Radon occurrence in groundwater from 16 geologic units in Pennsylvania
Evaluation of radon occurrence in groundwater from 16 geologic units in Pennsylvania, 1986–2015, with application to potential radon exposure from groundwater and indoor air
Scientific Investigations Report 2017-5018
“Results from 1,041 groundwater samples collected during 1986‒2015 from 16 geologic units in Pennsylvania, associated with 25 or more groundwater samples with concentrations of radon-222, were evaluated in an effort to identify variations in radon-222 activities or concentrations and to classify potential radon-222 exposure from groundwater and indoor air. Radon-222 is hereafter referred to as “radon.” Radon concentrations in groundwater greater than or equal to the proposed U.S. Environmental Protection Agency (EPA) maximum contaminant level (MCL) for public-water supply systems of 300 picocuries per liter (pCi/L) were present in about 87 percent of the water samples, whereas concentrations greater than or equal to the proposed alternative MCL (AMCL) for public water-supply systems of 4,000 pCi/L were present in 14 percent. The highest radon concentrations were measured in groundwater from the schists, gneisses, and quartzites of the Piedmont Physiographic Province.

In this study, conducted by the U.S. Geological Survey in cooperation with the Pennsylvania Department of Health and the Pennsylvania Department of Environmental Protection, groundwater samples were aggregated among 16 geologic units in Pennsylvania to identify units with high median radon concentrations in groundwater. Graphical plots and statistical tests were used to determine variations in radon concentrations in groundwater and indoor air. Median radon concentrations in groundwater samples and median radon concentrations in indoor air samples within the 16 geologic units were classified according to proposed and recommended regulatory limits to explore potential radon exposure from groundwater and indoor air. All of the geologic units, except for the Allegheny (Pa) and Glenshaw (Pcg) Formations in the Appalachian Plateaus Physiographic Province, had median radon concentrations greater than the proposed EPA MCL of 300 pCi/L, and the Peters Creek Schist (Xpc), which is in the Piedmont Physiographic Province, had a median radon concentration greater than the EPA proposed AMCL of 4,000 pCi/L. Median concentrations of radon in groundwater and indoor air were determined to differ significantly among the geologic units (Kruskal-Wallis test, significance probability, p<0.001), and Tukey’s test indicated that radon concentrations in groundwater and indoor air in the Peters Creek Schist (Xpc) were significantly higher than those in the other units. Also, the Peters Creek Schist (Xpc) was determined to be the area with highest potential of radon exposure from groundwater and indoor air and one of two units with the highest percentage of population assumed to be using domestic self-supplied water (81 percent), which puts the population at greater potential of exposure to radon from groundwater.
Potential radon exposure determined from classification of geologic units by median radon concentrations in groundwater and indoor air according to proposed and recommended regulatory limits is useful for drawing general conclusions about the presence, variation, and potential radon exposure in specific geologic units, but the associated data and maps have limitations. The aggregated indoor air radon data have spatial accuracy limitations owing to imprecision of geo-coded test locations. In addition, the associated data describing geologic units and the public water supplier’s service areas have spatial and interpretation accuracy limitations. As a result, data and maps associated with this report are not recommended for use in predicting individual concentrations at specific sites nor for use as a decision-making tool for property owners to decide whether to test for radon concentrations at specific locations. Instead, the data and maps are meant to promote awareness regarding potential radon exposure in Pennsylvania and to point out data gaps that exist throughout the State.”

Pennsylvania Ticks – Yes they are a problem
Pennsylvania has led the nation in confirmed Lyme disease cases each year since 2011. When detected early, Lyme disease and other tick borne diseases can be treated. Left untreated, tick borne diseases can cause a whole host of problems. Early diagnosis is important in preventing long term complications.
After coming inside, always check yourself for ticks. The target areas, head and hair, armpits, back of knees, and waist line/middle of the body, are prime spots to find a tick as they seek out out-of-the-way crevices and warm spaces. Look closely, they are smaller than a freckle.
If a tick does manage to attach itself to you, use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.
Pull upward with steady, even pressure. Avoid twisting or jerking. Clean the bite area and see a physician. If possible – Save the Tick!

PASPGP-5 Training Marcellus Shale Coalition General Permit 5 Stream and Wetlands Encroachments
PASPGP-5 Training
Wednesday, July 27, 2016
4.5 Professional Development Hours (PDH) available!
The Marcellus Shale Coalition is pleased to offer to all oil and gas industry stakeholders the opportunity to attend a training session on the recently released Pennsylvania State Programmatic General Permit 5 (PASPGP-5).
Section 404(e) of the Clean Water Act (CWA) (33 U.S.C. §1344) provides for the issuance of Department of the Army (DA) general permits (GP) on a statewide basis, which operate in conjunction with a State regulatory program that protects the aquatic environment in a manner equivalent to the DA regulatory program, provided that the activities permitted under each category of such GPs are similar in nature and result in no more than minimal individual or cumulative adverse effects on the aquatic environment.
The Commonwealth of Pennsylvania’s Dam Safety and Waterway Management Rules and Regulations establish a statewide permit program for protecting the waters of the Commonwealth. The Commonwealth’s procedures for the granting of permits require the PA DEP to apply evaluation criteria consisting of alternatives analysis (for non-water dependent activities), avoidance techniques, the minimization of impacts, and if a permit is to be granted, compensatory mitigation. The evaluative criteria within the Commonwealth’s program are similar to Federal criteria under Section 404(b)(1) of the Federal Clean Water Act.
The PASPGP-5, effective on July 1, 2016, authorizes impacts to stream and wetland encroachments and crossings in Pennsylvania. During this training, attendees will be educated on the requirements within PASPGP-5. Additionally, an update on the proposed wetland and stream assessment protocols that were released for public comment in 2014 and are approaching finalization will be discussed. Lastly, industry experts will present case studies that will demonstrate five methods for pipeline stream crossings and review lessons learned.

Environmental Health Product – Tri-Heat Heating Pad
Since I am getting Older – I came across this product seems interesting at our local BNI Business Meeting – Where I was speaking about the Know Your H20 Program and it is part of our BUY Local and Support Local Business Efforts.
Tri-Heat is a new style heating pad that was designed to help people with muscle, joint and arthritic pain find a more comfortable and effective way of applying heat therapy.Heat application is a commonly prescribed therapy in today’s medical field and Tri-Heat’s unique design makes it perfect for treating pain in hard to target areas such as the neck, wrist, shoulder, elbow and knee, among others.
Traditional heating pads are flat, flimsy and offer no support. When you try to wrap them around the injury you have to struggle to hold them in place and fit them to your joints. When you constantly have to readjust them you lose the heat and therefore any benefit they offer.
Tri-Heat is different. When you place it in the area that needs treatment you don’t have to adjust it or struggle to make it fit into the muscle and joint because the design allows it to comfortably stay in place and heat effectively. It’s great for Arthritis sufferers, as well as athletes looking to warm up their leg, arm, and shoulder muscles before a big game.
Tri-Heat comes with:
- 4 Heat Settings
- Moist Heat Capability
- Two Heated Sides
- 40 Min. Auto Off

Installing a Rain Garden
Install a rain garden in your community – Possible ROAs for a Groundwater Guardian Project
Spring is just around the corner, and a great time to think about installing a rain garden. A rain garden is a garden of native shrubs, perennials, and flowers planted in a small depression, which is generally formed on a natural slope. It is designed to temporarily hold and soak in rain water runoff. Rain gardens help filter out pollutants such as fertilizers, chemicals, bacteria, and others contained in runoff. They also incorporate native vegetation, reducing the need for fertilizers and after the first year, maintenance is usually minimal.
Rain gardens are effective in:
- removing up to 90% of nutrients and chemicals
- removing up to 80% of sediments from rainwater runoff
- allowing for 30% more water to soak into the ground than a conventional lawn
Consider installing a rain garden as one of your team’s 2016 Result-Oriented Activities. Remember, you can add an ROA at any time during the year. Involve the public and make it an educational event! Read more about how rain gardens benefit a community and how to get started.
