The use and management of drilling fluids and cuttings
Depending upon the location of the drilling activity, and nature and sensitivity of the receiving environment, the DME consider the range of non-toxic to slightly toxic is acceptable for drilling fluid toxicity. For example, using the WA test species Penaeus monodon, the 96 hour LC50 of a SBF (internal olefin) was observed as 21,709 mg L-1

NON
NON-TOXIC AND BIODEGRADABLE SURFACTANTS. The invention is the use and application of a system having a non-toxic and biodegradable surfactant, which is not ethoxylated and is built up from alkyl polyglycoside derivatives, for use in the oilfield industry to mitigate the release of toxic chemicals into the environment.

Technical Memorandum
Because drilling fluids consist largely of a bentonite clay-water mixture, they are generally considered non-toxic. Drilling fluid to be used will be a mixture of bentonite clay, water, and drilling additives (which may include a water softener, viscosities, filtration control additives, biopolymer gel and torque reduce).

which invariably change with depth (Ghazia, 2011). In addition, drilling fluids are to be non-hazardous to the environment and personnel. Drilling fluids are normally formulated in-situ by mixing the different additives in a dedicated storage tank, or less preferably, a sump that has been excavated within the drill site.
BURNBLOCK
Burnblock’s ingredients occur naturally in fruits and vegetables or are found in nature in their elemental form. 100% Biodegradable. Degrades naturally 100% with no adverse environmental effects. Non-toxic. None (0%) of the substances in our products is included in the list of Substances of Very High Concern – SVHC. PH-Neutral.
Arsenic in Drinking
Drilling depth explained 4% of the variation in arsenic concentration (R 2 = 0.04; n = 3,396). The results without adjustment for enrollment area showed no significant association between exposure to arsenic and risk for any type of cancer, except for non-melanoma skin cancer, for which higher arsenic exposure was associated with lower risk
BENTONITE MATERIAL SAFETY DATA SHEET
Non-toxic to aquatic plants Non-toxic to soil organism. Non-toxic to aerobic and anaerobic plants Non-toxic to aerobic and anaerobic living organisms and animals. SECTION 13: DISPOSAL CONSIDERATIONS: Bentonite and waste from residue can be disposed as non-toxic and inactive materials
RotoMetals Bismuth Non Toxic alternative to lead
Bismuth Shot. NEW & PROUDLY MADE IN THE USA! We are proud to introduce a Non Toxic Lead Free alternative Bismuth Shot for reloading. Rotometals Bismuth Shot is great for waterfowl and upland game birds where lead is now banned. Rotometals Bismuth Shot is a also a great alternative for lead free ballast weight and has a similar density to lead.

Welcome to Excellent Systems A/S
All PE products are manufactured in our factory in Denmark, DK-8544 Morke, and we have thus full control over the quality of the production, the working conditions for our employees, and the raw materials we use, i.e. we secure that all raw materials and dyes we use in our ramps are approved for food and totally toxic-free.
Contamination of Groundwater
Following rainfall, variations in groundwater turbidity may be an indicator of surface contamination. Can be caused by decaying leaves, plants, organic matter, copper, iron, and manganese, which may be objectionable. Indicative of large amounts of organic chemicals, inadequate treatment, and high disinfection demand.
Environmental impacts of produced water and drilling waste
Drilling waste. Waste from borehole drilling consists of crushed rock cuttings from the borehole and remnants of drill mud. The function of the mud is to lubricate and cool the drill bit, stabilize the borehole, control pressure, and bring cuttings to the platform. Drilling waste also comprises used drill mud that has lost its technical
Potential Well Water Contaminants and Their Impacts | US EPA
Heavy metals include: arsenic, antimony, cadmium, chromium, copper, lead, selenium and many more. Heavy metals can contaminate private wells through groundwater movement and surface water seepage and run-off. People that consume high levels of heavy metals risk acute and chronic toxicity, liver, kidney, and intestinal damage, anemia, and cancer.
Understanding and interpreting soils and soil boring reports
Refusal or termination of borehole occurs if the hammer does not advance for >50 blows/6 inches. Note the advancement (e.g. 50/2). Note refusal on logs. Note sample recovery if refusal is reached in a split spoon interval. Depth of groundwater: Record during and after drilling Note perched layers of water in sand or lignite.

practice the entire borehole is sealed with grout. Perforation of an artesian aquifer can cause large quanti-ties of water to press through the drill pipe disrupting the grout. To avoid drilling closed-loop boreholes into artesian aquifers, local hydraulic heads must be checked prior to drill-ing (Ditlefsen 2012).
