However, a lot of…, Is a radiation dose of 620 millirem (or 0.62 Rem) in a year harmful?, No. No effects have ever been observed at doses below 5,000 millirem (5 Rem) delivered over a one-year period. In fact, effects seen when humans are exposed to 100,000 millirem (100 Rem) over a short time period are temporary and reversible. It takes a short-term dose of well over 500,000 millirem (500 Rem) to cause a fatality.

Q. What are the required levels for pH and Chlorine?, A. pH is 7.0 to 7.8, Chlorine is 1 to 8 ppm (parts per million)., Q. How do I dispose of old pool chemicals?, A. Questions concerning disposal of chemicals should be referred to the Bureau of Land and Waste Management (803) 896-4000. Some municipalities and water treatment facilities may be willing to take expired HTH to use in their treatment procedures., Q. How do I keep chlorine/bromine levels within the required range between absence of swimmers and full bather load, ? A. Maintaining a free available chlorine residual between 1.0 and 8.0 ppm should be attainable if proper monitoring is conducted. If you anticipate a high bather load, simply monitor and adjust as needed. Even extreme bather loads should not decrease the halogen level to a point of being out of compliance unless routine monitoring is not conducted properly., Q. What is the lifeline requirement when I have lap swimming and children in the pool at the same time?, A. According to Reg. 61-51, if lap swimming is taking place, it is fine for the lifeline to be removed. If there are children swimming in the pool at the same time that lap swim is taking place, it is recommended that the line be in position in the children's swimming area. The lifeline must be replaced as soon as lap swimming is over., Q. Shouldn't rescue tubes be a mandatory part of the life-saving equipment at all pools since lifeguards are trained with them?, A: Rescue tubes are only required at pools where lifeguards are required (type A and E facilities)., Q. My spa's automatic controller digital readout is given as an oxidation reduction potential (ORP) level instead of a parts per million (PPM) level. How do I equate the two readings?, A. Generally experts recommend that an automatic controller's ORP level be set between 650 mV and 750 mV. However, factors such as system calibration accuracy and other water chemistry parameters (cyanuric acid levels) may affect the ORP readings. If you have specific questions about your controller and its ORP readings, contact a qualified pool or spa service representative. Please remember that…Swimming Pool Permitting and Compliance

This webpage is no longer maintained. It may be useful as background information or to provide a historical perspective on a topic or project. , On, July 25, 2012, , DHEC staff visited residents on Easy Street, Howe Street and Corning Road to request permission to collect soil samples from their front and/or back yards. Samples were also collected from nearby businesses and other public locations. Samples were taken from: 41 houses (52 total samples), 6 businesses (18 total samples), 2 parks (8 total samples), and 7 samples from public rights-of-way. DHEC…, July 30, 2012, to share the findings of the soil sampling. Residents whose samples showed elevated levels of arsenic and/or lead were given a hand-out on how to reduce their exposure until a soil cleanup action could be coordinated. DHEC recognized that knowing the contamination had spread beyond the former Royster property would be unsettling and upsetting to many families., DHEC’s first priority was to ensure the safety of all affected residents., DHEC swiftly confirmed that the communities surrounding the former Royster site were served by a public water system and communicated to residents that the, contamination did not pose a risk to those who drank, prepared food, bathed or irrigated with water supplied by a public water system., Blood & Urine Testing Provided to Residents, Due to the elevated levels of lead and arsenic that were found in soils of the Edisto Court Community, DHEC offered free urine testing for arsenic, and blood testing for lead, to residents within the affected area (Easy Street, Howe Street and Corning Road). The testing was offered to determine any possible recent exposure to lead or arsenic. DHEC staff went door-to-door to provide information on…, The results of the testing indicated that all levels were within the normal range and no medical follow-up was required., Lead, arsenic and other metals naturally occurring in nature may be detectable in people. Levels found in the body that do not cause illness or disease, and do not require treatment or further investigation, are considered to be in the “normal range.” For questions or additional information about lead or arsenic toxicity, please contact Fran Marshall, SCDES State Toxicologist, at, (803) 898-9956, ., Notification of Final Phase of Cleanup on Commercial Properties, DHEC notified local residents by postcard that soil excavation work on the commercial properties along Commerce Drive had been completed and that this work included: Excavating contaminated surface soils (0 to 2 foot depth) that exceeded DHEC’s cleanup criteria of 39 mg/kg for arsenic and 800 mg/kg for lead; Transporting and disposing of excavated soils in a permitted landfill; and Restoring the…Saluda River NDPES Permit Renewal
Saluda River NPDES Permits - Renewal, DHEC has updated a water quality model for the Saluda, Broad and Congaree Rivers. This will require changes to discharges into these midlands rivers.
