haloacetic Acids (HAA5).
The City began testing for TTHM and HAA5 in the last quarter of 2013 and will be sampling each quarter (once every three months) of each year thereafter.
